. How your Conergy Solar Power System Works
Solar energy is renewable and is different from conventional power generation in that:
| You are using environment friendly energy which doesn’t need big, pollution emitting power stations.
| It can also be generated on a small scale like on your rooftop.
| Once the solar power system is installed it costs you nothing to generate electricity.
Solar electricity generation works by converting energy from the sun, in the form of light, into electricity. Please note
that only light and not heat is transformed into electrical energy. Heat from the sun will have an adverse effect on
power generation as it slightly reduces the efficiency of solar cells.
Solar cells are made of semiconductors and work via what is known as the photovoltaic (PV) effect. In this process
when light hits a conductor and semiconductor it transfers its energy to that conductor. Light is actually a stream of
energy particles called photons. When the photons hit the silicon surface in the solar cells they generate electricity by
transferring energy and freeing electrons. In this way electricity is generated. Put simply, photovoltaic cells are energy
converters - converting the energy from sunlight into electricity.
Solar modules usually contain multiple number of solar cells encased in a durable casing. Toughened glass is used
to cover and protect the solar cells and a antireflective coating is used to minimise light reflection from the surface.
Solar modules produce DC power, usually at 12V or 24V. The inverter included in your Conergy SunEasy solar power
system converts DC power to AC power and feeds it into the electricity grid, if not used in your household directly.
With this setup, if you are using less power than you are producing, your meter runs backwards. If you are using
more power than you are generating your meter runs forwards. Some utilities require that you install two independent
energy meters. One to measure your consumed energy and the other for metering the amount of electricity your
system has returned to the grid. Your energy retailer will credit/charge you the difference between your consumed
energy and your generated energy.
