Here are some scenarios to help you map your solar needs and the resulting gains

Rooftop project

An industrial unit with a connected load of 150 kW has a monthly consumption of electricity at an average tariff of Rs. 9 per unit. It has a total roof area of 12,000 sq. ft. with some obstructions.

  • Area wasted due to shadow creating obstructions = 2000 sq. ft.
  • Usable area = 10,000 sq. ft.
  • Recommended solar capacity = 100 kW
  • Monthly savings on electricity bill = Rs. 1,08,000 approx.

Lifetime sustainability gains:

  • Trees saved = 4,700 approx.
  • Reduction in CO2 emissions = 2,826 metric tons approx.

Utility-scale project

A developer intends to install a 12 MW grid-connected solar power plant.
Depending on module rating, installation type (fixed/tracker) and location of plant, these are the details.

  • Land required = 45-50 acres
  • Lifetime generation = 49,27,50,000 units approx.

Lifetime sustainability gains:

  • Trees saved = 5,64,000 approx.
  • Reduction in CO2 emissions = 3,39,120 metric tons approx.
