"Smart Wave Solar did a superb job of every thing from start to finish with installing my solar panels. After comparing them to many other companies they were by far the least expensive for top quality panels. Even with Covid stuff going on that caused some pinch points they manged to get things done in a reasonable time frame. I am happy so far with my purchase, the service and the over all results of their work. Would highly recommend them to anyone looking to get into solar."

"The tech showed up a little early which I appreciated; nothing worse than being late for an appointment. He quickly diagnosed the issue with our solar system and is working to get a new inverter under warranty from the manufacturer. He also installed a critter guard to keep the birds from nesting under our panels."

"The solar electric system is now installed and functional 5.5 KW Grid tie system. Standard Relewable sub-contracted much of the work, and I had to deal with several Standard Renewable people over the course of the project. I paid in two payments by credit card. They were very slow to make arrengements to take the second payment. There were several times when it was difficult to get response by email. I emailed several times to make the final payment, and could not get them to do so. The conduit in the Attic is run so that it crosses open space at head knocking height. Over all the system is installed and working, but lacks fine touches"

"Please Read!!! After looking for over 2 months I came across Golden Solar. At first I was impressed with the communication, happy with the reviews and the agreed price till I sign in a contract then all communication stopped. The second day they came out and surveyed the property and I thought that this is going to move quickly and I"ll be generating my own power soon. Well this was the end. 1 month later no call or no updates and no return calls. I called and talked to the owner and ask what is going on!!! He didn't have a answer for me. After 2 months again no calls no updates and no return calls. I called and talked to the Sales person and ask what is going on!!! He also didn't have any idea but said he was going to the office and have a meeting with the owner and on Monday will have a firm installation date. Monday came and again NO CALLS so on Tuesday I called and talked to the owner and he said that he could not do the job because of my Concrete Tile Roof (what!!!). If concrete tiles are a problem this should have been told to me when they came out and surveyed my property, the 2nd day. This company should have told me from day 1 that we cannot do this job Instead they wasted over 2 months of my time for nothing. Now I have to start over from square 1 looking for Solar. This is the worst customer service I have ever had dealing with any company. I tried to give this company 1/2 stars but this website wouldn't publish it."

Solar Panels FAQs, answered by experts

You can install solar panels on a flat or pitched roof, but keep in mind that they will need to rest at a 30- to 50-degree tilt for optimal sun absorption. It costs more to install solar panels on a flat roof because you will need to install a framing system and likely hire a structural engineer. If your roof has a pitch of more than 40 degrees, it may not be a good candidate for solar panels.

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.

Solar panels can pay for themselves in five to 15 years, depending on the cost of your system, how much energy it generates, whether you qualify for incentives or power buybacks, and the price of energy in your area. Solar panels pay for themselves over time as they lower electricity bills, so it will take time to recoup your initial investment. However, the longer you have your system, the more money you can save and earn.

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.

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.
