How do photovoltaic (PV) cells work?

PV cells are panels you can attach to your roof or walls. Each cell is made from one or two layers of semiconducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced.

PV cells come in a variety of shapes and colours, from grey “solar tiles” that look like roof tiles to panels and transparent cells that you can use on conservatories and glass.

The strength of a PV cell is measured in kilowatt peak (kWp). That’s the amount of energy the cell generates in full sunlight.

SGAS Solar Photovoltaic Course (up to 5kW)

This course will give candidates detailed explanations & practical examples of selecting, installing and commissioning solar photovoltaic systems.

Completing the course and assessment will allow candidates to apply to an MCS Scheme provider (microgeneration certification scheme) such as NICEIC, NAPIT, ELECSA or CORGI.  Where grant funding is not available for the installation, the course and assessment will allow candidates to notify the installation as a ‘controlled service’ via LBC (Local Building Control) in the usual manner.

A sound knowledge of electrical installation requirements and standards, together with inspection & testing experience is an advantage for candidates undertaking this course and assessment.

The course content includes the following:-

· Regulations & Standards

· AC & DC Theory

· Cell Types and benefits

· Circuit Design

· System Design & Integration

· External & Internal Site Survey Requirements

· Setting to work and commissioning

· Servicing & Fault Finding
