"I am so glad that I found Malone solar. I needed someone to remove my solar panels and then reinstall them when I got a new roof. Their price was reasonable. They communicated well and did not charge me until the job was done. Their pricing also included some materials that needed replacing. Their workers were kind and respectful of my property and cleaned up when they were done. I don’t usually leave recommendations but MLine earned my respect. If I have any solar needs in the future they are the solar service I will be calling. Thank you MLine! You are the kind of company I want to do business with."

"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."

Credit card accepted

"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"

Solar Panels FAQs, answered by experts

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.

Yes, installing solar panels or a solar roof can increase your home's value by approximately 4% to 6%. For a home with a median value of $429,000, this could translate to an increase of around $17,000. A well-maintained solar installation appeals to environmentally-conscious buyers and those looking to lower their utility bills, often helping homes sell faster and at a premium in areas with high electricity rates. However, the exact increase in value depends on factors like the local real estate market, energy costs, and available solar incentives. It's also important that the system is correctly installed and maintained; an older or poorly maintained system may not add significant value, particularly if it's near the end of its lifespan. Other solar features, like panels on a shed, can also boost your home's value.

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.

Installing solar panels involves drilling small holes in your roof to secure the solar panel mounting brackets. These brackets hold the solar panels in place and must withstand strong weather conditions so they’re secured into your roof. However, holes and screws are sealed to prevent leaking and further damage.
