Understanding How Solar Systems Work
Before diving into the technical procedure, it is important to understand how a solar power system, explained in practical terms, actually functions.
Solar panels capture sunlight and convert it into direct current (DC) electricity using photovoltaic cells. That DC electricity is then converted into usable alternating current (AC) electricity via an inverter. The energy can either be consumed instantly, stored in batteries, or exported to the grid, depending on system design.
Role of Solar Energy and Panels
The efficiency of solar energy and panels depends on:
• Sunlight exposure
• Panel orientation and tilt
• Temperature conditions
• Dust and environmental factors
• Quality of installation
Proper system design ensures maximum generation throughout the year.
Essential Components in a Solar Installation
The Essential components required for a properly functioning solar system include:
- Photovoltaic modules – These panels convert sunlight into direct current (DC) electricity using solar cells.
- Mounting structures – These frames securely hold the solar panels in place at the correct angle for maximum sunlight exposure.
- DC and AC cabling – These cables transmit electricity from the panels to the inverter (DC) and from the inverter to the main electrical system (AC).
- Earthing and lightning protection – This system protects the solar installation and building from electrical faults and lightning strikes.
- Inverter system – The inverter converts DC electricity generated by the panels into usable alternating current (AC) power.
- Circuit breakers and surge protection – These safety devices prevent electrical overloads and protect equipment from voltage spikes.
