About the Founders

Long-time solar professionals Nate Preisendorfer and Erik Pickhardt have worked together at several solar companies in New England in the past, and have finally decided to combine their collective twenty+ years of expertise, in the founding of Seventh Gen Solar.
Nate Preisendorfer has worked as a project manager, fixer, and general go-to team leader in the solar industry for some years now, and brings with him a varied background, which has only served to enrich his enthusiasm for what he does. Prior to getting into the solar industry, Nate served in various international humanitarian relief organizations, before he decided to settle down with his Wife and two kids, and start a humble life for himself as a solar energy professional and a family man.
Erik Pickhardt, meanwhile, has worked in all aspects of the solar industry, from installation, to consultation, to design, to permitting and town planning, in addition to having personally lived with an off-grid solar system since 2011, and worked on off-grid and marine energy applications for much longer. Apart from his background in the solar industry, Erik can also speak to your interest in permaculture, hydro-thermal, and regenerative systems design, if you’re interested in abstruse suggestions you had no idea you were looking for.

Our Mission:

Seventh Gen Solar is a New-England based solar company rooted in the principles of environmental stewardship, social responsibility, and professional integrity.
We are fundamentally committed to the idea that our clients’ and our planets’ best interests should lie at the heart of everything we do. Consequently, we’ll be honest with you if solar isn’t a good fit for your property, and we’re not interested in gimmicky sales tactics or setting up unrealistic expectations for anyone at all, much less the clients we depend on.
Because we believe that access to solar energy should be as broad as possible, we offer some of the most competitive rates in New England, as well as top-notch service from a team of solar professionals who are genuinely interested in making sure your system meets your standards, as well as your expectations.
And most of all, we’re solar providers because we see the intrinsic value of solar energy, not just because it’s the most economical solution for most people to close the loop on their power demand, but because it’s something our kid’s kids can be thankful for, and their kids after them.
