Harnessing energy from the sun is not as complex as it might seem. However, it does require a team of special devices which work together to generate free and clean solar energy. Different parts together make up a solar rooftop system wherein each part has specified functions and roles.
Here are the components that together make up a solar rooftop system
Photovoltaic (PV) Panels
Solar panels or PV panels are the chief components of any solar power system let alone a solar rooftop system. Solar cells present in the panels absorb the energy from the sun and convert it into direct current. These are made of silicon crystals and nowaday thin-film solar panels are also available in the market.
Inverter
To call it, an inverter is the brain of a solar power system. There are two functions of an inverter;
To convert DC power generated from solar panels into AC power so that our electrical and to make sure that solar power generated is used at priority over grid supply.
Batteries
Batteries are in a solar rooftop system serves two purposes; to store the power generated by the solar panel system and to make the power available to the solar panel system if the grid is not supplying it.
Solar Charge Controller
A charge controller controls the rate of electric current drawn by the batteries. The primary function of a charge controller is to block reverse current and prevent your batteries from getting overcharged charging. They are available in stand-alone mode or are integrated with a controlled circuitry with a battery pack or battery charger.
Electric Meter
With grid-tied solar rooftop power systems, electric meter is installed which measures the energy consumed by your house and the amount of energy that is sent to the grid. It plays an important role in the net metering mechanism.
Main AC Board
This is where all the electric loads in the building are connected and protected with circuit breakers. Once the output from the PV system has been converted to AC power, it can be connected to the main panel to provide energy along with the electric utility.
Safety Equipment
Solar panel parts and components are connected by cables on DC and AC side. It is also important to install safety equipment since PV systems are designed for long life use. Electrical surges or short circuit can damage the equipment. Proper earthing, surge protectors, lightning arrestors, etc. are required.
The components of every solar power system are similar all across the world. However, based on the region of your residence, the type of these components used may vary. Solar power systems have a long life. Therefore, it is important to emphasize on quality and safety for durable performance.
