Not quite. It's a solar thermal (heat generator) that feeds a heat storage facility via an air-flow heat exchanger. That exchanger can alternatively be fed hot air generated using any other technology, including burning fossil fuels.

So, the heat storage facility is "source neutral". In addition, precisely how the stored heat is used "downstream" is also not a central part of the design, but turbines etc. are a likely option.

I was picturing a solar-charged battery running a light above the panel overnight
