NOTE
The “I
panel
” value varies depending on the type of solar panel installed. Refer to
the vendor’s specifications for the solar panel being used.
For example, if I
array
equals 0.54 amps, and I
panel
equals 0.29 amps for a 5-watt panel, then the number
of panels required equals 1.86, which would be rounded up to 2 (panels connected in parallel).
Alternatively, the next larger solar panel can be used, which in this case would be a 10-watt panel.
Table 1-2 gives I
panel
values for solar panels recommended by Fisher Controls.
