Plankton Energy
This 182.25 kW rooftop community solar system sits on an office building in Waltham, MA. The energy generated is sold to individual households in the community.
350 Waltham Street is one of three office buildings on the same street where Plankton Energy operates rooftop community solar; the others are 358 Waltham Street (313 kW) and 360 Waltham Street (540 kW). Together the three systems put more than a megawatt of solar on roofs that previously earned nothing.
The building owner leases roof space to Plankton and earns lease income, while local residents and businesses subscribe to the array’s output and receive utility bill credits. Plankton developed, financed and built the system and handles monitoring, maintenance and subscriber management for its life.
