The Solar Side Up Story

Solar Side Up originated from Jeff investigating and installing a 10K ground-mounted solar system in his back yard.  At the time it was nearly installed Jeff realized he needed professional help to wire-in his new power plant.   After an exhaustive search, Jeff found this small notice on the web about an electrician performing solar work.  Jeff called him up and wouldn’t you know it - Geoff the Master Electrician lived two blocks away in the same neighborhood.  Geoff came over and wired up Jeff’s solar.  Jeff knew right then once the solar was working that there was a business opportunity to get solar to people who wanted to save money on their power, control their own power and save the planet.
