Our logo represents our vision.

We see the energy source from which electrical power arises. With that power we supply the technology that we use in our daily lives.

The sun.

The source of all energy.

The light of the sun generates electrical energy in solar cells.

The warmth of the sun generates wind that drives wind turbines generating electrical energy.

With "NEW ENERGY." we imply the use of energy generated by the sun.

And with "TODAY" we indicate that we should use this energy NOW.

We are realists, though.

In the reality of today we are not yet able to cover our entire need of energy by renewable sources.

That's why we still need energy from fossile sources in the near future. But we have to do our best to do this as little as possible and as clean as possible. That is being visualized by this fire explosion.

This hybrid company car underlines this vision.


Electric when possible, diesel if necessary.

This is our main goal.

Electrical energy.

The sun in our logo visualizes generation of electric energy by the light of the sun and by the heat of the sun.

We believe in a world where electric energy plays a main role.

The power supply of the technology surrounding us, our transport and our heating.

This is the NEW ENERGY.

This new energy was generated at the sun 8 minutes and 20 seconds ago (the sunlight takes 500 seconds to reach the earth). We should use this 'fresh' energy as much as possible. We want to get rid of the "old energy"; that is, the use of fossile fuels. We want a transistion to a world where all electric energy is generated by the sun and by means of smart technology can be used by each and everyone. In the video below, Jermey Rifkin (economist en visionary) explains exactly what we mean:

Below we explain how we think we could achieve that.

Generating electricity

Generating electricity is the base.

We have to make sure that all electricity is being generated from renewable sources.

At this moment in time, the easiest ways of doing that are wind turbines and solar cells.

There still are many obstacles to overcome but let's suppose we can generate our entire energy need in this way.

Then, the next problem emerges immediatly: the storage of this energy. When it's a sunny and windy day we will have a huge surplus of energy and when it's a night without wind we will have no energy at all.

We will have to pay a lot of attention to the storage of energy in order to maintain a steady supply of energy:

The storage of electricity

The most obvious way of storage is the use of batteries.

Lithium batteries have a high density of energy per kilo, a long life span and a very high efficiency.

Batteries are being used locally; in cars, houses or boats. So, how can they be used as storage for the huge power that is being generated on a sunny and windy day?

By connecting all these batteries in an intelligent way. Every battery communicates with the energy suppliers. In that way, all these small cells become one big network with a large combined storage capacity.

That is our vision for the near future.

Storage of electricity 2.0

We believe that the ultimate solution for storage lies in the application of hydrogen technology.

By means of electrolysis we make hydrogen gas out of water with the surplus power from our wind and solar installations.

This hydrogen is being stored for later use.

If the demand for energy gets higher than the production, we generate extra electricity by means of fuel cells supplied by the stored hydrogen.

That is our vision for the future.


So far, so good. Like this we won't need oil or coal for our energy supply.

Now, we have to stop using natural gas as well.

By means of a heat pump we heat our houses with electricity.

Vision is nice but is this all possible in reality?

We think so.

But there is a lot to be done yet.

That's why we constantly think of new possibilities and development.

And we roll up our sleeves.

See for yourself:

An overview of our most recent projects

Energy system on a sailing vessel.

Energy Storage at sea.

Let's introduce myself: I'm Wim Winkelmolen, the initiator and owner of New Energy.Today. The sailing vessel "Dione IV" is an ongoing project. It is my own ship. I've build her myself and I live aboard for 15 years now. Here I develop, install and test energy systems.

It is an ideal situation for that: the ship is off-grid. That is a choice when we are in a harbour but at sea it is a must. During our long voyages at sea, the ship must be 100% self-sustaining. Energy for the navigation systems communication systems and auto pilot, but also for domestic consumption because we have a demand for comfort: boilers for hot water, cooler and freezer, washing machine and tumble dryer, coffeemachine, induction cooker, electric oven, electric bread maker, etc.

The electrical energy is being generated by solar cells on the top of the pilot house (900 Wp), 4 bifacial solar panels on railing (400Wp), windgenerator (600W) in the mizzen nmast, large 12v alternator (2kW) on the main engine and/or shore power (max 3600W).

By far, the most of electrical energy is generated by the solar cells on the roof of the pilot house (900 Wp) and the panels on the railing (400Wp) from Mito Solar.

The panels are custom made so that the entire available surface of the roof of the pilothouse is covered.

The panels on the railing are bifacicial and foldable. When they are at horizontal postion the rear side of the panels generate up to 30% extra energy from sunlight that reflects on the surface op the water.

At a sunny summerday we have a yield of approx. 8 kWh. From march to october (in the Netherlands) this is sufficient to cover our entire energy need.

The base for the energy system are 5 lithium batteries from MG Energy. 5x LFP 12v 210Ah is a total of 13,5 kWh energy storage.

