Different Types of Solar Systems
When using solar energy, there are three different types of systems to choose from: a grid-tie system, a grid-tie system with battery backup or an off-grid system. Whichever you choose they all offer many benefits.
A Grid-Tie System
is linked to a power utility company, which is then connected to your household power. If the amount of energy produced is less than the amount of energy needed, electricity from the power utility company will make up the difference.
Battery Backup Solar
A grid-tie system with battery backup
is similar to a regular grid-tie system, the difference being that if the power goes out with your electric company you have a battery backup that is still providing power to your home.
An off-grid system
provides complete independence to its users, with no reliance on power companies.
