Extending Life of Solar Panels by doing Real-time diagnostics of Health Data:

Purdue researchers created an algorithm using the physics of panel degradation that can analyze solar farm data from anywhere, essentially as a portable EKG for solar farms. [...] Real-time diagnostics would ultimately inform better panel designs – the cost-saving "treatment" that could prolong lifespan and continue to cut electrical bills.

[...] The algorithm is in an experimental stage, but already downloadable for other researchers to use through a National Science Foundation-funded platform called Digital Environment for Enabling Data-driven Science (DEEDS) at https://datacenterhub.org/resources/14754.

[...] In the long term, the researchers hope the algorithm could show how much energy a solar farm produces in 30 years by looking at the relationship between weather forecast data and projection of electric circuit parameters. Integrating the algorithm with other physics-based models could eventually predict the lifetime of a solar farm.

    A related online solar calculator is pvwatts found at https://pvwatts.nrel.gov/ [nrel.gov]

    It uses real hourly insolation and weather data collected at hundreds of locations over fifty years.

    I used it when designing my solar system and found it to be very accurate.
