Solar Panels Boat Refrigerator

Boatbuilder nordic tugs has seen increased customer demand for installing solar panels atop the pilothouse to silently charge the batteries and power the refrigerator freezer and lights.

Solar panels boat refrigerator.

Let s find out what may be best for the way you use your boat. The rf 16 model uses a total of 750 watt hours a day about 300 400 watts of solar modules depending on the climate. This is useful especially at nighttime or during power failures as there is assured continuous energy supply. At the time it was more than adequate for our needs even with a watermaker we were fully topped up by 11 am or noon most days.

But we had a propane refrigerator which we just changed to a 12v model. Not the high efficiency ones with sunpower cells they will produce around 1 4 of the rated watts output in amp hours per day. If the boat has normal monocrystalline solar panels i e. Not taking into account conversion losses that s enough electricity to power a mini fridge for 24 hours or power a boat s gps display for 10 hours.

The frigid rigid solar refrigerator freezer is the only portable solar refrigerator freezer on the market that is engineered to be in the outdoors. Typically most rvs come with a 3 way refrigerator. The solar panels will charge the battery and keep it ready to supply power to your fridge. Now that speaks volumes about reliability dependability and ruggedness.

Your refrigerator is designed to run on propane gas or shore power. The solar panels have to be connected to a battery and inverter to provide power to your fridge. In fact frigid rigid 115 ac refrigerator freezers have been serving the marine saltwater market for over 35 years. The photovoltaic cells then convert the solar energy into electricity which is later stored in a battery.

We put a 345 watt high voltage solar panel with a kid by midnite solar mppt controller on the boat last spring. Because you can t power a fridge on solar panels alone. That means the fridge operates either on propane gas or ac electric that is supplied from shore power or a generator. The number one question i get asked all the time is can i power my fridge using solar short answer is no.

With the same danfoss compressor as the sunfrost these are smaller refrigerators but use about the same power. If the panels are made with sunpower cells then count on needing only 75 watts 25 amp hours x 3 75 of these higher efficiency rated panels to do same job. Novakool products are smaller dc powered refrigerators made for rv marine markets. So with these types of panels the boat will need at least 100 watts 25 amp hours x 4 100 of solar just to keep the fridge and freezer running.

One 100 watt solar panel that receives direct sunlight for 5 hours will produce approximately 500 wh of electricity 5 hours x 100 w 500 wh. The solar refrigerators are equipped with solar panels for the collection of solar power. At night there will be no power for the fridge and it will shut off.
