Three Scenarios, Three Paths to a Solar Heat Pump
There are three systems that efficiently connect a photovoltaic system with heating. A well-considered energy management can act like an energy storage and increase self-consumption.
For starters, there are various options: simple relay controls, smart grid interfaces, or centralized energy management. A targeted selection of controls enhances benefits and significantly reduces investment costs.
- Relay control for an easy start
- Smart grid interface for flexible operating times
- Centralized energy management for comprehensive control
Cantonal and state funding can significantly reduce investment costs.
Why the Combination Lowers Your Electricity and Heating Costs
By using self-generated solar power for the heat pump, the demand for grid electricity is significantly reduced. State funding makes it easier to get started and lowers overall costs.
Those who replace their old oil heating with this combination can benefit from higher self-consumption and reduced operating costs.
Grants reduce investment costs and support the transition to renewable energies.
Air-to-Water and Geothermal Heat Pumps: How the Technology Fits with PV
Air-to-water and geothermal heat pumps are ideal partners for photovoltaic systems because they efficiently use the generated electricity.
An additional storage can further increase self-consumption by storing excess electricity and releasing it when needed.
The right storage choice maximizes self-consumption and minimizes grid loads.
Market Prices, Funding, and Investment for the Overall System
The financial benefits of a photovoltaic-heat pump combination result from lower grid dependency and attractive funding.
Cantonal and state funding reduce acquisition costs, while tax incentives further lower the annual burden.
Careful planning ensures financial advantage through grants and tax deductions.
Amortization: Rising Electricity Prices Bring Break-even Forward
A reliable profitability analysis shows that rising electricity prices can bring the amortization point forward.
Photovoltaic systems offer protection against price increases and can become profitable faster with state grants.
When the Combination Is Not Worth It for Your Home
For unrenovated old buildings with poor insulation, combining photovoltaics and heat pumps may be uneconomical.
Additional costs from structural measures and lack of funding opportunities can impair profitability.
With poor structural conditions, a thorough evaluation is needed to ensure profitability.
Five Steps to System Integration with Predictable Yield
Strategic planning and professional installation ensure maximum yield from the photovoltaic-heat pump combination.

Frequently Asked Questions
How does a photovoltaic system work in combination with heating?+
The system produces its own electricity, which your heat pump uses for space heating and hot water, increasing self-consumption and reducing grid dependency.
How does the investment pay off financially for me?+
Your savings come from increased independence, grants, and lower energy costs, making the investment particularly profitable.
What grants can I apply for my project?+
In Switzerland, there are cantonal and state funding programs that can significantly reduce your acquisition costs.
Does the performance of solar modules remain stable over the years?+
Modern solar modules have low performance loss and are backed by long-term guarantees.
