Case Study: Energy Self-Sufficiency for a Family in Kleinmachnow
Shadows on solar systems: How power optimizers can help
Combining a photovoltaic system with a heat pump creates an extremely efficient solution for the home. The PV system generates sustainable electricity, which the heat pump uses efficiently – reducing energy costs and increasing independence from energy providers. Of course, for optimal performance, an intelligent control system is required. A battery storage unit is also advisable, especially since the heat pump often consumes electricity when the PV system produces less. This maximizes self-consumption and ensures that the system operates economically and sustainably.
Advantages
- Optimized energy costs: The SG Ready combination of photovoltaics and heat pump clearly reduces energy expenses. Self-generated solar power significantly lowers the need for grid electricity, which is immediately reflected in ongoing costs.
- Sustainability impact: Both technologies rely on renewable energy and make a direct contribution to the energy transition, whether at home or in a business.
- Increased self-consumption: The PV system paired with a heat pump can be strategically used as a controlled electricity consumer, further boosting self-consumption. This means you use your own solar power even more efficiently.
- System flexibility: Whether retrofitting an existing system or installing a coordinated complete package, you have the choice and can adapt the solution optimally to your individual needs.
What to Pay Attention To
Sufficient roof space
For the combination of a PV system and a heat pump, a larger roof area is required to achieve the necessary output. The more module surface, the better the energy yield.
Optimal orientation
A south-facing roof is crucial for maximum electricity production. If your roof faces north, efficiency drops noticeably. Be sure to consider the correct orientation.
Home insulation and heating system
This combination is particularly worthwhile in well-insulated new buildings – ideally with underfloor heating or low-temperature radiators. This keeps heat demand low and ensures the system operates efficiently.
Battery storage
An additional battery is recommended to store solar power generated during the day for use by the heat pump in the evening or at night. This increases self-consumption and reduces grid electricity costs.
Intelligent energy management
An energy management system optimally coordinates electricity consumption. It activates the heat pump preferentially when sufficient solar power is available – reducing reliance on grid electricity sustainably.
Economics and costs
The initial cost of a heat pump with solar is noticeably higher than individual components – that cannot be sugar-coated. However, attractive subsidy programs can significantly reduce the purchase cost, especially for the heat pump. In the long term, this investment pays off through substantial energy cost savings. Any excess electricity produced can be fed into the grid, generating additional income.
