1. What is the UK Government Solar Calculator?

The UK Government Solar Calculator estimates potential savings from solar panels and battery storage using the Feed-in Tariff (FIT) rates. It helps homeowners understand the financial benefits of renewable energy installations.

2. How Does the Calculator Work?

The calculator uses the UK government formula:

Where:

• \( Generation \) — Estimated electricity generated by solar panels (kWh)
• \( FIT \) — Feed-in Tariff rate (£/kWh)

Explanation: The equation calculates potential savings by multiplying the amount of electricity generated by the tariff rate paid for renewable generation.

3. Importance of Solar Savings Calculation

Details: Accurate savings estimation helps homeowners evaluate the return on investment for solar panel and battery installations, and understand payback periods.

4. Using the Calculator

Tips: Enter your estimated annual generation in kWh and the current FIT rate in £/kWh. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the Feed-in Tariff (FIT)?
A: FIT was a UK government program that paid homeowners for renewable electricity generated. While now closed to new applicants, existing installations still receive payments.

Q2: How do I estimate my solar generation?
A: Generation depends on system size, location, roof orientation, and shading. Installers typically provide estimates.

Q3: Are there other savings besides FIT payments?
A: Yes, you also save by using generated electricity rather than buying from the grid (offsetting import costs).

Q4: How accurate is this calculator?
A: It provides basic estimates. Actual savings may vary based on usage patterns, system performance, and energy prices.

Q5: What about battery storage savings?
A: Batteries can increase self-consumption of solar energy, but require additional calculations beyond this simple FIT estimate.
