How Powerwall Helps Solar Homes in San Antonio
When Go Solar Group first started installing solar, they realized something was missing. People who got solar weren’t being protected against blackouts.
Many think that they have nothing to worry about when they install solar. The assumption that solar will be there in a blackout is only true when the customer has the right system installed.
Now that Go Solar Group has become a San Antonio solar company, San Antonians can have a system that meets their backup needs.
Residential Solar During Texas Power Outages
Most people don’t realize that their system won’t work in a power outage. Solar arrays connected to the grid need a solar backup option to function during a power outage because electrical standards require solar panels to be shut off during an outage.
Why Solar Arrays Turn Off During Outages
The reason that solar arrays turn off in a power outage is simple — safety. The National Electrical Code requires photovoltaic systems to have a disconnect switch.
Disconnects will interrupt the current coming from the solar panels. When a current gets interrupted, it turns the power off. Disconnects make sure that no one will get electrocuted while fixing grid issues.
The problem is that disconnects disrupt all current coming from the solar panels. This electrical requirement for solar means that, although the sun may be out, the home still won’t have power.
Solar Backup’s Solution To Power Outages
Go Solar Group saw this issue and, as a result, provides battery backup solutions for all its customers. With battery backup, homeowners can access their solar power whenever they want.
Battery Backup in San Antonio
Back up is not a new concept. The problem is the only backup option people are aware of is home batteries.
Although home batteries are currently the best option, they aren’t the only choice. Depending on the customer’s situation, home batteries may not be an ideal option either.
Battery Backup: An Energy Storage Option
Battery backup is an energy storage option often used for residential solar. With battery backup, homeowners can charge a battery with their excess solar power. If a homeowner has enough home batteries, they can power the home when the sun is down.
Go Solar Group’s Battery Backup Options for Texas Residents
Go Solar Group realizes that each home is unique, and not everyone is a good fit for home batteries, which is why we have different levels of battery backup for our customers.
Portable Backup Solar Generator
Go Solar Group sells portable battery backup from Goal Zero in addition to Tesla’s Powerwall home battery. We offer two smaller battery backup options that help customers with smaller energy needs stay up and running during an outage.
In both of these options, customers have a choice between two different battery sizes. The Yeti 1400 will produce up to 1428 watts. The Yeti 3000 produces up to 3075 watts in a charge.
Portable generators weigh about 40 lbs. If customers need power brought to them, it is a great way to do it. The Yeti has several different ports so they can connect to several devices with ease.
Adding Battery Extensions To Your Battery Backup
If 3,000 watts of power isn’t enough, but a Powerwall is too much, there is another option. Customers can add Goal Zero Tanks to their Yeti.
The tank is a lead-acid backup battery that can connect to the Yeti. Each tank adds 1,250 watts of power.
Battery Backup for Your Home: Tesla Powerwall
Go Solar Group is also a certified Tesla installer. The Tesla Powerwall can power an entire home. The Powerwall spec sheet states that the Powerwall weighs 276 lbs and can be mounted on the wall or the floor.
Each battery can power up to 14,000 watts in one charge. However, if the Powerwall has continued use, it will power up to 5,000 watts between charges.
How many Powerwalls are needed depends on the power needs of the home and the priorities of the homeowner. Tesla recommends homeowners get two Powerwalls if they use 30 kWh per day on average and are planning on continuous use.
30 kWh may seem small, but it is equivalent to 30,000 watts. Homeowners will need to look at their monthly usage on their power bills to determine how much power they regularly use.
We can help you reach your backup goals. After filling out our solar panels for homes in the San Antonio area form, we will set up an in-person appointment. We can then help them find a battery backup solution that fits their needs.
