Aside from the savings that you could make on your electric bills by using solar panels, solar power is better for the environment. Solar electricity is green renewable energy and doesn’t release any harmful carbon dioxide or other pollutants. A typical home solar PV system could save 1.3 – 1.6 tonnes of carbon per year.
The larger the roof mass the more energy you can produce meaning the more energy you can generate, this is fantastic for large commercial businesses that often have larger carbon footprints and in turn larger energy bills too.
