Yeah. Solar-thermal technology was definetly doable with off the shelf components of the mid-late 19th Century, unfortunately coal and oil were cheaper and just as easily available.
But if you're stuck in the tropics where coal isn't available and before oil is begin widely used, your only choice would be solar energy. And once you start refining solar-thermal technology to improve efficiency and start coming up with other ways to use it, I feel like it would create a positive feedback loop that could lead to running industry based on a practically infinite source. Imagine where we'd be if we had started seriously investing in solar energy in the 1800s.
