30 Watt Solar Panel Give Away (SHOW US YOUR SMALL PROJECT)

[Dakota2004]

City Park Solar Light Project

Here is my first solar project. I think it came out well. Works great.

The light in the city park bathroom is a light-emitting diode (LED). It runs off of 12 volts and draws 4 watts of power. The LED light is activated by a motion sensor switch and is only on when someone is in the bathroom. The batteries are charged by a solar panel and solar charge controller. The batteries, charge controller and wiring are housed in a 12x12x6 PVC box in the bathroom. The solar cell is position on top of the bathroom.

Here is a breakdown of the parts and cost:
Everbright 35 watt Polycrystalline 12v Solar Panel 2.23 amps
Morningstar SunKeeper 6 Solar Charge Controller
LED 12 volt lamp ceiling fixture
PIR Motion Sensor Switch DC 12 volt
PVC 12x12x6 enclosure, conduit and associated parts
Wire, crimp connectors, miscellaneous hardware
2 each 12 volt batteries, YUASA NP7.5-12 (7.5AH)
Total Cost of this project: 141.99. The miscellaneous hardware and batteries I had so I didn't add the cost of them.

Guys, lets hold off the new folk bashing, till they have proven themselves worthy. A couple blunders in 1 or 2 posts, and you have the jugular sliced already.

what will 30 watt panels power on a regular basis?? im totally new to this and just trying to grasp a basic concept. i used to be an electrician n know that 120 watts is an amp so im guessing that 30 w is basically a 1/4 amp like a cell phone charger could be powered maybe? is that right or am i over thinking it completely??

Are you sure you were an electrician?

120 watts = 1200 volts x 0.1 amps
120 watts = 120 volts x 1 amp
120 watts = 12 volts x 10 amps
120 watts = 1.2 volts x 100 amps

All four equations are True equations.

I am working on my first project, but the only photo of the progress is me looking confused reading this forum. Given I am in my Scoobie-Doo undies and haven't been tanning, I will forfeit my chances at a win rather then post the photo. Good luck top the rest of you

BSHARP76 its good to know you gave up doing electrical work.. i used to be an electrician n know that 120 watts is an amp That would only be true if its also 120v. You may find its not quite correct if you have 12v and 120w.