The set has a weight of only 110kg and is positioned in a small couch in the saloon, seaworthy strapped to the pedestals of the casco.

We use about 3 kWh per day at an average stay on board so we can bridge 4 days when there is no charging on gray days without wind. If we cut back on energy (for instance, postpone the washing machine), we go down to 1 or 2 kWh/day and we can easily bridge more than a week.

Battery management system and DC distribution.

This has been positioned midship (where most cables come together) under a bed.

The charger/inverter is mounted under the same bed. The Multiplus 3000 from Victron supplies the 230v board systems. We have about 16 amps available, more than sufficient for all domestic appliances.

Monitoring and operation is being done by a Victron Cerbo (top display on the photo). Furtheron, a Raspberry Pi micro computer runs OpenHab software; there I program a custom interface to show the data wich I'm interested in. De RPi communicates via ethernet and WiFi with the boardcomputers and a tablet on the navigation counter (bottom display on the photo).

Battery-container for an Off-grid appartmentblock

Solar Energy storage.

With Off-grid factory we build a 40ft battery-container prefab in the Netherlands for Belnem house, Bonaire and install it on site at Bonaire.

This container with 500 kWh storage capacity and 135 kW inverter power supplies a luxury appartments building of 34 appartments. There is no grid connection available and the demand for energy is high. Because of the tropical temperatures there are about 100 airco's running in the appartments. All energy is generated by the solar panels on the roofs of the buildings.

The 64 lithium batteries of 7,2 kWh each and the battery management system are supplied by MG Energy.

The 9 charger/inverters of 15kW each and the 3 solar controllers of 12kW each are supplied by Victron and a Victron Cerbo controls and monitors the unit.

By means of a 4G router we are able to monitor and control the entire system from the Netherlands.

312 solar panels can generate 123 kW peak.

The larger part of this yield (about 100kW) is being handled by 2 large PV inverters from SMA and about 20 kW is being handled by 3 solar controllers from Victron.

On a January day we see a yield of about 107kW of solar power.

For backup, a 130 kW dieselgenerator is installed but we expect it to be barely nessecary.

We realize this project in close cooperation with the employer:

- The Off-Grid factory

and suppliers:

- MG Energy

- Victron Energy

Battery-containers for rental

Energy storage and peak-shaving.

Together with Off-grid factory we build battery-containers for Rent a battery.

These containers with a storage capacity of 100 kWh and 90 kW inverter power are rented on sites where extra energy is required temporarily. For instance, construction sites, events, holiday parks, etc.

Often as peak-shaving system. The container supplies power for high peaks in the consumption and thus a relatively small grid supply can be used.

But in off-grid situations, too, as energy storage system. For instance, in combination with a diesel generator; the generator only runs to charge the batteries. For example, on a construction site, a lot of power is needed during the day and the diesel generator only kick-in when batteries are low. And it runs at nominal power and during a relatively short time. At night, the batteries supply the power for the lights on site.

The battries and battery management are supplied by MG Energy.

The charger/inverters by Victron and a Victron Cerbo controls and monitors the unit.

The systeem is remote controlled by a 4G router.

On transport!

We do this project in close collaboration with the employer:

- The Off-Grid factory

Energy system on a sailing yacht

Energy Storage at sea.

On a catamaran we install an ESS (Energy Storage System).

The owner's wish is to be independent from shore power as much as possible and generate energy by solar power instead of a diesel generator.

There is a considerable power consumption on board because the couple live and work aboard and there are many electric appliances.

Under the bed in one of the aft cabins we install 2 lithium batteries from MG Energy with a total storage capacity of 14,4 kWh.

In the room in front of that, we install the BMS (Battery Management System) and the solar controller. In a cabinet we install a 5kW inverter/charger from Victron , wich supplies the entire 230v system of the ship.

At the aft of the ship we make a stainless steel frame wich carries 4 full size solar panels with a total power of 1100Wp. These are transparant glass-glass panels wich generate energy on the back side as well. Sunlight that reflects from the water surface generates extra power. The yield increases 10-20% by that.

A Victron Cerbo in the navigationcorner monitors and controls the entire system.

The result is that they barely need shore power any more and they can make long journeys at sea without power problems!

During a small evaluation, a while after we commisioned the system, the couple told us: "Our lives really have changed since we have this energy system. Previously, we were just sailing from one shore power outlet to another. Now, we don't have to worry about electricity at all; super relaxed!".

Off-grid system on the island Texel

Energy supply for a camera tower.

On a new sandbar on the outskirts of the island, scientists observe how nature (birds and vegetation) develops.

For that purpose, a camera tower has been placed. Of course, the camera's and the communication systems need electricity. But the nearest grid connection is many kilometers away from here. Therefore, we have build an ESS (Energy Storage System) wich supplies solar energy to the tower.

