When to choose Mono type panels

If you dont have enough roof space for the capacity that you wish to install, mono crystalline type panels can be chosen. The monocrystalline panels generates more watts when compared with Polycrystalline panles.

8. What is Hybrid system

Hybrid system gives the best of both On and Off grid system. Hybrid system can work even when there is no grid power Excess power is used to charge Battery which can be used to reduce power import from grid and also a power backup during powercut

7. What is Off grid system

Off grid system is suitable where there is no exiting Electricity grid connection. Batteries will be installed to store power for the usage in the night when there is no solar power generation.

6. What is On grid system

The Solar system is connected to the Electricity Grid. Excess electricity produced beyond the household consumption is exported to the grid. When there is no Grid power then the Solar system will not work.

4. What factors are considered for Sizing

Shadow free roof space available Sanctioned load if On grid system Consumption pattern Applicable policy (Net metering vs Gross metering) Purpose of going solar (Zero emission vs Electricity charges reduction)

1. How does a solar Photovoltaic (PV) power work?

Sunlight (light, not heat) on photovoltaic modules produce direct current (DC) electricity which is converted to alternating current (AC) by a device called an inverter, which is then wired into your main service panel where it feeds your internal power grid.
