"Really appreciate Mahon (Mike and Robert) to come out the day after New Year's to assist us. Our basement bathroom drain line had clogged and I had spent most of NYE day trying to use a plunger and typical off-the-shelf remedies to fix. This service qualified as a emergency call due to the holiday (as these things happen). We were the 7th customer they were scheduled to see. Luckily, they were in the area for another emergency appointment and were able to assist us earlier than promised. They were extremely careful in lugging the 250lb auger through the house and did not damage anything. They had the drain open and flowing within 10 minutes. Mike and Robert were super easy to work with and very professional. Awesome service! KR"

"Many people, including me, are debating solar panels. That's a lot of money. But, solar power is the only free thing we can get besides gas and water. Thanks to Lumina Solar, the process was smooth and pleasant. I still remember the installment day. A group of young men showed up. They're working and chatting happily together. I was inside, but I could feel their energy. That's a sweet memory!"

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.

The time it takes to install solar panels depends on the number of panels and the size of your home, but installation takes between two and three days of work. While most contractors can install the panels over the course of a couple of days, switching to solar energy can take two to three months in total. This includes the time it takes to design the system, procure the parts, obtain the permits, install the panels, connect to the main power grid, and get an inspection.

On average, a typical fridge uses 115 kWh per month. With eight hours of sunlight per day, a 100-watt solar panel can produce 30 kWh per month. This means you’ll need at least four dedicated panels to power the refrigerator with solar energy. Consult with a solar power specialist to get a more accurate estimate.

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.

Professionals use the same methods to install solar shingles that they do for asphalt shingles, so you’ll often see a similar installation timeline of one to two days. The amount of time required will depend on the size and slope of your roof and the number of shingles installed. Weather conditions can delay installation, as working on a roof is unsafe during high winds or heavy rain.
