Product description
The solar panel has monocrystalline cells which generate
electricity when exposed to light.
Installation
Note:
As soon as thesolar panel is exposed to light or sunlight,
theMC4 cables will be live. This is especially important to
remember when you are connecting several solar panels
together. To avoid short circuits when assembling and
connecting solar panels, turn them away from thelight or
cover them so that they are not producing electricity during
theactual connection procedure. Remove thecovering when all
theconnections have been made.
• Always mount thepanel on astraight, flat surface; do not
bend or twist thepanel.
• Never attempt to divide or disassemble thepanel.
• Avoid drilling or welding theframe wherever possible.
Drill or adapt thefastenings instead.
• Do not use any sharp metal tools or anything else that
could scratch thesurface of thepanel.
• Install thepanel horizontally or vertically with theconnection
box at thetop. The solar panel should be facing south and
at anangle of 30−40˚ (summer), 0−20˚ (winter). Bear in mind
that if thesolar panel is in theshade, its power output will
drop considerably. Choose alocation for thepanel with as
little shade as possible. Use stainless steel fasteners to attach
thepanel. For easy installation, use theClas Ohlson solar
panel frame (sold separately).
Connection
To connect 2 solar panels in a12 V system: Connect them
in parallel by connecting thepositive to thepositive and
thenegative to thenegative terminals.
To connect 2 solar panels in a24 V system: Connect them
in series by connecting thepositive terminal of one panel to
thenegative terminal of thenext panel.
