Are solar panels and photovoltaics the same?

The broad category of solar panels includes photovoltaic cells but is not the same thing. While photovoltaic panels are a type of solar panel, solar panels can also include solar thermal panels, which generate power using the heat from the sun as opposed to light.

What is the difference between photovoltaic and solar thermal panels?

While photovoltaic panels are a type of solar panel, solar panels can also include solar thermal panels, which generate power using the heat from the sun as opposed to light. PV systems convert energy using cells with semiconductors, while solar thermal panels utilise tubes filled with a liquid (often glycol) with antifreeze to capture heat.

What is a solar photovoltaic system?

Solar photovoltaic systems have been around for multiple decades, using the "photovoltaic effect" to absorb sunlight. This phenomenon was first utilised by scientists at Bell Laboratories with silicon solar photovoltaic cells. Since then, the technology has progressed rapidly, powering everything from satellites to entire homes.

What is the photovoltaic effect?

The core technology behind these systems is the photovoltaic effect. This is a process that begins when sunlight hits a solar panel that’s typically made from semiconductor materials like silicon.

Are polycrystalline panels better than photovoltaic panels?

Polycrystalline panels are easier and cheaper to produce but they also take up more space. A similar form of photovoltaic technology. This one uses thin layers of semiconductor material, (often cadmium telluride or copper indium gallium diselenide) that is only a few micrometres thick.

Which solar panels are best?

SunPower is onto another winner with its Maxeon 3 panels, whose appearance and specs are similar to the Maxeon 6 AC, but without the individual micro-inverters. The panel has a brilliant efficiency rating and, like the Maxeon 6 AC, is made from recycled materials.
