Already on the grid

The sun's already at work.

Community solar farms across Maryland are generating power right now. You don't build them — you subscribe to a share, and the credits hit your existing utility bill every month.

Your building performs better. Your bill should too.

ZeroNet already knows your energy profile. Adding community solar is the natural next step — and it stacks perfectly with the efficiency work they've already done.

Efficiency + Solar = Maximum Savings

Your ZeroNet audit reduced waste. Community solar credits reduce your bill further. Together, you keep the most money possible.

They Already Know Your Building

With over 50,000 audits completed, ZeroNet understands Maryland buildings inside out. They'll recommend the right solar allocation for your actual usage.

Zero Cost, Zero Equipment

No panels on your roof. No installation. No deposit. The solar farm is already built. You subscribe to a share and your utility credits you every month.

Three steps. Five minutes.

Community solar is the easiest energy upgrade you'll ever make. No site visit, no equipment, no changes to your service.
