Textbook Question
Chapter 2, Problem 67E
You have found a way to directly power your wall clock (consumes 0.5 mW of power) using a solar cell collecting ambient room light, rather than using an AA battery. The solar cell and battery each provide the required voltage of 1.5 V and the proper current for clock operation. Your solar cell has an efficiency of 15% and costs $6, and each AA battery has a capacity of 1200 mAh and costs $1. What is the payback time (point in time where the cost of solar cell would match the cost for supplying batteries) for using a solar cell instead of batteries?
