Photovoltaic panel water tank

Does a photovoltaic system have a heat fluid circuit?

Unlike solar thermal systems, photovoltaic systems do not have a heat fluid circuit. Here, power cables transport the energy from the solar module to the hot water storage tank. PV system owners need neither pipes nor pumps for this. So they don't have to worry about antifreeze or maintenance costs either.

Can photovoltaics make hot water cheaper?

Today, you can prepare your hot water much more cheaply with photovoltaics than with a comparable solar thermal system or with conventional heating systems. Our principle enables you to make the best possible use of your self-generated solar electricity in your own household.

How does a photovoltaic system differ from a solar thermal system?

Photovoltaic systems are less complicated and require less maintenance than solar thermal systems. Unlike solar thermal systems, photovoltaic systems do not have a heat fluid circuit. Here, power cables transport the energy from the solar module to the hot water storage tank. PV system owners need neither pipes nor pumps for this.

How much electricity does a photovoltaic system use?

Depending on the size of the photovoltaic system installed, an average household uses no more than 30% of its own photovoltaic electricity. However, if you use excess solar power to produce hot water, less electricity goes into the grid and you can increase your self-consumption to around 70%.
