Solar Water Heater - Design
I would also recommend that you order the book for yourself as it has a wealth of
information in it which you should have, don't just go by what I say :)
Here are my plans for the pump controller, they are low-res images, but if you
would like the PCB design that you can print and build yourself,
contact me and let me know and I'll email them to you.

The Solar Controller
The PCB shown here is the version I modified after my initial
prototype. It works really well, and with a relay that can switch upto a 6A
load (i.e. the water pump) it should service our needs perfectly.

Hopefully they make sence!
