    pH value and conductivity measurement for power plants

    Growing populations – about 80 million every year – and industrializing countries create huge needs for electrical energy. According to the International Energy Agency (IEA) the global energy demand will increase by about 65% by 2035. A major fraction of the required energy will continue to be provided by thermal – mainly fossil fuel-fired and nuclear – power plants. "Renewable" energy sources such as photovoltaics (PV) will be another backbone of our energy supply. Putting renewable energy on the grid requires powerful energy storage and conversion devices, such as supercapacitors, batteries, or fuel cells.

    Instruments and analyzers for PV modules performance assesment

    Usually, the performance of a PV module is measured at the factory under the so-called Standard Test Conditions (STC), described in IEC 60904. This is a convenient test method that can be integrated in routine production procedures. However, the indoor measurement of the STC PV performance reveals the power production of the module at only one particular measurement condition.

    Instruments and analyzers for DNI measurements at CPV sites

    Concentrating Photovoltaics (CPV) is driven by only direct solar radiation. To quantify the energy efficiency of a CPV system the total DNI and direct spectral solar irradiance, called spectral DNI, can be measured. Solar sensors are crucial during the phase of development and operation. Even at high sunny places, the composition and variability of the atmosphere strongly affects the solar spectral distribution and will impact on the energy yield and the decision on which cell type to use. The pyrheliometer in combination with the spectral radiometer for DNI measurements accurately pinpoint the solar prospect for certain sites, the spectral impact on the performance and efficiency of the module.

    Chemical Analyzing in Photovoltaics for the Solar Power Industry

    In the earlier days, the chemistry involved in solar cell manufacturing was relatively simple, using commodity chemicals. With cell efficiencies continuously on the rise and new cell concepts slowly being introduced with increased speed of processing, precise chemical concentration control is becoming crucial to obtain consistency and more cost-effective manufacturing of solar panels. This is possible by monitoring on-line the etching bath composition, a small but genuine step forward in your competitive advantage.

  • Evaporation technology for photovoltaic & microelectronics industries

    The manufacturing process of the cells that make up the photovoltaic systems and the printed circuits require water in quantity and high quality. This water has to be managed wisely so as not to affect the productivity and the expenses of the plant.

  • Metrology for the photovoltaics industry

    Quality control to maximize efficiency is critical in the competitive photovoltaic industry. For some time solar texture has been thought to qualitatively affect solar cell efficiency. However, through large-area, 3D measurements and areal feature parameters, quantitative correlation of texture to efficiency has only recently been obtained. We now know that ISO 3D surface parameters linearly correlate with solar cell efficiency.

  • TESTS ON THE FIELD FOR PV PLANTS

    There is no legislation to control of the proper functioning of pyranometers used to measure solar radiation installed in the PV field. The control can be effectively carried out with portable instruments suitable to avoid uninstalling pyranometers set in areas normally inaccessible as placed at the side of panels. A quick test on the field assesses whether a good maintenance is sufficient to obtain a reliable measurement of the solar radiation or if it is necessary to send radiation sensors to the manufacturer for a control. In order to make a test on the field and verify the proper operation of a photovoltaic system, Delta Ohm provides a set of tools that allow an easy and flexible use.

  • Supervision of Photovoltaic Power Plants in Japan

    The team of K&S technical experts perform independent technical inspections of the photovoltaic system and clarifies technical issues. The advisory service begins even before the actual construction of the photovoltaic power plant - in the design and contract review. It is ensured that all the requirements of the building permit of the relevant Japanese authorities are fulfilled and the contract is aligned with the system. Based on the continuous construction and factory acceptance tests of components, possible quality defects from the start can be reduced to an absolute minimum. With the local networks of the Japanese technology institutions such as New Energy and Industrial Technology Development Organization (NEDO), Japan Electrical Safety & Environment Technology Laboratories (JET), Japan Photovoltaic Energy Association (JPEA) and other leading technology institutions, K&S combines a comprehensive local technical advisory service in Japan.

  • Energy Storage

    The K&S Engineering company as a technology 'know-how' supplier has prepared algorithms for optimizing energy storage systems and developed a new simulation tool for it. Using this special simulation software, not only the major yield forecasts for the investors are done in detail, but it is also possible for the applied control algorithms to perform optimizations. With this, K&S offers a consultancy service combining photovoltaic-energy-storage-system design and the perfectly match of the upcoming control algorithms to be applied. As a supplementary service for investors and banks, K&S performs a technology and supplier evaluation in an technical risk assessment regarding the project. A first project with >30 MWp installed capacity in Japan with special requirements of the energy supplier and a nearly 20 MW battery power has already successfully been modeled by the K&S experts.
