First, the good news: The world now has over 1.7 terawatts of cumulative solar capacity and solar PV is the lowest-cost source of energy generation worldwide.

The challenge: The world must build 3 terawatts of new solar capacity every year for the next 25 years.

Planted is creating new technology to overhaul how the industry develops and builds solar power resources. And we need help. We're expanding our team of ambitious, curious, and hands-on engineers and operators. Come own large parts of product, company, or business development and help power the world with 100% clean energy.
