Frequently Asked Questions

  • 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.

  • What are the main components of a solar power system?

    Solar modules (panels) and inverters are the main components of a solar power system and they constitute 70% of project cost.

  • How much area is required to install a rooftop solar system?

    1 kWp solar system requires approximately 10 sq. m (or 100 sq. ft) of shadow free area. Therefore, one 1 MWp (1000 kWp) solar system would require 10,000 sq. m / 1,00,000 sq. ft / 3 acres of shadow free area.

  • What is Solar system Sizing

    Solar system sizing is a process of deciding the capacity of the solar system by considering important factors

  • What factors are considered for Sizing
    1. Shadow free roof space available
    2. Sanctioned load if On grid system
    3. Consumption pattern
    4. Applicable policy (Net metering vs Gross metering)
    5. Purpose of going solar (Zero emission vs Electricity charges reduction)
  • 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

  • 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

  • What is Hybrid system

    Hybrid system gives the best of both On and Off grid system. 

    1. Hybrid system can work even when there is no grid power
    2. Excess power is used to charge Battery which can be used to reduce power import from grid and also a power backup during powercut
