Photovoltaic cells and solar heating panels.

Solar panels consist of smaller units which we also refer to as photovoltaic cells. While a single photovoltaic cell is able to convert sunlight into electricity on its own the panel is essential to combine and direct the energy output of numerous cells to your inverter and home. As it circulates through the exchanger the water warms up by recovering the heat emitted by the photovoltaic cells. This means that solar panels are only effective during daylight hours because storing electricity is not a particularly efficient process.

There s a complex relationship at work between photovoltaics pv heat and sunlight. Solar power works best when the sun s shining of course. A solar pv panel works in a way that allows light particles or photons to heat electrons from atoms which in turn generates a flow of electrical power. Photovoltaic modules are tested at a temperature of 25 degrees c stc about 77 degrees f and depending on their installed location heat can reduce output efficiency by 10 25.

Solar thermal technology and solar pv are two very different forms of solar technology. But when the sun s shining everything gets hotter. As the temperature of the solar panel increases its output current increases exponentially while the voltage output is reduced linearly. The cooling agent i e water or air is circulated around the pv panels for cooling the solar cells such that the warm water or air leaving the panels may be used for domestic applications such as domestic heating.

It may seem counter intuitive but solar panel efficiency is affected negatively by temperature increases. This water can reach a temperature of up to 70 c and can therefore be used to cover the building s various heating needs. As the name may suggest to you solar thermals technology is used to create heat for your home. Photovoltaic cells are the main component that makes up a solar panel while solar panels are a vital component that makes up a solar system.

Sunlight is collected as it would be via regular solar panels before being transformed into heat for water or your home in general.
