Natural gas is the main source of domestic production in Bangladesh, accounting for 75% of the country's trade power. The main source of electricity should be more to meet people's needs. Since there are a number of studies on the reliability of natural gas, it has finally caught the attention of the Bangladesh administration.

One of the major problems is that the country's energy distribution is unbalanced, and therefore most of the natural gas will account for the production of electricity. In that case, our government will have to take some advanced technological moves to meet the country's requirements. Also the current cost of the renewable energy system is quite new to it and it costs too much capital.

The energy gap is one of the biggest losses in Bangladesh and is a barrier to economic growth.

This type of violet depends on the control of the nuclear adjustment from the center of the sun. Currently, part of the biomass is biodegradable animal methane and automatically fuels alcohol production and electric power plants (Fig 2.4). Due to the necessity of life for the production of intrinsic hydrogen gas, the result is the pollution of the city's power plants.

Living from the first occupation of the planet and ranging from radioactive damage to heat, in every place, bites everywhere. This feasibility persists in some parts of the world, and several special summaries limit its utility. The second form of zyothal life is the heat of the living world, the vitality of the earth.

The primary commercial patent for a solar-based water radiator was awarded to Clarence Kemp in the United States in 1891. In 1839, the French physicist Edmund Bekele discovered that the sun's "photovoltaic effect" could be photographed (photo = light, voltaic = electric potential). In addition, the quality of supply is often unsatisfactory [31] due to load shedding and voltage variability.

Due to the negative environmental and social causes due to the construction of Karnaphuli power plant and the construction of reservoirs, long-term social unrest is created among the local population. The best thing about all the solar panel homes is that the solar bio is actually a permanent source of energy. We can't get rid of biographies based on the sun, unlike the work of another emerging speed.

Innovations in the solar powered energy industry will advance by the minute and citizenship will be closer. This is an example of the SHS Quality of Life Multi-Secret Connections between the Community Grid Community.

The electrons flowing out of the semiconductor's negative layer (n-type) flow to the positive layer (p-type) and supply an electric current. It is getting cheaper to make energy from sunlight based vitality and much of the time it is currently aggressive with vitality from coal or oil. A series of the wind turbine's solar PV frame consists of solar oriented table, charge controller, batteries, inverter and the heap.

The resistance should be kept as low as possible to minimize loss of electricity. While they have a fairly short lifespan and are shorter than other types of batteries, they are also one of the most expensive choices currently available in the home energy supply segment. The majority of the new frameworks for building up vitality supplies in the home, similar to the, utilize some kind of synthesis of lithium particles.

The solar oriented panel in fig 3.7 produces dc power, but most household units and mechanical machines require air conditioning current. The following frames, fig 3.8, are equipment devices occasionally used in axis-mounted solar arrays to permit the location of solar-oriented plates to seek solar development. This allows it to more effectively follow the sun's true course directly over the course of the day.

In this framework, you can just use solar powered power when it is created and not put away by the imagination. The framework capacities in such a way - the battery is charged primarily by solar power and if not by EB control. At the time the battery is full, on the off chance that the solar oriented current is available - the pile is related to sunlight based current - regardless of when EB control is available.

When both the solar and EB controls are not accessible, the battery is supplied by a battery. Such a long warranty is in huge contrast to most items and is due to the unique development of PV modules. They are called "solar panels" because the sun is usually considered by astronomers to be the most powerful source.

If the DC voltage can be exceeded 30V, the total voltage DC component of the individual module is connected to the module.

Light one more cell, which generates electricity, the spaceships are usually designed with solar panels that can always be aimed at the sun, while the rest of the spacecraft continues almost as the tank's budding tank goes independently, the target. There are open circuit voltage, short circuit current, voltage at maximum power, current at maximum power, maximum power, fill factor, irradiance and temperature. Solar energy is one of the most important alternatives of the time because it will be attractive to invest in this sector for long-term benefits.

When measuring our data, we connected the irradiance meter (Fig 4.5) to the photovoltaic meter. Evolution is defined as a measure of solar energy and it is decreasing solar energy on a surface. In the case of solar immersion, we typically measure the strength of each unit area, so the separation is usually quoted as w / m² - that is per square meter per watt.

Another commonly used term is "peak solar hour", which reflects the energy received during the daylight hours, which is determined by the same number of hours when the solar energy reaches an estimated 1000 watts / m2 total energy value. A temperature sensor (Figure 4.6) needs a thermocouple or RTD (resistive temperature identifier) to measure temperature through an instrument, an electrical signal. A thermocouple consists of two different metals that produce a proportional to atomic voltage to change temperature.

If the voltage increases, then the temperature increases and there is a voltage drop across the base and emitter terminals of the transistor, which is recorded. If the voltage difference increases, then the device generates an analog signal and is directly proportional to the temperature. The solar panel connected the whole meter, then the data here is the photovoltaic meter.

On a rainy day and low light, solar radiation is low, so there is no data for that day. All data set are maximum power, open circuit voltage, short circuit current, maximum power voltage, maximum power current, duty factor and irradiance.

DATA ANALYSIS

Introduction
Result
Comparison of Solar Radiation Data among Different Years
Summary

During the sunny day we got the highest value and for rainy day we got the lowest value. On July 10, 2018, the highest value of solar radiation was measured which was 1213 W/m2 and on July 28, 2018, the lowest value of radiation was found which was 50 W/m2 and the main reason behind this situation was sunny day and rainy day. On August 6, 2018, the highest value of solar radiation was measured which was 1111 W/m2 and on August 25, 2018, the lowest value of radiation was found which was 47 W/m2 and the main reason behind this situation was sunny day and rainy day.

We get the total produced power from the solar panel and irradiation from the second toolbox. So when we measured the lower power (17.0 W) at that moment, the incident irradiance from the sun on the panel was less than the irradiance measured toolbox. Our main objective is to find out how much direct current we get from a solar panel or how efficient a solar panel is.

The purpose of collecting data from solar panels is to find out how much DC output a solar panel can provide per day. In Figure 5.17 we see by measuring the irradiation for both July and August that the irradiation of August is better than that of July. In the previous figure we saw that the average Pmax of July is 9.6 and the Pmax of August is 9.2.

We separately measured mean irradiance and Pmax for sunny day and rainy day for both month of July and August. By measuring both July and August, we analyze that the average radiation of August is good than July.

Figure 5.1 shows the data of solar irradiation of July 2018. On 01 to 31 July 2018, the highest value of solar irradiance was measured that was 500 W/m2 and the lowest value of the solar irradiance was measured that 143 W/m2, the main reason behind this
