create a 'solar' light... very cool idea that's possible with most anything - by Shabby Creek Cottage
By using standard 2Watt Polycrystalline cells, available on sites like eBay, you'll enable yourself to build a 100 Watt panel for around $125. Some people even opt for chipped, or B-Grade cells, that produce the same amount of power but are defective by the manufacturer's standards (ie chipped corners, etc). With this choice of solar cells a completed 100 Watt panel may cost less than $70.
