Indonesia, which is a tropical country, has a very large potential for solar energy because of its area that stretches across the equator, with a radiation magnitude of 4.80 kWh / m2 / day or equivalent to 112,000 GWp. On the other hand, the earth receives solar power of 1.74 x 1017 W / hour and about 1-2% of it is converted into wind energy. However, from the total energy potential, Indonesia has only utilized around 10 MWp for solar energy and not much different, wind energy, whose utilization is planned to reach 250 MW in 2025, has only been utilized around 1 MW of the total existing potential. With this potential, to be able to supply additional power and help save energy for existing facilities in the building, a Prototype of Solar Panel Hybird and Vertical Axis Wind Turbine was created. The design of this prototype is a combination of savonious type turbines and solar panels, where the use of this type of turbine is because it can rotate at low wind speeds (low wind velocity) and its construction is very simple.

Solar or solar energy can be an alternative source of energy in the future, where solar energy can be converted into electrical energy by utilizing the photoelectric effect that occurs in photovoltaic components or solar cells.  Solar cells or photovoltaic components can convert sunlight into electrical energy that can be used directly by the load or stored in a battery, a kind of electrochemical device that can store electrical charges in the form of chemical energy. The electrical energy generated by the solar cell is influenced by the intensity of light received by the sun. To gain the desired power and voltage, the solar cells are connected in series and parallel into a solar cell module. 2N3055 & MJ2955 transistor based solar panels are the basic materials for designing alternative power generation. In the process of manufacture, this solar panel utilizes the components of used components that are still feasible to use, so it can be used to be the appropriate technology to produce a solar panel that utilizes solar energy in the form of sunlight and solar heat. In this study also conducted experiments using glass components as a reflection effect from light sources. The result of this experiment obtained that the amount of electrical energy output resulting from the reflection effect of light by using 2N3055 transistor and MJ2955 transistor can produce increased current and increase electrical power.Keywords: Solar cell, Transistor 2N3055 & MJ2955, The effect of reflection light

Solar Panels

In recent years the use of solar energy is found to have grown by a large amount. Solar energy is renewable energy and the demand for it as clean energy shows its growth by nearly 50 percent in the past decade. It is estimated that the sun is able to generate energy within 24 hours that the entire population of the world could consume in 27 years. Solar power is the energy from the sun that is converted into thermal or electrical energy. The energy harnessed from the sun's rays is used for a variety of applications like electricity generation, to provide light for the interior environment, and many other domestic, commercial, and industrial purposes. Usage of fossil fuels for electricity production results in increased pollution and this mandates many governments to encourage moving to electricity generation using solar power. The large amount of solar energy that is available is found to be the most appealing source of electricity. Solar panels form a major part of the solar energy setup. Hence in this article let us review the various types of solar panels. This paper also deals with comparing the merits and demerits of the different types of solar panels that are available in the market. A section that presents the efficiency of the different kinds of the solar panel is also present in this paper. The role of temperature coefficient, fire rating, and hail rating in the performance of the solar panel is also addressed in this paper.

Renewable energy is of great importance for today’s world which is generally produced from natural sources. Countries like Bangladesh has to use this energy to meet their energy demand. Day by day the demand of electricity is increasing in stormy pace but our resource is limited. So using renewable resources i.e. solar power to meet the demand of electricity is highly necessary especially rural and remote areas. This paper examined the nature and extent of solar energy in Boyarjapha village of Paikgachha Upazila of Khulna district to analyse the effects of solar panel in their daily life. Many positive impacts of solar power were found out such as better quality lighting, education, entertainment, communications, business, increasing working hours, women empowerment, increasing awareness etc. There are a few bad effects of solar energy too. But Government intervention is a must to ensure better quality results in coming future. Similarly, government has to take serious steps to advertise solar electricity in remote areas of Bangladesh

Indonesia is a country that is geographically located right in the equator and variously advantage and the wide for the use of solar energy. Indonesia has a relatively high radiation level, which is 4.80 kWh / m2 / day. Cemara Island is a tourist place but does not have electricity from PLN because access to its location is still difficult to reach. So from that chosen the planning system for the use of electrical energy using solar energy. However, economic analysis is needed so that the estimated weaknesses of the off-grid solar system can be estimated so as to reduce the risk of losses. The testing of each component in the Solar Power Plant system also needs to be done to determine the condition and quality of the components to be used. The economic analysis of the Cemara Island Solar Power Plant System with an initial investment of Rp 52,553,000, in scenario 1 uses interest at 6%, then in scenario 2 without using interest. Through calculations by looking for the value of COE (Energy Cost), NPC (Net Present Cost) and BEP (Break-Even Point), so that costs can be calculated by the manager with the number of 11 managers per month.
