50W panel mounted in obscure part of the side yard
|
Two 75 Watt LED strip floods
mounted behind fascia illuminate the patio |
Final checkout and hookup at solar panel.
The idea was to run the yard 3Volt LED landscape lighting and a
couple of LED patio floodlights off of a medium sized 50W solar panel and
a good quality battery pack. The Landscape lighting had to be photocell
controlled and the voltage had to be regulated 3Volts

Battery Box
Two Li-ion motorcycle batteries connected in parallel and a 10Amp fuse |
Original idea
Was to keep the battery box near the solar panel
Bury the wires and half the box
|
30 ft wire-run to junction box
12Ga heavy duty direct-bury landscape wire
|
We looked at mounting the panel at an angle and then
settled on a vertical mounting on the concrete wall.
It seemed easier
and more trouble-free

Ace Hardware
sells these nifty concrete anchors with 1/4-20 threads |
Original idea
Outdoor-type battery box with the solar controller
mounted in the lid
It was decided to move the battery pack and controller 30 ' and nearer to the load and
take the "hit" on solar charging current.
|
Configuration 2
Solar controller and 12V distribution in upper half of pool power panel.
Note the 3 Volt voltage regulator and photoelectric switch for landscape
lighting upper right
It's not good practice to do this so we were careful to make sure low
voltage wiring is strictly separated into the upper half of the panel

Battery box with in-line 10Amp fuse
sits behind pool electrical box |
Final mounting scheme
Has full sun for 8hrs/day

Schematic Diagram
|
Pair of automotive strip-type LED floods
These two pulled 3.5 Amps and put out plenty of light on the patio
|
Solar batteries also power the six 3 Volt LED landscape
floods dusk to dawn.
|
New panel on wall in background replaces the two home
depot solar panels with
integrated battery packs.
After 3 yrs, these panels had begun to lose their effectiveness.
