Solar Energy in Boats /

An important application area where solar energy systems are used is the maritime sector and marine vehicles. For example, solar energy systems in boats are often used for charging batteries and for service and backup energy.

Accumulators in boats may be charged as long as the boat engine is running or (if present) the generator is running, when not connected to shore electricity. However, this method causes extra fuel waste and environmental pollution when staying for long periods. The need for continuous refueling, cost and high levels of noise and exhaust gases are not at all comfortable.

Main Equipments Used in Marine Applications

Solar Panel / Solar Cell / Solar Panel / PV Module

Photovoltaic / Photovoltaic / Module

The solar panel is an essential part of the system and a basic electricity generator. It can be selected according to months, season and electrical devices to be operated in the system. Appropriate installation is done on the boat.

Battery Charge Controller / Solar Charge Controller / Charge Controller

In principle, it is an electronic device that automatically controls the power (voltage and current) from the panel to the battery. It ensures ideal charging / storage of the battery (s) without overcharging and discharging. Using 2 separate (dual) output Battery Charge Regulators, you can safely charge the starter and service batteries separately with the energy from the panel (for example).

Accumulator / Battery / Battery

The existing batteries in the system can be used or additional batteries can be used depending on the consumption and working time. Products suitable for marine applications, bottom discharge and high cycle (charge-discharge) should be preferred.

Solar Cable

First of all, it should be suitable / sufficient cross-section and resistant to climatic conditions. It should be selected in such a way that there is no loss on it according to distance and power.

PV Connector

It should be resistant to climatic conditions and should have an ideal conductivity structure. In winter, PVs should be easily removed and installed when necessary or during maintenance / service.
