Case Study: Solar by the Numbers

Eric of Marlborough

Solar Electric and Solar Hot Water



Kilowatt-hours, utility rates, SREC prices, rebate amounts, tax credits, net costs…the variety of numbers associated with installing solar energy systems can be mind-boggling. But for those with an appetite for data, solar-related numbers deliver a lot of satisfaction.

Eric of Marlborough, MA, is one of those customers. He waited years to install solar: “I became interested in the whole solar energy concept in grade school. In junior high, solar electricity was so expensive only NASA could afford it. I kept it in the back of my mind, and finally, the opportune time came–costs were within reach, and I was in a position to jump in.”

Since his 5,040-watt solar electric system went live in May 2010, Eric has tracked his production and savings diligently. So without further ado, we’ll let his numbers speak for themselves.







Eric on solar electric costs: “I was a little apprehensive regarding solar electric at first, because of the substantial commitment involved financially, plus the usual contractor-related give and take. It was a leap of faith for me, but one I felt was the right thing to do. I have been pleasantly surprised. The system performs very well, and now has a couple years of performance under its belt. I am very happy with my systems.”
