Community Solar Gardens are centrally-located solar photovoltaic (PV) systems that provide electricity to participating subscribers. Could it work for you? Are you interested in going solar but unable to do so on your own? Perhaps you live in an apartment, have a shaded roof at home, or don’t have space at your organization. This presentation can help you learn more. For further resources, visit http://www.cleanenergyresourceteams.org/solargardens.
