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.
