Residential
Your roof, at its full potential.
Systems designed around the property — roof structure, shading, real consumption. Battery-ready as standard.
Solar, engineered.
Designing solar PV and battery storage for the way you actually use energy.
Battery
Store the sun.
Spend it later.
Time-shift generation, cut peak-rate imports, keep the lights on when the grid blinks.
Commercial
Bigger roofs.
Better numbers.
Warehouse, farm and light industry systems modelled on your half-hourly data.
How it works
Every kilowatt-hour, accounted for.
Sun to panel, panel to battery, battery to home — with export to the grid when there's more than you need.
Numbers, unprompted
A conservative estimate in thirty seconds.
No forms. No email. Adjust system size, storage and bill to see roughly what a Lumera-designed system could do.
Savings estimator
A rough figure before we survey.
Move the dials to see roughly what a system might do. Real numbers come from a site survey — this estimator is deliberately conservative and uses public assumptions listed below.

- Generation:

- Import rate:
- 26p/kWh — indicative 2026 rate, verify with your supplier
- SEG export rate:
- 12p/kWh — indicative 2026 rate, verify with your supplier
- Self-consumption:
- 75% with a battery — 3,206 kWh self-used, 1,069 kWh exported
- Household usage:
- £1,680/yr ÷ 26p/kWh ≈ 6,462 kWh — self-use is capped at what you actually consume
- Payback:
- £11,175 indicative install cost ÷ £962 first-year benefit
