A report by Marc Eric Siewert
If you want to sail alone across the Atlantic with a boat that is only 6.50 m long, you need reliability (including the solar system), 100% confidence in yourself and your equipment.
This is what we, the Absolute Sailing Team, have been looking for since the start of our campaign in the Classemini on a Minitransat650 prototype. That means using high quality (solar) products and always keeping an eye on the cost/benefit factor (of the solar panels).
Originally, SOLARA solar panels of the type SM160M with the serial numbers 191737 and 218924 (from the production year 2005) and 45W each were mounted on our boat. These older generation solar panels have lower performance than panels from current production but still, work flawlessly.
After the first part of the journey from Les Sables d'Olonne to Santa Cruz de La Palma, we had to realise: Our energy management was not suitable to provide enough solar power for the situations of a solo transatlantic regatta. The solar panels were too small to cover the energy demand, especially for the autopilot. Therefore, we asked SOLARA for support with the latest solar technology.
At short notice, two more modern and significantly more powerful panels (solar modules) of the type M-Series S320P41 Marine, each with 80W, were sent to La Palma.
On the second stage from Santa Cruz de La Palma to Saint Francoise on Guadeloupe, the new panels (solar modules) always provided full lithium batteries during the day and only had to be supported by our backup energy source - a hydro generator - about every third night. Problem solved!!! Because without energy, there are no assistance and safety systems and above all no autopilot with solar power, and without these systems, a solo Atlantic crossing is impossible.
We are convinced by SOLARA's solar modules not only because of their high performance but also because of their high-quality, durable and very stable workmanship with an ultralow weight. In particular, the first-class surface coating of the solar cells and the aluminium carrier plate (Made in Germany!). These two aspects distinguish SOLARA solar panels from other panels on the market for recreational boating and offshore sailing.
A big thank you to SOLARA for this quick and uncomplicated support! Without your help, the Atlantic crossing would have been quite a bit darker.
Note: The previous 45W SOLARA modules will in future generate electricity on the roof of the Mercedes Sprinter of the Absolute Sailing Team!

Solar panels from SOLARA supply a measuring system in the North Sea for wind power plants.
The M-series, which has been tried and tested for over 20 years, is also used here.
The latest and most powerful version of the SOLARA M-series were used with the solar panel Art-No. S170M43.
"Yesterday our new solar panels arrived ☀️ We chose the Vision panels from SOLARA because they are particularly robust and therefore perfectly suited for the extreme conditions at sea. 🌊
We already had two of these panels for a year, now we are adding another two. In total we will have 640 watts of solar power and our Insieme will be a lot more self-sufficient. 💪💪"
We’re pleased to announce that SOLARA of Germany have become our latest confirmed Official Supplier for the HJ Sailing campaign.
“I’m really delighted to have the SOLARA team join our Golden Globe Race project, it’s another great step for our campaign and will provide us with some incredible Solar panels for Puffin’s new electrical system” reveals Ian.
For over 25 years SOLARA has been developing off-grid solar systems. SOLARA panels are used for various projects including the roofs of mobile and holiday homes, in parking ticket machines as well as racing and cruising yachts.
The stand-alone systems also help to power remote villages and houses in emerging or developing countries. The Golden Globe Race is the ultimate off-grid event, sailing non-stop around the world Ian will be alone at sea for up to 9 months, so the kit which SOLARA will be providing is going to be critical to keeping Ian’s communications and safety systems running during the race.
“We’ll be using SOLARA M Power Series flexible panels, with four fixed units on the deck and one mobile unit, which will give us up to 430W of power generation, at least during most sunny days of the race” Ian explains.

