INTRODUCTION
Developing countries like Bangladesh
are very much gullible to the current
energy crisis.
Alarming news -mineral resources (gas, fuels etc.) will
be consumed totally within a short interval in future
where electricity production dependent.
So, have to reduce dependence on mineral
resources rather focus the potential non-exhaustive
sustainable sources of energies resources
(solar,
biomass,
biogas and wind etc) available in the country.
INTRODUCTION
For this, UN recently
Declared SDG-2030 for
challenging the
climate change.
Annual amount of
solar energy reaching
surface is about twice as
much as ever be obtained
from all Earth's non-renewable
resources of coal, oil, natural gas, and uranium combined.
Bangladesh is a subtropical country.
huge potentiality and scope of solar plant
alter of non-renewable energy.
INTRODUCTION
Provide an environmentally sustainableenergy security,
Solar power plant in urban area to minimize increased burden of electricity in city
Affordable solar plant to the off-grid rural areas where [about 20% of the rural and remote people in Bangladesh are deprived from electricity]
Accordingly, effective utilization of solar energy resources has adopted as a policy of the (GOB).
Different government and NGOs have been working separately or jointly to disseminate solar energy technologies.
LITERATURE REVIEW / PREVIOUS STUDY
1. Solar power generated electricity is environmentally feasible and ample opportunity in Bangladesh and top priority for Bangladesh in the 21st century. [Khalequzzaman-07]
2. Government and NGO offices,
-health centers, -schools, -banks,
-police stations etc in off-grid
locations are either
using traditional
means (lantern, candles,
kerosene, wick lamps etc.) or own diesel genets
where offices can be easily served
With solar photovoltaic applications to reduce separate budgets.
Develop a policy framework -allows and inspires private investors to develop renewable energy projects to
realize the vast potential .[Islam and Islam (2005) ]

3. Higher usage of solar energy - will develop the sustainability and socio-economic development of the country.
RET(Renewable Energy Technologies) projectsneeds to be extensively carried out with the help of research and development and usage of proper equipment.

4. Average annual sunlight hours in Bangladesh compared with other developed countries like Germany and Spain, notable for development in solar energy sector.
[ Sakir, Rahman and Shahadat -2012 ]
LITERATURE REVIEW / PREVIOUS STUDY
5. Habib and Tamzid,(2001) explored a new efficient, suitable and robust hybrid model to overcome lacking of power supply in rural-remote areas by installing affordable solar power plant for rural areas people.
6. Considerable opportunity exists in Bangladesh to meet future power demand and thus economic growth. [Rahman and Saha (2013) ]
7. A solar PV system is important emerging option to supply electricity with quality
light, reliable service, and long-term
sustainability.

HYPOTHESIS
Potentiality and prospects of solar
energy in household and business
sectors in Bangladesh to reduce the
power crisis.
RESEARCH METHODOLOGY
Data collection
both factual and exploratory research approaches.
qualitative statistical analysis using primary data
Respondents: 177respondents from various
household and business sectors selected rural and
urban areas in Dhaka districts.
A questionnaire with eleven questions have
been structured followed by a two point Binary-
scale scheduling as follows:
YES= (1)
NO= (0)
RESEARCH METHODOLOGY
Tools used for data analysis
Data analysis and Purification was conducted
through SPSS version 16.
Factor analysis -to specify the basic issues for
using of solar energy as the alternative of electricity
in household and business sectors in Bangladesh.
multivariate method
for data reduction
purpose.

DATA ANALYSIS AND FINDINGS
This results shows - all factors have strong influence on
potentiality of using solar energy as the sustainable energy in
household and business sectors in Bangladesh.
The result displayed-
consent of respondent varies from factor to factor.
People of unavailable electricity area are using solar at lower
installation cost .But most of them are interested to use solar
energy if no restriction of limited use .
DATA ANALYSIS AND FINDINGS
Two perspective-
1. majority respondent of unavailable electricity area
agreed to prefer using solar energy despite problem of
limited use.
2. majority respondents of available electricity area are
reluctant to use solar energy due to
a. a. delay limited use,
b. b. higher installation cost as well as
c. c. less advantages than electricity.
DATA ANALYSIS AND FINDINGS
Loadings 11 variables that
4 factors extracted [between 4
and 5 factors Eigen value 1]
Factor 1- found Idea about
solar power, usages at home,
satisfaction over solar energy,
user convenience and better advantages of solar power rather than electricity
Factor 2- Influencing the
potential greater scopes for
using solar energy as sustainable power modes.
Factor 3- enhancing solar power’s technological
advancement
Factor 4- limited use of solar energy: main
constraints to choose solar energy
Factor analysis
CONCLUSION:
This current study has explored several-
external reasons like- (advantages)
satisfaction over solar energy,
user convenience and
comparative advantages of solar energy as well as
internal reasons like- (disadvantages)
higher installation cost of solar energy,
limited use,
servicing/maintenance cost
which have major impact on potentiality of using solar energy in
household and business purposes.
CONCLUSION AND RECOMMENDATION
Going forward, we can’t say that people are chosen
to solar energy against electricity
maximum unavailable electricity area people are
tend to use solar energy as no alternative power
supply.
Recommendation- If emphasizing on the
increased capacity and efficiency of solar power
plant,
--the use of solar power plant will be raising
rapidly throughout the country in household and
business sectors.
CONCLUSION AND RECOMMENDATION
On the contrary, the available electricity area people are quite reluctant to use solar power plant due to its limited use, higher installation cost and also unusualness with solar power plant.
Recommendation- If focusing on the
social awareness about the sustainable use of solar power plant and
by decreasing installation cost,
--the people in available electricity region will also be willing to use solar power plant to concise the use and decrease pressure on electricity.
Thus, current power crisis over country
will decrease at proportionally in
large scale
RECOMMENDATION
If it possible that maximum people are
gradually tend to use solar power plant, in near
future,----no power crisis in our country.
There is a possible way, especially in Dhaka
city including all city and town,
Authority can encourage city dwellers announcing
particular percentage of city tax redemption to
those who installs solar power plant in every building
of house as well as in business.
It might be very effective to reduce the huge
pressure on power supply through electricity.
