How is a photovoltaic system sized for a home or business?
Sizing starts with annual electricity consumption in kWh from utility bills, hourly usage profiles, and roof orientation and shading. Residential systems often range between 3 and 6 kW, while heat pumps, electric vehicles, or commercial loads require tailored higher capacities.
When does battery storage make sense?
Battery storage increases self-consumption by storing daytime solar electricity for evening and nighttime use. If backup power during grid outages is required, a dedicated inverter and backup circuit configuration must be specified.
Are tax incentives available for photovoltaic systems in Italy in 2026?
Yes. For eligible residential installations in 2026, Italian tax deductions provide 50% recovery for primary residences and 36% for other residential properties over 10 years, up to a €96,000 expenditure cap.
