Case Study: Energy Self-Sufficiency for a Family in Kleinmachnow
Shadows on solar systems: How power optimizers can help
Let’s be honest: if the roof needs renovation anyway, it really is the perfect time to plan for a photovoltaic system. This not only saves renovation costs and time, since construction work is already underway, but also increases long-term energy efficiency and the value of the property – boosting the financial balance in the long run. Whether you choose an in-roof or on-roof system depends on the structural conditions and your personal preferences. Both have their advantages, so the decision should be well thought through. The big plus: you can prepare the roof directly for the entire lifetime of the solar system in Potsdam and benefit from a cost-effective, holistic solution. It hardly gets more efficient than that.
Why is this combination so worthwhile?
Efficient cost and effort optimization:
When roof renovation and photovoltaic installation are planned together, it saves real money. No duplicate visits from craftsmen, no unnecessary extra work. This significantly lowers overall costs and ensures a smooth process.
Long-term investment security:
Photovoltaic systems operate reliably for 30 years or more. If the roof is renewed at the same time, the entire structure is ensured to last for decades. No later need for renovation that could disrupt PV operations – this creates planning security.
Sustainable efficiency gains:
The combination of energy-efficient roof renovation and a modern PV system pays off: energy consumption decreases, operating costs go down, and the company positions itself as sustainable and future-oriented. This not only improves the financial balance but also enhances the overall image.
Roof renovation with photovoltaics – your options at a glance
On-roof installation:
In this method, the solar modules are mounted onto the existing or newly covered roof using a supporting structure. This solution is proven, economical, and adaptable to various roof types. Installation is usually straightforward and can be implemented quickly.
In-roof installation (integrated PV system):
With this option, the PV modules take over the function of roof covering and are integrated directly into the roof surface. This creates a modern, aesthetically pleasing appearance. In-roof installation is particularly suitable for new builds or comprehensive roof renovations, as it replaces tiles and allows for a seamless look.
The Key Steps – No Frills:
- Check the roof condition:
Start with a thorough inspection of the roof. Potential damage, renovation requirements, and the general condition are documented. This gives you a clear picture of what to expect and allows you to plan the next steps precisely. - Plan the PV system wisely:
The orientation of the roof is crucial – south, east, or west provide the best conditions. Shading and available surface area also play a major role in the system’s efficiency. Careful planning is recommended here to secure maximum output. - Research funding opportunities:
It’s worth looking into current subsidy programs at the federal, state, and municipal levels. Being well-informed can significantly reduce investment costs and speed up the payback period. - Hire professionals:
Rely on experienced specialists who can handle both the roof renovation and the photovoltaic installation. This ensures professional and efficient execution – and helps you avoid unnecessary complications during the project.
