4 SOLAR PANEL INSTALLATION
4.1 L OCATION
Determine a location for the solar panel that is in direct sunlight and clear of any shading by adjacent obstacles
such as trees, roof overhangs, etc. Ideally, the panels will be positioned to minimize the wiring distance between
the solar panel and the charge controller and will have sufficient space to access the panel for servicing should
it be required.
For Northern Hemisphere installations, the solar panels should be mounted at angle facing true south (true north
for Southern Hemisphere installations). The mounting angle should be equal to the latitude location of where
you are installing the solar panels. For example, the latitude of Miami, Florida, USA is 25 degrees. Therefore,
solar panels installed in this area should ideally be facing true south at a tilt angle of 25 degrees.
Due to design constraints in many installations, you will not be able to mount the solar panel facing true south at
the ideal tilt angle. In these cases, try to come as close as possible to the ideal mounting configuration as this
will maximize the power output from the solar panels.
For Northern Hemisphere installations, face the solar panel true south at a tilt angle equal to the
geographical latitude of where the solar panel is installed.
4.2 12 OR 24 V OLT B ATTERY C HARGING
All of Windy Nation’s Complete Off-Grid Solar Kits can be configured for 12 volt battery bank charging. Windy
Nation’s Complete Off-Grid Solar Kits that contain an even number of solar panels can be configured for 12 or
24 volt battery bank charging. See Table below:
Size of Solar Kit # Solar Panels Included Battery Bank Compatibility
100W One (1) 12 volts
200W Two (2) 12 or 24 volts
300W Three (3) 12 volts
400W Four (4) 12 or 24 volts
Wiring diagram instructions on how to wire the solar panels in each kit for 12 or 24 volt battery charging are
shown in
