Powering Just One Appliance with Wind and Solar Energy
What is the #1 Reason why homeowners don't
add Wind or Solar power to their home?
$$ COST $$
Wind and Solar generating systems can be very
expensive!
For this reason, thousands of homeowners are learning how
make their own solar panels and windmills (wind turbines). It is amazingly
easy and doesn't require much technical knowledge. We've
reviewed the best guides available on the internet and rated
them.

If you want to start small, yet save as much money as you can,
you can power just one appliance at a time with solar energy.
So which appliances are best suited for being powered by solar
or wind energy?
It depends on the size of your system and the ampere or
wattage rating of your appliances.
You can look on the nameplate of many appliances and they will
either tell you the amp rating or the wattage of the appliance. The goal is to
find the wattage, but you can determine the wattage by finding the amp rating.
Wattage is Volts multiplied by Amps.
If your appliance doesn't have an amp or wattage rating on the
nameplate, you can purchase an
ammeter to measure the amp draw of the appliance.
To test it, you will have to find a way
to place the clamp of the ammeter around one wire that feeds the appliance
alone, or remove the cover of the circuit box and place the clamp of the
ammeter around the one wire that feeds the electricity to the appliance.
To determine the wattage, multiply the voltage times the amp
draw of the appliance. For instance, 120 volts X 3 amps would be 360 watts.
Sometimes the appliance will give you the wattage on the nameplate. This can
save time and effort. So what appliances are well suited for
Solar and Wind Energy systems? You want an appliance that gets used a
lot, and yet doesn't use too large of a quantity of electricity so that
you can start with a small system. One of the best appliances you can
start with is the Refrigerator or Freezer. Here are some reasons why: 1)
They use between 300 and 800 watts so an inexpensive inverter can be
used. 2) Refrigerators run quite often and use about the
same amount of electricity every month 3) They are
something that is typically always in use, even when you are on
vacation. 4) Because of the constant usage, you will
notice a drop in your electric bill even though you have a small,
inexpensive system. 5) If you build your own
solar/wind energy system, it will pay for itself within months and save
you money for many years to come. Here are some other
appliances and the typical wattage ratings of each:
