Introduction to Solar Panels

Solar panels, also known as photovoltaic (PV) panels, are devices that convert sunlight directly into electricity. They are composed of multiple solar cells made from semiconductor materials, typically silicon, that absorb photons and release electrons, thereby generating an electric current.

Functionality of Roof-Mounted Solar Panels

Roof-mounted solar panels work by harnessing solar energy and converting it into usable electrical power. The solar cells on these panels capture sunlight and initiate an electric current due to the photovoltaic effect. This DC current is then converted to AC current by an inverter for household or commercial use.

• Photovoltaic Effect: Responsible for generating electricity from sunlight.
• Inverter Efficiency: Modern inverters convert DC to AC with efficiency rates up to 98%.
• Output Parameters: A typical residential solar panel has an efficiency between 15-22% and can generate between 250-400 watts of power.

Installation Process

The installation of roof-mounted solar panels involves several steps to ensure optimal energy production:

1. Site Assessment: Evaluation of roof condition, orientation, and shading influences.
2. Design Planning: Calculating panel placement and energy needs. Typical installations require 20 to 25 panels for an average home, covering 400 to 650 square feet.
3. Mounting System Installation: Use of rails and brackets to secure panels on the roof.
4. Electrical Wiring and Inverter Setup: Connecting panels to an inverter and the building's electrical system.
5. Inspection and Activation: Ensuring safety standards are met before turning the system on.

Factors Affecting Efficiency

Several factors can influence the performance of roof-mounted solar panels:

• Sunlight Intensity: Direct sunlight maximizes power generation, with geographic location being a crucial determinant.
• Panel Orientation: Optimal orientation is towards the equator, with a tilt angle that maximizes yearly sun exposure.
• Temperature: High temperatures can decrease efficiency; panels are rated against standard test conditions of 25°C.
• Shading: Even partial shading can significantly impact output, with some panels losing up to 50% of their efficiency when a section is shaded.
