Power is one of the most important factors in developing countries and for sustainable economy. Like the rest of the countries of the planet, the demand for power in Bangladesh is increasing day by day. The main purpose of our research is to find out the irradiance of sun in Dhaka city in September month so that the power production by the solar panel can be estimated and we collect the solar irradiance and the maximum power data in Dhaka for (September)0ne month and analyze the data to get average irradiance and find the relationship between solar irradiance and power and by using this data we can easily understand the electricity production by solar home system and create a standard form of power production of solar home system in 2018. This research is an attempt to the analyze socio-economic impact using solar Home System and also test the feasibility of maximum power that can be generated from the panel.
The social and economic development of SHS and their prospects, challenges and limitations can be estimated using a specific method called SWOT analysis. Introduction to the Solar Home System (SHS), current state of the Solar Home System, future prospects of the Solar Home System.

By establishing this, the user of Solar Home system (off grid, on grid, Micro grid, mini grid, Roof top) is increasing day by day. It seems that grid solar development has so far failed to deliver realistic hope. Most of the users in Bangladesh are not properly trained to maintain the solar system or get the maximum output.
After collecting the data, we made a unit calculation for average peak power and feasibility test for the Solar Home System in a rural village. Our study will essentially focus on the socio-economic impact of home solar system use.

We can produce renewable energy from moving water just as we can from moving air. Solar energy, radiant light and heat from the sun, is harnessed using a variety of constantly evolving technologies such as solar thermal, solar cell systems, solar thermal electricity, solar architecture and artificial photosynthesis. The amount of electrical energy produced by photovoltaic cells is proportional to the power and angle of the light reaching the unit area.
But the government has focused on renewable energy, such as solar energy, wind energy and hydropower. Commendable progress has been made in the renewable energy sector in recent years.

We found that most of the panels in this village are above the roof. But the height of the tree is even greater than the board. In Bangladesh, most building roofs, both commercial and privet, are not used for. Most roofs in commercial and residential buildings are completely or partially empty.
According to the government's plan, renewable sources should provide about 10 percent of the total energy production capacity by 2021, which means 2,400 MW of energy production from renewable sources. Keeping this in mind, the Government and also some Privet organizations have taken a part of the project to realize it. Solar energy is one of the most potential sources of renewable energy in Bangladesh as solar radiation falls on average 5 kWh/m2 with over 300 sunny days per year.
Just as there are many countries in Antarctica where the sun does not shine fully most of the time. It is also one of the largest cities in South Asia, with a population of around 12 million people. They can connect to the outside world, so they are more social than before, which also creates an interest in education.
They can use mobile phone or TV so that they can get information from outside the world for agricultural information, health information and some for entertainment purposes. Even now the SHS program has about 438000 SHS with the help of the main contributor GS which is a partner organization of IDCOL. Basically we have completed our survey in a small region of Bhola district, Upozilla-Monpura, Bangladesh.

The acquired data is then treated to anticipate the I-V characteristic under standard test conditions (STC) and compare with rated data. Irradiance and temperature sensor play a tremendous role for extrapolation of the I-V characteristic under the standard test conditions.

Voc = Solar panel open circuit voltage Isc = Solar panel short circuit current Vmpp = Solar panel maximum voltage Impp = Solar panel maximum fill factor current = (Impp*Vmpp)/(Isc*Vsc) Pmax = Maximum power. Basically primary data collected from internet, from literature, interviews with solar home system user. General information about the SHS distribution program and socio-economic impacts of solar electricity were collected from secondary source and interviews with local experts.
The study's primary data is collected through a comprehensive household survey and the off-grid solar method using a questionnaire. To observe these issues, we had to collect data from the implementation area, such as the size of the panel (PV cell panel), and battery size, number of loads, number of electrical gadgets, future requirements, monthly income of the villagers. have analyzed the data after communicating with local people. We discussed with the people about their financial and family condition so that we can suggest them to install the right size of the panel. Then we made some specific data series to evaluate the panel size, battery size and other accessories. The special series are – Number of family members and level of education vs.
After observing all the data, we can find the right size of the panel and the required battery.

In our solar laboratory, we have calculated the total energy unit cost of renewable energy. According to us, we have chosen another specific method called SWOT analysis for social and economic data analysis. Suppose we have such a weather where the irradiance is too low so we cannot install the solar Home system.
We have collected the value of irradiation in the year 1985 to 2018. We have seen that in 1985-1991 the irradiation was 3.96 kWh/m2/day and then increased randomly until the year 1992. Then in the year 2000 again the irradiation began to wear off. Microfinance is the most important part of the sustainable electrification of any rural area. Microfinance is basically a short-term loan for socio-economic purposes. For rural communities like Monpura, we have found that the entire family is funded by an organization.
The disadvantage of the solar home system for this region is something that affects the actual development. So unit costs have increased. We have calculated the unit cost for our survey area "Monpura". We analyzed the irradiance pattern for solar electricity generation in Bangladesh and also the socio-economic impact of using solar electricity in a rural village.
We also calculated and plotted the power from the panel to identify the power variation. This figure shows the Total panel size (W) for individual income and total load for individual load (w).
Increased Student Number
Summery
We have seen that the unit cost for our solar cells from our solar lab is lower than SHS in our research area. We have seen that a lot of development is possible if the government monetization increases, the technology used.
CONCLUSION
Introduction
Future scope of this work
- Enhancing productive use of Solar Home System
- Enhancing socio-economic condition
An increased perception of safety and social activity due to social gatherings while watching television and listening to the radio is also observed in SHS-owned households. Every community clinic and union health center could be electrified with SHS and thus community residents can get health facilities using SHS vaccine refrigeration and operation in rural health clinics. But the children of rural poor families studying in an educational institution of a remote village cannot use the computer and internet in their institution.
By providing SHS with computers and internet in those institutions, the marginalized poor student could be swept into the mainstream of development. Research shows that watching TV and listening to the radio is most often done in the evenings by household members. To increase the benefits of TV and radio, educational TV and radio programs can be implemented.
Since most of the household uses a mobile phone, more messaging awareness programs can be offered. Electrification by SHS at the cyclone center or flood center ensures better management of the affected people as it allows communicating vaccines, water conservation, cooking, heating and public health information through TV, radio and mobile phone. In remote areas of Bangladesh, people do not feel safe at night due to sufficient light.
Village street lighting can be possible by using SHS, which increases the safety of rural people at night. This can help improve the law and order situation in remote villages and thus ensure good governance.
