Solar panels convert sunlight into electricity through photovoltaic cells. These cells, typically made of silicon, absorb photons from sunlight, exciting electrons and creating an electric field. This process, known as the photovoltaic effect, generates direct current (DC) electricity. Inverters then convert DC to alternating current (AC) for use in homes and businesses.
Solar panel systems comprise multiple components, including modules, mounting structures, and wiring. Different types of panels exist, such as monocrystalline, polycrystalline, and thin-film, each with varying efficiencies and costs. Understanding the intricacies of solar technology reveals its potential for sustainable energy production.

A solar PV system comprises several key components that work together to generate and distribute electricity. At the heart of the system are solar cells, which convert sunlight into electrical energy through the photovoltaic effect.
Inverters play a crucial role in converting the direct current (DC) produced by solar cells into alternating current (AC) suitable for household use, while the decision between grid-tied and off-grid systems determines how the generated electricity is used or stored.
Central to the functionality of solar PV systems, solar cells serve as the fundamental units responsible for converting sunlight into electrical energy through the photovoltaic effect. These semiconductor devices, typically made from silicon, form the core of solar panels.
Key characteristics of solar cells include:
Solar cells are meticulously encapsulated and housed within protective layers, ensuring best performance and longevity in various environmental conditions.
Integral to solar PV systems, inverters serve as critical components responsible for converting the direct current (DC) electricity generated by solar panels into alternating current (AC) suitable for household use and grid integration. These devices maximise energy efficiency and ensure compatibility with appliances.
Various types, including string inverters, microinverters, and power optimisers, offer unique benefits. Proper sizing, installation, and monitoring of inverters are essential for optimal system performance and reliability.
When considering solar photovoltaic (PV) systems, understanding the distinction between grid-tied and off-grid configurations is essential for determining the most suitable setup based on location, energy needs, and desired level of independence from the utility grid.
