Balcony solar panels can save 30% on a typical household’s electricity bill and, with vertical surface area in cities larger than roof space, the appeal is clear
That won’t really work as that is the worst scenario for solar. I can give you real world data from southern germany. I don’t have balcony solar, but a 13,4kWp solar system on my roof. Here is the data from this year:
As you can see, days are getting longer in Feb, generation is going up. To get a rough estimate, take my data and divide it by 16,75. That won’t give you a lot of heating, esp. with a normal space heater. Even if you had a scenario, where your 800W solar system would produce 800W in the winter, your space heater will suck 2000W. Take a look at its power cord, you’ll see how much it uses.
So yeah, 800W is not much, but will cover your running appliances like your fridge, freezer, router or computer on sunny days.
Hey thank you! I’m definitely saving this off for my future calculations!
You’re totally correct about the rest, and I’m now able to roughly see if I should buy a 800 system or two, or theee… Electric hookups included in the calculation of course.
Be careful there - you’re pushing electricity in your grid and there is a reason why only one system is permitted in Germany. Don’t hook up two or three without talking with an expert.
