Solar FAQs
The questions we get asked most, answered plainly.
Not on the list?
Ask us. We would rather answer it now than have you find out later, and the consultation is free either way.

What is a Power Generation Guarantee?
Every contractor has to file a production forecast with the utility supplying your rebate. We guarantee that number. If your system does not produce the annual kWh logged on your rebate application over the three-year guarantee period, that is on us. Most warranties come from the equipment manufacturer and are set by industry standard, not by your contractor. This one is ours.
Does that mean you are guaranteeing the weather?
No. We are guaranteeing that the system was designed and installed properly and is performing properly. Your production forecast is based on government data covering decades of weather patterns, so it would take sustained, unusual weather to move it. If that happened, it would be taken into consideration.
What happens if my system underperforms?
We monitor your production and inspect the system periodically, watching for any drop. If there is a shortfall there is a reason for it, and it can be as simple as a blown fuse or as serious as a bad connection. The guarantee is what makes sure somebody goes and finds out.
How long is the installation warranty?
Ten years on our installation. The common figure around San Antonio is five, because five years is all CPS Energy requires. Your system should be working for decades, so ten years of coverage is a better place to start.
Do you do the electrical work yourselves?
Yes. Design, installation and the electrical work are all in-house, and we have a full-time master electrician on staff. We are a licensed electrical contractor and we carry workman's compensation insurance, which the State of Texas does not require us to carry.
What is a solar battery, and do I need one?
It is the solar version of a generator. It stores power while your panels are producing, and takes over when the grid goes down. It is worth having if a storm knocking out the grid would be a serious problem for you, or if you want to use your own stored power in the evening rather than buying it back.
Will solar work if my roof is the wrong shape or too old?
Sometimes the roof is not the right place for panels, and that is what ground mounts are for. Shading and architecture can also make a property a poor candidate. We will tell you if that is the case, and we will tell you before you have spent anything.
Can you handle my HOA?
Yes, and we routinely do. Texas law restricts an HOA's ability to refuse a roof-mounted solar system, and the submittal is one of the approvals we prepare and file for you along with the utility rebate application, the city permit and the inspection.
Is financing available?
Yes. There are $0 down options, and we work with long-term and short-term plans through credit unions and banks, plus a one-year same-as-cash option in-house. The point of financing here is to let the system pay for itself while you own it.
How does solar affect what I pay CPS Energy?
A grid-tied system feeds your home first and sends the surplus to the grid, so you save twice: on the power you no longer buy, and on what the utility credits you for what you send back. What that adds up to depends on your usage and your system, which is what the free assessment is for.
Start saving, and lock in your utility rate for the next 25 years.
A free, no-obligation consultation and energy assessment. You get the production forecast, the cost, the value of the power and the break-even, before you commit to anything. $0 down financing is available.
