"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."

"I had Soltari install my solar panels and I’m really happy with how everything turned out. I was a little nervous going into it since I didn’t know much about the process, but they made it super easy to understand and handled everything. The team was professional, respectful, and just really easy to work with. They showed up when they said they would and made sure everything was done right. Now that it’s all up and running, I’m honestly so glad I decided to go with them. I’d definitely recommend them to anyone looking into solar 😊"

"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."

Solar Panels FAQs, answered by experts

Solar panels can protect your roof from hail, as they can withstand hail up to 1 inch in diameter that falls up to 50 mph. Your solar panels may experience damage if the hailstones are bigger and travel faster. Your roof can still suffer hail damage, and it’s essential to look for signs and repair issues right away. Roof damage can lead to leaks and water damage inside your home.

Depending on the climate in your area, the best time to install solar panels is either winter or early spring. Summer is a fine time to install panels, too, but it tends to be the busy season, so prices may be higher and companies may have packed schedules. The installation process can take more time than expected between getting permits and finalizing a design, so start as soon as you can.

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.

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.

In most cases, solar panels are covered by homeowners insurance because they are considered a permanently attached part of the home, and you may not need additional coverage. However, it is essential to read the fine print of your specific policy to understand the extent of the coverage, as some policies might only cover certain types of damage, such as hail. Always check with your insurance provider before installing solar panels to ensure your policy provides adequate coverage for your investment.
