Town of Durham solar PPA

651 kW solar array installed for the Town of Durham in Lee, New Hampshire by ReVision Energy.

A solar power purchase agreement, or solar PPA, allows schools, nonprofits and municipalities, who cannot take advantage of federal tax programs, to enjoy the same benefits of clean solar power afforded to businesses and homeowners – and ultimately own the system. Solar energy is a fantastic way to lock in reliable costs of electricity for decades while reducing your organization’s impact on the climate.

Buy Power from a Solar Array, not the Grid

A solar PPA is an innovative financial structure which eliminates the #1 barrier to a nonprofit going solar – access to upfront capital. No upfront capital investment is required in a solar PPA. Instead, we pair an interested nonprofit, municipality, or school with a private solar investor, who can take advantage of federal tax programs not available to the nonprofit. The investor (often a values-aligned impact investor) then offers to purchase and build a solar array at the nonprofit’s location, and then sells the solar power generated from that array to the nonprofit at electric rates defined in the offer letter.

Exact pricing of the PPA offer will vary based on market, size of array, and other technical variables, but in general the solar PPA will present the municipality or nonprofit with a very competitive rate for electricity, and the lowest 40-year cost of electricity from any source. The solar array’s generation is tied into the nonprofit’s electric meters, meaning that the municipality’s or nonprofit’s consumption from the electric grid is reduced proportionally by the generation of the solar array.

All of ReVision’s solar PPA offers include a path to ownership after 7 years, allowing the nonprofit entity to ultimately own the solar generating assets and save a much greater amount of money in the long-term. Nonprofits may also opt to continue making payments on the solar array for 20 years and purchase in year 21.

What Maine’s New Legislation Means for Solar For Municipalities

Solar energy offers municipalities the opportunity to reduce long-term energy costs and carbon pollution – and now with the passage of Maine’s new solar bill (LD 1711), solar is more financially attractive than ever.

In this video conversation, Fortunat Mueller of ReVision Energy and Julie Rosenbach of the City of South Portland about the new solar bill, its implications for municipalities, and how municipalities of all sizes can benefit from integrating solar into their energy planning.

The Road to an Installed Solar PPA


ReVision Energy co-founder Bill Behrens and Thomas College staff member Chris Rhoda discuss the private-public partnership that resulted in building one of the largest solar arrays in Maine.

The first step in exploring a PPA is to contact ReVision Energy and start a process of site evaluation. Usually we start with a general conversation that goes in more detail about what a PPA is and how it works, and request energy data usage at your site. Once we receive this information, ReVision’s engineers will evaluate your site for solar opportunities, and then our finance team will develop the potential solar sites into an offer that can be presented to your organization.

Upon acceptance of a solar PPA, the approved solar project is installed by our team of highly trained solar professionals. We provide complete ‘turnkey’ service ranging from project management, permitting/interconnection, construction, and service and support for the life of the system.

During the first six years of the system’s operation, your organization would be billed for generation of the solar facility. After six years, your organization has the opportunity to purchase the system outright for a much reduced capital cost vs. the initial construction price, and then enjoy 25+ years of clean energy. Alternatively, your organization can continue to purchase the electricity from the solar PPA project up through year 20, and purchase in year 21.

Why Go Solar?


New England’s solar resource is strong, thanks to bright, cold winters and long summer days. Annually, a solar array in Maine or New Hampshire will produce a comparable amount of power to the same system installed in Austin, Texas. And since electricity is relatively expensive in the Northeast, the value of the New England system is higher than that of the system in Texas.

Solar power is also the clear environmental winner, with no moving parts, extremely long-lived equipment,and no emissions in the generation of electricity.

Further, a solar PPA is a powerful statement to your community that solar energy is a viable solution for New England. Rather than purchasing carbon credits or other forms of offsetting fossil fuel impact, a solar investment is incredibly tangible and a recurring statement of your organization’s commitment to a clean energy future.

ReVision has a robust marketing team and as part of a solar PPA roll-out we can develop awareness materials for the solar array such as lobby kiosks, online real-time performance monitors, posters, or flyers. We also frequently collaborate with our PPA hosts for solar tours, open houses, and other events.

Am I Right for a Solar PPA?

Ideal sites for solar PPAs include:

  • Schools or non-profits located in Maine, New Hampshire, and Massachusetts
  • Any size, from small Montessori school to large institution

Successful solar PPA projects by ReVision feature:

  • Path to ownership
  • No upfront capital cost
  • Lowest 40-year price of power vs. any other source
