Circulates Refrigerant: Moves refrigerant throughout the system.

Compresses Gas: Raises pressure and temperature of refrigerant.

High Energy Use: Consumes the most electricity.

Key to Efficiency: Essential for overall system performance.

As the refrigerant flows through the evaporator, it absorbs heat and changes from a liquid to a gas.

low Regulation: Controls refrigerant flow in the system.

Pressure Reduction: Lowers the pressure of the liquid refrigerant.

Rapid Cooling: Causes refrigerant to expand and cool.

Cycle Continuation: Cooled refrigerant flows to the evaporator to restart the cycle

Solar Panels: Convert sunlight into electricity.

Key Technology: Essential for renewable energy transition.

Improved Efficiency: Significant advancements in recent years.

Solar Cells: Basic units of a solar panel.

Material: Usually made from silicon.

Electric Current Generation: Sunlight knocks electrons loose, creating current.

Panel Formation: Multiple cells are connected to form a solar panel.

Glass Covering: Protects solar cells from the elements.

Material: Typically made of durable tempered glass.

Weather Resistance: Withstands harsh conditions.

Advanced Features: Some use anti-reflective glass for better light absorption.

Location: Attached to the back of the solar panel.

Function: Houses the panel's electrical connections.

Current Exit Point: Wires carrying electric current exit the panel here.

Bypass Diodes: Modern junction boxes often include these to maintain performance when part of the panel is shaded.

Optimal Angle: Panels should be tilted at an angle that maximizes sunlight exposure, typically around 30-40 degrees in the UK.

Orientation: Ideally face south to capture the most sunlight throughout the day.

Avoid Shade: Position away from trees, buildings, or other obstructions that cast shadows.