4 full size solar panels supply a lithium battery via 2 seperate solar controllers .

A Victron Cerbo controls and monitors the unit.

The system is remotely controlled and monitored by means of a 4G router.

We do this project in close collaboration with the employer:

- The Off-Grid factory

and suppliers:

- Victron Energy

Self consumption system / backup system

Energy-security and consuming self generated solar energy.

At a small farmhouse we install an ESS (Energy Storage System) with a power of 5 kW.

In the cabinet are 2 lithium batteries from MG Energy with a total storage capacity of 15 kWh. The solar controller, inverter and monitoring are from Victron Energy.

The system is remotely monitored and controlled by an internetconnection.

On the roof we mount 9 solar panels.

The energy that these panels generate is being self-consumed here. So there is no feed back into the grid.

In case of a grid failure, this installation takes over the electricity supply from the most important parts of the house.

We do this project in close collaboration with the employer:

- The Off-Grid factory

and suppliers:

- MG Energy

Off grid system

Energy supply on a remote location.

Military exercise terrain and shooting range airforce at "De Vliehors". This is de most westerly area (inhabited) of the island 'Vlieland', north of The Netherlands. It is an extremely remote and hostile location, dozens of kilometers away from the nearest grid access.

Here, we install an energy storage system for solar power at a 14m high camera tower for The Off grid Factory.

On top of the tower, an extremely advanced camera is mounted, which observes the hits from the bombs and canons from exercises of the jet fighters day and night. It sends the images via a radio link to the command center.

12 full size solar panels must supply the energy for the camera, day and night.

We use tansparant glass-glass panels. These panels generate energy at the rear side as well, resulting in much more yield: we see 50-60% above the specified Wp of the panels.

We have installed the entire system in a watertight stainless steel cabinet because of the extremely hostile environment: storm, sand, salt water, heat, frost, etcetera. There is no shelter here.

In the cabinet, 2 lithium bateries from MG Energy are mounted, with a total storage capacity of 15 kWh. The 2 large solar controllers, inverter and monitoring device are from Victron Energy.

The system is being monitored by a 4G data connection. If nessecary, we can operate and control the system remotely, too.

As a backup, there is a fuel cell (not on the photo). This fuel cell works on ethanol and kicks in at a too low state of charge of the batteries.

Large Energy Storage installation.

Large Energy Storage installation.

On the roofs of a large house and adjacent shed the owner has installed a large number of solar panels; about 30 kWp in total. His wish is to be fully self-supporting in case the grid fails. Not only where it concerns the direct electric power supply but also his heating (heat pump) and drinking water (well), which also require electric power.

At the attic of the shed we install 3x Victron Quattro charger/inverter with a power of 3x 10kVA at 3 fase.

2x SMA Sunny Boy in the shed and 2x SMA Sunny Boy in the house supply solar energy on AC to the system.

The storag/buffer capacity is 60kWh, supplied by 16x BYD B-Box battery

The installation programmed, commissioned and tested.

When we switch off the grid in the house distribution cabinet, the system takes over seamlessly; we can't even notice the lights flicker.

The Victron Cerbo monitors and controls the entire system.

Early spring sunshine generates already 11kW.

We do this project in close collaboration with employers and supplieres:

- Off-Grid factory (employer)

- Victron Energy

Upgrade energy supply Survey vessel.

Upgrade energy supply Survey vessel.

This ship carries out surveys of the sea bed. The dieselgenerator runs continually to supply power to the survey equipment and many computers. But also, the main engines run all day. So the idea is to supply the 230v board net with an inverter supplied by a battery bank which is charged by the 24v DC from both main engines alternators. Then, the dieselgenerator would be no longer nessecary and that saves emission and costs....

We install a Victron Quattro chrger/inverter with a power of 8kVA, supplied by 4x 220Ah GEL batteries which are charged by the alternators on the main engines. 8 kVA is sufficient for all survey equipment, computers and domestic equipment.

We refit the entire primary DC en AC distribution.

The Victron Cerbo monitors and controls the entire system.

The result: 2 months later, during a visit on board, the skipper tells us he doesn't use the dieselgenerator at all! Previously, the genset ran 24/7...

We do this project in close collaboration with employers and supplieres:

- Off-Grid factory (employer)

- Victron Energy

Enlargement off-grid installation.

In the Off-grid system that was installed by us last year in a house we extend the battery power from 30 kWh to 45 kWh.

Because in winter during long periodes without sunshine the total battery capacity sometimes appeared insufficient we install 2 extra 24v 280Ah batteries.

This is one of many advantages of the Lithium batterijen from MG: within a few years we can add extra batteries to the existing set witout a problem. That means that customers can start with a small set, determine the performance during a couple of seasons and extend the set if nessecary.

We do this in close collaboration with the client and suppliers:

- Top Systems (supply materials)

- MG Energy Systems (thechnical support)

Enlargement large Energy Storage installation.

