Solar & Sustainability Project Donation Application Questions

What is required to be eligible for a sustainability grant from the Sun Club?

See the basic requirements on the Apply for a Donation page.

Does the Sun Club help its recipient organizations find the right installer for their solar installations and sustainable projects?

The Sun Club offers assistance in identifying qualified vendors for sustainable projects. Grant recipients often find our experience with the bidding and installation process to be helpful.

How much insurance is needed to own a solar facility?

Insurance needs vary based on the facility and installation. You should speak to your insurance agent for information about insurance coverage and costs.

How long will a solar array last?

The expected useful life of a typical system is about 25 years.

What type of maintenance is required for a typical solar array?

Because there are no moving parts, very little. Photovoltaic panels require infrequent cleaning to remove any built-up dirt, pollen or other materials that can reduce the efficiency of the system. If you live in a humid environment, rainfall may be sufficient to keep your panels clean.

Can my organization apply for a Sun Club sustainability grant or solar energy donation at any time?

Yes, the Sun Club is always accepting new applications for both. Sustainability grant recipients will be chosen on a rolling basis by the Sun Club board of directors.

Recipients of solar energy donations are chosen the summer prior to the calendar year they will be awarded. For this reason, a call for applications is typically sent out in the spring or early summer before the deadline. Applications received after the deadline will be considered for the following year.

How big are the donations given away each year?

Donation amounts depend on a number of factors, including:

  • Needs of recipient organizations
  • Number of applicants
  • Available funds collected from our generous supporters

Past donations have ranged from a few thousand dollars to $140,000. Whenever possible, the Sun Club works with project installers to ensure grant recipients benefit from rebates and other incentives available through third parties.

Are Sun Club grants limited to rooftop solar installation projects?

No, the Sun Club has donated funds for the installation of solar water heaters, solar-powered trash compactors and vehicles, solar lights and solar educational materials, in addition to solar photovoltaic (PV) panels. We've also expanded our mission to support other sustainability projects that include but aren't limited to:

  • Water quality and conservation
  • Energy-efficient workplaces
  • Environmental protection
  • Waste management and reduction

We are open to new, creative ideas from non-profit organizations interested in utilizing and promoting sustainable living through renewable technologies.

Does the Sun Club donate and own the actual equipment for the sustainability projects it supports?

The Sun Club donates the funds for the recipient organization to purchase, install, or enact the sustainability project. The non-profit receiving a sustainability grant owns and is responsible for the project, along with any contracts or warranties with installer and manufacturer. The non-profit receiving a grant is also responsible for the upkeep and maintenance of the project if applicable.

Can I apply for a sustainability grant for my home?

No, solar donations are reserved for non-profit organizations with socially responsible missions. Exceptions may be made in the case of homes for low-income individuals built through a non-profit, such as Habitat for Humanity.

* Green Mountain Energy Sun Club is a non-profit organization formed under Section 501(c)(3) of the U.S. Internal Revenue Code.
