Educational guidance only, not advice for a specific home. File 01 - Home energy performance foundations Setting a Performance Baseline How to record a home's starting point, using certificates, meter readings and simple observations, so later improvements can be judged fairly.

Educational only, not advice for a particular home. File 07 - Solar panels and storage Solar Battery Sizing How to size a home battery to evening demand, solar surplus and tariff structure, rather than to roof size or a round number.

Educational only, not advice for a particular home. File 07 - Solar panels and storage Solar for North-Facing Roofs When solar can still work on a north-facing roof, what output to expect, and when another roof, a shared array or no solar is the honest answer.