In our recently completed ESS (Energy Storage System) in a large house, we double the inverter power from 30 kW to 60 kW (2x 3 fase 10 kW).

Because the house sometimes uses more energy than the grid can supply, "peak shaving" is very important; peaks that exceed the current that the main fuses can handle are being absorbed by power coming from the batteries.

We do this in close collaboration with the owners and suppliers:

- Victron Energy (all electronics)

- MG Energy Systems (Lithium batteries and battery management)

Off-grid installation "Curringherveld".

In the nature reserve "Curringherveld" nearby "Kornhorn" (state Groningen, the Netherlands), the beautiful wooden shed "Curringherschuur" is build by volunteers.

Because of the remote location of the shed there is no grid connection. Electricity is needed however, because groups of children from schools use the shed for nature education and all kinds of meetings are organized, such as presentations, business meetings, weddings, etc. So, the required electricity is being generated by solar panels.

These solar panels are transparant, so that light (and warmth in winter) can enter the building.

The electricity generated by the solar panels is used for fridge, cooker, coffee machine, lights, waterpump, charging of battery powered gardening tools, etc.

For storage of the solar energy, New Energy.Today installs an een E-rack from MG Energy Systems with a capacity of 15 kWh.

A 10 kW Victron Quattro transfers the energy from the batteries to 230v AC for the building.

A Victron Color Control controls and monitors the installation. A router with a 4G connection offers the possibility to monitor and control the system online.

We do this project in close collaboration with the employer and suppliers:

- Stichting Curringherveld (employer)

- Top Systems BV (supply of materials)

- Victron Energy (all electronics)

- MG Energy Systems (E-rack Lithium batteries)

Energy Storage system on a boat.

At the stern of a catamaran (the Lagoon 445 "Horizon"), the owners have installed 5 large solar panels with a total peak power of 1700 W. Special about these panels is that they are transparant (solar cells on clear glass). Because of this, they generate energy also on the bottom side: sunlight reflecting from the surface of the water generetes enrgy on the bottom side. This increases the yield by 20%.

To store this energy for self consumption we install an energy storage system with a capacity of 7,5 kWh and an inverter power of 3 kW at 230 volts in the boat. We choose to do this with minimal modifications to the existing electrical on the boat: the inverter actually replaces the shore power input.

The owners Gilles and Laura sail for 3 months in the summer of 2020 in Denmark and they are fully self-supporting with this system. There is even an energy surplus, even if they use about 10 kWh per day (an average house uses about 8 kwh per day).

We do this in close collaboration with the owners and suppliers:

- Victron Energy (all electronics)

- MG Energy Systems (Lithium batteries and battery management)

Slideshow of the various fases of the intallation.

The solar yield is huge. Everyday at around noon we see a yield of more than 1 kW and even in august we see peak power (1700 W) sometimes. In july, they even reached 1900 W!

Test site for battery systems from the real estate department of the Dutch government.

The Dutch government wants to do research for the best system to store solar energy from governement buildings for self consumption.

That's why a test room for 5 battery systems is created at the former marine airport near Leiden. NewEnergy.Today installs all Victron equipment and does the commissioning of these systems.

We do this in close collaboration with the employer and suppliers:

Large Energy Storage installation.

At both sides of the roof of a large house, the owner has placed 160 big solar panels. A total peak power of over 50 kW.

To self-consume this enrgy as much as possible, we install an energy storage system with a capacity of 120 kWh and an inverter power of 30 kW (3x 10 kW 3-fase) in the technical room of the house.

We do this in close collaboration with the owners and suppliers:

- Victron Energy (all electronics)

- MG Energy Systems (Lithium batteries and battery management)

- Installatiebedrijf Hoekstra (Connection to the house and the grid)

Slideshow of the various fases of the installation.

After a brief period of adjusting we reach a setting where the consumption comes either directly from the solar panels, either from the batteries (when there is no sunshine). The surplus of energy is being fed back to the grid.

Large Off-grid installation.

On the roof of a big shed next to a house in the country, the owner placed 77 big (330Wp) solar panels. A total of 25 kW peak power. The owner wants to be fully off-grid and has no grid connection.

We take care of the enigineering and the installing of all technology in the shed. The energy supply of the house.

For NewEnergy.Today this project runs from the calculations and design of the electrical system in august 2019 to the commisioning in december 2019.

Slideshow of the various stages of the installation.

In the early morning of the day of the commisioning there is a faint december sun.

At that time, the batteries al being charged with over 3 kW already. This is promising; it is important that there is enough energy in the months december and january for the (-sparingly-) household. The rest of the year there will be no problem; then we'll have a huge energy surplus. The next step in this project is to decide how we will store that! Maybe producing Hydrogen! We keep you informed...
