How Do Solar Panels Work?

Understanding how a solar panel works is a simple idea with a complex execution. The use of a solar panel in an array is pretty straight forward. The sun hits the solar panels, and the ultraviolet (UV) light wavelengths converts into usable electricity.

However, how the light from the sun converts into electricity is a bit more complicated. Knowledge is king when looking into solar, which is why Go Solar Group wants to make sure interested parties understand how solar panels work.

How Do Solar Panels Work? Residential Solar Power for Beginners

Just like other industries, solar experts have solar-related jargon that few outside the industry understand. Solar terms, like inverter, kilowatt, power grid, and monocrystalline, aren’t typically used outside of solar and other energy-related industries.

As a newbie to solar, it is helpful to know the basics. Understanding the basic idea behind how solar works helps customers feel comfortable considering solar for their homes and comparing solar companies.

The Epicenter of Solar Power – the Sun

Just like everything else in our galaxy, solar panels begin with the sun. This gigantic mass of energy fuses hydrogen into helium. As a result, it emits different wavelengths of light on the earth.

Of these light wavelengths, 99 percent are in the form of visible light, which are composed of ultraviolet rays and infrared rays. UV rays have shorter wavelengths and therefore are more energetic than the other rays emitted from the sun.

Solar panels capture these active rays and convert them into electricity. The sun lights up our planet, and with solar panels, it can also light up our lives.

How Solar Panels Generate Electricity

Each residential solar panel has roughly 60 cells. Each cell has electrons that create an interplay of electrical motility when the photons in UV rays hit them, which produces an electric current. 

While this is the basics of how solar panels generate electricity, remember, there are many determinants of a solar panel's ability to produce energy for homes, including, but not limited to, roof space. Solar panel function isn't the only aspect of solar worth assessing when considering rooftop solar.

Types of Solar Panels

Solar panel comparisons aren’t as straightforward as some products, like cars, when it comes to prospects’ understanding. Because most need a car at some point, the differentiating components in a car are often well known. For instance, families who are looking, know they need space, while a commuter is looking for good gas mileage.

However, when it comes to solar panels and the manufactured materials, these items rarely mean anything to homeowners considering rooftop solar. While each solar panel type has several differences, efficiency is what sets them apart for the customer. Determining the efficiency of solar panel types is mostly about the electrons’ ability to potentiate energy within the solar cell.

Monocrystalline Solar Panels

If we hyphenate the word monocrystalline, it’s easier to deduce the meaning of this term. Mono-crystalline means one crystal.

The solid crystals in monocrystalline solar panels give the electrons more movement within the panel, making them more efficient. Most crystalline solar panels use silicon as this crystal. These solar panels are manufactured by melting the silicon and dipping a crystal of silicon into the liquid, forming an ingot. The ingots slice into silicon wafers, which form the square-like shapes in the solar panel.

Polycrystalline Solar Panels (Also Referred to as Multicrystalline Solar Panels)

In the same steps as we underwent with monocrystalline solar panels above, hyphenating the word polycrystalline and multi-crystalline (poly-crystalline and multi-crystalline) reveals these kinds of solar panels are made by multiple crystals or crystalline processes.

Although the manufacturing for polycrystalline panels is similar to monocrystalline in that they each rely on melted silica, The difference is that the silicon is allowed to cool, and the panels are melted together.

These panels are slightly less efficient and cheaper to make than monocrystalline panels and are therefore the main product that most solar companies use. Melting many fragments of silica together as solar panel manufacturers do when making polycrystalline panels, makes for less room for the electrons to move fully throughout the cell of the panel, creating a less efficient form of solar energy production for homeowners, even in sunnier cities, like Reno, Nevada.

Amorphous Thin-film Solar Panels

Thin-film panels are made by putting a photovoltaic substance onto glass or another like material. These panels have the lowest efficiency. If you have a lot of space then these might be a good cheaper option to the other two panels above. Overall thin-film panels are not the best option for a home solar installation. Although there are a few instances where amorphous, thin-film solar installation is the best option, solar installers generally try to avoid relying on this kind of energy transduction whenever possible, and for the following reasons.

