Community-Owned Solar Gardens Make Clean Energy Possible for All
One of the biggest setbacks for people looking to invest in solar is a lack of a suitable place to put the solar panels. A solar installation both has to be in the right direction and the right angle to extract enough energy from the sun’s trajectory for the system to be financially feasible.
When we add up the numbers, only about 1 in 5 American households is suitable for solar, which means that the vast majority of the population cannot contribute much in the solar movement even if they wanted to.
In the last few years this has been changing: community-owned solar enables households that otherwise wouldn’t be eligible for solar panels in the past to invest in, and make use of, this technology.
How does community-owned solar work?
Currently, solar energy can be stored or shared in three ways. If households with solar panels generate more electricity than what they need, they have to have a place to store that electricity. In an off-grid situation, for instance, this is done with batteries. Net metering, on the other hand, involves sending excess electricity to the power grid, and crediting the solar array owner’s bill accordingly. A newer option, virtual net metering, allows more than one household to use the same net metering program, with each one of them receiving credit in terms of lower electricity bills as a ratio of their own share of the PV system. Virtual net metering is only available in a few US states, with others considering it.
Community-owned solar, or “solar gardens,” offers a way for households to purchase or lease a certain percentage of a collection of solar panels. A solar garden can be put on a flat piece of land or on a large rooftop in the community, enabling those 4 in 5 American households that aren’t suited for residential solar panels harvest clean electricity after all.