The distinctive feature is the solar roof with solar modules from SOLARA. Specifically made for the motor yacht Rapsody 29`. Aluminium rectangular profiles were mounted in a slightly curved shape in the longitudinal and transverse direction. Eight solar modules of the SOLARA Power M-series (type S505M34) were glued onto these with Sikaflex. The total output of the solar system from SOLARA is approx. 880Wp.
"The testing in summer 2020 on the Fulda with the commissioning of all components was extremely successful," says co-developer M. Meister.
The change from the combustion engine drives to electric drives, possibly with solar power, will become increasingly important for mobility in the future. The emission-free engine with no noise or exhaust fumes and with a solar power system will become increasingly important for boats as well.
The 4.5 t motor yacht with a diesel drive was retrofitted with an electric motor and a solar power system. The Li-ion battery (32 kWh) stores the solar power. The SOLARA solar system provides the necessary energy for the engine and other aggregates. Recharging can also be done in port or an emergency via an emergency generator on board.
The motor yacht Rapsody 29' is a joint project of the Fraunhofer Institute for Energy Economics and Energy System Technology Institute, Kassel, the Competence Centre for Decentralised Electrical Energy Supply Technology (KDEE) at the University of Kassel and the Volkswagenwerk Kassel, Baunatal, which supplied the electric drive.
Dear Mr Held!
Here is my promised contribution.
In search of suitable photos, our travel fever returned immediately. I will write you a few lines and attach some photos. Unfortunately, I hardly have any pictures that show off the solar module. It is so compact that it could always be placed technically well and not in the way. I often just put it on top of the sprayhood. I will be happy to provide photos of the new module in the coming season.
To get the highest possible yield with maximum flexibility in the future, there is already a desire for a Solara Power Mobil (S485M32). This could work wonderfully on the sprayhood in sailing mode and be ideally aligned to the sun at anchor. With an average daily yield of 485Wh, in future, it will be the shower that attracts us to the marina rather than the shore power.
For many years now, our Solara SM160M has accompanied us on our adventures on the Baltic Sea.
With our sailing boat KRABBE, we have sailed the island worlds of the "Danish South Sea" as well as the western and eastern archipelagos of Sweden, the Åland Islands and the Finnish archipelagos as far as Turku.
The degree of independence depends decisively on the energy management on board. For us, safe navigation, chart plotter, radio, lighting, but also the refrigeration of food and drinks should work best unnoticed but reliably. Only then can we relax.
The use of our solar panel allowed us to buffer the available battery capacity at anchorages for up to three days before we had to recharge either via the engine or a shore power connection.
After more than 20 years (manufactured in 1998!), our SOLARA solar panel has been through a lot. It has been crushed, rammed, sunk (and salvaged) and washed over by saltwater countless times. You can see that now. Despite all this, it still works reliably today - albeit with limited performance.
The old panel is far from being obsolete. During the unavoidable times in port, it will continue to be responsible for the maintenance and trickle charging of our battery bank. When travelling, however, we would like to be even more independent in the future. However, we could only realise a fixed installation with restrictions due to the required space. The panel would either be too exposed, in the way or too often shaded. Since we would like to have a comparably robust and reliable module again, we chose one of the SOLARA Power Mobil series. We can operate it on the sprayhood when sailing and align it ideally to the sun when at anchor.
Thanks to the mechanical wind steering system, our energy requirements on board for operating the refrigerator, chart plotter, radio, water pump, lighting, mobile phone and computer amount to a maximum of approx. 700 Wh/d. However, only very rarely are all consumers operated permanently and so we only average about 450 Wh daily. With an effective battery capacity of 1200 Wh (2 X 100Ah AGM) and an average yield of 485 Wh/d from the Power Mobil module, we will be able to cover our energy needs for at least a week, even on passages. At beautiful anchorages, we no longer have to worry about this.
An incredible challenge for the sailor who has to show all his strength against storms, drift ice, loneliness and frustration.
Only materials of absolutely mature developments and technologies are used. This guarantees the greatest possible security, quality, functionality and sustainability.
High-quality SOLARA solar modules and solar technology, from over 20 years of experience, make a significant contribution to achieving a new world record.
The ANT ARCTIC LAB project represents the first attempt to circumnavigate the earth non-stop, one-handed and without help from outside via both pole routes and through all five oceans of our planet with electricity from SOLARA solar panels!
This offshore record attempt will start on July 21, 2019 and will take skipper Norbert Sedlacek Koch over 34,000 nautical miles, thanks to solar technology, through the most dangerous waters on our planet for around 7 months, through ice, hurricane storms and monster lakes.
ANT ARCTIC LAB not only embodies a unique record attempt with the support of solar panels! The OPEN60AAL also embodies a completely new yacht construction concept, which can withstand the toughest loads, such as a collision with floating ice, through the use of pioneering volcanic fibers. In addition, all materials used are fully recyclable!
Follow the entire project at www.ant-arctic-lab.com.
For SOLARA managing director Frank Heise, not only the use of the in-house products was an argument for the cooperation, but also the recycling concept for the yacht as a whole. "A real argument in terms of sustainability today," says Frank Heise.
Solara solar panels have already won numerous awards on yachts and racing yachts. "It is always exciting to be part of such a challenge with solar technology from SOLARA. Again, it is demonstrated how our products assert themselves under these extreme conditions," continued Heise.
Sophisticated on-board electronics will also record the yield data of the solar system, so that we can later incorporate real practical data into our system planning.
"Of course we wish the skipper and the yacht all the best and a successful project."
The sailing boat OPEN60AAL is supplied with solar energy by eight solar panels from the SOLARA M-series and another two panels of the Power Mobil type.
A total of 644W of solar power will be installed. Especially in sea areas with lower sailing speeds, Skipper Sedlacek Koch expects its batteries to provide significant support from the solar panels.
SOLARA M (Marine)-series - Made in Germany. Very flat, walkable and semi-flexible solar modules. Absolutely sea and salt water resistant with high-performance solar cells.
"Since 12 years we have two SOLARA panels each 100W, sailing all around the world and are very satisfied.
Solar panels from SOLARA are perfect for our 10-year-long and continuing sailing trip. The main energy input clearly comes from the solar panels. We charge the 630Ah battery via an MPP regulator. The alternative energy gain is so good that, in addition to the usual on-board consumers, we also operate the 120l cooler box and every 4 days the watermaker, which produces 100l of drinking water over 2 hours, while charging the batteries with at least 38A.
Two monocrystalline SOLARA solar panels, each 100Wp, are swivel mounted on both sides of the railing and equipped with 2 length-adjustable supports for the footreel for alignment and stability. Aligning for best angle to the sun, so we imagined that at that time. Practice has shown however that we always let the panels look almost horizontally into the sky. Ideal for sailing, where at least on the barefoot route with the predominantly awful winds a wind generator on passages largely fails as an energy supplier.
I have destroyed one of the 100W panels due to carelessness. This is a good excuse to look for two new solar panels, with a little more power in order to meet the growing energy
Our favourite, again SOLARA in the version Power S-series with 120Wp with the smallest possible dimensions. The stable frame is ideal for assembly and 56cm width corresponds to common rail heights, so that even when folded down there is no problem with overhanging when walking alongside or "parking" in a marina box.

