How many AH do you use? Is ecoworthy worthy?

[torismaul1981]

Question to those on solar already. How many amp hours do you use on an average day? I found this nifty calculator Size Your Go Power! Solar or Inverter System | Go Power! thanks to another post I was searching and found I'm a conservative 60ah/day.

On another note, has anyone used the ecoworthy line of solar panels? While price shopping, I found a kit that has a 1.5k inverter included with 4 100w solar panels and solar controller with mount and hookups for $765. Is this a reputable brand? I've found reviews online that say both, and I value the opinions of this forum so much more, so please, give me the low down.

I know polycrystalline isn't the most efficient, instead go with monocrystalline. You can always tell a mono if there's white squares in between each box on the panel. I looks like a good deal but I wouldn't since it's not mono. I'm in the solar stage right now too!

My usage:
3600 watts per day
I'll need 400 watts worth of battery power
I'll prob get 6 100w solar panels

I could be wrong but my understanding is that a 100 watt panel is a 100 watt panel, regardless of mono or poly. The increased efficiency of mono usually just means smaller dimensional size of panel, but same output.

Its also important note although monocrystalline is more efficient in prime conditions they are not as good with a little bit of shade. A couple slivers of shade can in some cases shut down monocrystalline panels. Obviously no solar panel is good in shade but polycrystalline is a little more tolerant to it than mono. I will be spending a lot of time in the northwoods of Minnesota, Wisconsin, and the UP so opted for the poly. My 2 cents.
