There are three primary technologies by which solar energy is harnessed.
Solar panels information technology.
Solar technologies convert sunlight into electrical energy either through photovoltaic pv panels or through mirrors that concentrate solar radiation.
The second technology is concentrating solar power or csp.
This energy can be used to generate electricity or be stored in batteries or thermal storage.
A comparison of a standard solar panel installation l and solar skins on top r.
A single pv device is known as a cell.
Many are familiar with so called photovoltaic cells or solar panels found on things like.
And solar heating and cooling shc systems which collect thermal energy to provide hot water and air heating or.
Monocrystalline and polycrystalline solar cells mono and poly for short.
Solar skins are a novel pv technology to integrate custom designs into solar panel systems.
The solar skin technology is similar to the ad wraps displayed on bus windows.
When the sun shines onto a solar panel photons from the sunlight are absorbed by the cells in the panel which creates an electric field across the layers and causes electricity to flow.
As of 2011 the technology produced less than one tenth of one percent of global energy demand.
Solar pv technology captures sunlight to generate electric power and csp harnesses the sun s heat and uses it to generate thermal energy that powers heaters or turbines.
An individual pv cell is usually small typically producing about 1 or 2 watts of power.

Monocrystalline solar panels have solar cells made from a single crystal of silicon while polycrystalline solar panels have solar cells made from many silicon fragments melted together.
Other major events in the history of solar energy.
The main difference between the two technologies is the type of silicon solar cell they use.
Massachusetts institute of technology mit news.
There are two main types of solar technology.
Concentrating solar power csp which uses heat from the sun thermal energy to drive utility scale electric turbines.
Pv materials and devices convert sunlight into electrical energy.
These are the panels you ve seen on rooftops or in fields.
Photovoltaics pv which directly convert light to electricity.
There are two established cell technologies that dominate the market.
In 1958 the vanguard i satellite used a tiny one watt panel to power its radios.
Mono cells are cut from a single source of silicon while poly cells are made by blending multiple bits of silicon into a single cell.
