Andy and Randi are both environmental lobbyists who believe that they should “walk the talk,” and are doing so with solar power. The Astrum Solar installation on their DC home is Andy’s fourth photovoltaic system purchase. Andy’s other experiences with solar were on homes in Oregon.

“The choice is the right thing to do environmentally and the right thing to do financially. Most folks don’t appreciate how rational an investment it is. It’s good for the pocketbook and good for the Earth,” said Andy. “I project this to be a 20% return on investment over the minimum 25-year life of the system. SRECs are a game changer in the economics of PV solar power systems. I have often wondered why people have different requirements for the return on solar than on their 401(k). Money you don’t have to spend on electricity is money you don’t have to earn and pay taxes on.”

Inverter technology has been improving dramatically over the years since my first system installation in 2000. I get the maximum power production with Enphase. They are the “state-of-the-art” of today.

When the Capitol Hill Energy Coop was formed, Andy was recruited to be part of the steering committee because of his technical expertise and PV solar experience. Astrum Solar was one of the 10-12 companies the steering committee interviewed and was one of four companies that made the final Coop list of vetted vendors. Andy invited three of these companies, including Astrum Solar, to bid on his own project. “Astrum Solar appeared professional and knew what they were talking about. I chose them because of their pricing, their use of Enphase microinverters and the company culture,” said Andy.

“Inverter technology has been improving dramatically over the years since my first system installation in 2000.” Andy further explains, “In a tight urban environment with a central inverter, if you shade one panel, they all lose production. With microinverters that doesn’t happen. I get the maximum power production with Enphase. They are the “state-of-the-art” of today. Plus, it is fun to look at the online performance monitor.”

“My experience with Astrum Solar was pretty painless. With them pulling the permits, helping get the District of Columbia subsidy, and buying the Solar Renewable Energy Credits, it made it all easier.”

“It is not the first time so I knew what to expect. But nonetheless, it is still fun as ever to watch the meter spin backward,” said Andy.
