Website link PV panel degradation [RE-wrenches]

[Todd Cory, Mt. Shasta Energy Services]

Unfortunately the test results are after the first year only. I am curious if
that level of degradation continues. I have heard thin film modules lose most
after the first month or so and then the rate of degradation decreases
substantially. I would like to see actual test data on this.
