> The challenge is making solar panels that are cost effective (e.g. $ per Watt).
And the other key challenge is nighttime.
If we had relatively low-cost utility-scale electrical energy storage, we would see a much higher rate of solar energy adoption. More so in sunny places, but that would then drive down the cost for everyone.
I keep hoping something like a flow battery will turn out to be practical, where to size up the storage, you just need bigger storage tanks.
