Your 1.4W LEDs
Your radio alarm, your radio
Your battery (AAA&AA) charger, your mp3 player, your cell phone
Your small fridge (the 6 beers model
Your Internet router, your wireless router
Your laptop, but only a few hours a day
Your TV decoder and TV set, sorry.
But like with simple solar systems, simple wind systems will not deliver a lot and will never pay for themselves, except if you DIY some parts and get second hands for other parts.
See my calculation for a
single 24/7 20W laptop on a "simple" solar system.
I heard that where there is the most wind, a wind system generates a third of its maximum. Where I live it's a tenth
so only for the wind mill it will pay for itself in 20 years. Add the charge controller, the batteries and the inverter...
What is the most expensive is the batteries. I would like to have a system that connects directly to the internal electric network to feed a part of the little 24/7 electric systems.
Denis.
