12V Cheap Solar Panels
12v Cheap Solar Panels can now be utilized in small scale
solar applications to power 12v devices. These applications
would include mobile solar systems such as caravans and motor
homes, or small solar installations like powering a small shed
or garage.
The purpose of the panel will know what size panel you need.
Smaller panels such as 5, 10, or 25 watts are ideal for
charging phones, digital cameras, iPods and laptops and now
come in conveniently sized modules for portability and
efficiency.
Larger sized panels such as 40, 80 and 130 watts are ideal
for powering outdoor lighting or garden features, appliances
like fridges or microwaves or combined in a solar array to
power homes in remote areas. 12v solar panels are a convenient,
eco-friendly way of generating electricity and after they are
installed, there isn't any on-going cost or maintenance.
To produce a 12 volt system you will also need a solar
regulator and batteries to store the solar energy. By storing
the energy in the battery, you're guaranteed to always have
power regardless of what the temperature is like. To estimate
what sized panels you'd need, you need to consider the wattage
from the device and how long you desire to power it for.
For instance: To light a 20 watt globe for 10 hours will
need 200 watts (the wattage rating of any appliance indicates
just how much power it uses in one hour). Assuming 5 hours of
peak sunlight daily, means you'll need a cell capable of
producing 200 watts in 5 hours, i.e. a 40 watt panel.
