Performance analysis of Solar Roof-top System Under DPDC

Abstract

Bangladesh is a developing country facing many problems, lacks electricity shortage. The rural section of Bangladesh is the worst sufferers of this crisis having limited electricity or some rural has no grid electricity. Solar energy has been proven to be a very promising resource to improve the ongoing electricity shortage. The mining of non-renewable energy and the by-products they leave behind cause damage to the environment. When fossil fuel is burned, nitrous oxide causes photochemical pollution, sulphur dioxide creates acid rain and greenhouse gases are emitted. Moreover, fossil fuel is finite in amount and cost a lot of money as well. Hence, renewable energy is a potential solution to meet up the electricity demand for the developing country like Bangladesh. Along all the renewable technologies, Solar system is most potential technology which convert solar energy to electrical energy. The sun shine on the solar panel generating “DC” (Direct Current) electricity. The electricity is fed into a solar inverter that converts into “AC” (Alternating Current) current. The AC electricity is used to power appliances in our country. The government wants to fill up 10% of the demands of the electricity supply of solar energy within 2020. To accomplish the demand, Government established a rule that if any consumers get a new electricity connection they must build up a solar rooftop system. To follow the policy, DPDC provides SRS system to their new consumers. We visited some of those consumers according to the list provided by DPDC in Narayanganj area. We have tried to know about various types of consumer information from the users of the SRS system. According to the questionnaire form, we checked those SRS whether the systems are in operation or not. We collected the meter readings and calculated per unit cost from the system under operation. Many of the systems were not in operation properly, we tried to know the reason behind it. Moreover, we tried to find out the brought condition of the SRS system as well. We asked them whether they clean their solar panels or not and if they get any kind of training for solar operation from the government organization or private agency. Our main purpose was to find out the satisfaction of the consumers about how many of them are being satisfied with the system and how many of them are not. After all the preceding information, we informed them about the net metering system and usefulness of SRS.
