1. Solar lighting system Introduction:

Compared with the commonly used thermal power system, the advantages of photovoltaic power generation are mainly reflected in:

(1) no risk of exhaustion;

(2) safe and reliable, no noise, no pollution emissions, absolutely clean (pollution-free);

(3) not limited by the geographical distribution of resources, can use the advantages of building roof;For example, areas without electricity, and areas with difficult terrain;

(4) No need to consume fuel and set up transmission lines to generate power locally;

(5) High energy quality;

(6)Users are emotionally receptive;

(7)The construction cycle is short and the time spent to obtain energy is short.

2.Development status of solar photovoltaic system

Solar photovoltaic power generation is the most bright future prospects for development of new energy use one way, as the future of our country continuous optimization of energy structure and national policies and regulations, systems and mechanisms in the development of new energy gradually perfect, the development of photovoltaic industry will enter a new high-speed development of the "honeymoon period".Although solar photovoltaic application market development in China started late, and the developed countries in the aspect of development of photovoltaic power generation there is a big gap, but as in the use of new energy policy in China in the future of gradual adjustment, the domestic photovoltaic market will get rapid development and expansion, solar photovoltaic power generation will also be a place in our country electric power industry.

3. Introduction to solar photovoltaic panels

Monocrystalline silicon

Mass production conversion rate: 19.8 -- 21%;Most were at 17.5%.Breakthroughs that increase efficiency by more than 30% are now less likely.

polysilicon

Mass production conversion rate: 18 -- 18.5%;Most are at 16%.Like monocrystalline silicon, it is less likely to reach a conversion rate of more than 30% due to material physical property limitations.

4.Composition of solar power generation system

The solar power generation system is composed of a solar battery group, a solar controller and a battery (group).If the output power supply is AC 220V or 110V, an inverter is also required.

The functions of each part are:

(1) Solar panels: solar panels are the core part of the solar power generation system, and also the most valuable part of the solar power generation system.Its role is to convert the radiant energy of the sun into electric energy, or sent to the storage battery, or promote the work of the load.The quality and cost of solar panels will directly determine the quality and cost of the whole system;

(2) solar controller: the role of the solar controller is to control the working state of the whole system, and the battery plays the role of over-charge protection and over-discharge protection.In the place of large temperature difference, the qualified controller should also have the function of temperature compensation.Other additional functions such as light control switch, time control switch should be the controller should have the function;

(3) Battery: generally lead-acid batteries, nickel hydrogen batteries, nickel cadmium batteries or lithium batteries can also be used in small systems.Because the input energy of solar photovoltaic power generation system is extremely unstable, it is generally required to configure the battery system to work.Its function is to store the electric energy issued by solar panels when there is light, and then release it when needed;

(4) inverter: in many occasions, it is necessary to provide 220VAC, 110VAC AC power supply.Because the direct output of solar energy is generally 12VDC, 24VDC, 48VDC.In order to provide power to 220VAC appliances, it is necessary to convert the direct current energy from the solar power generation system into AC electricity, so the use of a DC-AC inverter is needed.In some cases, DC-DC inverters are also used when multiple voltage loads are required, such as converting 24VDC to 5VDC power.
