You can get home batteries that will store the power generated by solar panels for use at night. You can go and buy one right now.

I don't know why you're quoting current figures like that's the maximum potential of solar when it's hardly used right now. The power output of an average home can be covered by about 15-20 solar panels, so just stick the fucking things everywhere then order a fuck ton of powerwalls off Telsa. Climate crisis solved. You're welcome, future generations.

Re: Winter. Solar panels work off light, not heat. It still gets light in the winter, although the days are shorter. However, winter conditions are better for solar as the panels are adversely affected by heat. So swings and roundabouts. We should probably have other sources to cover any shortfall by solar should be the mainstay.
