DMEGC Solar Energy Solar panels are getting more and more integrated in our environment and are indispensable as a key part of our green energy generators.

Fortunately, the decreasing prices for solar cells and panels, compared with the increasing cost of fossil fuels, are significantly reducing the payback time of solar systems.

By doing so we are able to monitor, optimize and guarantee the product quality throughout the complete process.

This is one of the key reasons DMEGC Solar Energy is dedicated to continuous product innovation and efficiency optimization.

3 DMEGC Solar Energy Solar panels are getting more and more integrated in our environment and are indispensable as a key part of our green energy generators. It s becoming more apparent for the general public, businesses, municipalities and governments that the transition to clean and sustainable energy sources is not just a desire but a necessity. Fortunately, the decreasing prices for solar cells and panels, compared with the increasing cost of fossil fuels, are significantly reducing the payback time of solar systems. Generation of electrical energy from sunlight requires solar cells that are mostly made from silicon. DMEGC Solar manufacturers these for our own solar modules as for other solar panel manufacturers. By doing so we are able to monitor, optimize and guarantee the product quality throughout the complete process. High product quality extends the panels life expectancy and longer life duration has a positive impact on the natural environment, as also for the user who invested in the panel. This is one of the key reasons DMEGC Solar Energy is dedicated to continuous product innovation and efficiency optimization. Not long ago we started the production of double glass panels which contributes positively to the panels life expectancy. And now we introduce a new technology, based on cutting the cells in two. (see page 19) Hengdian Group DMEGC Magnetics Co.,Ltd DMEGC Solar Energy was founded in 2009 as a new division from the decades old DMEGC. Over nineteen thousand employees are daily involved here in the production of magnetics that are used globally by manufacturers of domestic appliances, automotive and ICT hardware. The chances are high that you are using our magnets if you own a product of: Philips, Bosch, Samsung, LG, Sony, HP, Siemens, Renault or General Motors. Hengdian Group Hengdian Group DMEGC Magnetics Co.,Ltd in turn is a business unit of the larger Hengdian conglomerate, one of the largest private enterprises in China. In addition to the production of magnets and Solar Energy products, Hengdian Group is active in chemistry, electronics, pharmacy, tourism and entertainment. Hengdian Group DMEGC Magnetics Co., Ltd.

The SolarEdge power optimizers increase 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.

12 Storage 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 sleeping. 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 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 Magnetics 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 op PV-energy
