1. Roof rental for homeowners

Everyone knows that you can rent out your own home. But many owners are not even aware that renting out the bare roof area can also be an option. Especially those who cannot invest in solar systems themselves or simply have an incredible amount of space available can earn money in this way and enable another person to invest. If it comes to letting, both parties benefit – right?

1.1. Is roof rental worth it for tenants?

Especially now, when more and more private individuals are becoming aware of the possibility of renting a roof, the prices for feeding in solar power are falling. Around 15 years ago, the feed-in price was just under €0.50 per kilowatt hour – usually even with a fixed price for twenty years. Investors who had to rent roof space could still benefit from renting out their roof despite paying rent.

Today it looks a little different: The average prices for feeding in solar power from photovoltaic systems are currently between €0.07 for large systems and €0.09 for average-sized systems. So investors get less money for their electricity. However, one must not forget that the Acquisition costs for solar systems have fallen significantly in recent years. The energy-generating panels on the roof therefore pay for themselves more quickly, or even pay for themselves with lower income from the feed-in.

If you are interested in renting roof areas, you should contact an expert for a precise calculation. In this way, it can be determined whether the investment in rental roofs and photovoltaic panels pays off.

1.2. Is roof rental worth it for landlords?

If you have a roof area that is not used by your own systems, you can assume that the rental concept is worthwhile. This is especially the case if you can not only rent out small roof areas on your own residential building, but large areas. So this is particularly interesting for farmers with large stables that offer roof space. However, owners of large warehouses or industrial halls in particular can benefit financially from renting them out.

2. The size of the roof area is crucial

Depending on the size of the home, the average roof area is 30 to 70 square meters. However, renting a roof is only considered to be really economical from an area of ​​around 600 square meters.

3. Remuneration for roof rental

Anyone who has a sufficiently large roof area that can be offered for rent should of course also know what income can be expected from the rental. As a rule, a distinction is made between different remuneration models if you want to rent out roofs:

3.1. single payments

Solar systems are long-term investments. For this reason, the one-off payment has established itself as a remuneration model for rentals. The tenant pays an amount, usually between €4,000 and €9,000, to the landlord, which is intended to cover a period of twenty years.

3.2. Annual Compensation

The annual rental of roof space is a flexible model where the remuneration can be based on either a profit share or a flat rate. An annual sum is common for profit sharing, which usually amounts to 5% of the profits. This method adapts to the pricing of the feed-in every year.

In the case of flat-rate billing, the amount of the remuneration depends on the size of the roof area: landlords can post income of between €2 and €5 per square meter.

4. Case-by-case advice necessary

If you are toying with the idea of ​​renting out roof areas, you should carry out a case-by-case assessment with an expert. This is the only way to determine how high the possible income from renting would be or whether it should beown investment in solar panels could be more lucrative in the long term.
