1. What is a Solar Installation Cost Calculator?

Definition: This calculator estimates the total installation cost of a solar power system based on system size and installation rate.

Purpose: It helps homeowners and businesses estimate the upfront costs of solar panel installations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Install Cost — Total installation cost (currency)
• Size — Solar system capacity (kW)
• Install Rate — Cost per kW of installed capacity (currency/kW)

Explanation: The system size in kilowatts is multiplied by the installation rate per kilowatt to determine total cost.

3. Importance of Solar Cost Calculation

Details: Accurate cost estimation helps with budgeting, financing decisions, and ROI calculations for solar investments.

4. Using the Calculator

Tips: Enter the system size in kW and installation rate (default $2.75 per watt). All values must be > 0.

5. Frequently Asked Questions (FAQ)
