1. What is the Energy Equation?

The energy equation calculates total available energy by combining solar generated power with battery backup power. This helps in understanding your total energy capacity from both renewable and stored sources.

2. How Does the Calculator Work?

The calculator uses the simple energy equation:

Where:

• \( Solar\ Generated\ Wh \) — Energy produced by solar panels in watt-hours
• \( Backup\ Battery\ Wh \) — Energy stored in batteries in watt-hours

Explanation: The equation simply sums the energy from both sources to give total available energy.

3. Importance of Energy Calculation

Details: Calculating total energy helps in system sizing, understanding energy autonomy, and planning for energy needs during low solar production periods.

4. Using the Calculator

Tips: Enter solar generation and battery capacity in watt-hours. Both values must be non-negative numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert kWh to Wh?
A: Multiply kWh by 1000 to get Wh (1 kWh = 1000 Wh).

Q2: What's a typical solar generation for a home?
A: A 5kW system might generate 20-30kWh per day, depending on location and weather.

Q3: How much battery backup is needed?
A: Depends on your energy needs during non-sunny periods. Typically 1-3 days of autonomy is planned.

Q4: Does this account for system losses?
A: No, this is a simple calculation. Actual usable energy will be slightly less due to conversion losses.

Q5: Can I use this for off-grid systems?
A: Yes, this calculation works for both grid-tied and off-grid solar systems with battery backup.
