"After having a nightmare working with two smaller companies, I decided to go to NRG Clean Power for my solar needs. I?m understating when I say the experience was like night and day: efficiency, communication, and progress the whole way forward. Before I knew it, my installation was complete and my solar equipment was operational. I want to thank Miles in particular for his hard work and constantly being available to answer my questions. Everyone does their job right at this company. Wonderful experience and I?m saving money while helping the environment!"

"i could not be happier with OC Solar, they deserve all of the hype! i have worked with vinnie and the oc solar team for over 5 years and done many projects with their team. they are always on time, priced well, easy to work with, and the communication is excellent. itâ s hard to find good contractors, so when you find one, you have to tell people, and OC Solar is worth putting my name on the line for. we have had them install Tesla power walls for us, specifically the tesla power wall 3. they have installed panasonic and q cell panels for us and the installation quality is top of the line. highly recommend, 10/10. choose ur installer wisely, los angeles is not easy to work with, so i recommend a proven company like OC Solar"

"Workers came prepared with gloves and face masks. Very knowledgeable and quick workers. Fixed both solar and hot water heaters and pressure reducing valve. Pablo even went on roof to inspect my panels and noted missing flashing over roof penetration, assisting me to visually inspect the issue. Would highly recommend."

"We’ve been very happy customers of Stellar Solar for years, from our original solar panels to their ongoing support. Earlier this year, they proactively contacted us because they noticed we might be eligible for a home battery system rebate. They handled all of the tedious work, navigating the confusing paperwork and submitting everything seamlessly. If not for their help, we never would have been approved for a battery system through SGIP. They truly made the whole process effortless. A huge thanks to Joseph and Robert for a great installation job—especially for taking the extra effort to run the wiring so cleanly through the attic!"

Solar Panels FAQs, answered by experts

Yes, going solar really saves money. In fact, according to some calculations, the average homeowner who switches from electric to solar power will save almost $2,000 a year on energy costs. While buying solar panels and switching to solar can be costly up front, the savings add up over time. If you can sell back extra energy or take advantage of tax incentives, your savings can be even higher.

In most cases, yes, solar panels are well worth the investment. Going solar with your home’s energy is expensive, but, in most states, the panels will pay for themselves by reducing your electric bills. Solar panels don’t produce greenhouse gasses or other pollutants, meaning you can feel good about using this renewable energy source to power your home. Plus, installing solar panels can boost your home value, helping your profit off your next home sale.

Although solar panels harness the sun's power, they come at an environmental cost. The manufacturing process requires large amounts of water and involves hazardous materials like cadmium, silicon, and gallium arsenide. These materials don’t pose safety hazards while the panels are in use but can pose a problem when left in landfills. Over time, hazardous materials can leach into the environment. This is why recycling solar panels whenever possible is better than taking them to landfills.

Yes, you have to get on the roof to cut a hole for solar tubing. It's not possible to complete the job from inside your house by simply cutting through the ceiling. So if you want to go the DIY route, remember to use safe ladder practices. If you’re not comfortable climbing on your roof to install solar tubes, hire a pro who has the tools and expertise to do the job safely.

There are a few great questions to ask a solar contractor or inspector when you speak to them. You’ll probably want to find out about the energy yield and efficiency of your array, ensuring the actual output matches the amount you calculated when installing the array in the first place. It’s also a good idea to find out about any damage or wear and tear on the array and to inquire about how soon you need to make repairs or replacements to essential components.
