however non tracking panels reduce power by 50%, and non-south lattitude 
orentation reduce output to less than 25% of what is possable.

the photo shows panels being installed flat with the roof line, which is 
very inefficient.

Also the cost of just installing the pannels exceeds the cost of the 
pannels making payback time over 10 years.

Additionally, Solar panels will have to be replaced every 30 years. (US 
Gov says that)

Making solar panels requires very toxic materials, and huge amounts of 
water.

The amount of cost put into the panel will never be recovered by the 
electricity it generates.

Pannels are more efficient when put into large fields and track sun, 
where installation costs are minimized.
