High energy cost and use might make sense over long period of time (20yrs)


What You Need to Know


A solar system has to pay for itself in 5yrs or less to get approx 20yr return on your investment. The current system costs WITH government subsidies equate to > 12 years and without >16 years.

Maintenance Requirements:

The cells and electronics might be warranted for 25 years however almost ZERO of the suppliers or installers have 5 year histories let alone decades. Good luck getting any 'warranty service' from any of them beyond a few years.


Pencil out the costs and benefits and compare them to other investments.
