41. At 0.2% loss per year...

Panels would still be producing 82% of their initial power after 100 years.

It's time someone released "whole roof" systems in which you rack the trusses and bolt on a 100+ year roof of solar panels.

Design the trusses to give easy passageway underneath the panels for wiring access. That would also get the connectors and micro inverters out of the weather and lower future maintenance costs.

Just think about the power produced if new housing was designed to optimize panel orientation. With the rapidly dropping price of panels it would probably make sense to cover east and west facing roofs in order to extend the solar day.
