Many rural regions are too sparsely populated to justify building a central energy supply system. This is where off grid solar systems excel. They can supply buildings and factories with reliable off-grid AC power using solar energy. In contrast to on grid home systems, off-grid solar power systems can power any household appliances, electrical tools or machines that run standard AC power irrespective of the presence of power grid solar o_ grid systems can be used in any location that lacks a stable supply. In many remote parts of the world diesel generators are used to generate electricity for mining operations, remote communities, telecom towers and other installations and facilities. Apart from the negative effects on the environment diesel also puts a heavy strain on expenses and financial planning.
