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!
