Customized to your needs
- Grid-tied systems are photovoltaic (PV) systems that generate electricity with solar panels.
- Grid-tied systems are interconnected with the power grid through a grid interactive inverter.
- Electricity can flow TO or FROM the power grid depending on your needs and production.
- Systems can be mounted on the roof of a building, on poles or racks on the ground.
The size and capacity of the grid-tied system is calculated, such that over the course of a year the amount of power produced equals the amount of power consumed. During the summer there is an overproduction that builds a $ credit with the power company. During the winter months the credit is used to supplement power usage by buying power from the power company. This is known as Net Metering. A typical household will need a 5000–8000 Watt PV array to offset their annual power needs.
These grid-tied systems are virtually maintenance free. They depend on the power grid to function. In a power outage these systems cannot produce power and you will have no power. AC or DC coupling with a battery backup system can be added to existing or new systems to provide power to the whole house or critical appliances during a power outage.