"I received an interesting article about solar technology in the marine sector, published in the "Professional BoatBuilder Maganzine". Very well written. The quality of SOLARA is of course also mentioned.
But what is more important is who wrote the article - Nigel Calder - a "US legend" in terms of sailing and technology on board. What Nigel says is correct, his voice has weight in the US Navy scene and certainly beyond.
I think the article is worth reading. The report describes very understandably different cell technologies, module structure and charge controller. In the end he comes to the conclusion that it makes no sense to buy cheap solar modules."

Summer means: Get out on the water and go sailing! - With SOLARA enjoy solar technical mobility at sea. The SOLARA Type M-Series is walkable, semi-flexible and specially designed for boats.
This is how a SOLARA - solar power plant for boats works:
For your sailboat you need as shown in the drawing:
In addition you need a battery and an inverter for 230V for grid connection, as long as they are not already on board. You can buy the components individually or as a SOLARA set.
First, determine all areas that are available on your boat for the installation of the
M-series. They should have a flat surface; it can be curved up to 3%. The M-series is available in different sizes, certainly also an appropriate size for your boat.
Should there be no space on deck; a standard solar module with frame and glass surface (e.g. the S-series) can be mounted onto a special support.
|Device||Power Rating||Operating time/day||consumption/day|
|Radio||15 watt||4 hours||60 Wh/d|
|Lamp||10 watt||5 hours||50 Wh/d|
For the daily requirement in our example, you need a solar panel with 27Wp (watt peak = maximum output) in the summer months.
If you have selected the right solar module, the specified nominal power (Wp) results in an approximate average daily yield (Wh/d) in summer. You simply compare this yield with your daily or weekly requirements. The result shows you how much of your daily electricity needs you can cover with your solar yield through the SOLARA-panels. Of course, the on-board battery must also be designed accordingly.
You can get a reliable guideline for your daily energy requirements if you use the individual consumption points on board, e.g. light, radio or refrigerator and multiply them by the respective operating time. The sum of these gives you your total daily requirement in watt hours per day.

ELEGANT AND ATTRACTIVE DESIGN
MAXIMUM PERFORMANCE WITH THE HIGHEST QUALITY
Solar panels need a good charge controller so that the battery is not damaged by being overcharged or creating a reverse current.
Just multiply the nominal output of the solar panel and select the appropriate charge controller with the corresponding module output.
We recommend the MORNINGSTAR-CONTROLLER with epoxy resin encapsulated printed circuit board. The controllers are microprocessor-controlled, have an automatic switch for 12 or 24 volts and can also charge gel batteries! With a temperature sensor, a deep discharge protection, a regulated characteristic with PWM charging, electronic fuses and 5 years warranty, it is ideal for yachts.
For extra yields of 15 to 20% per day, we recommend the MORNINGSTAR MPPT CONTROLLER. Optimal for the M-series with more than 36 solar cells in the module.
