What's off grid solar system?

Issuing time:2012-06-04 13:20

One of the main types of the solar power system is Off-grid — also known as a stand-alone power system. It works by generating electricity from solar panels and using it to charge a solar battery via a charger controller. That electricity is then converted using an inverter so that it can power the home or business appliances. By saving the electricity in a solar battery, it is possible to run home with solar energy, even at night or during times when there is   less   sun exposure.

Components of an Off Grid Solar Power System

Solar Panels

The precise size and production capabilities of individual solar panel array which is the first ingredient will depend on the amount of available sunlight in the region, the usable space of roof, and energy consumption needs.

Solar Batteries

A solar battery is needed to allow home to continue to run after the sun goes down. Solar storage device will charge throughout the day as solar panels generate excess electricity. Rather than simply losing out on all of that available solar power, a battery enables to keep it for later use. Depending on energy needs, a single battery, or even a battery bank is used.

Solar Inverters

In order to convert the direct current (DC) collected by solar panel array into the alternating current (AC) for running most of common household appliances and electronics, solar power system needs a solar inverter — sometimes referred to as a solar converter or a PV inverter. For an off-grid system use a stand-alone inverter.

Solar Charge Controller

The solar charge controller or battery charger is essential to save battery. The controller regulates the voltage and current that solar battery receives, to prevent overcharging and damage.

Alternative energy source

It may be worth considering an alternative source of energy as back up of the system. This is needed during the depths of winter when solar production is at its lowest. Many owners who use off-grid systems combine them with a generator that can power home’s electricity needs.
