Using Solar Energy to “View” the EclipsePosted by karen in Front, Our News, 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).
