Your Questions About Solar Generators For The Home
Robert asks…
Build a solar or wind propelled generator?
I want to know how to make a solar or wind propelled generator? First if i can make a solar and wind propelled generator and combine them to work at the same time. The solar panel can be around 12 volts. I just want to do this as a home project. I don’t want extreme power out of this. I am young but have a lot of experience with building electronics so keep it simple enough for me to do it.

Well i dont know much but i hope this will help, i whould imagine for the wind power you whould need the light propeler to be somehow conected to a magnetic generater. And for the solar power, well i dont know much about that but i hope to find out soon.

How many solar panels does it take to run an A/C unit? Also, How many batteries in an array?
I was wondering how many 700 W solar panels it would take to run a household A/C unit. Also curious how many batteries it would take to keep A/C running in inhospitable environments. Would a 3500 W inverter be enough if it were to run 220 AC?

Here we are doing the math of two facts to multiply or divide, to find the third, and you don’t give enough to make up the equation!
My 2.5 ton unit needs 220 VAC at 5 KW for the heater coils, and 3.5 KW for the cooling and fans, but, in electricity, we are always having to discriminate between inductive loads (transformers, oven coils, heater coils) and other uses, like lncandescent lighting.
To run my HVAC unit, in my 1,000 square foot home, would demand a10KW unit, and the 5200 watt (5500 watt Surge rated)
would not work. A generator simply stalls out under load, possibly smokes the generator electrics, while a solar unit and batteries can reverse potential under severe load, and explode!
The surge rating for my HVAC unit is 3X higher, (the Switching Load), for either heating or cooling. When figuring out the generator load for an emergency generator, for warranty purposes, they demand we install a generator with a ‘surge’ power rating triple the start-up load of our equipment, and that is the way to try to load your Solar panel, also!
Now, go to the hardware store, and get a booklet or pamphlet about emergency power generation, and look at the descriptions of the generator start up power capabilities for the ‘switching loads’!
