Can I run my house off solar or wind or generator directly???
Here is a misconception.. your being told that you can run your fridge off solar panels… lets do the math…
Solar panels depending on the size will generate X amount of electrical energy…
Lets pick a 250 watt solar panel… at a cost of about 300 US dollars each… this does not include the regulator to keep the voltage as a save level to put a charge into your storage batteries… hmmm.. there is three items so far you need, the battery(s), regulator and photo voltaic cell… so a cost so far about 500 US…
How much power is that? Well it says 250 watt.. but we are use to understanding a 100 watt light bulb.. so am I saying you can run 2 and half light bulbs??? Not on your life…
The 250watts of power is based on 12 volts so at 12 volts, the working energy  relates to 20 amps… sounds like a lot if your looking at your power panel in your house, but we are only talking 12 volts…
How much of that can I use in my house?... well we now need an inverter that converts 12 volts to 120 volts.. which is 10 times… so the 20 amp devided by 10 is only 2 amps of power.. plus the cost of the inverter…. To be able to run your fridge, of about 8 amps, that is about 960 watts on 120 volts or if your running it off your solar panels and batteries.. your trying to draw 80 amps from your batteries which will now only run for about a half hr before its drained.. and to keep that running on a continuous basis, we are now talking 1000 watt solar panel to run at full capacity to maintain your fridge but only during the daylight hours… plus the fact that the inverter will not be running at a consistant voltage or proper wave form as a regular high wattage inverter only outputs a modified sin wave, which means that your fridge compressor will burn out in no time…, this goes for any electrical items other than some lighting…
How to overcome this dilemma? Run items at 12 volts… which means to modify items in your home to run at 12 volts… can you run a toaster at 12 volts? Well yes, they do have them available from some shops.. but at a draw of 80 amps to toast your bread…
The best way to use solar panels is to have a number of them so that they generate about 120 volts back onto the grid ( this has to be done by a specialty electrician or company and approved by your local utility), that way, you put power onto the grid and get paid, but you will for sure use up more than your put in.. but it is a savings just the same..)..
Wind works the same way and regular mechanical generators will work ok but only if it’s a very good quality to get the power at a steady voltage and not fluxuate… and that the sin wave is consistent or your appliance will fry from running to slow or to fast. Know your power supply before you use it…
I use my solar panel(s) for keeping two batteries charge ( deep cycle). But I use one panel to feed a fan in the attic to keep it cool, thus saving on my air conditioner bill, ( I use a 12 volt cooling fan for a radiator and only runs during the daylight hours if the sun is on the house). The other panel is used to keep my batteries charged and use one for my LG TV which runs off a low voltage transformer, I found this out by accident, so it runs great for free… and I also use the solar to run my security cameras and capture for free.. I did however install a small marine panel with DC breakers to protect my items… and oh yes, my under counter lighting is also off my solar package and also installed emergency lights that double as very bright hallway lighting by installing led strips in 4 fixtures that I got at a garage sale. And my solar powered pathway lights and lighted address run all night and have then turn off by a solar switch…. You just have to use a bit of common sense when thinking green… I am not done yet either.. my inverter can run my toaster, but I would not trust it for my other tv … you can however, install a mini hot water tank and change the heater and use the energy to warm the water which allows the hot water tank to run less . but it involves some investment…
Think out of the box…
