Frequently Asked Questions

  How do I know if solar will work for me?

  An expert in SunPower® solar panels will walk you through whether your home is a good fit for solar.  You have to be a single-family home owner with a roof facing south or southwest that has good sun exposure, without many trees or other obstacles that might block the sun’s energy. They’ll also look at things like your household energy usage and roof space to determine the right system for you.

  How much does it cost?  Can I afford it? 

  The price can vary since each system is designed for a particular roof and customer.  With financing options available, qualified customers can go solar for as little as zero down* and low monthly payments, subject to approved credit.  Plus, it’s one of the few home improvements that may increase the value** of your home and dramatically reduce your electricity costs at the same time.  Your free quote will include all of the pricing and financing details to help you understand which option is the best for you.

  How do I get a quote, and do I have to pay for one? 

  It’s easy. For more information or a quote, fill out this request form. It’s free, and there’s no obligation.

  How much will I save? 

  Your solar savings will depend on several factors, including the size of your solar panel system, the angle and shading of your roof, and how much you use & spend on electricity. Your quote will include your estimated savings, taking all of these factors into account. 

  What happens after I sign up?  

  The process has three simple steps that we manage for you, end to end.  First is the free consultation.  We’ll walk you through the proposal and various aspects of your house to help you understand how solar could work for your home. Next: installation, which will take about a day once all the paperwork and permitting’s done. All of it’s taken care of by your SunPower certified solar installation contractor.  Finally comes inspection and activation – and you’ll be making your own solar energy! 

  How do solar panels work?

  Your SunPower® system turns on and off automatically. Cells in each solar panel convert sunlight into electricity that’s delivered to your home’s main electrical service panel.

  How much energy do solar panels produce?

  It depends on the roof and sunlight conditions at your home, but with adequate south/southwestern sun exposure the typical 5.5 kilowatt rooftop panel system in Texas will produce about 8,000 kilowatt hours in a year. (Source: PVWatts calculator)

  Do you purchase my excess solar power?  How does that work?   

  Yes. Sometimes your panels produce more electricity than your home uses at a given time. That surplus energy goes back onto the electricity grid. Your meter tracks it, and at the end of the month, once you’ve enrolled on one of our TXU Energy Renewable Buyback plans, we give you a bill credit for the excess energy.  We’re one of the few electricity providers that purchases excess solar power in Texas.

    Can I go “off the grid” when I get solar panels?

In Texas, most of us use a lot of electricity to keep our homes cool and comfortable much of the year, including at night.  You need another source of power after the sun goes down and your system stops producing electricity. To go off the grid you’d need a large battery backup system that you could charge up during the day, which is very expensive with today’s technology.
