1. What is a Solar Panel Installation Cost Calculator?

Definition: This calculator estimates the total cost of installing a solar panel system based on system size and cost per kilowatt.

Purpose: It helps homeowners and businesses plan their solar energy projects by providing a quick cost estimate.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Install Cost — Total installation cost (currency)
• Size — Solar system size (kW)
• Cost per kW — Installation cost per kilowatt ($)

Explanation: The system size is multiplied by the cost per kilowatt to get the total installation cost.

3. Importance of Solar Cost Calculation
