Using Solar Energy to “View” the EclipsePosted by karen in Front, on August 22, 2017
One of the more unique methods of “viewing” the eclipse is to watch the real-time monitoring from a solar energy systems along the eclipse path. Below is a graph from one of the dozens of systems we have installed in BC. Notice the smooth downward curve as the moon blocks the sun.
The system shown above produced a 130 kWh on August 21st. The day before it had produced 133 kWh. So that was only a 2% drop in production. Energy systems along the path of totality would have seen a little larger drop.
A cloudy day compared to one with full sun can result in production drops of more than 50%. So the eclipse effect was much smaller than the natural variability that occurs regularly. A grid of 100% renewable energy can be designed to handle this variability using a combination of firm base loads (like hydro-power and geo-thermal power) and storage (batteries).
