12v 40watts Monocrystalline Solar Panel With Aluminium Frame
1> Quick Detail:
2> Description:
The solar cells are extremely thin (normally about 0.3 mm) and are thus highly sensitive and must be protected against external influences. For this reason the cells are installed in a PV solar panels. The PV solar panels consists of a hardened sheet of glass behind which the cells are lined up. At the rear the cells are protected by a layer of plastic. The electrical connections of the cells are fed out of the module to a junction box.
PV solar panelss generate DC current as soon as the sun shines on them. This has to be converted into AC current if the solar system is to feed into the house mains. The inverter is the component which converts the DC current into AC current. The inverter also performs other tasks.
There is an operating point at which the PV solar panelss supply the most energy. This Maximum Power Point (MPP) depends on the light intensity and the temperature of the PV solar panels. During operation of the solar system the inverter continuously searches for the MPP and adapts the current and the voltage of the PV solar panelss such that maximum power is always fed into the mains. The inverter also monitors the mains connection and thus also ensures fault-free parallel operation with the public electricity network.
For the winning of energy from sunlight the angle of the PV solar panels to the sun and how the sun shines on it play an important role.
If the sun is hidden behind clouds or if part of the PV solar panels is in the shade or is dirty then the energy yield is low. For this reason it is important to ensure correct alignment of the module and to make sure that no shade falls on it. It is also important to ensure that the mounting angle of the module is sufficiently large to allow adequate self-cleaning via rain running off it.
The PV solar panelss are installed on the roof in such a way that as much energy as possible can be generated. Most slanted roofs which point south are suitable for the installation of solar systems. A roof inclination of between 15 and 50?is optimal, taking into consideration the points referred to above.
Structures on the roof such as chimneys and skylights must in all cases be considered by the specialist during the planning of the system.
A typical solar power system requires approx. 10 to 30 m?of the roof area. If the solar power system is aligned southwards and installed by specialists an annual yield of 850 kWh per installed 1 kWp can typically be achieved in Germany.
The solar energy used is in proportion to the nominal yield which can be generated and is therefore suitable for comparing different systems.
