How Efficient Are Solar Panels On Mars

Through the 2018 breakthrough innovative and game changing big idea challenge nasa is enlisting university students in its quest for efficient reliable and cost effective solar power systems that can operate on mars both day and night.

How efficient are solar panels on mars.

These robots were able to perform better than expected because quite simply strong winds on mars vacuumed up the dust that had settled on their solar panels which gave them a 70 boost in power efficiency. So if a solar panel has an efficiency rating of 15 that means 15 of the sunlight that hits the solar panels will be converted into electricity. This means that martian solar panels at max would be around 1 3 as efficient as their most efficient counterparts on earth. Some can get as high as 25 or 35 but most are in the 20 s so we ll say that our solar panels have 20 efficiency.

Solar cell energy conversion efficiencies for commercially available multicrystalline si solar cells are around 14 19. Solar cell efficiencies vary from 6 for amorphous silicon based solar cells to 44 0 with multiple junction production cells and 44 4 with multiple dies assembled into a hybrid package.

Most solar panels are between 15 and 20 efficient with outliers on either side of the range.

Factors that affect solar panel efficiency. Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity. 4 the comparison between solar panels on mars and solar panels here on earth is quite similar. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency.

This figure better accounts for dust storms variations in orbital distance martian tilt etc. Like any space travel endeavour efficiency is paramount. Hopefully by the time we launch to mars we ll have some even better solar panels. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range.

Most efficient solar panels. Let s estimate that mars base one will require 10 000 kilowatts of power. Missions to the surface of distant planetary bodies require power lots of power. An average solar panel will have an efficiency of 20.
