Unfortunately, we no longer accept requests through Angi or Homeadvisor due to the number of fake contacts we have received. So, if you would like to contact us here at GRID, you must do so directly through our website or phone. If you would like more information, you can either call or text our toll free number 833-474-3552, or visit our website www.GRIDSOLARLLC.com\n\nWe are a locally owned and operated solar company. We have seen the gimmicks and scams the big companies have been using and decided educate people about how solar REALLY works. We sell fewer systems because of how we operate, but we're okay with that because we do it the right way. \n\nThanks!

"Randy has been amazing since day 1! We ran into some issues with some solar companies and he helped us every step of the way! In no way was he ever pushy, just very informative and helpful. Even after install, when we have questions he is always there! He even went above and beyond during install and sat at our home on a day we were unable to be there! Thank you Randy and Sunny!!"

Solar Panels FAQs, answered by experts

DIY solar panel installations are hard to manage by yourself. You’ll likely need some help or prior experience to make the project worth the effort.

Solar panels have a life span between 10 and 40 years, depending on the type of panel. For example, monocrystalline panels can last up to 40 years, while thin-film ones only last between 10 and 20 years. The longevity also comes down to keeping up with solar panel repairs and their related costs .

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. 

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.

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.
