A couple of weeks ago my brother out of the blue had set up a solar-power system into our home. It is a system with one lead-acid battery and one solar panel and is good enough to power one electric fan in the day and basically unlimited light from an LED bulb which is only not more than 2 watts in its consumption.
You can see that there is a wall fan up there at the foot of my bed which is actually a 12-volt fan converted from being 220-volt electric-powered fan. But the LED bulb that I use here is very dim compared to my 220-volt electric powered LED bulb but it is a free power from the sun so at least the dimmer bulb gives an ample source of light, not my preference but it will do.
In the future I hope to upgrade this solar-powered system so that we could save some money from consuming expensive electricity. Being off-grid, meaning not using any electricity from the provider is the goal but I have to focus first on my medical needs and also hope that Cryptocurrency prices goes up so I can soon be able to achieve some of my goals.
