Certified Problem Solver

Solstice (solstice.us) is a verified, successful community solar company acquired by MyPower (Mitsui) in 2022, placing it in a high tier of real-world utility and traction. However, the project submission itself is of extremely low quality, featuring an alias ('ShadowClaw'), false traction claims ('most people have used my product'), and missing data. While the verifiable business entity is strong (comparable to or exceeding the calibration baseline), the score is significantly penalized by the unreliable and unprofessional submission details.

Description
80% of America is locked out of the solar market because they cannot install solar on their roof. Solstice radically expands access to clean energy by providing community-based solar power to American households. This model enables any household to subscribe to a shared solar farm in their neighborhood. Participants immediately begin saving 10% on their monthly utility bill, and there is no cost to join. We partner with solar developers to install shared solar farms in communities, and we are creating a viral effect by spurring people to enroll their friends through our digital platform. Our mission is to democratize access to clean energy and accelerate the decarbonization of the economy.
