Living off the grid. Never paying for electricity and rent again. This is the dream of many of our homebuilding families. We always recommend including a photovoltaic system. Clean electricity is definitely a great benefit—especially when it is self-generated.
Of course, adding a photovoltaic system increases the overall budget for your home construction project. In the long run, it pays off. But is that really the case?
What has been your experience? Are you truly living energy self-sufficient?

Of course, that's possible. The €600 is real. If he didn't have the photovoltaic system, he would have to pay €600 more on his electricity bill. However, if he didn't have the photovoltaic system, he wouldn't receive €900 either... You just can't mix up savings and actual payable euros.
The fact is: At the end of the year, €500 have to be paid. No sign of zero energy costs...
And if he pays 500,- with photovoltaic panels and we, my wife and I, pay 850,- without any photovoltaic system (even with a washing machine, dryer, dishwasher, and we don’t sit by candlelight either, and she also cooks), how is such a photovoltaic expert ever going to be profitable?
However, the comparison doesn’t say anything meaningful. What really matters is the comparison of Mastermind "without" vs. "with." Without, he would pay €2000 (about $2,200) per year for electricity; with, he pays €500 (about $550). This means he effectively saves €1500 (about $1,650) per year, not considering taxes and interest (either loan interest paid or lost interest on savings). Including these factors, the savings are somewhat lower. Depending on the initial purchase price, I don’t find that too bad…

Mastermind110 May 2018 21:48Do you calculate this way when building a house, even when using better insulation or a more efficient heating system? With that mindset, it will be a tent with an open fire ;-)
You can also calculate only with the feed-in tariff, then the ROI is just under 10 years. After that, you still have another 10 years of feed-in payments, which will bring it into the positive :-)

cybergnom10 May 2018 21:51I exclude the initial purchase cost completely anyway.
But when someone here says that you can achieve zero energy costs with a photovoltaic system, that's simply not true.

Mastermind110 May 2018 22:01Everything in my home runs on electricity. That’s why the electricity costs might seem relatively high.
However, these costs cover all expenses for heating, hot water, and household electricity.
In your case, I assume that on top of your €850 electricity bill, you still have €500–800 in heating costs, for example, from gas, oil, or pellets. Depending on the size of your solar photovoltaic system, your income from it could indirectly cover your heating costs.
