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)

To calculate solar farm profit, multiply the power generation by the total time of generation, then multiply by the selling price of electricity, and finally subtract running costs.

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)
