System Guides

Find the right solar system for your roof and house size.

Find the Right Solar System for Your Home

Every home is different. A 3-bed terrace with a south-facing roof needs a completely different solar setup than a 5-bed detached with an east/west split. Most solar guides give you generic advice. These guides give you specific system recommendations based on your actual roof orientation and house size, with real component specs, string voltage calculations, and worked ROI figures.

Each guide covers a budget option and a premium option, with three panel selection strategies per system: best value (cheapest per watt), smallest footprint (fewest panels for tight roofs), and maximum overpanelling (lower-Voc panels to squeeze more onto each string).

Solar Energy Concepts System Rating

We score every system option against three metrics so you can compare at a glance:

Cost1 = accessible • 10 = premium only

12345678910

Consumption FitHow much of what you generate you actually use directly

LOWMIDHIGH

Tariff Exposure1 = ROI from self-consumption • 10 = depends on export rates

12345678910

A high-consumption household running a heat pump and EV will typically score low on tariff exposure (1-2) because they consume almost everything they generate. A system designed around Octopus Agile arbitrage with a large battery scores high (8-10) because the entire business case depends on half-hourly pricing staying favourable.

Solar Panels for a 4-Bedroom House with South-Facing Roof

South-facing roofs deliver the highest annual yield for typical UK domestic systems.
Midday production peaks can exceed daytime demand, so storage/export strategy is key.
This guide gives practical system sizing for a 4-bed home with realistic budget ranges.

System Guides

Solar Panels for a 3-Bedroom House with East/West Roof

East/west roofs produce less annual energy than south, but often match household demand better.
Broader morning/evening output can improve self-use and reduce import reliance.
This guide provides realistic sizing and expectations for a 3-bed east/west setup.

Solar Panels for a 4-Bedroom House with NW/SE Split Roof

NW/SE split roofs can still perform well in UK diffuse-light conditions.
Generation profile is flatter than south-facing, which can improve usable energy.
This guide maps practical system design for a 4-bed split-roof scenario.

Solar Panels for a 2-Bedroom House with South-Facing Roof

A south-facing 2-bed setup can deliver strong annual yield with relatively simple design choices.
Right-sizing inverter and battery is crucial to avoid overbuild or clipped value.
This guide provides realistic component ranges and expected performance outcomes.

Solar Panels for a 3-Bedroom House with North-Facing Roof

North-facing roofs can still work in the UK when system design is realistic and expectations are set correctly.
Annual yield is lower than south-facing, but diffuse light reduces the gap versus common assumptions.
This guide gives practical sizing and ROI framing for a 3-bed north-facing setup.
