I live in Germany, installed a micro solar system in September 2024. Since then, we've been producing 45% of our electricity consumption ourselves. This has saved us 550€, while the initial cost was around 800€. So this September, after 2 years, the system will have paid for itself.

Could you provide more details? 800 Euros sounds very cheap while being able to produce 45% of your electricity needs. Did you mount it on your roof or a balcony or wall? How much power does it produce? Very curious to hear more details or even recommendations (I too live in Germany).

Have a look here:

You still need attachment material for your balcony.

Keep in mind that this system will input all it's power into your power grid. If you don't use the power it will go directly into the public grid.

Still, really good cost saving measure.

Do you own one of these? If yes, are you happy with the quality?

No I don't own them. Some people here: https://www.mydealz.de/share-deal-from-app/2753917 mention as a downside that you have to connect to the manufacturer cloud to get the live production data from the interverter. Otherwise it is truly "plug everything together and it works".

Hi, sorry I'm late to respond. The price was something like this: 150€ Hoymiles HMS-800W-2t 300€ 4 Trina Solar 445W Full Black panels 100€ Shelly Pro 3em (not necessary but I wanted to see how much we feed in) The rest was construction materials and small stuff. We have mounted it on our roof, 900W East, 900W West. One east and one west panel are wired in parallel and connected to one MPPT of the HMS-800W. We're producing around 1.3MWh per year.

Crazy thing is, the cost of these systems has gone down even further since then. You can get a 800w plug-in solar set with panels and an inverter for around 200€. Shipping might be 70€ or you can pick it up locally at the dealer. Add another 50-100€ for attachment material and you are good.

So for 250 to 400€ you can get a system that will break even latest after four years, likely earlier.

Yes, although to be fair we have around 1.8kWp, plus roof installation material, plus shipping.
