Solar Experiment Lets Neighbors Trade Energy Among Themselves

Brooklyn is known the world over for things small-batch and local, like designer clogs, craft bourbon and artisanal sauerkraut.

Now, it is trying to add electricity to the list.

In a promising experiment in an affluent swath of the borough, dozens of solar-panel arrays spread across rowhouse rooftops are wired into a growing network. Called the Brooklyn Microgrid, the project is signing up residents and businesses to a virtual trading platform that will allow solar-energy producers to sell excess-electricity credits from their systems to buyers in the group, who may live as close as next door.

The project is still in its early stages — it has just 50 participants thus far — but its implications could be far reaching. The idea is to create a kind of virtual, peer-to-peer energy trading system built on blockchain, the database technology that underlies cryptocurrencies like Bitcoin.

The ability to complete secure transactions and create a business based on energy sharing would allow participants to bypass the electric company energy supply and ultimately build a microgrid with energy generation and storage components that could function on their own, even during broad power failures.

Great. Your address is perfect for solar. Solar incentive is still available. Select monthly utility cost and calculate the size of solar system you will need now.

Whoa ! Going solar is definitely a smart decision.
