Good Morning Occidental!
Today (Sunday, March 4, 2018), Occidental's 1 MW solar array is 5 years old.
In the last year the array produced 1.87 GWh of electrical energy. For comparison here are the numbers from previous years,
1st year = 1.82 GWh
2nd year = 1.88 GWh
3rd year = 1.79 GWh
4th year = 1.82 GWh
5th year = 1.87 GWh
The yearly output of our array has varied less than 2% and shows no signs of slowing down. The lack of variation seems odd to me because of huge, yearly variations caused by cloud cover (negative effect, -), rain (positive effect, +), dust (-), cleaning (+), weeds (-), weeding (+), inverter failures (-) and the odd solar eclipse (-),
If you want to monitor the array yourself you can log into our solar array monitoring website,

Apps for your phone can be found by searching for the company which runs the website, AlsoEnergy.
On the financial side of things, our electrical bills have been lower these last three years due to the energy generated by the solar array. Over the last year the solar array saved the college $278k. For comparison here are the numbers from previous years,
1st year = $250k
2nd year = $293k
3rd year = $233k
4th year = $248k
5th year = $278k
