Step 9: Conclusions
If you find this instructable interesting please comment. If you have suggestions please comment. What other types of heat exchangers could be used? I still have enough PV cells to make a second panel, but I would like a cheaper and simpler way to harness the thermal energy. Any suggestions are welcome.
Please enjoy and if you decide to make a panel like this let me know. THANK YOU.
Note (added May/13/2010): a google search reveals that there is apparently some commercial systems that use the same concepts (using both the electricity and the heat in a single package). Please see, for example: http://solarwall.com/en/products/solarwall-pvt.php, where they use air convection on the backside of the panels (instead of water).
