On Grid with Net metering/ Off grid with Battery backup
On Grid System-
- Grid-Tie system allows you to sell excess electricity Back to the grid utility with net metering system.
- Work without batteries and hence very low maintenance and requires less monitoring Can be designed with and without batteries.
- If the demand of utility is more than power generated by solar array, the balance requirement of power will be drown from grid
or generator automatically.
Off Grid System-
- This type of solar electric system is not connected to electricity grid
- Stand alone system for remote areas.
- Can be designed to provide power for a certain number of days (nights) in row when sun is not available.
