About a decade ago I was woking on a project to run a network of instruments in the Arctic that needed to run over the polar night, powered by batteries charged by wind and solar.
So what type of battery was finally chosen?
Where were the instruments placed?
We tried two options, Deka AGM, and Saft Lithium Ion with super-capacitors for load leveling. Both worked well, but the lithium ion was about 1/10 the weight which saves a huge amount on aircraft costs.
Stations were installed around Summit Camp in Greenland.
