Solar powered pump for open loop system.
Hi All, does anyone know where I can purchase a small dc motor that will pump water from my tank to a flat plate collector? I need the pump to run from a solar cell with a max output of 5 watts ? I have seen a system made by solartwin & think I can make it on the cheap Smiley but need a bit of help on the motor side. Any help would be great thanks.

try searching for el-sid. It's a dc powered pump that runs on low wattage. Only compensation is low head.

Hi alan how did you get on with you home made solar panel powered pump. I am interested because I run a
solar water heating, www.aztec-solar-water-heating.com, company in the UK and was wondering about adopting a solar panel driven pump as an alternative to mains powered pumps but found the options expensive aswell

Mark,

The Laing D5 pumps are very popular these days for powering solar water heating via PV.  They are under $200US.  You can see them at http://store.altestore.com/Solar-Water-Pumps/Circulating-Pumps/Laing-D5720B-PV-Circulating-Pump-sweated/p6065/.
