Solar PV Components
SOLAR CHARGE CONTROLLER
Solar charge controller/regulator: Solar Module is not equipped with a mechanism to detect if the battery is full and, neither is the battery set to reject electricity from the module when it is full.
The two problems are taken care of by a device known as solar charger controller/regulator. This is a device protects the battery from being overcharged by solar module and deeply discharged by electrical loads. It is also used as the the monitoring device for the system to the end user.
SOLAR POWER INVERTER
Solar Power Inverter (Battery Inverter): Mostly, electricity used in homes and working places is of alternating current (ac) type while solar module generates direct current(dc) electricity.
The solar batteries store and supply dc type electricity.For DC electricity to be converted to ac type, a device known as inverter is required. Inverters are electronic devices designed to change dc electricity into ac electricity in standard voltages and frequencies so that they can be used to run ac electrical loads.
STAND ALONE SOLAR PV SYSTEMS
Stand-alone solar PV systems are designed to operate independently, and comprises of solar module/panel, solar battery, solar charge controller/regulator and where ac power is needed inverter is also connected. Most of stand-alone systems are used in remote/rural areas where grid electricity is not nearby and running a generator is cost prohibitive.
Our stand-alone systems are well engineered to suit the need of electricity requirements in homes, schools, clinics, lodges etc, to power various electrical loads such as lights, television, radio, phone charging, refrigerator etc.
The capacity of the system depend on how much energy is needed per day, hence it is crucial for solar engineer/technician to know how much power is going to be needed and when it will be called for and for how long, so that he/she can design and size properly your solar PV system.
It is important therefore, for the prospective user to list down electrical appliances he/ she intending to use, their power consumption and daily average hours of use. It should be noted that the higher the energy demand the bigger the system and vice-versa.
