Today photovoltaic (PV) systems offer an attractive solution for an ever increasing number of applications that demand an economic and reliable power supply - even under extreme environmental conditions.
Solar modules generate electricity from sunlight in a particularly environmentally friendly way. Their operation pollutes neither air nor water and is completely silent. Even after many years of operation, they continue to supply energy.
Solar-generated electricity can supply autonomous power in rural areas, or can be linked to the grid. In developing countries, PV systems are already responsible for the wide-spread supply of clean water and safe electricity.
Glass, silicon and aluminum, the main components of the solar modules, can be processed by a recycling plant.
Solar systems begin with the solar module. Modules gather solar energy in the form of sunlight and convert it into direct current (DC) electricity. The more sunlight they receive, the more electricity they produce. Solar modules are the heart of the system. They are the power generators.
Components such as charge regulators, batteries and inverters regulate, store, condition and deliver the electricity. Other elements connect the different components of the system.
Solar systems have to meet high standards of reliability and economic efficiency. This can only be guaranteed by the use of field-proven quality components that are well-matched.
| Sunlight | Sunlight is energy in the form of light. It is the fuel of a solar (PV) system. |
 |
|
| Solar Module | Solar modules generate DC electricity directly from sunlight. Use one or more modules depending on your power needs and the amount of sunlight |
|
|
| Charge Regulator | Charge regulators are the link between the modules, battery and load. They protect the battery from overcharge or excessive discharge. |
|
|
| Battery | Batteries store the energy generated by the solar modules. |
|
|
| Inverter | Inverters convert DC (direct current) electricity into AC (alternating current) to run many common appliances and equipment. |
|
|
| Mounting Structure | Mounting structures hold the solar modules securely in place. Ground, roof and pole mounting versions are available. |
|
|
| Load | The appliances, lights and equipment being powered are called electrical 'loads.' Energy-efficient loads contribute to overall system efficiency and economy. |
|
|
| Wiring / Interconnects | Proper wiring and connections must be specified for every segment of the system to assure best performance. |
|
|
| Back-up Generator | Compatible generators (i.e. diesel) may be used as back-up for excessive power demands or during unanticipated long sunless periods. |
|
|
| Space | Solar modules should be installed in an area that is generally free from shade and receives as much direct sun exposure as possible. |
|
|
| Maintenance | Solar systems are one of the easiest and most reliable ways to generate electricity. Regular maintenance to check wiring, connections, batteries, and overall system condition will help assure long-term trouble-free operation. |
