Quick Start (Optional): Pre-fill with a typical UK home or Hanchu ESS package Expand presets

UK Household Templates:

Hanchu ESS Complete Packages:

Solar Array 10 panels

Peak DC Size 4.65 kWp

Est. Annual Yield 5,754 kWh/yr

Battery Storage 9.4 kWh (8.9 kWh usable)

Est. Net Savings +£1,180/yr

Stage 1 of 4 • Location & Solar Array

Where is your property & what panels are on your roof?

Modelled for the latest Aiko Neostar N-Type ABC panels (455W–510W), Full-Array DC Power Optimisers on every panel, and Hanchu ESS Hybrid Inverter & Blade LFP technology.

Aiko N-Type ABC Panels (+4.5%)

23.8%+ efficiency, 0% front grid shading, -0.26%/°C temp coeff, superior UK diffuse/overcast output & 0.35%/yr degradation.

100% DC Optimisers Fitted (+5.5%)

Module-level MPPT on all panels eliminates string mismatch, chimney/gable shade bottlenecking, and extends dawn/dusk harvest.

Hanchu Hybrid & Blade LFP (+2.0%)

97.6% inverter efficiency, 50V early start-up, 200% DC oversizing direct to battery, 95% DoD & 94.5% DC round-trip efficiency.

UK Region & Solar Climate

Determines seasonal daylight hours and regional PVGIS solar irradiance.

1,080 kWh/kWp

Select your installation region:

Solar Roof Aspects (Strings) & Panel Wattage

Set orientation (azimuth), roof pitch, number of panels, and wattage per panel (up to 600W). Have panels on multiple roof sides (e.g. East & West)? Click + Add Roof String.

Hybrid Inverter AC Power Rating

Standard UK G98 fast-track grid limit is 3.68 kW; larger systems use G99 DNO approval (5 kW – 10 kW).

Stage 2 of 4 • Home Battery Storage

How much battery storage capacity do you want to model?

Batteries let you store cheap overnight grid power or daytime sunshine to run your home during expensive peak hours. Select a preset below or use the slider (set to 0 kWh for solar-only).

Total Battery Storage Capacity (kWh)

Choose a Hanchu Blade LFP model, a standard market size, or enter an exact kWh rating.

Fine-tune battery capacity (0 kWh to 30 kWh):

0 (Solar Only) 5.12 kWh 9.4 kWh 18.8 kWh 30 kWh

Max Battery Charge / Discharge Power (kW)

Determines how fast the battery can fill during short cheap overnight windows (typical LFP is 3.6 kW – 5.0 kW).

Up Next • Stage 3 of 4 Enter your household electricity usage and any planned EV or heat pump.

Stage 3 of 4 • Household Consumption

How much electricity does your home use?

Enter your current annual electricity consumption from a recent bill so we can accurately calculate your Before vs After Solar savings.

Current Annual Electricity Consumption

Select a typical UK household size or type your annual kWh figure from your bill.

kWh/yr