Residential Solar Installation can take longer with thin-film solar panels

Using these kinds of solar panels can sometimes increase the cost of installation, as most solar installers are trained to handle more relevant and more modern forms of residential rooftop solar install, which brings us to our next point regarding innovation and thin-film solar panels.

Amorphous Panels are Past Their Prime, and Are Abandoned by Innovators in the Solar Energy Field

Although thin-film solar panels received recognition and where applied to solar projects in the 1990s, they’ve been left behind as a portion of the solar panel innovation pipeline, making their technology largely defunct and irrelevant in the 21st century solar energy landscape.

Only adding to this equation is the fact that these kinds of solar panels haven’t withstood the test of time in harsh conditions, which is the case for both Monocrystalline and Polycrystalline solar panels. Although polycrystalline is less efficient, it’s withstood rough conditions in space travel and inclement weather.

Nanocrystalline Solar Cells

These include organic conductors that are not limited to silica like the other kinds of solar modules discussed above. The thin film of the nanocrystals needed to create these kinds of solar cells is detailed in a process called “spin coating.”

Although these kinds of solar cells are yet to proliferate in mass, recent solar cell research conducted by the National Renewable Energy Laboratory and Expounded on by researchers at the Massachusetts Institute of Technology declares these kinds of panels have an extraordinary chance of becoming the solar cell technology of our future not just in residential solar, but in commercial and government research solar as well. Researchers at the National Renewable Energy Laboratory have also drawn the same conclusions.

Found to be promising as early as the 1990s, these photovoltaic cells have been found to demonstrate greater efficiency in leveraging light energy into electrical currents, which is made even more viable by the potentially low cost of the materials that’d be needed to build these for homeowners in rooftop solar.  Sensitized by transparent dye, this method of solar technology will bring a new wave of research and practical application to the world of solar energy within the next decade.

How do Solar Panels Convert Solar Energy into Electrical Energy? The PV/Solar Inverter

Without the inverter, solar panels would be useless. The panels are connected to the inverter, which is then connected to your home (and battery backup where applicable), and, ultimately, the power grid. On a more technical level, solar panels may sometimes have electronics inserted into their photovoltaic (PV) structure to facilitate a maximum power point tracking (MPPT) mechanism.

This mechanism continually ensures electrical output every five to ten minutes, guiding the panels’ production. At a more basic level, the inverter is what turns alternating current to direct current.

Believe it or not, solar panels are just a small component of a complex process. The various types of inverters play nuanced and distinct roles in turning direct current absorbed by solar panels into alternating current usable in homes and commercial buildings alike.

String Inverters

Essentially, a string inverter takes the direct current from an array of solar panels and transforms it into potentiated alternating current. The central drawback of a string inverter is the fact that maladies in shading or other sunlight hindering absorption processes detract from the entire solar panel system’s output. For some homeowners, cutting down or trimming the trees around their home is enough for their solar service team to justify installing a string inverter.

String inverters work well with panels installed on roofs in string-like blocks (such as 4 rows with 4 panels per row), and in one location on a roof. String inverters tend to work well for unobstructed rooftops with a large surface area.

If you want more information on monitoring your existing SMA string inverter, see this video with one of our solar technicians explaining the SMA set up.

Central Inverter

These kinds of PV inverters are like string inverters, but much larger and designed to support bigger strings of solar panels. These inverters require less wiring and conduit connectivity but need a combiner box. These kinds of inverters are meant for commercial-grade solar installs.


The microinverter is installed on each panel of a rooftop solar system, converting sunlight at the level of the panel, which is different from a string inverter, which converts the current further along in the process.

Micro-inverters manage each solar panel individually. Micro-inverters convert direct current to alternating current immediately, scaling up on the retention of solar energy to get maximum impact out of the panels,  and on a solar panel-by-solar panel basis.

The microinverter also makes additions to the rooftop in terms of the number of panels easier to achieve should production not be as high as expected. Additionally, microinverters, much like traditional laptops, monitor their IP addresses (basically the equivalent of the phone book for the Internet), so solar installation technicians can monitor a system’s production remotely and resolve any issues that arise with an inverter.

