"Ian and his crew were excellent! Very knowledgeable and professional. He told me more about my solar system than the company that installed it! They arrived and went right to work removing my solar panels, and once the needed work was done on my roof they came right back and reinstalled them! I would highly recommend them to anyone needing work with their solar system!"

"I contacted Solar Medix replace two DC string inverters on our 15 year old solar array. As it turned out, they were able to correct some wiring instead of replacing the inverters! Thank you for doing a fantastic job! They saved us a few thousand dollars! And I highly recommend them!"

"We have used Gene from Preferred Plumbing on several occasions. We had a water heater replaced and multiple faucets, hose bibs changed or repaired, and drain / sewer clogs. Gene was responsive, courteous, and explained the issue and required work clearly. The work was completed without issues and reasonably priced. I recommend Gene (Preferred Plumbing) for any plumbing issues / work."

Solar Panels questions, answered by experts

The morning sun can be better for solar panels because it’s often brighter and clearer than the afternoon sun. The brighter the sun, the more energy solar panels produce. The strongest rays occur during midday, which tends to be prime time for solar energy generation. Most homes get a mix of morning and afternoon sunlight.

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.

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.

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.

Yes, you should tell your home insurance company about your solar panels. Even if you believe they’re covered by your existing policy, installing a solar panel system is a significant change to your home. This can affect coverage and premiums. By discussing your new solar panel installation with your insurance provider, you can be sure you have enough coverage and that the policy completely covers the panels against damage.
