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!!"
