Community Solar - Democratizing access to solar energy, through a monthly subscription, without the need for an investment

Community Solar (CS) is a solar plant whose electricity is shared by multiple users thus democratizing access to affordable solar energy.

Customers can rent a solar "share", enabling them to go solar without the need for a suitable roof, or a roof at all. This makes it an option for those who rent the property they live or work at. They have the option to not build a PV system on-site due to lack money or their preference for other investments. The Cummunity Solar is based on a “monthly solar subscription program” that can be summarized in three steps: (1) Participants pay a monthly fee for a share (in % of total kWp [kilowatt peak] capacity) of a solar PV plant that is located off-site to maximize technical efficiency. (2) The electricity produced by the solar plant directly flows into the grid, under a net-metering scheme. (3) In exchange for the monthly fee, each participant gets the credits of the kWh produced every month by their solar share directly on their monthly electricity bill. The subscription plans may vary in duration and share size.
