"These green power purchases help reduce the environmental impacts of electricity use and support the development of new renewable generation capacity nationwide. Purchase amounts reflect U.S. operations only and are sourced from U.S.-based green power resources. Organizations can meet EPA purchase requirements using any combination of three different product options (1) Renewable Energy Certificates, (2) On-site generation, and (3) Utility green power products."
DC energy created by the PV panels runs into the inverter and creats an alternating current (AC). Then AC current is metered prior to heading back into the grid.
This chart shows Philadelphia averages 1600 kW-yr.
