General description
PV systems are used to generate electrical energy from solar energy, which is almost unlimited and free of charge. In the solar cells of the photovoltaic modules the direct conversion of solar energy into electrical energy takes place. The generated energy can either be used on site, stored in batteries or fed into electricity grids and is sustainable, low-risk, free of emissions and climate-friendly.

  • Technical acceptance inspection of a 3.5 MW PV plant in Bulgaria
    (December 23rd, 2011)
    PROFES was commissioned by UniCredit Leasing to carry out a technical inspection after the start-up of a 3.5 MWp PV-plant in Bulgaria just before Christmas.
    Within a week this inspection was carried out and a detailed report was sent to the client.

    EVN contract to work out the submission documents for 300 kWp photovoltaic
    (December 7th, 2010)
    We are pleased that the EVN AG has again contacted us with a PV-project and has placed an order with PROFES about preparing the necessary electrical legal submission documents for two roof-mounted photovoltaic projects with a total capacity of around 300 kWp.

    Photovoltacis design contract by EVN-Naturkraft for Italy
    (June 4th, 2009)
    EVN-Naturkraft assigned PROFES to support the planning of a photovoltaics project in Italy. PROFES will be responsible for the technical concept, designing the tendering process, the medium und long term strategy and last but not least carrying out the operative tasks. Finally PROFES is responsible for calculating the profit-yield and doing the acceptance tests.

    Design contracts for a PV and a wind energy project for sites in Bulgaria
    (June 1st, 2009)
    The company Peterkom assigned PROFES to do a site evaluation for a photovoltaics and a wind energy project in west Bulgeria, Vrana. The evaluated site´s potential for photovoltaics will be up to 100 MW and in addition for at least 19 MW wind turbines.
    General Information
    PROFES supported Verbund ARP with an comprehensive technical assessment and output analysis in the take over process of 2 photovoltaic large-scale facilities. It is a 1.9 MW photovoltaic plant with an axial tracking and a 0.9 MW photovoltaic plant with a fixed elevation. Both are using polycristalline SI-Modules and a 100 kW central inverter concept.
    Technical Details
  • 2 photovoltaic plants 2.8 MWp

  • Total annual revenue of 4.8 GWh

  • 13.500 polycristalline modules

  • 100 kW central inverter concept
  • Acceptance
    (September 30th, 2008)
    The acceptance, following the construction of a facility, involves various trials to verify the actual technical capability of the power plant in review on the basis of actual irradiation data. For qualitiy assurance strings and characteristic I-V module curves are being examined as well.
    Contract Design
    (April 24th, 2008)
    The technical contract design involves the enforcement revisable performance criteria and aligned acceptance criteria. Additional technical items are the definition of the optimising phase, performance guarantees and agreement of the operation and maintenance contract.
    Performance Data
    (April 16th, 2008)
    The performance data are defined by the output calculation and the technical assessment, defining the acceptance parameter in the contract. The most important criteria are annual output, performance ratio and earnings-/ irradiations conditions.
    Output calculation
    (August 14th, 2008)
    The output calucation evaluates on the one hand the irradiation and quantifies all power efficiencies. On the other hand losses caused during the production phase until the delivery to the network operation are deducted. Several scenarios are analysing the horizon and close-by shading for conducting a comprehensive output calculation.
    Technical due diligence
    (April 10th, 2008)
    The technical due diligence evaluates the technical documents and plans, controlls the laying and dimensioning, assesses the components, especially modules and inverter used, as well as the mounting system and it´s alignment. Additionally the tracking systems, the monitoring and the plant layouts are investigated.
