The non-slip, fully accessible and resistant SOLARA modules guarantee a reliable power supply in the sea, even without access to a power supply. Our solar panels guarantee what you need for an active rest: the feeling of freedom, independence and security.

Electricity without grid connection thanks to SOLARA

solar energy for boats and yachts - Solara

Anyone travelling on his sailboat or his boat is often without access to on-shore supply to cover its electricity for days. Exactly for these carefree leisure days at sea or in silent, in bays distant from civilization, we have developed our SOLARA solar modules Type M-series for sailboats and boats.

 

For all SOLARA photovoltaic systems there are suitable charge controller and display. Convince yourself of the benefits of flat solar modules of Marine (M) series. They are designed for navigation, are extremely flat, accessible and flexible.


With our SOLARA-modules for your sailboats and boats you get

  • High service quality
  • Best brand quality
  • Excellent workmanship
  • High current income through additional individual cells and the best low light
    performance (even in diffuse light)
  •  long time warranty
  • Additional equipment in high quality from premium brands

Important information about modules, charge controllers, mounting systems, inverters or complete systems can be found on this website (see at products).



With SOLARA sailing around the world, a wonderful experience.

Letter from Andreas Haensch and Andrea Fuchs, S / V AKKA, Hallberg Rassy 42E, currently Trinidad, W.I.

For 12 years we have two SOLARA panels each 100W, sailing in the wide world and are very satisfied.

 

Solar panels from SOLARA are perfect for our 10-year-long and lasting sailing trip. The main energy input is clearly from the solar panels. We charge the 630Ah battery via an MPP regulator. The alternative energy gain is so good that we also operate a 120l cool box next to the usual on-board uses and the water maker every 4 days, which produces 100 liters of drinking water over 2 hours, while at the same time charging the batteries with 38A.

 

Two monocrystalline Solara solar modules 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. The practice has shown, however, that the panels always look almost horizontally in the sky. Ideal for sailing, where at least on the barefoot route with the predominantly awful winds a wind generator on passages as an energy supplier largely fails.

Now I destroyed one of the 100W panels by a carelessness. This is a good pretext to look for two new solar panels, with a little more power to look out for the growing energy requirements.

Our favourite, again SOLARA in the version Power S series with 120Wp with the smallest possible dimensions. The sturdy frame is ideal for assembly and 56cm width corresponds to common rail heights, so that there is no problem with docking when folded down.

Best regards

This is how a solar power plant works

Summer means: Get out on the water! - With SOLARA enjoy solar technical mobility at sea. The SOLARA Type M-Series is specially designed for boats.

 

This is how a SOLARA - solar power plant for boats works:

Solar plant for yachts - SOLARA

For your sailboat you need as shown in the drawing:

  1. A SOLARA-module (e.g. M(Marine)-Series) for energy production
  2. Optionally a special adhesive set for bonding the solar modules securely with the deck
  3. A cable tunnel (Item.-No. DD1, in white) for the cables to go through your roof without leaking
  4. A charge controller with LED-panel for monitoring the battery and charge and also for battery overload and back going electricity
  5. A UV-resistant cable to connect the solar panel with the charge controller and the battery

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.



SOLARA PowerMobil Series - Robust and reliable with 102Wp

ELEGANT AND ATTRACTIVE DESIGN

  • Thanks to innovative, fully encapsulated materials, it can be used flexibly
  • Pull-on or hook-and-loop fastener connections can be retrofitted or fixation loops can be set
  • Space-saving thanks to collapsible module surface
  • Effective battery charging even in the vehicle in the shade
  • No fixed mounting required


MAXIMUM PERFORMANCE WITH THE HIGHEST QUALITY

  • Extremely high efficiency due to the use of monocrystalline cells with reverse contact with over   22% efficiency
  • Yield is high in all seasons, even in diffuse light
  • UV-stable solar connection cable as well as cable output

In three steps to your solar power plant with SOLARA-modules type M-series for your boat

Step 1: surface analysis

SOLARA solar energy plants

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 in the rear.



Step 2: get your power usage per day

Once you have selected the appropriate solar module, an approximate average daily yield (Wh/d) results from the rated output (Wp) in the summer. This yield you align your daily or weekly requirements. The result shows you how much of your daily electricity needs can you meet with the SOLARA-module. Of course, the onboard battery must be designed accordingly.

 

You get a reliable guideline for your daily usage: list the individual components of your caravan – for example: light, radio, freezer – like the chart down below. Afterwards you multiply the rating with the usage time. The sum of all your devices is the daily power usage.

Device Power Rating Operating time / day consumption / day
Radio 15 Watt 4 hours 60 Wh/d
Lamp 10 Watt 5 hours 50 Wh/d

The daily requirement in our example, you need during the summer months a solar module with 27 Wp (watt peak = maximum power).



Step 3: Choosing the right charge controller for your solar module:

Solar modules need a good charge controller so that the battery will not be damaged by being overcharged or a backflow occurs.

Just multiply the nominal output of the solar module and select the matching charge regulator 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! Ideal with a temperature sensor, a deep discharge safety, a controlled characteristic with PWM charging, electronic fuses and 5 years warranty for boats

 

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.


We also recommend a SOLAR LED indicator for your battery status.
