The functioning of solar energy

How does it actually works?

If you’re considering installing a solar panel at your location, you’re probably repeatedly pondering the most common question: How does it work? How does it capture the sun’s energy and generate electricity?

How Solar Energy Works?


Solar panels, alternatively referred to as Photovoltaic panels, solar modules, and Photovoltaic modules, harness sunlight by absorbing photons, generating an electric field across their photovoltaic cell layers, and thereby generating electricity. This electricity is then utilized to power households.

The photovoltaic effect makes this achievable. “Photo” from Greek signifies ‘Light,’ while “Voltaic” denotes electricity generation. This not only leads to significant savings on electricity expenses but also contributes to environmental preservation. Solar panel-generated power leaves no waste, ensuring complete safety.


Solar Panels – Capturing Sunlight Rays

When sunlight’s photons hit the solar panel, electrons within the photovoltaic cells become energized, initiating a flow that generates an electric field, producing raw electrical power, also recognized as direct current (DC) power. Constructed from high-quality silicon material, solar panels rely solely on sunlight for operation.


Inverter – Conversion Of DC Power Into AC Power

The power generated is in the form of DC power. However, since most household appliances run on Alternating Current (AC) power, an inverter is necessary to convert the DC power into AC power, aligning with household needs. This AC-DC inverter operates automatically, deactivating at night and restarting when sufficient sunlight is available.


Isolator – Protection From Over Currents

An additional AC Isolator Switch is essential for linking the Solar Power System to the current infrastructure, safeguarding equipment from potential damage caused by overcurrents originating from a faulty inverter.


Power Meter – Net Metering

The converted DC power is transmitted to your home and integrates with the AC power provided by the local grid at the Home’s Main Meter panel. Typically, older power meters are replaced with new bidirectional digital power meters known as Net Meters during the installation of a solar power system. Consequently, the home functions as a miniature grid, generating its own electricity and potentially supplying excess power to the local grid. Net metering monitors the net electricity inflows and outflows throughout billing cycles. Customers are billed for the electricity they consume, subtracting any surplus power sold back to the local utility company.


Distribution Panel – Electric Power Delivery

Electric power is delivered to the home via the existing wiring system, illuminating the household and powering essential appliances such as the AC, washing machine, and refrigerator. Installing a Solar (PV) energy system at your residence will generate clean, environmentally friendly, and sustainable energy, significantly lowering your energy expenses.
