Our energy storage solutions have widened. First you timeshift all electricity use of the car, house or neighborhood into daylight hours when the sun shines. This means a bunch of electronics and software changes. Next we build termal storage solutions, you can store heat much cheaper than electricity. You move heat around with a heat pump. Or you heat your water tank with a datacenter computer in your water tank (for free). In summer you store solar electricity in ice. Or you store it in iron, aluminum, glass or silicon by melting ore and purifying, You embodied the solar electricity into the purified ore. In northern and southern latitudes you need 10 to 50 times more solar panels to heat houses during cold winters. This means you have large overcapacity in summer that you can sell as embodied iron, etc. Batteries are only needed to store for the hours there is no sunlight during 24 hours, no need to store longer. The cheapest place is to store it in the electrical cars in your neighborhood. That is why we install our own brand ev car chargers in the neighborhood of the panels. In contrast, Tesla chargers overcharge you a factor of 34 to 76 and that's partially because its fossil energy and transmitted over hundreds of miles.

My message is that to reach 1 cent per kWh we need to solar electrify all our infrastructure https://www.youtube.com/watch?v=iEOPx2X-EtE

Also Trump doubling solar panel prices with tarifs and shutting down subsidies is wrong, it makes it much more expensive. Add an oil third world war however does help, we sold double solar, batteries and evs in the last month.
