Climbing the #EnergyAccess ladder at a Finnish #offgrid summer cottage:
The first PV panel 15yrs ago was 40W and ok for phone charging and 2 LEDs (tier 1)
The current 160W panel has been ok for using a laptop for several hours a day (tier 2)
Now I brought two additional 400W panels in order to power a fridge (tier 3).
A new battery might not be necessary if I keep the thermal mass inside the fridge high with water bottles etc and install one of the new panels towards east and one west.
