The solar panel quote calculator at Green Central UK is designed to provide homeowners with a tailored estimate for a solar panel system by analysing key factors about their property and energy needs.

Below is an explanation of how it works:

1. Scanning Your House

Virtual Assessment

The calculator likely uses a combination of user-provided data and advanced technology to “scan” or assess your home. 

This may involve integrating tools like satellite imagery, Google Maps, or aerial data to evaluate your roof’s size, orientation, pitch, and shading. 

Some modern calculators prompt users to input their postcode or address, which allows the system to pull location-specific data, such as sunlight hours and regional solar output potential.

Roof Suitability

The tool analyses roof characteristics, such as size and Space: Determines how many panels can fit (e.g., an average UK home can accommodate 6–16 panels, requiring 10–20 m² of unshaded space).

Orientation and Pitch:

South-facing roofs with a 10–60° angle are ideal for maximum solar generation. East or west-facing roofs are also viable but produce less.

Shading

Identifies potential obstructions like trees or nearby buildings that could reduce efficiency.

User Input

You may be asked to provide details like house size (e.g., number of bedrooms), roof type, or whether the property is listed or in a conservation area, as these factors affect installation feasibility and costs.

2. Estimating the Number of Panels Needed

Energy Consumption Input

If you provide your annual electricity usage (in kilowatt-hours, kWh, typically found on your energy bill), the calculator uses this to estimate the system size required. 

For example:

A typical UK home consumes around 3,500–4,000 kWh per year.

A 4kW system (producing ~3,400 kWh annually) often suits a 2–3 bedroom home, requiring 10–12 panels (assuming 350–405W panels).

Default UK Averages

If you don’t know your usage, the calculator defaults to national averages based on your home type:

1–2 bedroom homes: ~2,500–3,000 kWh/year, needing ~6–8 panels (2.1–3kW system).

3–4 bedroom homes: ~3,500–4,500 kWh/year, needing ~10–14 panels (3.5–4.5kW system).

Panel Efficiency

The calculator factors in panel efficiency (e.g., monocrystalline vs. polycrystalline) and local sunlight conditions (e.g., southern UK homes generate ~4,200 kWh/year for a 4kW system, vs. 3,400 kWh for solar panels in Scotland).

Output Calculation

It divides your estimated or average consumption by the expected annual production per panel (adjusted for location and roof conditions) to recommend the number of panels.

3. Battery Storage Recommendation

Why Battery Storage?: Batteries store excess solar energy for use when panels aren’t generating (e.g., at night or during outages), increasing self-consumption and savings. Without a battery, ~50% of generated energy may be exported to the grid.

Sizing the Battery

The calculator recommends a battery based on your system size and usage patterns:

For a 4kW system producing ~3,400 kWh/year, a 5–10 kWh battery is often suggested for a 3-bedroom home, as it can store enough for evening use.

It may consider whether you’re home during the day (higher daytime usage reduces battery needs) or rely heavily on evening power (requiring larger storage).

Cost Estimate

Battery costs range from £2,500–£8,000, depending on capacity and brand (e.g., a 5kWh battery like the Enphase IQ 5P costs ~£5,000). The calculator includes this in the quote if selected.

Benefits Factored In

It highlights increased savings (e.g., ~£150–£300/year extra by storing energy instead of exporting) and reduced grid reliance (up to 73% less grid electricity).

4. Calculating Potential Savings

With known electricity usage, the calculator uses your provided kWh consumption and current electricity rates (e.g., 27.03p/kWh in 2025) to estimate savings.

Example: For a 4kW system producing 3,400 kWh/year, if you use 80% directly (2,720 kWh), you save ~2,720 × 27.03p = £735/year on bills.

With the Smart Export Guarantee (SEG), excess energy exported to the grid earns 4–20p/kWh, depending on the tariff. For 20% exported (680 kWh), at 15p/kWh, you earn ~£102/year. Total savings: ~£837/year.

If usage isn’t provided, it assumes average consumption for your home type (e.g., 3,500 kWh/year for a 3-bedroom home).

Savings are estimated similarly, e.g., a 4kW system might save £550–£800/year (bills + SEG), with a battery adding £150–£200.

Payback Period

The calculator divides total costs (e.g., £7,000 for a 4kW system, or £12,000 with a 5kWh battery) by annual savings to estimate the break-even point (typically 8–15 years for panels alone, 15–26 years with a battery).

Incentives Factored In:

• 0% VAT: Saves ~£2,850 on a 4kW system until March 2027.
• SEG Payments included in savings projections based on estimated exports.

5. Additional Features and Outputs

Cost Projections: Provides an itemised estimate, including panels, inverter, brackets, labour, and optional battery storage. Installation complexity (e.g., scaffolding needs) may adjust costs.

Environmental impact can be measured with an estimate CO₂ savings (e.g., a 3kW system saves ~1 tonne/year, equivalent to 3,000 fewer miles driven).

Customisable Scenarios allow you to adjust parameters (e.g., panel number, battery inclusion) to compare costs and savings.

Next Steps: Offers options to save the estimate, request a detailed quote, or book a site survey with a certified installer for precise recommendations.
