"Got new hot water heater, but they said they were unable to assess the solar panel or install a new solar system.Strange, since they advertise solar hot water systems. I now do not have solar powered hot water heater, but have a regular electric one."

"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!"

"Jeff was great to work with. He took the extra time to discuss questions we had while making sure our solar project was managed seamlessly from start to finish. Everything was planned for and taken care of, down to the small details where his crew took the time to color match the new electrical conduit on the roof as well as on the exterior wall of the house. The entire process was completed in a timely matter, from the initial planning stages, through permits, installation and inspections."

"Unfortunately my husband s company is moving us to the midwest. Even though we had a signed contract with Rick and Teresa at Sunriver Solar, they we very understanding and basically told us not to worry about it and to enjoy our next adventure. They even asked if they could help us with any of the moving stuff!!! They are a delight to work with, they do everything, they kept us up to date on what was going on, and, even though we could not work with them, we would highly recommend them. You really cannot go wrong with Sunriver Solar."

"I have to have my roof replaced of the 3 companies that came out Spartan was the only one who addressed the leak I was concerned about. The other companies were going to charge me a bunch of money and let it still leak. They were not going to address it until it was an issue and tell me it was not covered. Spartan was top notch start to finish. The guys working on the house were awesome as well as every one I worked with. I would highly recommend them."

Solar Panels FAQs, answered by experts

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.

The actual time it takes to construct the solar farm is relatively short, taking between 2 and 4 months on average. That timeline is dependent on site conditions, crew size, and the overall size of the solar farm.

However, the time it takes to get the ball rolling is significantly longer, ranging from 3 to 5 years. With a project of this scale, you’ll need to obtain all of the proper permits and approvals to start breaking ground, and depending on your location, that could be an extended process.

Rooftop solar panels supply energy to a single household, where a solar farm can power multiple homes at once with clean energy. Residential rooftop solar panels cost more per watt with a lower project total, and those panels only service the residence they are installed on (in most circumstances). With a solar farm, multiple households can buy into the project and share the overall cost.

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.

  • Installing a new electrical meter box

  • Replacing your meter base

  • Replacing your service entrance cable 

The cost to install or upgrade an electrical meter box ranges from $100 to $650, including $50 to $250 for the unit. The meter base passes the power from your electric company to your panel. The cost to replace a meter base is roughly $50 to $250. 

Service entrance cables are electrical cables with multiple wires, bringing power from electrical companies to residential buildings. The cost to replace a service entrance cable ranges roughly from $1,000 to $1,500.