Power Optimizers and String Inverters: A Newfound Trend

Microinverters and optimized string inverters are different than string inverters. While a typical inverter like an SMA Sunny Boy will be more efficient at the peak sunlight hours of any given day, a SolarEdge optimized string inverter will give solar homeowners consistent power throughout the day.

Power optimizers are frequently coupled with string inverters on a module-by-module basis, increasing the efficiency of the conversion of the electrical current. Power optimizers increase the current before sending it to the inverter, which improves the power efficiency of a residential solar system.

The SolarEdge inverter, which Go Solar Group uses, is an Israeli-engineered string inverter with optimizers. The biggest benefit of using the SolarEdge inverter is the panels can transduce a greater amount of sunlight in the shade than an SMA Sunny Boy inverter.

This option also works better for rooftops affording limited space for solar panels. If a roof is small, an optimized string inverter will work more efficiently than an SMA Sunny Boy.

This is the case because the conversion of the electrical current is happening on a module by module basis. If a home has a lot of shade or little exposure to sunlight, the optimizer keeps one maladjusted panel from affecting the output of the remaining solar panels atop a home.

Battery Backup: How to Get the Most out of Declining Net Metering Returns

Battery backup is a battery that is charged by the excess energy that your solar array produces. Getting enough battery back up to meet all your energy needs is ideal, but unfortunately not the most affordable option.

If you would like to start off small, getting emergency battery backup will give power to your essential electronics and appliances for several hours. Go Solar Group offers an emergency backup option with each system installed.

Battery backup for residential installations has been the best option for people that need an off the grid system. It is close to the same price or slightly cheaper than having power lines brought to your remote location and provides people with the tools to become self-reliant.

Unfortunately, this is not an affordable option for the average solar customer. Battery backup technology is slowly progressing and as time goes on more options at competitive prices will be available, but as of right now Tesla is leading the way.

Until battery backup is able to catch up to consumer needs and price range there is another option to help you stay afloat when the power grid is down. Emergency battery backup allows you to have power for a few essential items when the grid is down.

Go Solar Group is one of the few companies that offers an emergency backup option with every system installed. This provides you with security in an emergency or couple-hour blackout.

Whether you decide to get back up for solar array or not it is good to at least make sure that your system is compatible with battery backup.

Not all photovoltaic systems are built for battery backup since it isn’t a popular option right now. When battery backup prices go down, and they will go down, you want to make sure you can take advantage of it.

The Net Meter and Net Meter Number

A net meter is a device that measures what you put on and take-off of the power grid. A net meter is installed by your power company after you sign their net metering agreement. If you decide that getting battery backup for your whole home isn’t a good option for you a net meter will most likely be installed.

Because battery backup technology is still evolving into a more affordable option most people sign up for a net metering agreement. This agreement allows customers to use energy from the grid at night when they don’t have the sun and put their excess energy from their solar array during the day on to the grid.

Your power company decides how much of the power you put back onto the grid is credited back to you. What their rates are could be a determining factor of how big of a system you get and what forms of energy storage you choose.

The Power Grid

If you own a typical home, you are connected to the grid, but in a very different and less efficient way than homes that are powered by solar. The power grid is an electrical highway. It is composed of all the different power lines and collection towers that we see connecting our homes to large power plants. Most of these power plants are coal-powered, though some in Nevada rely on natural gas.

Most people that get solar end up staying connected to the power generated by their local power company. Although this is not the best solution, it is the cheapest.

When you stay connected to the grid you are given the ability to draw power from your power company during the night or when inclement weather occurs. Most solar systems take this into account and quote a solar array that will produce enough energy during the day throughout the year to offset the cost of using coal power.

How Do Solar Panels Work in Relation to the Broader Residential Solar Process?

Each home has different energy needs. One family may have large energy consumption items such as a hot tub or an aquarium while another family in the same size home is hardly home to turn the lights on.

