I ran over one of my solar yard lights. The solar cell is fine. What can use it for? It's about 2 inches x 2 inches?

you can use the circuit as is mod it into a solar charger to charge batteries use the led for a led project use the LDR (light sensor) for another project
Depending on the voltage output, you could make a solar roller (Google it) or a solar submarine (look it up on Intructables). There are many other projects if you search the Internet.
