Siemens AG

Siemens Photovoltaic Solutions for Today and Tomorrow

The solar park in Les Mées, France, 31 MWp, provides electricity for more than 12,000 households.

Siemens covers the entire PV value chain: from glass and silicon materials to module production, field installation, inverters, integrated automation systems and as a supplier of turnkey large-scale PV arrays.

We are shaping a green and sustainable environment for future generations

Siemens is a global powerhouse in electronics and electrical engineering, operating in the fields of industry, energy and healthcare as well as providing infrastructure solutions, primarily for cities and metropolitan areas. For over 160 years, Siemens has stood for technological excellence, innovation, quality, reliability and internationality. The company is the world’s largest provider of environmental technologies. Around 40% of its total revenue stems from green products and solutions. At the end of September 2011, Siemens had around 360,000 employees worldwide, based on continuing operations.

Utility-scale photovoltaic power plants

Siemens is actively engaged in the fields of Engineering, Planning and Commissioning (EPC) utility-scale photovoltaic power plants. As a general contractor, Siemens provides its customers with large-scale rooftop and ground-mounted arrays. The focus here is on customized solutions and overall optimization of the photovoltaic plants, with the goal of achieving the lowest power generation costs with the greatest degree of safety, reliability and return.

For the turnkey installation of PV power plants, Siemens supplies in-house manufacturing components such as inverters, transformers and medium-voltage switchgears, and combines these with PV modules from bankable suppliers and products from local markets. In addition, Siemens also offers a unique layout planning system for utility-scale PV power plants in its portfolio: It combines specific plant requirements with Levelized Cost of Electricity (LCoE)-optimized concepts.

Applying a contract model in which the Performance Ratio (PR) is anchored, the efficiency and defined performance data of a solar plant can be guaranteed over the entire life-cycle of the plant.

Maintenance and feasible solutions for solid financing are services that round out the Siemens portfolio. A selection of different service packages is available for the operational phase. Particularly worth mentioning is the performance ratio guarantee, which minimizes financial risk for the plant operator and investors. In conclusion, Siemens offers technically optimized plant designs with only best in class products to guarantee the highest plant performance while safeguarding the customers’ investments over the whole lifetime of the plant.

SINVERT – photovoltaic inverters from Siemens

With their high level of availability and optimized efficiency, SINVERT inverters provide a reliable basis for operating a photovoltaic plant efficiently throughout its entire life-cycle. SIEMENS PV inverters, with their peak efficiency of > 98%, are available for a broad market spectrum (commercial and power plants). The functions and yield of the entire photovoltaic plant can be monitored and visualized in a user-friendly fashion using SINVERT WebMonitor or SIMATIC WinCC industrial software. Complimentary SINVERT Select layout software is available for determining the optimum configuration for a PV plant.

SINVERT PVM inverters are available in the range from 10 to 20 kW for small to medium-sized plants in the “commercial” market segment. The three-phase inverter series is characterized by its compact design, its robust quality and its long service life.
