Weather report: 2/17/11 |
Big storms of all sorts wreak havoc in our rural mountains just as they do in towns. The roads can be closed, flooded, or dangerously icy. The wind will blow away what's not secured. And wind, snow, trees, auto accidents, wildfires and other incidents can interrupt electric power. That's the case in this storm. I found out via a phone call from someone, otherwise we would have never known.
This is when the power independence of our self-sufficient lifestyle really stands out.

Hydro-system, Pelton wheel inside barrel |
The rain and runoff that started before it got so cold got our hydro running, and the snow is now building up a reserve on the mountain above us that will last long after the storm is over. Generally our main winter season power source, running steadily 24 hours a day, hydro-power is almost decadent in its abundance.

The wind turbine from up the hill |
Located on a point above a river canyon, it gets wind morning and evening most of the year, but it really kicks into gear in stormy weather.

Looking up at our wind turbine |
But the real workhorses of our system, despite being the only ones with no moving parts, are our solar Photo Voltaic (PV) panels.
Patched together over the years (there are 3 slightly different styles in our array), if there is any light, they are producing some power. And, since there is far more sun here than other weather overall, I think I can safely say most of our annual electricity comes from these panels.
On top of that we have 2 smaller PV panels that pump water from our spring up to a holding tank, another small panel that runs the pump on our solar hot water system as well as an attic fan, and a tiny panel that runs a fan in our garden's greenhouse.

Our solar PV electric array |
In fact, it is solar energy that runs all these systems, as it is the sun's influence on our planet that creates the weather and controls the water cycle that makes the other methods work.
Even on a dark blizzard of a day like this one.
I think I will go have a hot cup of tea and warm up!
9/2014 Update: This spring we added 5 new Solar PV panels to our system, bringing us to a full 4 kilowatts of charging power. We bought them a year ago when we had the money and the price was good. That almost never happens at the same time! And we finally had the opportunity to build a rack for them and add them to our array this year. It's wonderful to have the extra power.
