Enter the total solar power generation (kW), the average hours of sun per day, operational costs ($), and the selling price of electricity ($/kWh) into the calculator to determine the Solar Farm Profit. 

Solar Farm Profit Formula

The following formula is used to calculate the Solar Farm Profit. 

SP = P * T *  ESP – C

  • Where SP is the Solar Farm Profit ($/day)
  • P is the total solar power generation (kW) 
  • T is the average hours of sun per day 
  • ESP is the selling price of electricity ($/kWh) 
  • C are the daily costs ($/day)

How to Calculate Solar Farm Profit?

The following example problems outline how to calculate Solar Farm Profit.

Example Problem #1

  1. First, determine the total solar power generation (kW). In this example, the total solar power generation (kW) is given as 2500 .
  2. Next, determine the average hours of sun per day. For this problem, the average hours of sun per day is given as  8 .
  3. Next, determine the selling price of electricity ($/kWh). In this case, the selling price of electricity ($/kWh) is found to be .56.
  4. Next, determine the daily running costs. In this case, the daily running costs are $200.00.
  5. Finally, calculate the Solar Farm Profit using the formula above: 

SP = P * T *  ESP – C

Inserting the values from above yields: 

SP = 2500 * 8 *  .56 – 200 = 11000 ($/day)


Example Problem #2

The variables needed for this problem are provided below:

total solar power generation (kW) = 5000

average hours of sun per day = 7

selling price of electricity ($/kWh) = 1.25

daily running costs ($) = 5000

Entering these values and solving gives:

SP = 5000 * 7 *  1.25 – 5000 = 38750 ($/day)
