A solar park or a solar farm is a piece of land containing photovoltaic panels that generate electricity from the sun. Sizes can vary from just a couple of acres to more than 200 acres. The solar panels are placed on a specialized scaffolding often oriented to the south, to receive the highest irradiation possible. As a result, they deliver power to the grid via an inverter and a transformer. The energy supplier then provides real green electricity to private individuals and companies.
