It’s Not Murder If You Kill-a-Watt

One of our dark haired, witty, and charmingly brilliant residents here at the FLAT has been crunching the numbers on our home’s solar output. Though suspected of being member to an underground bagpipe band, our FLATmate has come through to make sense of tricky spreadsheets and kilo-loads of data.

Since the James E. Todd building on the University of Montana campus uploads daily power generation averages (the FLAT used to do this before the wireless router was moved to the studio), we used Todd building daily data and applied it to our own array to get an estimate of what our daily average is.

Spring 2011 to March 21st, 2014 average daily estimation of the FLAT solar array using Todd building solar array data for base estimates.

As of March 21, 2014, we had generated 8729 kWh (kilowatt-hours) of electricity.Using assumptions of Northwestern Energy’s power production mix (how much of NWE power is from coal, gas, hydro, etc.), we then figured that, to date, we had saved about 5.4 metric tons of carbon dioxide equivalent (CO2-e) by using solar power rather than purchasing power.  Just trying to brighten your day with our solar array!
