How To Choose The Boat Solar Panel System Kit?

For a long time, wind power has been the main form of marine energy-saving power generation. The low price and accessible wind resources are the conditions for the rapid promotion of wind power on ships. However, with various drawbacks of wind power have been exposed in the application, and the continuous development of solar energy technology, boat solar power has replaced wind power. The cost of boat solar power panel system is lower than that of wind power system on the market. Boat solar panel system has gradually been widely used as a new, reliable and environmentally friendly boat power system. The solar panel system is a device that uses solar energy to generate electricity, usually composed of solar panels, batteries, solar controllers and inverters. The direct current(DC) generated by the solar panels is converted into alternating current(AC) used by the loads on the boat, providing stable and reliable power supply for electrical equipment such as lighting, air conditioning, refrigerators, navigation, and communications on board.

Boat solar panel system structure

1. Solar panels: Solar panels are the core components of solar systems, and their function is to convert solar energy into direct current(DC). Common solar panels include monocrystalline silicon, polycrystalline silicon and thin-film solar panels. Monocrystalline silicon solar panels have a higher conversion efficiency, which can reach about 20% - 25%; polycrystalline silicon solar panels have a slightly lower conversion efficiency, usually 15% - 20%, and the cost is relatively low; thin-film solar panels are light and flexible, and can adapt to some special installation environments, but the conversion efficiency is low, between 10% - 15%.

2. Solar controller: The controller is responsible for the charge and discharge control between the solar panel and the battery to ensure that the battery will not be overcharged or over-discharged. At the same time, it can automatically adjust the charging state according to the output voltage and current of the solar panel to achieve the best charging effect. For example, when the battery is fully charged, the controller will automatically cut off the charging circuit; when the battery is too low, it can control the on and off of the load to protect the battery.

3. Battery: As the energy storage of the whole system, the battery can store the electricity obtained by the solar panels during the day for use at night or on cloudy days when there is insufficient light. Common types of batteries include lead-acid batteries and lithium-ion batteries. Lead-acid batteries are mature in technology and cheap in price, but have low energy density and short cycle life; lithium-ion batteries have high energy density and long cycle life, but high cost.

4.Inverter: Since solar panels generate direct current(DC), and most electrical equipment requires alternating current(AC), the inverter converts the direct current(DC) generated by the solar panels into alternating current(AC) to meet the power demand of the AC electrical equipment on board. According to the output waveform, the inverter can be divided into square wave inverter, modified sine wave inverter and pure sine wave inverter. The AC waveform output by the pure sine wave inverter is the same as the mains, and it is compatible with all types of electrical equipment, but its price is relatively high.

The role of boat solar panel system

Reduce operating costs: Solar panel systems require a certain amount of investment in the early stage, but in the long run, boat solar panel systems can reduce operating costs and increase economic benefits.

Power supply: The solar panel system uses solar power to provide various power supplies for electrical equipment on board, such as lighting, television, refrigerator, communication and navigation (GPS, radar) and other equipment, to meet the different power needs on board.

Increase ship safety: Boat solar energy can provide backup power for ships to deal with emergencies. During sea voyages, power failures caused by various reasons are very common, and solar energy can provide emergency power guarantee for ships when there is sufficient sunlight, which increases the safety of ships during navigation.

Reduce fuel dependence: Boat solar energy can reduce fuel dependence for ships and reduce fuel consumption. With the rising fuel prices today, boat solar as an economical and affordable new energy has attracted more and more attention and application. Solar power is a relatively stable, reliable and cheap energy source for boats, and its future development prospects are also very impressive.

Self-sufficiency: Even if the off-grid solar system sails for a long time away from ports and power grid areas, the ship can obtain a stable supply of electricity.

How to choose suitable boat solar system?
