"I initially had reservations about the concept of installing solar panels, but I was keen on getting an estimate and seeking professional advice. That's when I met Arvin. He provided me with a comprehensive walkthrough, clearly outlining the advantages of having solar panels. The entire process was straightforward, with each step being well-explained, leaving no room for surprises or unexpected outcomes. Now, a little over 5 months since the installation, I'm enjoying the benefits just as he promised. I want to extend my gratitude to Arvin for his professionalism and responsiveness. He was always there to address any questions I had, both during and after the installation process. Thank you, Arvin!"

"When I moved into a new house in Maryland I was set on getting a solar system installed. After reviewing several proposals from competing companies I signed on with Nova Solar. From the proposal to the installation to the start-up of the system Nova Solar's attention to detail was none I have ever experienced working with subcontractors on my house. Their attention to detail was extraordinary. All of my inquiries and questions on the system were answered thoroughly and in a timely manner. There were several tax credits, renewable energy credits and grants that were available for my solar system and in my jurisdiction. Nova Solar made sure that each of the applications were completed and received for their system. When completed Nova Solar sent links to each of my electronic devices so I could have access to the system on line to track the daily energy production and to see any trouble with the system (which there have been none to date) at any time during the day. I have been in the subcontracting business for over 30 years and know a good subcontractor when I see one. I have had an excellent experience with Nova Solar and would highly recommend their services to anyone who is interested in solar energy."

Solar Panels questions, answered by experts

Solar panels should get at least four to six hours of direct sunlight daily. It’s even better if sunlight reaches panels between the peak hours of 10 a.m. and 3 p.m. This is enough to power a home, depending on your solar system’s size and energy needs. Remember that panels will generate some power under cloudy skies or in the shade, and many systems compensate for lower sun exposure by drawing energy from the grid or battery storage.

Learn about common solar blockers in your area to determine how often you should wash solar panels and the best cleaning method:

  • Soot: If you have a fireplace, soot can disperse and accumulate on the solar panels.

  • Debris, dirt, and leaves: These natural elements require light cleaning. Being close to trees or living in a desert area can cause more of these to accumulate.

  • Pollen: Areas with a high pollen count require more frequent solar panel cleaning, and sticky plant material requires a deeper cleaning.

  • Bird droppings: Bird droppings are binding and more difficult to remove. Keep this in mind if you live near a lot of surrounding trees. 

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.

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.

There are a few qualifying questions you should ask a local solar panel company before hiring them:

  • Will you handle permits for the installation?

  • Does your total price include the equipment and labor?

  • How long do you expect the installation process to take?

  • What kind of workmanship warranty do you include with your installations?

  • Who should I contact if I have a problem with my system after installation?

  • Do you install the panels or outsource the work to third parties?

  • Will you file for solar incentives for me?
