INDIRECT OFF-GRID SYSTEMS

Solar energy is a very important alternative energy source for rural areas where setting up conventional electricity network faces obstacles.

Single solar modules - or an array of them - convert sunlight directly into electrical DC power. This DC power is stored in a battery and can be used at any time to supply electricity to consumers. A mandatory charge regulator monitors the status of the battery, an optional inverter may convert the DC current into AC.

There are mainly three categories of these off-grid-systems:

1. Solar home systems with a typical size of 30 … 200 Wp
   
   Conventional electricity grid will not reach all people in the developing countries in the foreseeable future.
   
   To decide on the system that will meet your needs, we will ask you to determine the power requirements. Together, we will create a list of all the loads, their power and their daily hours of operation. We will be glad to design the proper components for you.
   
   
   
2. Stand alone for rural areas with a typical size of 300 Wp … 3 kWp
   
   Particularly photovoltaics can contribute to the provision of electricity for remote areas, we can light villages with PV mini-grids and solar based hybrid systems, which include a wind turbine or a back-up diesel generator.
   
   These PV-systems need professional technical assistance during planning, choice of components and on-site installation to match your needs and wants with the technical and economical possibilities. Our experience in calculating numerous systems around the world guarantees the proper functioning of your energy supply. Our choice of high quality assemblies ensures that your system is safe, reliable and cost-effective.
   
   
   
3. Professional applications with a typical size of 1.5 kWp … 30 kWp
   
   Due to higher initial investment costs, photovoltaics are often considered more expensive than conventional diesel generators to power remote electrical applications. But spreading the entire costs of investment, maintenance, lifetime, fuel and costs of refueling over a span of 10 or more years, solar modules are much more cost-effective and reliable.
   
   We have already powered repeater stations for telecom-companies in Europe, Middle America and Asia or SCADA Systems for pipelines in Africa. Our engineering and installing expertise assures you the best possible solution and state-of-the-art technology.
