OFF-GRID POWER SYSTEMS
When the utility power is unavailable or too
expensive to bring in to your home or cabin, solar panels allow you to be your
own utility company! You can live in peace, with no noisy gas generator
to disturb the quiet. There are several variations of off-grid solar
power, depending on your needs and budget.
Off-grid DC Solar Power Systems
Larger ViewDC off-grid solar power systems are most often used to power DC appliances in RV’s, boats, and cabins, as well as farm/ranch appliances like cattle gates and rural telecommunications systems when utility power is not accessible.
DC solar power is less expensive than AC solar
power because an inverter is not required to convert the electricity produced
by solar panels and stored in batteries from DC to AC. But DC solar
power does NOT power standard AC appliances.
Off-grid AC Solar Power Systems
Off-grid solar power also stores DC electricity
in batteries. The addition of aninverter allows this system to convert DC electrical current coming from
the batteries into AC or alternating current. AC is the standard form of
electricity for anything that "plugs in" to utility power and is the
appropriate current for common household appliances.
While AC off-grid solar power systems are more
expensive because of the cost of the inverter, the appliances you are able to
use are less expensive and there are more kinds of appliances to choose from.
Off-grid Wind Systems
As with solar off-grid systems, the off-grid wind system
stores electricity produced by the wind generator in a bank of batteries.
An inverter can convert the DC electricity to AC to run common household
Off-grid Solar Power for Remote Telecommunications
Small off-grid DC solar power systems can power
tele- communications electronics in locations which are far away from power
