"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."

"His name is Andrew Johnson. He is going to be doing our carport next. He does all of our electrical but he also does incredible solar. It was around $17,000 for the solar. We have a big house. You can't beat his prices. He doesn't have a huge company. His guys are great. He shows up when he says. He does meticulous work. The city's came out and told him right in front us that he did better than perfect. He lives in our neighborhood. He told him to get on Angie's List"

"Very thorough and detailed explanation for any questions you may have. They are a great family run company, not one of those big companies that are trying to rush the entire process and installation, just to get to the next job. Recommend this company for anyone looking to go Solar to get our of those crazy ever increasing electric costs."

Solar Panels questions, answered by experts

While you can minimally overshoot the number of solar panels you need for your home, it's not smart to go too far. Not only is the extra cost unnecessary, but your state may put caps on how much energy your home can produce and send back to the grid. It is always best to work with a solar energy professional to determine the best system size for you.

Solar panels should get at least four to six hours of direct sunlight daily. It’s even better if sunlight reaches panels between the peak hours of 10 a.m. and 3 p.m. This is enough to power a home, depending on your solar system’s size and energy needs. Remember that panels will generate some power under cloudy skies or in the shade, and many systems compensate for lower sun exposure by drawing energy from the grid or battery storage.

You shouldn’t hook up a solar panel directly to a battery. That can damage the solar battery and your appliances over time. Instead, install a charge controller between your solar panel and solar battery. Charge controllers regulate voltage, prevent overcharging, and minimize the amount of electrical current to protect your battery from voltage spikes.

No, you cannot turn on a new solar system before inspection. The inspector checks that the system is correctly connected to the grid and that safety components and features are in place. This process prevents problems on the electrical grid and offers protection against fire in your home. 

Your local utility company may also require inspection documentation before you can connect to the grid. An inspection can ensure solar power efficiency and determine how you might increase it.

The average cost to install solar panels is around $27,000, with most homeowners paying between $4,500 and $54,000. These prices don’t consider the federal investment tax credit (ITC), which can reduce costs by up to 30%. The final price depends on several factors, including the size of the system needed to offset your energy consumption, the amount of sunlight your home receives, your geographical location, the type and brand of panels, labor costs, and any add-on products like solar batteries or electric vehicle (EV) chargers. It is recommended to get price quotes from at least three solar companies in your area to find the best deal.
