ᐅ Gas Prices – Where Is Gas Still Affordable?

No VAT, you get it back. I have the impression that you have heard or read a lot, but you haven’t fully understood this (admittedly) complex area. (P.S. I haven’t understood everything 100% myself either)

Please, just create a scenario for yourself, your house, and a hypothetical photovoltaic system. We’ll gladly calculate it as honestly and transparently as possible for you.

That may be true. After the first offer, I considered it uneconomical for me, but I only did a rough calculation.

But this complexity already deters many people. Why can’t all this tax stuff be simplified or waived for private individuals?

What information do you need?

You are right, the politicians (the ones WE elect) should have made this much simpler. I completely agree with you!

When planning a photovoltaic system, some basic data is needed first, because the larger the system can be, the more cost-effective the installed kWp on the roof becomes.
Since one-time costs (planning, scaffolding, connection to the electrical system, etc.) only occur "once."

So we need information about all roofs (roof pitch, size, orientation, obstructions such as chimneys, trees that could cause shading, satellite dishes, ventilation pipes, etc.).

Photos of all roof areas with drawn measurements including any outbuildings (garage, carport) are also welcome.

Then the location (postal code) to roughly calculate the system with PVGIS.

Next, a trial version (30 days) of Photovoltaic*SOL to design string layouts, select a suitable inverter, etc.

Once the hypothetical system is put together, unfortunately, it moves into the real world to collect quotes. Which is currently anything but fun.

With modules and inverters, you are unfortunately left with some improvisation, but hopefully better times will come again?

Let’s do it this way until then, and we’ll see how it goes... We would be happy to receive some support from people who are even more experienced in this topic 😉

Best regards

After that, a trial version (30 days) of Photovoltaic*SOL to figure out strings (wiring), suitable inverters, and so on.

Once the hypothetical system is assembled, unfortunately you have to deal with the real world to get quotes—something that is anything but fun right now.

With modules and inverters, you probably have to improvise a bit, but hopefully better times will come?

Okay. Now we’re back to the complicated issue. I would expect all of that from the solar installer.
Honestly, after our house build, I don’t feel like getting deeply involved with the next topic.
I also thought you wanted to roughly calculate it once.
So let’s stick with my current plan: in 4 to 5 years, we will need a new car. Then I’ll calculate again; maybe it will make sense then, especially in connection with an electric vehicle. Maybe there will be new modules and other components by then as well.

Hi Silke,
no, really not complicated ;-)

You just provide roof areas, preferably with photos and approximate dimensions, rough orientation, and approximate roof pitch (30, 45°?).
I’ll take care of the rest (we will).

But of course, if you don’t have around 20,000 (I don’t right now either!) you’ll need financing. You have to want that, even if you think of it like investing in a stock with a government-guaranteed dividend (e.g., telecom, 4%). If you come out ahead after 20 years, that’s a nice surprise. Especially if the monthly payment is lower than the monthly savings.

If you’re ready, I am ;-). Otherwise, of course, it’s perfectly possible to live a fulfilled life without photovoltaic solar! I managed 53 years just fine 😉

That sounds much simpler 😉. Thanks for your offer. Let’s wait until next year when the situation has settled down again and we are both still here, then I’ll get back to you 😉.

Let's do this in a separate thread then.

Just a quick note for @motorradsilke: It really works, and you can calculate it very, very accurately in advance. I have access to (though I don’t own all of) 7 photovoltaic systems. The oldest is 19 years old, the youngest 11 months old. All of them, even those not facing south, have so far met their projections and have been more than cost-effective.
