So after reading about Another Stupid Internet Challenge I'm wanting to start one that ISN'T dangerous and might give us all a good chuckle. Many of us are dealing with winter weather on our systems and finding that the math and reality aren't even close to each other. So here's the challenge: How badly does your little starter system run? Here's the rules:
1: Go to the JRC Photovoltaic geography site.
2: Plug in your little array's information, you can use the old info if you've changed it around in the last 60 days.
3: Grab a screen shot of the bar graph off the bottom showing how much dead battery time you have and what your output SHOULD be.
4: Post a quick breakdown of wattage, battery capacity, and load.
5: Laugh (or cry) at your numbers along with the rest of us sharing in each others misery.
Winner becomes eligible for a spanking with a wet noodle, or something equally as ridiculous.
I'll start:
Driveway lights: 100w panel on PWM, 30Ah of AGM batteries, 120Wh/day load. 8 months where I'll have "Dead battery days"
