More about off-grid solar systems:

Off-grid power systems supply electricity to properties that are not connected to the public electricity network.   These systems are independent power stations capable of powering a wide range of applications with dependable and reliable electricity that is no different from that supplied by the national electricity grid.  Whether it be for a small or large new or existing home, a station, business, or an entire community that depends on large diesel generators, off-grid stand-alone power systems are commonly the reliable, clean, hassle-free, cost-competitive answer.

It is Specialized Solar Systems recommendation that energy saving principles are put into practice and taken into consideration before such a system is purchased, for example, low wattage lighting, gas stove/geyser, etc.

Please note: This solar system PV solar panels are calculated using the solar irradiance factor for George, the Western Cape South Africa. When requesting a quote or if you require expert help with choosing the correct Off-grid Solar System from Specialized Solar Systems, customers must please include the location where you plan to install the off-grid Solar Energy System.
