Current summary of our renewable energy production:

Production efficiency graph:

The graph below shows today's production from our renewable energy systems.  To normalize for the different sizes of our various systems, output is stated as "production efficiency" which is defined as actual output divided by manufactors stated maximum output.  Thus, a performance efficiency of 100% (or slightly above) represents a rare situation with ideal sun or wind conditions that are as good as or better than those expected by the equipment manufacturer.  By stating our performance as production efficiency our data is more useful to people considering building their own renewable energy system, as this gives a realistic estimate of what can be expected in our climate conditions.

The three lines of the graph represent our three renewable energy systems.  Red corresponds to our 10,800 watt fixed solar array on our social hall roof.  Green corresponds to our 2,550 watt two axis tracking solar unit.  Blue corresponds to our 2,500 watt wind turbine.

Multi-day production efficiency:

This graph shows the same information for a longer time period.

Absolute power output graph:

The next graph shows actual power output (red=fixed solar, green=tracking solar, blue=wind, black=total)

Monthly production graph:

This graph shows the monthly average power output for each of our systems (red = fixed solar, went online December 1, 2010, green = tracking solar, went online December 10, 2011, blue = wind, went online November 30, 2010, black = total)

Local wind speed data:

Data is collected from an anemometer located on our monopole slightly below the main wind turbine.  Wind data is inherently very noisy; this plot is a running average of the most recent 15 minutes of data (sampled at 10 second intervals).

Astronomical data:

Comparison of current and historical data:

The thin lines are these graphs represent the percentile ranges for our output at each time of day.  The thick line is the data so far for the current day.  If the current day lines up with the 50th percentile line, we are having an average day; above or below this represents better or worse than average.
