Solar Panels - Quick Info

Well, we had someone stop by the house today about Solar Panels.  Not many companies will sell you a mono crystalline solar panel - most simply advertise and sell only the cheaper polycrystalline panels.  These guys were more than willing to sell whatever panel you want, including the Panasonic VBN325SA16 325 Watt panels.  They suggest about 16 panels, and gave an estimated 23k cost (panels, a SolarEdge power inverter, and installation costs).  I know I could find 16 of those panels on eBay for $7,000, but the installation costs and the warranty just might be worth it.  It's the first real time I've thought about a company actually doing a Solar install rather than me.
