alt Hacker NewsAre you talking about rooftop solar?
For an 800W balcony system your background house usage is likely to be enough to self consume most of it.
You'd wouldn't be able to run even a small oil heater except maybe in peak summer.
It's a good match for working from home as it's a small amount of power spread over daylight hours.
There are a variety of small simple oil heaters in the UK under 800W. You're not going to heat a house with something like that, and obviously you'd be more likely to need one when it isn't sunny, but it seems the 800W balcony solar could run such an oil heater.
Yes it's probably more practical that it's powering your laptop and the coffee maker and that sort of thing.
