MG will take on the challenge to drive fossil free – indefinitely

With 360 brand new solar panels on the roof to power our entire battery factory, we’re eager to put them to the ultimate test. MG will join the Frisian Elfwegentocht: a province wide challenge to drive entirely fossil free for two consecutive weeks. However, we’ll try it one step further – aiming for indefinitely.

The Elfwegentocht

The Elfwegentocht is an initiative from local students dreaming of a sustainable Friesland and eager to prove it’s already possible to travel fossil free. That’s why they’ve set up a challenge for everyone to move with sustainable means of transport within the borders of the province, from 1 to 14 July 2018.

Meeting new demands

Be it on foot, (e-)bikes, electric cars, green gas buses or even trains on sustainable power, it’s a 14-day-long demonstration to drive without a drop of petrol. And quite an endeavour, as it will pose a challenge for the participants and infrastructure alike to meet these new demands.

Major contribution

We’re very much in favour of this plan and trying to participate in any way we can. Our brand new 360 solar panels on the roof will make a major contribution to power our five electric cars and one electric bike. In addition our other cars will be provided with blue diesel.

Indefinitely

These adjustment will enable us to meet our target for the Elfwegentocht. However, this is only the beginning, since we feel a fortnight is not nearly enough. We haven’t set an end date, but instead will try to continue driving fossil free for as long as we can – indefinitely. So here’s a challenge: are you ready to join us?

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.

Solar airplanes: future or reality?

Are solar airplanes reality?

Flying a commercial passenger airplane from point A to B takes a huge amount of energy and power. If these demands were translated to a sustainable solution based on current technology by replacing kerosene with batteries, the weight would be much higher and more surface would be needed (or more efficient solar cells) to yield sufficient energy.

So it may not be possible for commercial passenger flights yet, but there are several initiatives to prove that solar powered electric airplanes are indeed the future.

One example is the famous SolarImpulse initiative that aims to fly around world on solar energy. The Solar Stratos project takes it even one step further, demonstrating the potential use of renewable energy by taking on the challenge of flying a solar powered electric airplane all the way to the stratosphere (altitude of 20 km).

Apart from these special initiatives, there are a number of commercial manned and unmanned (drone) airplane projects with different goals. Google’s solar powered drone, for example, has the goal to spread internet all over the world, especially to remote areas. These so called atmospheric satellites also fly at an altitude of 20 km.

Solar energy

One thing alle these projects have in common is the need for solar energy to power their flight. This is where MG comes into play. The energy generated from a solar panel is only a small percentage of the available solar power, typically between 20% and 25%. On earth the average irradiation is around 1000 W/m2.

This means if a solar panel has an efficiency of 25% the generate solar power from the panel is 250 W per square meter. Because of the small amount of energy converted by the solar panel, it is important to convert this energy with the highest possible efficiency in order to use it for propulsion or charging batteries.

The Maximum Power Point Tracker (MPPT)

Converting solar power to charge batteries with the highest efficiency is one thing, but solar panels are not an ideal source of energy. Each solar panel has a so called IV-curve, demonstrating the relationship between current and voltage. Figure 1 shows a particular example.

The key to getting the maximum amount of energy from a solar panel is to ‘search’ for the Maximum Power Point, which is called ‘tracking’. A DC/DC convertor with a Tracking function is required to convert the energy from the solar panel to charge the battery or use it for propulsion. This type of converters is called Maximum Power Point Tracker (MPPT).

Figure 1

There are basically two types of MPPT’s: Boost (from a lower solar voltage to a higher battery voltage) and Buck (from a higher solar voltage to a lower battery voltage). The type of converter we developed is a Boost converter. The MG Solar MPPT is a highly efficient MPPT with a ultrafast tracking algorithm.

 

MG’s history of development

The development of our MPPT began when we started building a solar powered boat, to participates in several solar challenges all over the world. After successful usage in this project, it we further optimized the efficiency and Tracking algorithm.

Several other race participants noticed the existence of our converter, for example the TU Delft solar team, participating in the World solar challenge in Australia with their Nuna car

s. They tested their existing best MPPT and compared it to our newly developed one.

Upon concluding MG’s new MPPT had a higher efficiency, they began to use it in their solar cars. After their successful win, more and more teams took an interest.

Now over … teams use our Solar MPPT. Every team has their own configuration and the Solar MPPT’s are tailored to their needs.

It’s possible to customize on voltage range, maximum current, connections and CAN-Bus communication.

The use of MG Solar MPPT in Solar Airplanes
The use of our MG Solar MPPT for racing purposes was also noticed by several solar airplane initiatives. One of the companies, Elektra Solar, implemented it in their one seater solar airplane, to face ‘the challenge of stratospheric manned and unmanned flight with solar-powered and emission-free aircraft”.

MG’s Solar MPPT solution ensures the maximum energy yield from the solar panels while keeping the added weight as low as possible, as you can see on our product page.
