The bonus of Bi-facial Specials DMEGC Solar actively supports innovative projects. For instance with specially produced frameless modules. The energyboost of Bi-facial modules is, dependant upon the set up, 5-30 %! On earth, sun rays mostly come from above, under an angle. Unless you are standing on the equator, at noon. A Bi-facial module can be used in: The rays are often reflected by clouds, water surfaces or buildings. These indirect rays can still contain energy. They can reach solar panels from the sides, or from the back. Flat roof installations, on a light colored or white roof, or covered with reflective foil Floating installations. The water will reflect much of the sun rays to the back. Roof of a public transport terminal, Doetinchem When using Bi-facial solar cells energy can be generated from rays reaching its back side. But the backside needs to be visible for the rays. This is made possible with transparent foil, or with a second glass plate. As can be read on page 10, this also extends the life duration of the module. Vertical set-ups, for instance in sound barriers. When these are placed along roads they can of course not always have the best angle for the reception of solar rays. The effects of this can be minimized or even turned around by installing Bi-facial modules. Soundbarrier Studyproject Prêt-à-Loger i.c.w. TU Delft/Bouwkunde The efficiency improvement depends strongly on the positioning of the module and the color and structure of the reflective surfaces under or near it. If these surfaces are painted white or covered with reflective foil, the output will be further optimized. 16 17
Close cooperation in The Netherlands Goeree-Overflakkee (an island in the south west of The Netherlands) is on track to reach its target to be energy neutral in 2020. As part of this, Sunstroom Engineering realizes the solar parks Melissant en Ooltgensplaat in close cooperation with DMEGC Solar Nederland. 168.000 DMEGC solar modules will be installed in total, with a capacity of 47 mega watt peak. Solar park Melissant surface: 180.800 m 2 capacity: 10 MW Optimize your system DMEGC Solar modules can be embedded with an SolarEdge power optimizer instead of the standard solar junction box. The DC/DC converter increases energy output from PV systems by constantly tracking the maximum power point (MPPT) of each module individually. Furthermore, the power optimizers monitor the performance of each module and communicate performance data to the SolarEdge monitoring portal for enhanced, cost-effective module-level maintenance. Each power optimizer is equipped with the unique SafeDC feature which automatically shuts down modules DC voltage whenever the inverter or grid power is shut down. The MPPT per module allows for flexible installation design with multiple orientations, tilts and module types in the same string. When working with SolarEdge Inverters, SolarEdge power optimizers automatically maintain a fixed string voltage, allowing installers even greater flexibility with longer strings and strings of different lengths in order to design optimal PV systems. Current and warm water from one module By integrating a thermal collector in a DMEGC Solar PV module, Alius Energy has developed an unique product. In situations where one wants to generate electricity as well as thermal energy with solar power, the VolThera PVT system can be a good choice. The VolThera modules can not only be the solution in situations with limited physical space, but also when a uniform look is desired. Standardly equipped with an SolarEdge power optimizer, these modules can be combined with standard PV-modules within one installation. DMEGC Solar has of course tested the VolThera modules extensively, to determine if the performance of the system and the quality of the panel were influenced by the integration with the thermal system. That turned out not to be the case, so the warranty on the PV-part remains the same. 18 19

Storage Certified by Solarif Solarif is a worldwide independent insurance advisor protecting PV assets, a risk assessor of solar panels and inverters for manufacturers willing to become Solarif-certified and a professional matching service for PV project buyers and sellers. Solarif sets requirements which the manufacturer has to meet when he wishes to become Solarif-certified. In order to be able to meet the requirements, the manufacturer has to allow Solarif to assess their production processes and financial situation. If necessary, current processes and procedures will have to be adapted. If the manufacturer meets the requirements, Solarif will place the approved panels or inverters on the list of Solarif-certified products. After certification a yearly audit takes place to verify whether the products and financial situation continue to meet the requirements. Check out the overview of the Solarif certified manufacturers: https://www.solarif.com/partners/manufacturers Storage of (solar) energy Production of photovoltaic energy is quite common these days. All around us we see solar panels on roofs of houses and company s and in large scale projects. It is evident that solar energy as percentage of the total energy production is increasing. But the sun doesn t shine always. Clouds can obstruct the solar rays, and at night, of course, the sun doesn t shine at all. We live in a 24 hour economy nowadays, using electrical equipment all the time, even while we sleep. So our energy consumption is not in sync with the times when solar energy is produced. Energy storage is the solution for this. And with the increasing production volume of PV energy there is also a growing need for storage. DMEGC Hengdian Group DMEGC Magnetics Co.,Ltd DMEGC Lithium Battery Division Electrical energy can be stored in batteries, and for long series of charging- and discharging cycles lithium-ion batteries are the most suitable. For this reason DMEGC has set up a new production facility for li-ion battery cells Battery cells are the building stones of battery packs. Mostly the cells are invisible to the user. There are three production lines: one for cells used in electrical power tools and rechargeable domestic appliances; one for electrical mobility; and one for the storage of PV-energy.
