"Well we were going to do a ground mount using re-purposed
metal, but there was not enough of it. So Renewable Engineered Systems designed
a system for the roof of the house. We Worked with Brian Brown who helped us
decide what to use.   The solar panel
system is very neat. Get to watch my power everyday.

"The last was a rental company that we have and we used them for an air conditioning and heating system. It was Bototach Mechanical. It’s been a good program for us. They’re very responsive. I don’t know what the thought process was. My husband said, well let’s try these guys and so we did. We have an older home and it’s proved to be a very good deal. The quality has been pretty good, so I would give them an A for the quality. I will give you one helpful hint though. If the company decides they want to replace an appliance, you need to call them and negotiate with them because you can upgrade, but you need to talk to them in person not just do it over the internet."

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.

The average homeowner needs around 22 solar panels, but the exact number depends on your monthly energy consumption. Your solar professional should size your array to offset your consumption, meaning you’ll need fewer panels if you use below-average amounts of electricity, or more than 22 if you use above-average amounts of electricity. The number of panels also depends on the output of each panel. The average is around 400 watts, but you might need more panels if you install less capable equipment. Since there are so many variables, you should have a professional size your system.

The best way to know if your roof can support solar panels is to hire a structural engineer. They’ll look at your roof and approve the design of your solar panel system or suggest changes. The best roofing for solar panels is made from strong materials like asphalt shingles and metal, but tile and gravel will work. Softer materials like thatch or temporary structures are not a good fit.

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.

Solar shingles and solar panels are not the same. While solar shingles use the same technology as traditional solar panels, they integrate with your existing roof. That means they are used to build your roof instead of simply resting on top of it. When comparing solar shingles and solar panels, it's helpful to know that solar shingles are more aesthetically pleasing than solar roof panels. They also do better in harsh weather due to limited uplift from strong winds.
