The original edition of Community Solar Power received a lot of attention, for which we at the Institute for Local Self-Reliance are very grateful. The grading system we used for community solar projects was of particular interest, especially our offer of higher scores for projects placed on rooftops rather than on the ground.
In particular, the excellent folks at the Clean Energy Collective (whose project is featured in this report) engaged us on the criteria we used for rooftop and ground-mounted solar power. After several in-depth conversations, we offer this revision to Community Solar Power and to the grades we provided for solar project location. We think that our revised grading system better reflects the advantages of distributed renewable energy as well as the best efforts of community solar projects to provide their participants with the best value.
