Introduction
Calculating the cost per watt is an essential step in evaluating the financial feasibility of a solar project. This article provides an online calculator to help you determine the cost per watt of your solar installation accurately.
Formula
The formula for calculating the cost per watt for a solar project is straightforward:
Cost Per Watt = Total Cost ÷ Total Wattage
- Cost Per Watt: The cost per watt of the solar installation.
- Total Cost: The overall cost of the solar project.
- Total Wattage: The total wattage of the solar panels used in the installation.
By using this formula, you can assess the cost per watt, a critical metric for solar project evaluation.
How to Use
Utilizing the cost per watt calculator is a simple process:
- Enter the total cost of your solar project (in USD) in the first input field.
- Specify the total wattage of the solar panels used in the second input field (in watts).
- Click the “Calculate” button.
- The calculator will provide you with the estimated cost per watt of your solar installation.
Example
Suppose you have invested $15,000 in a solar project, and the total wattage of the solar panels used is 5,000 watts:
Cost Per Watt = $15,000 (Total Cost) ÷ 5,000 watts (Total Wattage) = $3.00 per watt
In this example, the cost per watt for your solar installation is $3.00.
