- 10kW or 13kW inverter
- ≈ 60 m²
What a 13.2kW system looks like

FAQ
System sizing, answered.
Send us a recent bill and we will tell you which of these is actually right for you.
Get a Free QuoteIt depends on your daily consumption and when it happens. A household using around 20kWh a day with most of it in daylight is usually well served by 6.6kW; heavy air conditioning, a pool or an EV typically pushes that to 10kW or more. We size it from your actual bill rather than guessing.
Roughly 2 square metres per panel, so a 6.6kW system with 15 panels needs about 30m² of usable roof, and a 15kW system about 68m². Usable means unshaded, structurally sound and on an orientation worth installing to.
You can, but it is rarely the cheaper path. Adding to an existing array often means a second inverter or a replacement, plus a second lot of installation and paperwork. If you expect your usage to grow, it is usually better to size for that now.
No. Beyond your actual consumption the extra generation is exported at a low feed-in rate, so the marginal return drops sharply. We will tell you when a smaller system is the better financial decision.
Tier-1 440W modules across the range, from Jinko Solar, Longi, Risen, Sunman and Boss Solar depending on availability and what suits your roof. The specific model is named in your quote, not left vague.
