The Science Behind Photovoltaics

Posted 18 February 2017


We’ve all heard of solar panels in 2017. But while most of us know that these eco-friendly tools turn the sun’s rays into energy, our knowledge tends to stop there. So, let’s look a little closer at the science behind the kind of photovoltaics used on Trivselhus by Esh homes.


What are photovoltaics?

The word photovoltaic means “light voltage” if we crudely translate the words from Greek. In essence, photovoltaic systems transform sunlight into a usable electrical energy.

Unlike natural gas, oil or coal, sunlight is a completely renewable source of energy, and is therefore acknowledged to be incredibly important to the future of our planet. As the damaging effects of burning fossil fuels have become clearer, so the demand for “green” alternatives has grown. And photovoltaics undoubtedly have a role to play in powering our homes as we progress further into the 21st century.

Solar modules are made up of silicon plates, which create an electrical charge when exposed to sunlight.


How are we using photovoltaics today?

As far back as the 1950s, photovoltaic energy was used in space to power satellites’ electrical systems. From those initial applications, the technology then became much more accessible. Over the years solar power had been used in everything from calculators to garden lights, by the early 2000s, they were beginning to feature on the roofs of homes around the country. 

More and more devices are being run through renewable energy and even charging stations for electrical vehicles are utilising solar power. But it is in the home that solar technologies are perhaps making the greatest difference, allowing a household to reduce their dependence on mains energy to run appliances and charge devices. In fact, it is now thought that a quarter of global energy usage could come through solar panels by 2050.


The science of solar panels

Solar panels are created by collecting solar cells, connecting them, and sandwiching them between tough panes of glass. This glass is placed within a frame and sealed. The highest quality solar panels will encase this collection of materials in order to keep out any moisture and contaminants which may result in a less productive performance from the panel.


How do Trivselhus by Esh use this science?

Trivselhus by Esh homes offer a number of “green” technologies that have contributed to us being named the What House? Sustainable Developer of the Year. In combination with other features, such as the incredible thermal efficiency of our wood-framed homes, the mechanical ventilation with heat recovery system and the air source heat pump, the solar photovoltaics on our properties deliver luxury living at its most energy efficient. 

Each Trivselhus by Esh home also features the latest A-rated appliances and LED lighting throughout, helping you to make the most of the energy harvested from the sun's rays.
