☀ Use more solar power
Instead of feeing surplus solar power into the grid, use it yourself to produce hot water. You therefore reduce your energy costs.
☀ Protect the heating system
You extend the service life of your heating system because you can switch it off completely in summer. This also saves you money.
☀ Be independent and protect the climate
Make use of your own clean energy supply.
The electricity that you produce on your own roof is far cheaper than electricity from the grid. In order to permanently reduce energy costs, you should therefore use as much self-generated solar power as possible. Depending on the size of the system, an average household uses 20-40% of its own solar power.
By using surplus solar power for hot water production or heating, you feed less electricity into the grid. This allows you to increase your degree of self-consumption to over 60%. You give away less of your own PV power, have to purchase less energy from the public grid and save money.
Whether you heat your home with a heat pump, a pellet heating system, with oil or gas - a photovoltaic system can support the heating system. Whenever there is a surplus of solar power, it can be used to generate heat.
This option even allows you to switch off your heating system completely during the summer months and you do not have to activate the entire heating system for small amounts of hot water. This not only reduces your energy costs, but also extends the service life of your heating system
With the free Fronius Solar.web monitoring tool, you can keep an eye on your energy yield and consumption at all times and get the most out of your photovoltaic system.
“Until a few years ago, we used the heating system only to produce hot water from April to October. However, we can also do this with solar power and switch off the heating system completely during the summer months.”

A photovoltaic system generates green, cost-effective electricity. In order to be able to use as much of the self-generated solar energy as possible, a well-designed photovoltaic system and clever energy management are required.
Fronius offers you both. On the one hand, Fronius Solar.web is a clearly structured online tool that helps you to understand and optimise your energy flows.
On the other, you benefit from our large network of well-trained, certified partner installers.
Our Fronius System Partners offer you individual and expert advice and continue to be there for you even after your PV system has been installed.
