I want run some devices off the grid for lower electricity bill and to learn about off grid systems so as to live fully off grid some day.Comment

most people here don't even try to use solar energy because of the long term investment. Net metering has more fans.
But I believe that living in a country with 300+ out of 365 days full sunshine is a pitty to don't even try to reduce electrical bill or to run devices when there is black out. Investing money to 8+ year lifetime equipment can pay you back. This is my first milestone.

I live in Greece and the monthly electrical bill is around 100 Euros (almost 100 dollars).

While the price of a solar/battery system has come down the price range is somewhere between $1500 to $2000 for each kWh a system can safely produce. So if you use 10kWh a day you might be looking at $15000 to $20000 just to install a working system. Then after a few years the batteries wear out and you need to replace them adding to the original cost.
Until battery prices come down you end up paying a lot just to run your basic "comfort" loads. If you just want to use the system to power small watt loads or shift your usage to a time when the POCO charges you very high prices it can be hard to justify going off grid.
Try to determine what loads you really need to run off the battery system before you purchase anything. That way you won't be wasting your money by building an inefficient system.Comment

Folks around the Mediterranean (and particularly Greece) have been meeting a lot of their energy and lifestyle needs quite elegantly for millennia without PV.
If it was me (and it sure ain't), I'd have started with a goal of only using electricity for tasks that cannot be done any other way. I can heat water with the sun, or even natural gas more effectively and probably cheaper than PV, but it's tough to run the computer screen I'm looking at (or the one you're reading this from) with natural gas or firewood.
Q: What's your annual electrical usage in terms of kWh ? Do you know ?Last edited by J.P.M.; 12-21-2019, 11:33 AM.Comment
