ᐅ Installing a Photovoltaic System with an Air-to-Water Heat Pump?

Hello everyone,

We recently purchased a house from the developer, and the selection appointment is coming up soon.
Basically, we plan to stick mostly to the "standard" options due to our budget.
The house is equipped with an air-to-water heat pump. In the special requests catalog, there is a photovoltaic system listed for 10kW.

As a layperson, I have the following questions:

- Should we have it installed? Will our electricity then be free in the future?
- How are these systems subsidized or supported?
- Does it make sense to install one?

Thanks in advance for your help.

How large is the system for 10k?

Based on experience, photovoltaic systems tend to be cheaper if offered separately afterward. However, it would definitely make sense to have some preparation included.

Funding cannot be answered in a general way.

Free electricity for the future? Probably not, if that was meant in general. The photovoltaic system produces a certain amount of electricity, which you will partly use yourself and partly feed into the grid (most likely for a small compensation). Or into energy sharing platforms—whichever you prefer.

However, with a photovoltaic system, you will probably not be able to cover your entire electricity demand.

You were the one with the tight budget and lots of worries. Just don’t take on any more debt.

Solar power almost always makes sense. Even more so with current electricity prices.
BUT: What do you get for $10k?

A photovoltaic system up to 5 kW can be cost-effective; beyond that, it is usually not profitable.
The key factor is that battery storage systems become more affordable, as current prices are generally excessive.
An exception is when an electric car can be charged to some extent. Otherwise, self-consumption often amounts to only around 25%.

An exception is if an electric vehicle can be partially charged. Otherwise, self-consumption is often only around 25%.

The feed-in tariff is expected to be significantly increased.
