"I initially had reservations about the concept of installing solar panels, but I was keen on getting an estimate and seeking professional advice. That's when I met Arvin. He provided me with a comprehensive walkthrough, clearly outlining the advantages of having solar panels. The entire process was straightforward, with each step being well-explained, leaving no room for surprises or unexpected outcomes. Now, a little over 5 months since the installation, I'm enjoying the benefits as expected. I want to extend my gratitude to Arvin for his professionalism and responsiveness. He was always there to address any questions I had, both during and after the installation process. Thank you, Arvin!"

"I had an issue with our solar panel not producing any electricity so I called and left message for Garrett from Sunlux. Not only did he call me back the same day, but he basically diagnose the problem over the phone and sent someone from Sunlux to come to my house the next business day to confirm diagnosis that we had a bad inverter. A few hours later that day Garret called not only to schedule an install of the new inverter, but to my surprise he also said that because we were having problems with pigeons living under the solar panels that he would install critter guard to prevent the pigeons from going underneath the panels for no charge. I would highly recommend Sunlux for their professionalism as well as their great customer service."

"Yep, Indaspec is a five start company. They were responsive and professional. The system we got has boosted our 2003 system and cost 1/5th the price. It will pay itself off in 3 years, possibly less. They were efficient in the installation - took about 1.2 days. The connection between our system and the app on our phones is super easy and now my husband and I have been high- fiving each other once we find out how much the new system is producing. Get the solar, Guys! This company is a gem! The office manager is a sweetheart and the bidding process was easy. The installer was a man of few words for me (I didn't really know anything about the tech part), but took time to speak to my curious and informed contractor husband. He was patient and explained everything so that my husband felt satisfied that he was doing right by our beloved and somewhat coddled home."

"We are so excited that NRG helped us to install Solar Panels on our house in San Francisco! Their entire team was wonderful from their first presentation providing us with all the information to the completion of the installation. Their installation staff was wonderful and completed the project without a hitch. Nicole Greenwood our customer service rep kept us informed of each step along the way and made everything easy. We had gotten estimates from two other companies and are glad we went with NRG. No worries and a wonderful experience. We will recommend NRG without reservation. Thanks to your whole team! Marge B."

Solar Panels FAQs, answered by experts

The morning sun can be better for solar panels because it’s often brighter and clearer than the afternoon sun. The brighter the sun, the more energy solar panels produce. The strongest rays occur during midday, which tends to be prime time for solar energy generation. Most homes get a mix of morning and afternoon sunlight.

There are a few qualifying questions you should ask a local solar panel company before hiring them:

  • Will you handle permits for the installation?

  • Does your total price include the equipment and labor?

  • How long do you expect the installation process to take?

  • What kind of workmanship warranty do you include with your installations?

  • Who should I contact if I have a problem with my system after installation?

  • Do you install the panels or outsource the work to third parties?

  • Will you file for solar incentives for me?

DIY solar panel installations are hard to manage by yourself. You’ll likely need some help or prior experience to make the project worth the effort.

The best solar panels to withstand hail are those rated UL 61730. These solar panels are certified to withstand hailstones up to 3 inches in diameter and travel at speeds up to 88 mph. IP68 solar panels are the next most resilient solar panel. Solar panels without these ratings can handle hail up to 1 inch in diameter that travels up to 50 miles per hour. If you live in an area with frequent or severe hailstorms, purchasing UL 61730 solar panels is often worth the investment.

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.
