What is the minimum size for a solar folding roof?
The project should have a minimum area of 1,500 m². Care must be taken to allow distances of approx. 5 metres from buildings and public roads that do not count towards this area. There is no limit to the maximum size of the solar folding roof, as it is modular and can be scaled as desired.
What effect on the yield does retracting during storms, hail or snowfall have?
What is an ideal shape for a solar folding roof?
What is the service life of a solar folding roof?
The solar folding roof is designed for a service life of at least 25 years. A performance guarantee of 25 years is also given on the modules.
The supporting structure has a service life of 50 years. If the folding roof groups are exchanged, they can be placed several times on the same supporting structure.
What electricity production costs can be expected?
In the european midlands and in the pre-alpine region, production costs of 12-16 cents/kWh can be expected. This already includes the basic service contract and the amortization over 25 years.
How much service does a solar folding roof need?
How do I start a solar folding roof project?
You can create a non-binding initial assessment for the planned area online with the >SOLAR CALCULATOR. If required, we will contact you, clarify further details and offer you a preliminary study.
The comprehensive preliminary study includes binding information on
- technical feasibility,
- eligibility for authorisation and
- economic viability.
With the preliminary study dhp technology offers the solar folding roof at a fixed price, which makes budgeting reliable. Depending on the size of the project and the number of variants the costs for the preliminary study are between EUR 20,000 and CHF 30,000.
