1. What is a Domestic Solar Electric System Calculator?

Definition: This calculator estimates the financial savings from a domestic solar electric system based on energy generation and feed-in tariff rates.

Purpose: It helps homeowners evaluate the financial benefits of installing solar panels by calculating potential savings from generated electricity.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Savings \) — Total financial savings (currency)
• \( Generated\ kWh \) — Electricity produced by solar system (kilowatt-hours)
• \( Feed-in\ Tariff \) — Rate paid for generated electricity (currency per kWh)

Explanation: The total energy generated by the solar system is multiplied by the rate paid for each unit of electricity to determine total savings.

3. Importance of Solar Savings Calculation

Details: Accurate savings estimation helps homeowners understand return on investment, payback period, and long-term benefits of solar installations.

4. Using the Calculator

Tips: Enter the total generated kWh (typically available from solar system monitoring) and your local feed-in tariff rate (default 0.15 currency/kWh). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my generated kWh?
A: This is typically available from your solar system's monitoring software or inverter display.

Q2: What's a typical feed-in tariff rate?
A: Rates vary by location and utility company, but 0.10-0.20 currency/kWh is common in many areas.

Q3: Does this include all solar savings?
A: This calculates only feed-in tariff savings. Additional savings come from reduced grid electricity purchases.

Q4: Should I use annual or monthly kWh?
A: Use the time period you want to analyze (monthly, annual, or system lifetime).

Q5: How accurate is this calculation?
A: It provides basic estimates. For precise figures, consult your solar installer or utility company.
