<span lang="EN-US">This paper describes the design of an LED lamp to be used in a DC house being supplied using a renewable energy source or in a DC Smart Grid. LED lamps are widely known for its low-electricity consumption. The DC house application is becoming more and more popular due to its advantage of using DC generated electricity, for example from a solar photovoltaic system, directly without having to invert it into AC voltage. However, LED needs a driver to activate and control it. Its mounting also needs certain precaution to anticipate the high heat from the LED. An appropriate heatsink is required before activating the LED. The laboratory results indicate that a 3-watt LED bulb lamp can produce an efficiency up to 93.16% with luminous efficacy 82.29 lm/W. These results prove that an LED bulb consumes less energy and can give an optimal brightness.</span>

In solar photovoltaic (PV)-based DC microgrid systems, the voltage output of the classical DC–DC converter produces very less voltage as a result of poor voltage gain. Therefore, cascaded DC–DC boost converters are mandatory for boosting the voltage to match the DC microgrid voltage. However, the number of devices utilized in the DC–DC conversion stage becomes higher and leads to more losses. Thereby, it affects the system efficiency and increases the complication of the system and cost. In order to overcome this drawback, a novel double-boost DC–DC converter is proposed to meet the voltage in DC microgrid. Also, this paper discusses the detailed operation of maximum power point (MPP) tracking techniques in the novel double-boost DC–DC converter topology. The fundamental [Formula: see text]–[Formula: see text] and [Formula: see text]–[Formula: see text] characteristics of solar photovoltaic system, operational details of MPP execution and control strategies for double-boost DC/DC converter are described elaborately. The proposed converter operation and power injection into the DC microgrid are verified through the real-time PSCAD simulation and the validation is done through the experiment with hardware module which is indistinguishable with the simulation platform.

In today’s world we are going towards the major share of renewable energy to reduce the effect Green House Gases (GHG) in the atmosphere. The limitation of energy sources which produces clean energy, the rise in the pollution in the environment, and programs initiated by the Indian Government have encouraged lots of open field researches on Solar Photovoltaic Systems or Solar Energy Systems. As producing the clean and renewable energy is main component of energy sector, solar photovoltaic could be considered as an alternative in various regions. Although Solar Photovoltaic does have different advantages and can be used for various purposes, but also there are several challenges for it. This paper took a whole overview of the advantages and uses of Solar Photovoltaic and barriers in their adaptation/opportunities.

Photovoltaic Solar Energy

Photovoltaic solar energy is a clean renewable energy source that allows obtaining electricity directly from solar radiation through semiconductor devices called photovoltaic cells. The present research aims to pre-design an isolated system for a house that can serve as a pattern for the electrification of houses that today do not have power in the province of Manabí. To carry out the proposal, the PVsyst was used, a tool for sizing the system, in addition to the bibliographic review, the qualitative-quantitative, and the inductive deductive. It was obtained as a result that photovoltaic solar energy is adequate to provide a solution to isolated homes that today do not have energy service, in addition to those that have a poor quality of service.

Solar Photovoltaic System

Countries like Malaysia have more that 70% of its population living in rural areas. Majority of these rural areas lie in regions where most villages do not have grid connected electricity. Renewable energy using photovoltaic (PV) panels offers an alternative and cost efficient solution that exploits the yearlong abundance of sunlight available in countries like Malaysia. The main problem with PV systems is the high maintenance costs in replacing batteries every few years which makes PV systems unattractive for rural areas. A full scale PV system, developed in Semenyih Malaysia, aims to increase battery lifetime and reduce maintenance costs by incorporating supercapacitors. The system was developed in a life-sized cabin to mimic a rural home. A programmable load is used to test the system with the load profile of a typical rural household usage. Experimental and simulation results show that the supercapacitor bank is able to reduce the stress on the battery by absorbing peak current surges. Results also show that the system is able to maintain a high battery state of charge during the entire day.Article History: Received June 17th 2016; Received in revised form August 16th 2016; Accepted Sept 10th 2016; Available onlineHow to Cite This Article: Fahmi, M.I., Rajkumar, R.,  Wong, Y.W., Chong, L.W., Arelhi, R., and Isa, D.
