RESIDENTIAL SOLAR POWER SYSTEMS
Learn the Essentials
Grid-tie systems provide an additional source of power to your breaker panel in order to reduce utility power use during the daytime. Additionally, when more solar power is generated than the home can use, extra solar power flows onto ("backfeeds") the grid. The utility meters any power back-fed to the grid for a monthly credit (at a wholesale rate).
Off-grid power systems are designed to integrate multiple energy sources including solar power and backup generators to charge a battery and power the home. Off-grid solar is especially suitable for locations where grid power is unavailable, unreliable, or cost-prohibitive.
Combining a grid-tie solar power system with an energy storage (battery) system provides added features including backup power, enhanced solar performance (self-consumption), and time-of-use management (to reduce utility peak demand charges).
To enhance charging speed and efficiency, an EV charging solar inverter can simultaneously charge the vehicle directly from solar power at boosted speeds while also being connected to the home and grid like a regular grid-tie system.
