THE BUILD SHEETS
Systems sized from meter data, not roof guesses.
Every quote starts with twelve months of your meter data. We size the array to what you use, not to what fits on the roof. Three builds cover most homes. The full sheets are below.

Price the three-phase buildSTORAGE, HONESTLY
When a battery earns its keep
IT EARNS ITS KEEP WHEN
- Evening use above 12 kWh a day
- Export capped at 5 kW by the network
- Outages you want to ride through
- A feed-in tariff that pays little
SKIP IT WHEN
- Most power used while the sun is up
- A generous feed-in tariff
- Budget better spent on more panels
We model both cases on your meter data and show the arithmetic either way. If storage does not pay back inside ten years, we say so.
STRAIGHT ANSWERS
Questions from the quoting desk
What if my roof is shaded?
Shade costs yield, not the whole system. We model it panel by panel from satellite imagery and a site visit. If the numbers fall short, we tell you before you sign.
Do you install on tile and metal roofs?
Yes. Terracotta, concrete tile and metal sheet. Tile roofs take a little longer and the sheet says so. Every penetration is sealed and photographed before panels go down.
What is the export limit?
Most homes can export 5 kW per phase. The inverter is set to the limit the network approves. Storage soaks up what the grid will not take.
Do panels need cleaning?
Rain does most of the work. In dusty spells a rinse once a year holds yield within a few percent. We clean installed systems at cost.
What does the warranty cover?
Panels carry 25 years on output. Inverters carry 10. Our workmanship carries 10. One phone number handles all three.
How long does install day take?
One day for most homes. Two for tile roofs and three-phase builds. The power is off for about an hour while we commission the system.
