"To make the best-suited choice you first need to determine what type of solar power system will meet your needs the best. There are 3 types of solar power systems and understanding the basics about them will help make an informed decision."
The types are:
An On-Grid System is very commonly used. This system is linked to the main electrical grid. Thus, the user can use both –solar energy during the day and the grid’s electricity during the night. The most advantageous feature of this system is that the surplus energy produced during the day can be transmitted back to the grid. And your electricity provider will pay you a feed-in-tariff. Thus, it can be used somewhere else or can be used by you on a cloudy or a stormy day or at night time in case your solar panels are not able to produce enough for you.
Off-Grid System also called as Stand-Alone Power System is not linked to the electricity grid. It is common in far-off and remote areas where the electricity grid mains power is not available. To help balance any shortage or excess in the generation of energy, batteries are used for backup as well as storage.
Another source of energy supply like an electric generator is connected with the system to ensure an uninterrupted supply of power; if in a rare case solar panels are unable to generate energy or batteries get discharged.
Hybrid systems are connected to the grid as well as have battery storage and backup. In this system, instead of sending excess power back to the grid, it is stored for use during peak demands or low energy generation due to less or no sunlight. This highly advanced system provides its users with a constant supply of steady, economical, and eco-friendly electricity.
