Site development   Once a site has been shortlisted, Solar Cells Hellas (SCH) deliver detailed reports on aspects such as solar irradiation and the soil conditions to enable precise costing of the project. Meanwhile, the technicalities of feed-in are clarified with the local power utility. Parallel to these site analyses, SCH also takes care of the obtaining official approval. Once this has come through and the finance has been settled, detail planning can begin.   Planning   A project is implemented in the following stages: planning, contraction, start-up and servicing. This is one of the reasons why large-scale projects of around 50Mw can be accomplished within just few months. During the planning phase, the electrical equipment and the rack systems are adapted to the specific conditions on site, while the project timetable and logistics are defined. This is to ensure that the components necessary are available at the right time and that the various stages of construction are seamlessly scheduled.   Construction   During construction, SCH makes use of an established network of subcontractors. This reduces the time and recourses required for project control and minimize the involved risks. Building begins with the foundations in the soil for the rack systems which will accommodate the modules. Next, all the electronic components are fitted. After, a standard unit has been completed; it is time to install the inverters, whose job it is to convert current produced into the alternating current required by the grid. The use of state-of-the-art equipment enables high efficiency.   Start- up   Following the completion of individual units, pv power systems are directly connected to the power utility' s network. When the final unit has been connected, the pv system is ready for handover to the client.   Servicing   In most projects, the servicing and operation of the solar power system are curried by SCH to offer the project partners maximum reliability. Extensive insurance packages are used to cover all the risks and the systems' maximum technical availability is guaranteed throughout its lifetime.
Technical Components   SCH's clients profit not just from company's all-round services but also the reliability of the used components. When assembling pv systems, SCH uses an established network of proficient subcontractors working together effectively. A solar power system comprising high-quality components guarantees dependable returns throughout its service life. Low maintenance cut costs and makes the system an attractive investment. SCH keeps it in full working order for its entire lifetime.   PV Modules   Sunlight is turned into electricity in pv modules. Cells made out of crystalline silicon are used. Inside each module, the sunlight generates electrical current, which is tapped on the surface. As the modules' quality and efficiency affect the entire array, SCH is optimally equipped with major technology products.   Inverters   The direct current produced by solar modules has to be converted into alternating current before it can be fed into the electricity grid. A suitable inverter quickly and precisely adapts to changing irradiation conditions to maintain high efficiency. SCH only uses inverters made by the world's leading suppliers.   Mounting system   The mounting system makes sure the modules are attached securely and permanently in all areas and under all conditions. SCH uses mounting systems made by established partners with a user – friendly design for quick construction. The high quality of the mounting system guarantees durability.
Benefits of a Solar Power System   -  Low maintenance costs   Apart from cleaning, tending greenery and occasionally replacing very small components, hardly any maintenance or servicing costs are incurred for a pv array throughout its operational life.   -  Rapid construction   Compared to conventional power plants, thanks to efficient planning and standardized building processes, a large-scale solar array can be up and running in next to time. This is partly due to the hiring of tested partners and suppliers and the high degree of system standardization.   -  100% scalable and modular   The size of a solar array is also scalable. Combined with a modular design, solar power systems are flexible and easily adapted to changes.   -  Double returns   Feed-in tariffs enable returns on investment a short time after start-up. Due to above-average financial performance, both operators and investors profit.
