Hi bullwinkle,

If you have not already, check out the Home Power web site:

http://homepower.com/home/

their archives are chocked full of info for small systems like you are talking about.....

Hope this helps.........

ok so stick with the big battery.

good

progress

Yup, I think $ for Watt it gets better as you get bigger, up to a point anyway.
It certainly does in Thailand (baht/Watt)
Electricity is so cheap here, almost no one bothers with solar, shame 'cos you get cloudless sunny days for 9-10 months of the year.

No grid connect incentives, the only panels you see are in the tiny villages in the jungle and ironically in the mega-bucks hotel chains.

Argghh! Now I have to read another entire site

Thanks, I don't think I've been there yet.

and by way of reply, if you dont know fieldlines it's well worth a look. A very BYAP style community worth a visit.

I guess you don't have such a meddling over taxing government like ours
"Save the world, give all your hard earned money to your great rulers!"

to keep keep it simple just mulitply your 24 hr power consumption by 3 and that is nice conservative value for the solar panel to provide. I think

to cover everything? ie saving some for a rainy day, inverter losses, battery self discharge etc etc etc

Are you saying for a 20 watt pump I should have 60 watt panel?

Tell me I dont have to think any more and I can just do that

Don't think any more, just do that.
Or maybe an 80 Watt one, to be safe

Or a 150w one and come up with some other crazy uses for the excess

I wonder if the government would give me a rebate on a single solar panel if I said I was homeless and needed only one

I wish some of the homes with solar on their roof would start being demolished so we start seeing a glut of second had panels

money is the only thing standing between me and everything else

yes, yes, here here !

The http://www.energymatters.com.au/ website has a standalone calculator that might help.

I picked up a 15w panel off ebay for $40. Does produce its rated claims will see how long it lasts. For what I wanted even if the output drops a little I don't care.

Edit:
I just brought 2 215w of these recently for $390. But its a 28v panel.
