"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

Yes, it is possible to install solar panels on a tar and gravel roof, but it is not the ideal roofing material for a solar installation. The process requires roof penetrations to install the solar racking system. While installers will seal these penetrations, they still increase the risk of leaks. This risk is higher on tar and gravel roofs, which are often flat. Flat roofs are more prone to leaks than sloped roofs because they can pool water during heavy rain and hold snow for longer periods, exposing the roof to more moisture.

It’s possible that installing solar panels can lead to mold on the roof. The panels themselves are not the issue. Problems caused by improper installation—such as roof leaks and mounts that aren’t sealed properly—can cause mold. Another potential cause of mold is debris accumulation under panels, which can trap moisture. If you live somewhere with extreme snow, rain, or hail, your home could be more prone to mold.

While solar panels can be a great investment, they aren’t ideal for every roof. For example, some roofs, especially older or structurally weak ones, may struggle to support the added weight, leading to potential damage. Roofs with complex designs, obstructions, or limited sunlight exposure might not provide optimal conditions for solar energy production. Consider these downsides when determining if solar panel installation costs are worth it.

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.

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.
