During the heavy snowstorm of late February, a disruption to our array occurred. The direct current generation was "off" and caused the inverter to trip a fuse (as it would normally do to protect it's electronics). The system as a whole has worked well with little down time since it's installation nearly a year ago. There were 8 days in 2009 where the system as whole was non-functional. Circuit boards in the inverter, or power outages from the grid caused such lack of output. Note that I don't say mis-function, as when their is a power outage, our PV Solar System will not push energy into the grid.
In 2009 electric year (2008Dec18 thru 2009Dec16):
- Our system was in place for 269 days (8 of which there was no production).
- The average system output over those days was 343kwh/day.
- The average consumption of our operations in that same period was 301kwh/day.
- Highest daily electricity generation was May19 with 695kwh.
November and December were the only months that the PV Solar System didn't generate more than our entire operations electricity consumption. Overall since operational, there has been more electricity generated from the sun than is needed to power all our lights, computers, and equipment in the entire office and manufacturing plant. Since 114% of consumption was generated from a "renewable energy" source, state regulations require that the excess kwh be carried forward as a "credit" on the utility account, to be drawn down upon in a future billing period.
