"I originally found out about this company, SONERGY USA, as I had to have the inverters replaced for an existing solar panel setup I had. The folks I interacted with were amazing and extremely professional. They were able to take care of the repairs right away, but more importantly they fixed some items the original solar panel installer did not do properly. I was so impressed by the work SONERGY USA did with the repairs that I eventually moved forward to get additional panels installed and even a battery installed. Again SONERGY USA did not disappoint. Everything was professional and done properly. Most of all the communication with the team was amazing where I did not have to babysit them or waste time off from work in order to get the work completed. SONERGY USA stuck to the timeline as well. which I greatly appreciated."

Solar Panels questions, 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.

Homeowners replace their solar panels after 25 years. That said, you don’t necessarily need to replace them at the 25-year mark. You’ll notice a declining ability to produce electricity over time. Most homeowners spring for a replacement when they notice their energy bills creeping up to regular levels or when solar panel repairs are extensive, frequent, and no longer economical.

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.

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.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.
