How Efficient Are Solar Panels On Mars

Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity.

How efficient are solar panels on mars.

High quality solar panels can exceed 22 efficiency in some cases and almost reach 23 but the majority of photovoltaic panels available are not above 20 efficiency. 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. 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 efficient solar panels. Solar panels have been consistently increasing in efficiency at about 5 annually since 2010.

This means that martian solar panels at max would be around 1 3 as efficient as their most efficient counterparts on earth. Solar cell energy conversion efficiencies for commercially available multicrystalline si solar cells are around 14 19. Like any space travel endeavour efficiency is paramount. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range.

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. 4 the comparison between solar panels on mars and solar panels here on earth is quite similar. Let s estimate that mars base one will require 10 000 kilowatts of power. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency.

Hopefully by the time we launch to mars we ll have some even better solar panels. Most solar panels are between 15 and 20 efficient with outliers on either side of the range. Missions to the surface of distant planetary bodies require power lots of power. 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.

This figure better accounts for dust storms variations in orbital distance martian tilt etc.