It is for this reason that solar estimates are based off of how much energy your home uses. Your energy consumption is labeled as usage on your power bill. Getting a system that is sized correctly for your energy needs is vital to a good solar experience.

Now that the direct current from your solar panels have been converted into alternating current you can use this to power your home. When it comes to powering your home the reality is that most of the time we use more energy at night when the sun isn’t out.

Without the sun your panels will not be able to absorb UV radiation and your system will not have anything to convert into energy.  Thankfully there are a couple of solutions to this problem, such as battery backup.

Each home has different energy needs. One family may have large energy consumption items such as a hot tub or an aquarium while another family in the same size home is hardly home to turn the lights on.

It is for this reason that solar estimates are based off of how much energy your home uses. Your energy consumption is labeled as usage on your power bill. Getting a system that is sized correctly for your energy needs is vital to a good solar experience.

Solar Panels System: Size, Power, and Production Measurements

Getting a system that is properly sized for your home has a couple of factors that go into it. Below we have gone through what is needed to configure your system.

Sizing the Residential Solar System

The size of a solar array or set of modules/panels for residential rooftop solar is usually measured in terms of watts. Every system is sized based on historical trends and how much sunlight panels receive in an average year.

It’s a 25-year investment because it disperses evenly over that time frame. There are too many variables to say shorter. System sizing is important to solar energy generation. That’s why we don’t recommend DIY solar projects. Additionally, many solar panel installers rely on SAM (Solar System Advisory Model) software to gauge and size a residential solar array for each home.

System efficiency – All electrical equipment gets less efficient the older it gets, no matter what claims anybody makes. Be leery of solar contractors or installers who promise equipment functionality that never deteriorates, as it will always deteriorate at least slightly.

Production Metrics and Important Units of Measurement for Solar Panels

There are several different terms that are commonly thrown around when talking about solar panels. The most common of which is kWh, voltage, amperage, wattage, net metering and peak solar production hours.

If you have some electrical background then most of these terms are basic knowledge. Not everyone works with electricity though so we are going to give an underlying understanding of these terms.

Kilowatt Hours

(kilowatts)(number of hours running) = Kilowatt Hours

Commonly expressed as KWH or kWh, kilowatt-hours are a frequent unit of measurement when it comes to solar panels. Although the term may seem confusing, it is only a verbal expression of a simple multiplication problem.

An example of this type of equation in action would be finding the kilowatt-hours for a 7,000-watt rooftop solar array that is producing solar energy for 8 hours on one particular day. After doing the multiplication problem above we find that the total number of kilowatt-hours (kWh) is 56,000.


Voltage can be thought of as the pressure of an electrical current. Energy provides voltage, which is necessary for the flow of an electrical current. Often notated as V or U, the voltage between two discrete points is equivalent to the work of charge units offsetting an electric field.


Amperage is the strength of an electrical current measured in amperes. Essentially, it is the amount of electrical current flowing through a conduit or system. The product of voltage and amperage is the amount of wattage. Just to give you an understanding of how strong units of amperage are, it takes only .75 amps to stop someone’s heart.


(voltage)(amperage) = wattage.

For solar installation technicians to do their jobs correctly, they must be able to configure the system to maximize wattage, which is the total amount of electricity conducted. Each panel on a solar-powered home typically has 250 to 310 watts, which is measured in power.

Peak Solar Production Hours

Unfortunately, not every hour of the day throughout the year provides that same amount of ultraviolet radiation. There are between 3 to 5 peak hours per day in the united states.

The peak production hours for your area has to do with the intensity of light that is produced during the day. These hours are when the sun is highest in the sky. To find what your peak hours are for your home you can use an isolation map.

Most electronics perform better in cool environments and solar panels are not an exception to the rule. Your panels will produce more efficiently on a clear cool day then they will on a cloudless hot one. But, because days are longer it is typical to have more production hours during the summer and the closer you are to the equator.

Off-grid vs. On-grid Solar

When considering the financing of your solar system you will want to know if an off-grid or an on-grid solar array is going to be a better option for you. It should be noted that getting an off-grid system is more expensive than an on-grid.

