Wind power in NWPA

After a couple days of research……

Wind in our area is AVG 8-10 MPH.

Most homemade wind turbines only work in 13mph or higher.  So homemade power is out.  However…

Talks about the new Honeywell wind turbines that can produce electric in as little as 2mph.  They also can mount to a roof easily.

So this makes me think, that you could possibly to a solar/wind mix for power, keeping the genny as a backup.

Although the cost of this is high.  I am leaning towards the idea of a power trailer.

This would allow us to position the system where the best sun and wind would be.  This allows it to also be used in an offsite building location if needed, and keeps the house from having to be damaged installing equipment.

 

Just some thoughts.

Design Decisions

I read an article recently about off grid vs. on grid power, and how to choose and scale systems.

Basically there are three choices:
1. off grid (produce all of your own power, no connection to the public utility grid)
2. on grid (power comes from public utilities)
3. on grid with backup (a natural gas or propane fired generator provides backup for critical functions – heating, refrigeration, pumping water)
4. off grid with backup (produce most of your own power but use the public utilities as backup or supplemental source)

There are pros and cons to each model, and, as with all things it seems, cost is a primary driving factor.

I think at a minimum we should have a backup power source for heat and refrigeration and water.

Solar lighting

We bought some solar flood lights for loading the wood stove at night. They worked ok till it got cold. Then the lead acid batteries would freeze up and no light. Also, snow would lay on the solar panels making it not charge.

I think solar is the answer, but the batteries will need to be inside so they don’t freeze up and a system for keeping snow off the solar panels will have to be instituted.

Incidently our solar path lights use a nickel cadmium battery and they seem to work no matter how cold. Although NC batteries develop a memory over time and won’t stay lighted as long as they once did.
