Solar on Grid System
A Grid -Connected Solar Roof Top Photovoltaic Power System is an electricity generating system that is connected to the utility grid. A grid Connected PV System consists of Solar panels, one or more Invertors, AC/DC Cables, ACDB/DCDB, Earthing Protections etc. and Grid Connection equipment, supplies the power to utility grid.

How to Calculate On-Grid Solar System’s size for your House/Factory etc
Average daily consumption in kWh can be calculated from the electricity bill as follows:
- Calculate the monthly average energy consumption from last 12 months’ electricity bill.
- Let us consider a Monthly average consumption in units for a consumer is 400 units (after averaging for 12 months)
- Daily average unit consumption can be calculated by dividing the monthly unit consumption by 30
- Average daily consumption is 13.3 kWh /day approximately 14 units
- Now 1 KW of Solar System generates 4 units / day (Average generation in India).
- So, to generate 14 units per day we will require approx. 3.5 kW of Solar System.
In this way , you can calculate the approximate requirement of Solar System at your own. Here are some ranges of units and the size of the solar power plant that can be installed at your home.
