Solar for Conservation
Harnessing solar energy to support Montana’s wild places.
At OnSite Energy, we believe in protecting Montana’s public lands, wildlife, and wilderness. That’s why we created Solar for Conservation—a program that gives back to local conservation nonprofits when you choose to go solar.
By installing solar with us, you’re not just reducing your carbon footprint and energy costs—you’re directly supporting organizations working to preserve Montana’s natural landscapes for future generations.
Through this initiative, we partner with Montana-based conservation nonprofits, providing funding and resources to help them continue their important work.
Nonprofits we currently support:
- Backcountry Hunters & Anglers
- Five Valleys Land Trust
- Gallatin Valley Land Trust
- Greater Yellowstone Coalition
- Montana Land Reliance
- Montana Trout Unlimited
- Montana Wildlife Federation
- Northern Plains Resource Council
- Public Land and Water Access Association

🌎 You go solar. OnSite gives back. Everyone wins.
