Solar power for campers and boats

This is how a solar power plant works in campers and caravans

Are you interested in the idea of covering the power needs of your motorhome or camper in the future with a solar power system? Then you have come to the right place. With our simple guide you will get step by step to the optimal solar power system, which is ideally adjusted to your individual power consumption.

For your RV or caravan you need as shown in the drawing bellow:

Solar plant by SOLARA
  1. SOLARAMODUL (e.g. S-Series) for power generation
  2. ABS-holding spoiler in an appealing white to securely mount the solar panel
  3. Specialized adhesive set for securely gluing the ABS-holding spoilers to to your vehicle roof
  4. Cable tunnel (Art.-No. DD1, in white) for waterproof and permanent routing of the cable from the solar panel to the charge controller
  5. Charge controller with LED-display for monitoring the battery and charge and also to protect the battery against overcharging and reverse currents
  6. UV-resistant cable to connect the solar panel with the charge controller and the battery

In addition you need a battery and possibly an inverter for 230V for household current, as long as they are not already on board. You can buy the components individually or as a SOLARA set.


In two steps to your complete solar power system for your camper

Step 1: Determination of your daily power requirement

To find out how big your solar system should be for your motorhome, camper, van, caravan etc., you have to take a closer look at your consumers and their energy requirements. This depends on the number of devices, the power consumption of the device and the daily switch-on time. In addition, the number of people and the period of use within a year influence the energy consumption.

Sum up the energy consumption of your camper etc. according to the table below - the result is your daily power requirement (Wh/d, wtt hours per day). Depending on your consumption behaviour and the time of use within a year, this consumption should be more or less covered by the solar system.

The outcome in this example: with a power consumption of 680Wh/d you would require in the summer time a solar panel of 160Wp (watt peak = maximum power) we recommend you a SOLARA complete system with SOLARA modules of the highest quality including optimized for that a quality-charge controller and a mounting system from our own research with TÜV-tested security.

Here you see a SOLARA complete set for the leisure usages. We have optimized it for different energy needs. Therefore, they are available in different designs and performance levels. Please consider when choosing the set or module for your RV, when and how often you are on the track. When in doubt, the best way is to go with the next higher performance class than the estimated or an additional module. This gives you more energy security, and a faster charge.

Step 2: Selection of the SOLARA complete set for your individual daily power requirements

Based on the calculated electricity requirement, select one of the following sets.

All SOLARA complete sets consist of high-quality SOLARA solar modules - Made in Germany, matching charge controllers, holding spoilers, mounting system with adhesive set for easy installation on the roof of a camper or motorhome, as well as with solar cables and understandable assembly instruction.


This is how a solar power plant works in boats and yachts

For independent, silent and reliable solar power on board of the sailboat

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:

A SOLARA-module (e.g. M(Marine)-Series) for energy production
Optionally a special adhesive set for bonding the solar modules securely with the deck
A roof duct (item no. DD1 in white) for waterproof and permanent routing of the cable from the solar module to the charge controller
A charge controller with LED-display for monitoring the battery and charge indicator and to protect the battery against overcharging and reverse currents
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 four steps to a solar system with SOLARA for your sailboat

Step 1: Surface analysis

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.

Step 2: Determination of your daily power requirements

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.

Step 3: Selection of your SOLARA panels

Product recommendation: Solara M series, Power M series, S series

Step 4: Choosing the right charge contoller for your solar panels

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.

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