What are photovoltaic panels?

Photovoltaic (PV) panels are devices that convert sunlight into electrical energy using semiconductor materials. This process is known as the photovoltaic effect. PV panels are an essential component of solar power systems and are increasingly being deployed for both residential and large-scale power generation purposes.

Which direction should a photovoltaic module be installed?

When installing photovoltaic modules in the northern Hemisphere, the optimal installation direction of the module is to face south; When installing photovoltaic modules in the Southern Hemisphere, the optimal installation direction of the module is to face north. Serial connected PV modules should be installed in the same orientation and Angle.

What are photovoltaic panels & how do they work?

Photovoltaic panels, or solar panels, are the most crucial component of a solar power system. They are responsible for converting sunlight into direct current (DC) electricity through a process called the photovoltaic effect. Solar panels are made up of many individual solar cells, which are usually made from silicon, a semi-conducting material.

How should a PV system be designed & installed?

From the outset, the designer and installer of a PV system must consider the potential hazards carefully, and systematically devise methods to minimise the risks. This will include both mitigating potential hazards present during and after the installation phase.

Can a PV system be electrically installed?

Guidance exists for electrical installation of PV systems[15, 16, 17] but there is little equivalent guidance for mechanical installation.

How do you install PV panels on a house?

The most common method of installing domestic PV panels is mounting them to your rafters. This is done with custom hooks, aluminium mounting frames and specialist clamps. When a property is over one storey high, scaffolding is essential to gain roof access as the engineers need access to work on the roof.
