Our Solar Residential & Home Systems Include:
Classical Solar Home Systems generally cover a power output of up to 200W peak. They are normally composed of several independent components: modules, charge controller, battery and the loads. The overall energy management is done by the charge controller as the central component of the system. Important advantages of classical SHS are the DC loads like DC energy saving lamps, radios, DC TV and special DC fridges directly usable by the system. This makes SHS very energy efficient systems without any conversion losses. For bigger SHS, the integration of AC loads is possible with the use of a DC/AC inverter, however these loads are often inefficient and oversized and thus can have a long-term impact on the storage capacity, which might be quickly damaged if let in a state of permanent deep discharge.
Consequently, it requires good design and the use of an optimized charging technology. However, trained technicians for the installation and suitable operation and maintenance will easily allow the SHS to provide reliable energy supply for years.

Larger stand-alone PV systems are called Solar Residential Systems (SRS). They usually provide electricity to large individual installations like hotels, hospitals, schools, factories etc. and offer a wide range of applicable loads. They generally include an inverter allowing the use of AC loads. The use of AC power has certain advantages, but should be primarily reserved for larger systems and/or if the loads needed can only be operated with AC power (e.g. larger working instruments and machines). With a typical range from 500W to 4000W output power, SRS usually integrate 12V and 24V battery voltage, even if bigger systems work with higher voltage (48V).

Many independent power systems use more than one source of energy and thus are called hybrid systems. Most of the hybrid systems use PV in combination with a wind generator and optionally a diesel generator for the back-up-function. Hybrid systems ensure a continuous and reliable electricity supply. They also provide enough power to satisfy modern domestic needs (lighting, communication, refrigeration, water supply) as well as public services (health centres, schools) and the development of a local economy (small industries and related services such as telecommunication towers and water irrigation systems). Hybrid systems can also be used for centralized village power supply by serving a mini-grid.

The size of Off-Grid street lighting systems are comparable to the size of Solar Home Systems. A typical street lighting system consists of solar modules, MPPT charge controller, batteries and the DC street lamps. The common lamps are low pressure sodium (SOX) or light emitting diodes (LED).
Benefits:
Modular linear installation along the street, each light unit is an independent entity
No costly expenditure for underground or above ground cables to be purchased and laid
GSM programmability and monitoring
Fully automatic operation
Environmental benefits (clean energy)
