It is interesting to learn about the experience people had buying solar panels together. Logically they should be offered lower prices; however I am not confident that every company will offer such opportunity. When we installed the PV panels on our house, our neighbors didn’t believe that this alternative source of energy works. So we just made an order on the website http://solarpanelscompany.com/. Now there is no use to explain the benefits, though the prices differ a lot.
