Solar energy experts discuss PV technology and system sizing

Solar energy experts are highlighting key considerations for homeowners investing in photovoltaic (PV) systems, focusing on safety, technology, and optimal sizing.

PVT-Schweiz GmbH, based in Herisau, emphasizes the importance of fire protection and long-term reliability. The company utilizes Enphase technology, which employs microinverters to operate without dangerous high-voltage direct current on rooftops. Their approach integrates premium European products, intelligent energy storage, and monitoring systems to ensure investment security.

Regarding system capacity, expert Peter Bachmann notes that the ideal size of a PV installation depends on household electricity consumption, usable roof area, orientation, and potential shading. While a 7 kWp system may suit a household consuming 5,000 kWh annually, Bachmann recommends maximizing roof coverage due to falling module prices and the increasing energy demands of electric vehicles and heat pumps.
