PV Systems

On-Grid Solar System
A. Net Metering: Also known as a grid-tie or grid feed solar system. The system is connected directly to the electricity grid, it doesn’t need batteries and use common solar inverters.

B. Wheeling System: Wheeling is the transfer of electrical power via a utility’s transmission or distribution system between different grid or network service areas. When it comes to solar PV, the areas where the sun is most powerful and consistent is often geographically separate from the urban hubs where electricity is required.

Off-grid system
Also known as a stand-alone power system (SAPS). off-grid system is not connected to the grid and therefore requires battery storage. It must be designed appropriately so that it will generate enough power throughout the year and have enough battery capacity to meet user’s requirements, even in the depths of winter when there is less sunlight.

Pumps
A solar-powered pump is a pump running on electricity generated by photovoltaic panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity or diesel run water pumps. It can be used for agriculture irrigation, pasture animal husbandry, seawater desalination, living water supply and so on. The system is easy to install and move, environmentally friendly and has many economic benefits.

Hybrid System
Solar plus battery storage with grid-connection. Modern hybrid systems combine solar and battery storage in one and are now available in many different forms and configurations. Due to the decreasing cost of battery storage, systems that are already connected to the electricity grid can start taking advantage of battery storage as well. This means being able to store solar energy that is generated during the day and using it at night. Hybrid systems are also able to charge the batteries using cheap off-peak electricity (usually after midnight to 6am).
