Battery Capacity Equation:
| From: | To: |
This calculator determines the required battery capacity (in ampere-hours) for solar energy systems eligible for Canadian government subsidies. It uses the official formula specified by Canadian renewable energy programs.
The calculator uses the official equation:
Where:
Explanation: The equation accounts for the conversion from energy (Wh) to battery capacity (Ah) while considering system inefficiencies through the Canada Factor.
Details: Accurate battery sizing is crucial for qualifying for Canadian government solar incentives, ensuring system reliability, and optimizing cost-effectiveness of solar installations.
Tips: Enter your total daily energy consumption in watt-hours, your system voltage (typically 12V, 24V, or 48V), and the Canada Factor (default is 0.85). All values must be positive numbers.
Q1: What is the Canada Factor?
A: This is an efficiency factor (typically 0.85) accounting for battery depth of discharge, temperature effects, and other losses as specified by Canadian subsidy programs.
Q2: How do I determine my Canada Subsidy Load Wh?
A: This is your total daily energy consumption, which can be calculated by summing the watt-hours of all devices you plan to power with your solar system.
Q3: What battery voltages are typically used?
A: Common system voltages are 12V, 24V, or 48V. Higher voltages are more efficient for larger systems.
Q4: Does this calculator guarantee subsidy approval?
A: While this calculator uses the official formula, final subsidy approval depends on meeting all program requirements.
Q5: Where can I find more about Canadian solar subsidies?
A: Visit Natural Resources Canada's website or consult with a certified solar installer in your province.