The price for an off grid system is more expensive because the price of battery backup technology has yet to go down. As time goes on more battery backup options will be available which will make going off grid a viable option for more people.

This being said we have installed a few off-grid homes over the past 9 years and would be more than willing to work with you if you decide that this is the better option. If your home is remote then getting battery backup may be your best option.

Will my solar panels work in the wintertime or with snow?

In the winter snow is a concern for many. If you get snow on your panels, the panels won’t work. Panels heat up and melt snow, but it doesn’t melt in a day.

UV radiation heats up panels and melts snow faster than a traditional roof. This being said if you have a large build up of snow there is no way for the panel to get heated by the ultraviolet rays from the sun.

If you have a lot of snow on your roof you have a couple of options. If you don’t have a way to get to your panels then you will have to rely on the sun to slowly melt the snow. If it isn’t too cold outside, you can gently spray the panels off and the snow will melt off.

The last option is to purchase a roof rake. If you get a roof rake, making sure that it has rollers, will protect your roof and panels from possible damage.

If you decide to use a roof rake, be careful. The possibility of snow falling on you is very high. You will want to make sure that you are as far away from where you’re pulling the snow as possible.

Environmental Considerations on How Solar Panels Work

Many solar companies are at the forefront of innovation and actively trying to improve the sustainability of the American west with solar solutions, should not just think about the environmental viability of the panels themselves, but also the green manufacturing and production process of the panels themselves. If companies do not care about these things, the environmental bullet point on every piece of the company’s marketing collateral is just false advertising. So, here are some things to consider when trying to find an environmentally conscious solar panel provider.

Which Solar Panel Manufacturers Can I trust to Keep Solar Energy Green?

There are tons of panel manufacturers that are popping up internationally. With the new boom in solar production has come a need to make sure the process is as clean as possible.

Cheap panels have been produced in order to compete, but these panels have been coming at a high cost. Air and land quality around solar power plants taking short cuts has been compromised to provide a cheaper product.

Using solar panels is clean and helps our air stay clear, but the production of these solar panels sometimes prohibits this from happening. If clean air is one of your motivators to getting solar, we highly recommend looking at the panel manufacturer.

If you look at the manufacturer’s solar scorecard from the Silicon Valley Toxics Coalition, you will have a better idea of not only the quality of product, but also the integrity of the company in its environmental production processes.

Is There Waste from Solar Panel Production?

Although cleaner than coal and natural gas the process for producing panels is not a clean one. Chemicals such as cadmium telluride, copper indium selenide, cadmium gallium( ii) selenide, copper indium gallium (di) selenide, hexafluoroethane lead, polyvinyl fluoride, crystalline silicon and silicon tetrachloride all take part at some point in the process.

Toxic sludge is created when these metals and toxins are removed from the water used to manufacture panels. If the manufacturer doesn’t have waste treatment equipment this waste is transported to an approved dump.

The good news is that light has been shined on this topic and as a result, more consideration is being given to waste management. Going with a manufacturer that has a high solar scorecard means you are going with a company that is being responsible with the waste produced and trying to produce as little waste as possible.

A study done by FLASH and funded by Technology Foundation STW found that in order to avoid an energy sink we need to make sure that we can recoup energy waste faster than we are creating it. In their results in this study they made this statement:

“Energy pay-back times drop from around 5 years in 1992 to around just under 1 year for poly-Si and just over 1 year for mono-Si PV systems currently.”

This means that although there is waste involved in the process of creating panels it is improving. We have to take into account that solar has only been here since the 70s and therefore is still relatively new. The fact that we can recoup waste output within a year of solar array use is extremely impressive.

Recycling Solar Panels

Because solar panels last at least 25 years most of the panels that have been produced haven’t gotten to the point where they need to be recycled, but they will. As a result, efforts have been made so that these panels can be recycled correctly.

If we don’t do our part to make sure that our panels are disposed of properly toxic substances from these panels could prove to be a huge hindrance to renewable energy’s mission. Right now Europe is taking the lead but, as time goes on recycling panels will be mainstream.

