ᐅ Planning a Photovoltaic System – Is There a Tool Available?

Calculate the cost of the materials first.
Then calculate the cost of the scaffolding.
And finally, calculate what the three workers are paid for their labor over two days.

The installation costs are 2300 euros. It sounds like a lot, but it's actually similar across all quotes.

What is there to consider? The great new upcoming law from the current government coalition?

If you were familiar with our local conditions, the decision wouldn’t be so simple.

Which ones are those?

And yes, a heat pump operates most frequently during the periods when it is needed and the sun is not necessarily available. But currently, with the correct system size and a few adjustments, this only amounts to 2-3 months.

Please give a hint about which type of local condition influences this kind of decision. I can’t think of anything at all right now.

Sure. We have a mid-terrace house with two parking spaces right in front of the door. The entrance is directly at the house, and on both the left and right sides, there are two light wells for the basement windows. I once created a sketch, which I’m happy to share here. I am open to any opinions. In my view, the only possible location would be at the edge of the right parking space (the red area is where I could most likely imagine placing the heat pump). I would lose the parking space there. In fact, this was part of my plan because we would put a bike rack or possibly a bike shelter there.

However, that parking space has a slope—less steep on the right side than on the left. In winter, melting ice could create an icy strip there, which could probably be managed. But based on what I’ve seen with heat pumps, there is a risk that cold air could cause the area in front of the heat pump to freeze during winter. This would be the path someone walks when heading to the entrance. Of course, you can walk about 2 meters (6.5 feet) farther to the left, but there is still a risk.

Additionally, our current gas heating system is installed upstairs, so I would need to move everything to the basement and then install a riser pipe inside the house, since all water connections for heating and hot water are upstairs. So, it’s not that simple.
