MG’s battery factory runs on solar energy

Here, at MG, we’re passionate about energy and making the transition to an economy run on fossil-free fuels. As we strive to be forerunners in the field of storage solutions, we put our money where our mouth is. Last weekend we’ve installed 360 solar panels on the roof to power our entire battery factory.

Grid stability

Due to the growing number of solar parks and wind turbines on one hand, and a surge in electric transportation on the other, the grid is increasingly taxed with extremes in supply and demand. One moment there’s a steady surplus, the next a sudden shortage. These fluctuations will only intensify, resulting in more frequent power cuts.

Local storage

However, these peaks can be easily accommodated by local power storage. At MG Energy Systems we’re anticipating the future by developing energy storage solutions based on Lithium-Ion batteries, complemented with built in management systems to charge and discharge with extreme efficiency. Powerful enough to run our factory.

Solar panels

We chose solar panels with a very high efficiency, using the latest MWT technology (Metal Wrap Through) co-developed by

Eurotron. This technology reduces the risk of microcracks by not soldering the solar cells but gluing them, thereby ensuing a higher yield over the lifetime, compared to traditional solar panels.

Energy yield

The annual output of this installation accounts for approximately 100,000 kWh of energy. The performance is accurately tracked by means of absolute irradiation measurement with a pyranometer and the energy yield of the panels. All data are collected in the cloud and can be accessed via the MG Energy Portal, a modular web platform developed by us to monitor energy systems.

Carbon footprint

The power generated will primarily be used for all assembly and development processes in our battery factory. In addition, all five of our electric cars are being charged with solar energy to make sure we travel fossil free. Due to these measures the carbon footprint of our company and our products is relatively small.

Energy storage

The energy storage system, installed in combination with the solar panels, can be used for various applications, such as peak-shaving, grid frequency stabilisation (FCR), backup and self-consumption, each with its own business case. As most of these meet our own needs and demands, it’s a perfect impetus for further exploration.

MG Energy LAB

The solar panels and storage installation are part of the Energy LAB that was set up at MG Energy Systems, as a playground for innovation and development. For example, solar panels, storage systems and charging infrastructure for electric cars are combined, developed and tested. We consider the Energy LAB as a platform to develop energy systems of the future.

Ultimate test

Always eager to put our systems to the test, we’re excited to announce we’ve found the perfect challenge.
