How much will I save with Solar Power on my monthly Electricity Bill?

It’s hard to determine the average power consumption of a building due to differences in nature of all buildings. The size of solar system you choose will depend on if you want to partially offset your energy consumption or completely offset your electricity use.

Solutions for Reducing your Electricity Bill

  • Increasing the temperature set point of your air conditioning in summers and in winters
  • Switching to energy efficient lighting so as to get a lower lighting power density (LPD)
  • Using a variable speed drive for your fans, it is more efficient
  • Replacing your old air conditioner with a better energy efficient rating

Solar Calculator for your house

Calculate the capacity of solar plant as per your rooftop area. Just enter your rootop area and the percentage of rooftop available for Solar plant.

How much energy storage do you need?

Figuring out how many batteries you need can be overwhelming. If you don’t have enough battery capacity, you run out of power and need to fire up the backup generator. So it’s important to know the storage capacity you require.
The amount of battery storage you need is based on your energy usage. Energy usage is measured in kilowatt hours over a period of time.
