This PV array was installed under a tree and as a result the branches of the tree were casting shadows on the PV modules.
Here the photovoltaic module is facing West and gets very little sunshine. In addition, a shadowing issue further reduces the output.
Bolts are not for current carrying. Bolts are to hold lugs, etc. in tight contact with electrical terminals.
During normal operation, water is lost from a flooded lead-acid battery as a result of evaporation and electrolysis...
