Solar energy for boats and yachts

Enjoy your free time with the greatest possible freedom - with our off-grid solar systems for boats. 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).

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:

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.

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.
