Solar Power Systems
Grid Connect and Off Grid
There are two main types of residential solar systems; a grid connect installation and an off grid installation.
What is a grid connect solar power system?
Grid connect systems are the most common solar power set ups in residential areas. They convert sunlight into electricity for home use, while also feeding any excess power back into the main electricity grid. Energy providers buy this excess electricity at an agreed price (known as a feed-in tariff) from customers which can help contribute to a reduction in their energy bills.
What is an off grid solar power system?
Off grid systems are commonly used in rural areas when connections to main power grids are either unavailable or very costly.
During the day, off grid installations power homes using direct sunlight. Any excess solar power not used by the home during the day is stored in the installation’s battery bank. When the sun goes down, and the panels stop generating power, the battery bank can be used to power the home’s electricity needs. A generator is usually on hand to back up the battery system.
