Building your own Solar Panel in your Garage

jeroen8 writes: "A Dutch guy was able to build his own solar panel in his garage which is 3 times less expensive than mass produced solar panels currently available on European market. He bought his solar cells on eBay and created his own solar panel. His cost price is only 1.20 euro per Watt Peak (Wp). This makes you wonder if we are not paying too much for mass produced solar panels, which should in theory be a lot less expensive than something you create in your garage. What do you think? Are we paying to much?"
