ᐅ New Build Photovoltaic System for Semi-Detached House – Quote Comparison

Hello everyone,

I am about to build a semi-detached house (11.50 x 10 m) with a 45-degree pitched roof, no dormers, oriented north-south (meaning each roof half faces west and east respectively).
I have received three quotes for photovoltaic systems, with capacities of 10.8 kWp, 14.0 kWp, and 18.0 kWp, and to be honest, I’m not sure what I actually need or what would be sufficient.
Since my budget is limited, I don’t want to oversize the system unnecessarily.
All three systems include a battery storage unit, with the 18.0 kW option specifying a usable battery capacity of 9.60 kWh.
The household consists of one person plus a small business, and there is a heat pump with underfloor heating installed.

Can someone advise me on what size system I really need and what would be enough? When I ask the photovoltaic companies, of course, each one just recommends what they want to sell.

Best regards,
Flo

My system, 7.2 kWp with a 10 kW battery storage, costs 1500 euros per kWp. So, including the storage.

It shouldn’t cost much more than that. And yes, profit comes from purchasing wisely.
