1. What is a Solar System Cost Calculator?

Definition: This calculator estimates the total cost of a solar power system based on its size and the price per kilowatt.

Purpose: It helps homeowners, businesses, and solar installers quickly estimate solar system costs for budgeting and planning purposes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Cost} \) — Total system cost in dollars
• \( \text{Size} \) — Solar system size in kilowatts (kW)
• \( \text{Price Per kW} \) — Cost per kilowatt in dollars

Explanation: The system size (in kW) is multiplied by the cost per kW to determine the total system price before incentives.

3. Importance of Solar Cost Calculation

Details: Accurate cost estimation helps in financial planning, ROI calculations, and comparing different solar options and quotes.

4. Using the Calculator

Tips: Enter the system size in kW and price per kW (default $3,000/kW). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's included in the price per kW?
A: Typically includes panels, inverters, mounting hardware, installation labor, permits, and sometimes monitoring equipment.

Q2: What's a typical price per kW?
A: Prices range from $2,500-$3,500 per kW in 2023, depending on location, equipment quality, and installation complexity.

Q3: Does this include tax credits or incentives?
A: No, this calculates gross cost. Deduct applicable incentives (like the 30% federal tax credit) separately.

Q4: How do I determine my needed system size?
A: Review your annual kWh usage and divide by your area's production ratio (typically 1.2-1.6).

Q5: Does this include battery storage?
A: No, this calculates grid-tied system costs only. Add 20-50% more for battery backup systems.
