System PP – an innovative, pressureless system

There are only a few systems on the market that function perfectly without antifreeze and unnecessarily high system pressure. Our pressureless System PP closes this gap. It includes KE 1 solar collectors and the PP storage tank.

Photovoltaics

We advise both builders and construction partners on photovoltaic systems. The first step is to select the appropriate technology. In addition to an energy-efficient product, we find the right dimensions for your system. The subsidies provided by the canton and the grid connection are crucial for financing and economic efficiency. We calculate the yield forecasts and assist you with the KEV registration.

• Control and battery storage

Cantonal subsidies

The construction of a photovoltaic system is supported by the canton through the cost-covering feed-in tariff (KEV). The KEV covers the difference between production costs and market price and guarantees producers of renewable electricity a price that corresponds to their production costs. The remuneration period is twenty years, and the remuneration rates are adjusted on an ongoing basis.Due to very high demand, there is a long waiting list. For small photovoltaic systems (from 2 to 30 kilowatts), a one-time subsidy can be applied for. New systems can be registered with the national grid company Swissgrid. We are happy to help you.

Calculation tools

Swissolar's solar roof calculator provides initial guidance before planning and installing a system. The Swissolar cost calculator can be used to determine the economic viability of a photovoltaic project. You can find more tools here. Of course, we will provide you with a precise calculation for your system.

Solar filling stations

Do you already drive an electric vehicle?

How clean an electric vehicle is on the road depends heavily on how the electricity was produced. Solar charging stations are worthwhile wherever there is enough time to recharge

– for example, at home or at work. The photovoltaic system on the roof is combined with a charging station. A combined system is already financially attractive for private individuals and companies today.
