The Solar home power system
Solar power is an abundant and renewable energy from the sun. The Solar Photovoltaic Generation is an innovative and highly developed technology, which can convert solar radiation or light energy into electricity. It's very clean, pollution free and renewable. Making full use of solar power will promote balance between humankind and nature.
Solar power has many advantages:
· Safe · Available everywhere · Without noise · Pollution free · Solar systems have long lifetime, no matter in large or small scale · There is no need for fuel · The equipment is easy to install and is without wire connections · Easy to maintain.
All the above mentioned advantages are unique to solar power when compared to the conventional ways of generating electricity. Photovoltaic (PV) is the technology of converting solar radiation or light energy directly into electricity.
The principle is that when sun light meets the PV solar panel, an electric current and voltage will appear. This electric current is then converted into electricity and stored in a battery for later use. The solar power systems consist of solar panels (PV arrays), a controller, storage batteries and a DC/AC inverter.
The maximum power point of the system is mainly affected by the ambient temperature and the intensity of sunshine. When the intensity of the sunshine is constant, the maximum output power decreases with the rise of the temperature. When the temperature is constant, but the sunshine intensifies, the open circuit voltage of the PV battery basically remains unchanged but the short circuit current increases substantially, thus the maximum output power increases substantially
