1. What is the Solar and Battery Cost Calculator?

This calculator helps estimate the total cost of solar and battery systems purchased from Amazon UK by adding the base price to the battery cost based on size and adder rate.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• Amazon Price — Base price from Amazon UK (£)
• Battery Size — Capacity of the battery (kWh)
• Adder — Additional cost per kWh capacity (£/kWh)

Explanation: The equation calculates the total system cost by adding the base price to the battery cost which depends on its size and the per-unit adder cost.

3. Importance of Cost Calculation

Details: Accurate cost estimation is crucial for budgeting solar and battery installations and comparing different system options.

4. Using the Calculator

Tips: Enter the Amazon price in pounds, battery size in kilowatt-hours, and adder cost in pounds per kilowatt-hour. All values must be non-negative.
