Mount the Board in the Mini Pump House
Then I can mount this on the back wall of the box and connect the battery terminals. I designed this rainwater harvesting system with room for expansion.
The 12V pump I have won’t draw a lot of amps so for now a single 100 watt solar panel will work for this system. The roof of the pavilion is sloped to the south and the pump will only be used in the summer months when there’s a lot of sun.
The Solar Panel
The kit comes with roof mounting brackets.
And they are attached to the panel with nuts and bolts.
To protect the panel while I’m handling it I’ll cut some cardboard and tape it to the face. And this will also prevent any shorts or sparks from the wires if I accidentally cross them. I’m not sure if I needed to do this. But, it can’t hurt.
Mount the Solar Panel
On the roof of the pavilion I’ll set the panel in place and check that the feet of the brackets sit flat between the ribs.
Looks like it just fits.
I cut a strip of Eternabond tape and stick it to the roof under the brackets. This should make a water tight seal. And the roofing screws have a rubber washer too.
Now I can drill two holes in the roof for the panel wires.
These wires will run through a water tight housing that I’ll silicone to the roof.
I’ll tape that in place while the silicone cures. Then connect these wires to the panel and tuck the connectors up underneath.
