How air-conditioning created the modern city

Supposedly photovoltaics are cheap enough thanks to scale that photovoltaic plus electric water heater is more cost effective than solar water heating.

And we can't really call solar panels "energy neutral", whatever they drive is still part of our energy consumption and their electricity could have driven another load.

I find this surprising.

A group of panels, install costs, wiring, an inverter, is less expensive than the alternative?

Volume, baby.

Solar hot water was never trivial either.

And don't forget about electric heat pump water heaters.
