Solar energy is becoming a new generation renewable energy source that can generate electricity by reducing the generation of carbon dioxide by replacing fossil fuel, petroleum, coal, and gas by replacing nuclear / hydropower / thermal power.

Photovoltaic power generation system is a system that produces electric energy by converting solar heat into electricity by reaching the earth from the radiant heat of the sun. It is a small-scale photovoltaic power generation system with a capacity of less than 100 kWp, medium-scale photovoltaic power generation with a capacity of 100 kWp to 500 kWp System, and a large-scale solar power generation system of 500 kWp or more.

The residential solar cell system can be used by having solar cell arrays (PV arrays) on the roof of houses and using them in a different system from the solar energy power supply system and / or the electric energy of a typical pillar transformer.

In addition, in the classification according to the type of load and the system line connection, the photovoltaic power generation system is classified into a stand-alone PV system and a utility-connection PV system.

Photovoltaic power generation is used as a photovoltaic module with solar cells (solar cells or photovoltaic cells) that convert sunlight directly into electricity. Each solar cell generates electron-hole pairs when solar light having energy greater than the band-gap energy of the semiconductor is incident on the solar cell made of the pn junction of the semiconductor, Electrons are collected into the n-layer and holes are collected in the p-layer by the electric field formed by the pn junctions of the semiconductors of the respective solar cells, and the photovoltaic power is generated.

A solar cell consists of a pn-junction semiconductor device that converts solar energy into electrical energy by photo-voltaic effect when sunlight is irradiated. In p-type semiconductors, many carriers are holes and minor carriers are electrons. In n-type semiconductors, many carriers are electrons and minor carriers are holes. Therefore, the PN of a solar cell When the junction is irradiated with sun light, electrons and holes generated by light (photon) are generated and the electrons diffused from the p-type semiconductor at the PN junction are an n-type semiconductor and an n-type semiconductor The holes diffused into the p-type semiconductor to generate an electromotive force. The n-type semiconductor and the p-type semiconductor respectively generate a direct current to the attached positive and negative electrodes.

For example, in the case of a single crystal silicon solar cell, the generation voltage of one solar cell is about 0.5 V when the solar cell of the solar cell is irradiated with solar light having a pn junction formed on a 10 to 15 cm plate-shaped silicon (Si) Each solar cell is connected in series to form a solar module.

Overcharge is caused when the battery rises above a certain voltage, corrosion occurs in the battery and gas is generated, which shortens the life of the battery. Over discharge means that when the battery is reduced to a certain voltage (for example, DC 23V), precipitates are formed in the battery, and the performance of the battery gradually decreases.

The battery 30 discharges electricity to convert electrical energy into chemical energy and charge the battery through the overcharge / over-discharge prevention circuit of the charge controller 20 and conversely to supply the load, And supplies electric energy.

The DC-DC converter 40 converts the DC current and the DC voltage generated from the solar cell array 10 and supplies the converted DC current and the DC voltage required by the corresponding device to the DC load 45 do.

The inverter 50 is connected to the charge controller 20 and converts the DC power source DC into an AC power source to supply the AC load 54 with voltage and current.

1. Lens-type collector cover for solar energy efficiency

Solar energy travels a great distance from the sun to the earth, and solar energy, including solar energy, penetrates deeper into a portable leisure and solar fan.

However, the principle of the solar heat fan is that the solar energy that is once introduced is used to escape from the heat sink of the solar hot-air fan, but is confined to the rear heat-insulating cover so as not to escape.

However, some solar energy can not be used because it is not reflected or lost or passed before entering the solar collector.

Therefore, the lens-type heat collecting portion cover 1 requires two requirements.

First, it should have good permeability so that solar energy can easily permeate.

Second, it serves as a cover for the solar cell to prevent the transmitted solar energy from being reflected and emitted.

In order to improve the condensing and collecting ability, the solar heat collector cover (1) processed by a lens is applied to collect the solar energy arriving at the cover of the solar heat collector and collecting the condensed light and the collected heat, Is introduced into the heat collecting portion of the hot air fan and processed by the lens so that the incoming solar energy is not reflected and lost, so that the efficiency is improved by staying in the heat collecting portion of the solar hot air fan.

The lens-type heat collecting plate cover (1) must have good permeability to improve the entry of solar energy, and should have good weather resistance against strong ultraviolet rays.

The size (area) of the heat collecting part has the greatest influence on the efficiency of the portable leisure-type solar heat fan.

As the size (area) of the solar heat collecting part increases, the area for collecting the solar energy increases, and thus the solar energy of the high temperature can be obtained.

However, there is a limitation in the size of the small size solar fan heater for the purpose of dragging the food drier for solar drying and the heat sink for leisure fan.

In order to minimize the size of the portable hot-air fan unit and to facilitate the movement thereof, and to improve the heat collecting ability of the solar heat collecting unit, various reflectors are required to have a large size effect without increasing the size thereof. Therefore, it has been devised to increase the heat collection efficiency by attaching the collecting reflector (2) to the left, right and lower sides.

It is generally known that the reflector area (2) increases by 30% with respect to the collector area.

When the reflective plate 2 is attached to the handle 7 and moved, the reflective plate 2 is brought into close contact with the cover surface of the lens-shaped heat collecting portion to improve the mobility. In addition, when the reflective plate 2 is installed, Respectively.

3. High-temperature energy production through improvement of heat insulation performance in collecting part

In order to improve the efficiency of solar heat fan combined with portable leisure, it is important to improve the heat insulation performance as much as the size (area) and the heat collection performance of the solar heat fan. In order to utilize the high-temperature energy, various kinds of elements are needed.
