1. What is the Solar Panel & Battery Calculator?

This calculator determines the sale price for solar panel and battery combinations based on panel wattage, battery capacity, a pricing factor, and applicable discount percentage.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \text{Panel W} \) — Solar panel wattage
• \( \text{Battery Ah} \) — Battery capacity in amp-hours
• \( \text{Factor} \) — Pricing factor (decimal value)
• \( \text{Discount %} \) — Discount percentage (0-100)

Explanation: The formula combines the base panel price with the battery price (scaled by capacity) and applies the discount percentage.

3. Importance of Accurate Pricing

Details: Proper pricing ensures profitability while remaining competitive in the solar energy market. This calculation helps standardize pricing across different system configurations.

4. Using the Calculator

Tips: Enter panel wattage in watts, battery capacity in amp-hours, the pricing factor as a decimal, and discount as a percentage. All values must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: How is the factor determined?
A: The factor is typically based on battery type, market prices, and business costs. Common values range from 0.5 to 2.0.

Q2: Should the discount be entered as decimal or percentage?
A: Enter as percentage (e.g., 15 for 15%). The calculator automatically converts it.

Q3: What's a typical panel wattage range?
A: Residential panels typically range from 250W to 400W, while commercial panels can go up to 600W.

Q4: How does battery capacity affect price?
A: Larger capacity batteries (higher Ah) will increase the price proportionally to the factor.

Q5: Can this be used for wholesale pricing?
A: Yes, adjust the factor and discount percentage to reflect wholesale rather than retail pricing.
