Solar-powered sightseeing vehicle manufacturer: Some basic knowledge about solar energy

The manufacturer of solar-powered sightseeing vehicles believes that solar power generation is a photovoltaic technology that converts solar radiation energy into electrical energy using solar cell arrays. The working principle of solar cells is based on the photovoltaic effect of semiconductor PN junctions. In simple terms, the photovoltaic effect refers to the phenomenon where, when an object is exposed to light, the distribution of electric charges within the object changes, thereby generating an electric potential and current. 

The manufacturer of solar-powered sightseeing vehicles believes that the solar power generation system consists of solar panels, solar controllers and batteries (groups). If the output power is 220 volts or 110 volts alternating current, an inverter is also required. The functions of each component are: 

Solar panels: Solar tour bus manufacturers consider solar panels to be the core component of the solar power generation system and also a valuable part of it. Their function is to convert the radiation power of the sun into electrical energy, either sending it to the battery for storage or driving the load to operate. The quality and cost of the solar panels will directly determine the quality and cost of the entire system.

2. Solar Controller: The function of the solar controller is to control the working status of the entire system and protect the battery from overcharging and overdischarging. In areas with significant temperature differences, a qualified controller should also have a temperature compensation function. Other additional functions, such as light control switches and time control switches, should be optional for the controller. 

3. Battery: Generally, it is a lead-acid battery. The manufacturer of solar sightseeing vehicles believes that in small and micro systems, nickel-metal-hydride batteries, nickel-cadmium batteries or lithium batteries can also be used. Its function is to store the electrical energy generated by the solar panel when there is light, and then release it when needed. 

4. Inverter: Solar-powered sightseeing vehicle manufacturers believe that in many cases, 220VAC and 110VAC alternating current power sources are required. Since the direct output of solar energy is generally 12V DC, 24V DC, and 48V DC. To provide power for 220VAC electrical appliances, the direct current generated by the solar power generation system needs to be converted into alternating current, thus a DC-to-AC inverter is required. In some cases, when various voltage loads are needed, DC-to-DC inverters are also used. 

The manufacturer of solar-powered sightseeing vehicles believes that the advantages of solar energy are: 

Solar energy is an inexhaustible source of clean energy; moreover, it is not affected by energy crises or instability in the fuel market. 

2. Solar energy is available everywhere, so solar photovoltaic power generation is particularly suitable for remote areas without electricity. At the same time, it reduces the construction of long-distance power grids and the energy loss on transmission lines. 

3. The generation of solar energy does not require any fuel, which significantly reduces operating costs. 

4. Besides the tracking type, solar photovoltaic power generation has no moving parts, which makes it less prone to damage and easier to install and maintain. 

5. The manufacturer of solar-powered sightseeing vehicles believes that solar photovoltaic power generation does not produce any waste, nor does it generate noise, greenhouse gases or toxic gases. It is an ideal form of clean energy. 

6. The manufacturer of solar-powered sightseeing vehicles believes that the construction period of the solar photovoltaic power generation system is short, the lifespan of the power generation components is long, the power generation method is flexible, and the energy recovery period of the power generation system is short.
