A typical solar powered calculator

Solar powered calculators are hand-held electronic calculators powered by photovoltaic panels mounted on the device.[1] They were introduced at the end of the 1970s.[2]

Features Edit

Solar calculators utilize liquid crystal displays as they are power efficient and capable of operating in the low voltage range of 1.5 - 2 V. Features on other models includes a light pipe used to converge light onto the solar cells to power the calculator.[3]

Advantages Edit

  • Solar-powered calculators would be advantageous over conventional battery operated electronic calculator as the battery replacement need not be considered.[4]

Drawbacks Edit

  • Solar calculators may not work well in indoor conditions under ambient lighting as sufficient lighting is not available.[5][6][7]
