REVTOS Monitoring System Panel

As of Aug. 20, 2012 the energy usage in the house went from a high of about 1400 KHW used from the grid back in March (when there were still many power tools, halogen lights, etc. being used in construction) to -1275 KWH (more pushed back onto the grid than consumed in the house for the first 8 months).

Solar PV Irradiance Versus DC Output

A nice clear day with very good irradiance levels all day. Comparing the DC output of the solar system (the yellow line), it can be seen there was snow or a heavy frost on the solar panels that prevented full power output until it melted off at about 10 a.m.

Solar Thermal System Monitoring

On a day when the outside ambient temperature is 35 degrees, the water in the solar thermal tank is already 110 degrees!

PV System Info on Jan. 30, 2012

Good irradiance level, but the solar PV power output is very low. A look through the webcam shows snow cover still on the solar panels (see below).

PV System Info on Jan. 30, 2012

Snow cover is preventing power production from the solar PV system until the snow slides off the panels.
