What is the best solar panels to power your house?

I need to power a refrigerator, and a few small items. I do not foresee not operate an AC unit.

Any commercial grade solar panels will do. The big question is how much you need, and if you need storage. If you plan to go out of the toaster, you will need to design a system large enough to provide for both normal use and storage enough to lead you to periods without sunshine – and night, of course. The rule of thumb is about 3 x your peak load, with enough storage for a full 24 hours of no sun. Suppose that your refrigerator uses an average of 800 watts per hour and works 8 hours a day (probably a bit high in both cases, but better to be safe). Suppose your total average additional charge is 800 watts – Hair dryer _NO_ sense, flat-screen TVs, vacuum trucks, electric heating, washing machine, dishwasher, electric stove, and so on. You will need a system with 5000 watts 30 000 "watts" storage. It is a bank very large number of batteries you could imagine. Your approximate installed cost will be something on the order of $ 40 000 – 60 000 USD, or $ 8 – $ 12/watt according to many factors.

How To Build Wind Turbine Blades

how to build wind turbine blades
What makes the 3 thin blades on wind generators more efficient then say, a decorative country windmill?

If you look online for wind generators you’ll find a truck load of pictures of windmills that are mounted on thin poles that only have 3 thin blades. I’ve taken it up as a hobby to find how & to build myself one. But I’m retro. I don’t get why those 3 thin blades hooked up to a rotary engine sort of machine could be more efficient then then the nice homely country windmills that are composed of 6-10 blades inside a metal ring with of course the wind vein mounted on the back. I can understand this with those gigantic wind turbines on wind farms but i just want a smaller one based off one i could buy at a farmers market or something like that. I don’t want to stick it on a 30′ pole but instead plant it right on the roof of my home & run it like that.

Okay random wind physics genius who just happens to see my dilemma, tell me what I’m not putting together here please.

It’s actually not (just) efficiency that causes most wind turbines to only have 3 blades instead of 6 or 10 or such. Increasing the number of blades does increase the aerodynamic efficiency, but the increase gets smaller each time. For instance, increasing blade number from 1 to 2 ups efficiency by 6%, while 2 to 3 ups it by only 3%. The fact that more blades also mean smaller blades – so they can all fit – mean that eventually the efficiency benefit gets so small that the lack of stiffness and amount of materials becomes simply too much. Also, the fewer blades allow higher angular momentum (rotation speed) and decreased cost.
