Energy Costs of Constructing Solar Assets

This data-file quantifies the energy costs of manufacturing solar panels, based on 10 studies and prior projects.

We see the average solar project requiring 5MWH/kW, with a 2.3-year energy payback, a c10x energy-return on energy-invested and CO2-intensity of 90kg/boe (for contrast, average oil is c440kg/boe and average gas is c350kg/boe).

The data-file contains calculations and data on different, individual studies, and estimates the net impact of solar on fossil fuel demand – past and present – after reflecting the net energy costs of solar manufacturing.
