"Needed 10 year old solar panels removed and reinstalled to accommodate a new roof job. Rick and his crew at RCI are INCREDIBLE! The bid was very fair (compared to the original installer who wanted to rip us off); the work was completed as promised and Rick even initiated a warranty claim for 2 micro inverters we didn't even know were not functional. Rick is probably the most professional, ethical, and knowledgeable business person we've dealt with in quite some time. RCI was referred by a roofer we ended up not using, yet RCI still came through for us! Rick's team even spent significant time to fix the bad wiring job from the original installer at no extra cost I am thankful we switched from our original installer to RCI. HIGHLY RECOMMEND!"

"It would be wise to not sign an agreement nor pay upfront before doing a little research on what the job entails.

Solar Panels questions, answered by experts

Rooftop solar panels supply energy to a single household, where a solar farm can power multiple homes at once with clean energy. Residential rooftop solar panels cost more per watt with a lower project total, and those panels only service the residence they are installed on (in most circumstances). With a solar farm, multiple households can buy into the project and share the overall cost.

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 average homeowner needs around 22 solar panels, but the exact number depends on your monthly energy consumption. Your solar professional should size your array to offset your consumption, meaning you’ll need fewer panels if you use below-average amounts of electricity, or more than 22 if you use above-average amounts of electricity. The number of panels also depends on the output of each panel. The average is around 400 watts, but you might need more panels if you install less capable equipment. Since there are so many variables, you should have a professional size your system.

Most solar panels last 25 to 30 years and have a warranty to match. Over time, you’ll see a diminishing electrical output. This is normal wear, but certain things can hasten solar degradation. These include heavy rainfall, high temperatures, constant humidity that corrodes the frame, and cracks or chips in the glass.

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.
