"While I was very pleased with the design and installation process, the post-installation service is not responsive. One day after going live, the new Franklin WH battery system that was recommended started causing issues with production. They have been out twice to work on it, but only after multiple contacts and pleading. Currently, I have a $24K battery system I had to power down just to keep the solar system going. Unfortunately, they recommended (and I agreed) to install this cutting edge solution based on faulty manufacturer advice. Supposedly it is compatible with Enphase but in reality it is not, so it is not not their fault. I just wish there was as much energy put into getting the system operational as there seems to be with getting the system installed."

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!

"We've really had a good service, the system was like how they told and explained to us, they answered any questions we have. We really think the installers knew what they're doing and also answered our questions."
