Helped with installing solar and converting our gas electric house into just electric in 2014. It saves us a large amount of money per year as we no longer get power bills and even get some money back each year from the solar. Is actually more comfortable to live in for example: doing away with the awful swampy evaporative cooler and replacing it with a heat pump air conditioner humidifier, faster hot water from the heat pump hot water unit, and faster cooker and boiling of water on the induction cooktop.