As of right now, technologies have been created to recycle 96 percent of PV waste. This is just the beginning of where solar recycling is headed.

Solar Energy Facts, FAQs & Information

What Do Solar Power Plants Do?

When it comes to how solar energy is generated from the sun, there’s more to generating solar electricity than at-home solar systems entail, and that’s where solar power plants come in. Although Go Solar Group does not specialize in any services or products tailored to solar power plants, we know a lot about them and where they fit in the solar energy landscape. Solar power plants can generally be divided into two distinct categories: photovoltaic plants and solar thermal power plants.

The latter of these two makes electricity by concentrating the photoelectric energy of the sun, and the prior of these two kinds of power plants is the kind homeowners put on their rooftops every day, and in increasingly large numbers – residential solar.

This means that every residence with rooftop solar is technically a power plant, which is a pretty cool concept to think about!

How Does Solar Power Work at Night?

Solar panels use the light waves from ultraviolet rays that the sun produces to excite the electrons in the cells of a solar panel and create a current. At night, however, these specific light wavelengths aren’t there to get the electrons moving and create a charge.

Moon Power and Lunar Panels: Fact or Fiction?

The moon reflects the light that comes from the sun to the earth. These wavelengths are longer than the ultraviolet rays that are used by the sun’s direct light. Longer wavelengths do not provide enough electron movement for the panels to power anything.

Unfortunately, panels have not as of yet been created to effectively use light reflected from the moon or produced by the stars light-years away. For now, moon/lunar powered panels are still science fiction.

Salt of The Earth: Is this the key to Unlock Solar Nightlife?

In 2009, articles started to come out with a new plausible solution to using solar power at night. Scientists found that because salt has a high melting temperature, it was perfect for storing heat.

The Crescent Dunes Solar Energy Project in Nevada uses molten salt heated by the sun during the day. This superheated salt is then used to power a turbine at night or when the weather is not conducive to solar power.

This idea is wonderful and is proving to be a much cheaper option than the lithium-ion batteries that are being used to store solar power. The problem is that this process requires a lot of space and the technology hasn’t been converted to a usable format for homeowners. Only time will tell if there is relevant progress to be made here.

Financial Considerations: How the Way Your Solar Panels Work Impacts the Rate of Return

When it comes to making large additions to your home all financial aspects need to be considered. Getting solar to replace your current power provider for the next 25 plus years is a large addition.

People need to know what to expect so that they know when they have a good deal. Using a solar savings calculator will help you get started. Here are a couple of other things to keep in mind while considering finances.

Know that the Biggest Solar Installers Usually Aren’t the Best Options

The National Renewable Energy Laboratory did a study on the relationship between installer pricing and firm size in April of 2017. It was found that large firms are more likely to aline prices with their brand’s reputation. A smaller firm, on the other hand, is more likely to cite fair prices for the customer.

This equates to large installers being about $2,000 to $5,000 more expensive than a smaller one. This being said this doesn’t mean you should completely write them off as an option. Just make sure you are looking at all the aspects of the product you are purchasing before deciding to go with the name brand that everyone knows and uses.

Solar Production and Service Warranties: An Important Consideration for Homeowners

Warranties vary depending on the manufacture of the product. There are a couple of different types of warranties that typically come with a solar installation.

A solar installation normally has a 10-year warranty. This warranty covers certain materials that are damaged within the first 10 years of use.

Production warranties typically last for about 25 years. These warranties guarantee a certain percentage of product production. Most guarantee that your panels will still produce between 80% to 90% of their original capacity in the first 25 years of use.

Making sure that your manufacturer has good warranties will ensure that your investment will last in the long run. Go Solar Group uses Axitec panels these panels have a 15-year product warranty and a 25-year production warranty of 85%.

Advantages and Disadvantages of Solar Power for Homeowners

No matter what you are looking into there will be some pros and cons to it. For all of the major decisions, Benjamin Franklin had to make he would put together a pros and cons list. His list helped him to properly weigh what was the best decision.  We have put together some of the pros and cons that we have seen in solar power for you to analyze for yourself.
