Photovoltaic number cruncher
A solar calculator is a small electronic calculator powered by photovoltaic cells rather than batteries.
The solar panel converts ambient light into electricity, making the device functional indefinitely without battery replacement.
Most solar calculators include a small backup battery for low-light conditions.
I've had the same solar calculator on my desk for fifteen years.
