Abstract--The interest in off-grid photovoltaic (PV) solar energy systems in villages and remote areas is increasing. This interest stems from several factors such as improvement in living standards, reduced capital cost, stricter environmental constraints, and national programs that encourage renewable energy systems. To promote the usefulness of such renewable energy systems, a simple design and cost analysis method was developed. Its purpose is system sizing and life cycle cost analysis. Key parameters such as energy consumption, storage requirements, solar resources and financing options are entered into the program. Results such as system size and project cost are computed. For the financial analysis, Internal Rate of Return and Payback Period are used as project evaluation techniques. The method was tested for four PV systems with different geographical conditions and energy consumption profiles. Results show that the PV systems can be attractive on economic basis if governments provide sufficient funding and incentives.

1. INTRODUCTION
Photovoltaics offer consumers the ability to generate electricity in a clean, quiet and reliable way. Because the source of energy is usually the sun, the electricity produced by PV systems is an attractive option for many countries close to the equator and sun-belt regions for many reasons.
For instance, this source of energy is emission and pollution free-a positive response to the current worldwide needs to reduce global environmental emissions. In fact, each one kW of PV-produced electricity offsets up to 16 kg of...

Photovoltaic White Paper

...Photovoltaic Power Systems Compiled by Tracy Dahl Overview Photovoltaic (PV) technology converts one form of energy (sunlight) into another form of energy (electricity) using no moving parts, consuming no conventional fossil fuels, creating no pollution, and lasting for decades with very little maintenance. The use of a widely available and reasonably reliable fuel source—the sun—with no associated storage or transportation difficulties and no emissions makes this technology eminently practicable for powering remote scientific research platforms. Indeed, numerous examples of successfully deployed systems are already available. The completely scaleable nature of the technology also lends itself well to varying power requirements–from the smallest autonomous research platforms to infrastructure-based systems. This technology can be limited, however, by annual fluctuations in solar insolation, especially at extreme latitudes. Based on semiconductor technology, solar cells operate on the principle that electricity will flow between two semiconductors when they are put into contact with each other and exposed to light (photons). This phenomenon, known as the photovoltaic effect, was first discovered by Edmund Becquerel in 1839. Actual development of PV technology began in the 1950s and gained greater impetus through the NASA space program during the 1960s. Research continues today at national laboratories and within private industry, focusing on increasing conversion......

...Renewable Energy Diffusion Potential India a b s t r a c t A majority of the Indian population does not have access to convenient energy services (LPG, electricity). Though India has made significant progress in renewable energy, the share of modern renewables in the energy mix is marginal. This paper reviews the status and potential of different renewables (except biomass) in India. This paper documents the trends in the growth of renewables in India and establishes diffusion model as a basis for setting targets. The diffusion model is fitted tot the past trends for wind, small hydro and solar water heating and is used to establish future targets. The economic viability and green house gas (GHG) saving potential is estimated for each option. Several renewables have high growth rates, for example wind, Photovoltaic (PV) module manufacture and solar water heaters. New technologies like Tidal, OTEC, Solar thermal power plants and geothermal power plants are at the demonstration stage and future dissemination will depend on the experience of these projects.

Off Grid Renewable Energy

...rural areas and find it geographically challenging to benefit from grid-connected electricity for power supply. In the developing countries, rural areas mainly rely on inconvenient non-commercial resources like wood, agricultural residues etc. as sources of power generation. Hence, Off-Grid power, which can be generated on-site from renewable energy sources such as solar, wind and biomass, plays a major role for the future of rural electrification world-wide. To achieve universal access of electricity, International Energy Agency (IEA) estimates that by 2030 about 171 TWh of Off-Grid electricity will need to be generated for providing power to approximately 210M or 20% of total rural households. This paper focuses on understanding the implementation and impact of three Off-Grid renewable energy systems in three different developing countries. Two of them are successfully implemented and the other is currently under implementation. The fully implemented Off-Grid systems selected for this paper are “Off-Grid Rural Electrification-Ladakh” in India and “Off grid Solar Power System for a rural village” in Malaysia. The system that is currently being implemented is the “Rural Renewable Energy Development Project” in Bhutan. These projects have been selected based on their significant contributions to rural electrification in their respective countries. 1.

Renewable Energy Sources

...Chapter 8: Renewable Energy Sources The Sustainability Revolution John C. Ayers "In a sense, the fossil fuels are a one-time gift that lifted us up from subsistence agriculture and should eventually lead us to a future based on renewable resources." Kenneth Deffeyes (2001) "I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that." — Thomas Edison, 1931 We cannot create or destroy energy. We can only capture it. The sun provides either directly or indirectly nearly all of the energy available to us. Plants capture solar energy directly through photosynthesis. Fossil fuels contain the energy of sunlight captured hundreds of millions of years ago. Photovoltaic (PV) cells also capture sunlight energy directly. Other energy sources capture the energy of sunlight indirectly. Heat from the sun powers the flowing air and water. We usually capture the kinetic energy of wind and water by using turbines that transfer the energy to an alternator, an electrical generator that produces alternating current. Geothermal energy is different in that it captures flowing heat energy produced by radioactive decay in the earth’s interior. In this chapter we will see that Wind, Water, and Sun (WWS) energy sources are sustainable because they are renewable, clean, safe, and nearly carbon-free. Although they have low energy densities, meaning that they require large areas of land or water to produce......

...1.8 Life Cycle Costing Purpose Life Cycle Costing (LCC) is an important economic analysis used in the selection of alternatives that impact both pending and future costs. It compares initial investment options and identifies the least cost alternatives for a twenty year period. As applied to building design energy conservation measures, the process is mandated by law and is defined in the Code of Federal Regulations (CFR), Title 10, Part 436, Subpart A: Program Rules of the Federal Energy Management Program. The A/E shall contact local utility companies to determine available demand-side management programs and nocost assistance provided by these companies to designers and owners. Applications Basic applications of LCC are addressed within the individual chapters herein and may be further defined within an A-E’s design programming scope requirements. In general, LCC is expected to support selection of all building systems that impact energy use: thermal envelope, passive solar features, fenestration, HVAC, domestic hot water, building automation and lighting. However, LCC can also be applied to building features or involve costs related to occupant productivity, system maintenance, environmental impact and any other issue that impacts costs over time. It is very important to recognize the significance of integrated building systems design in the overall e iciency of the design. Methodology There are many established guidelines and computerbased tools that e......

Construction of a Sun Tracker

...represented by the wind and solar energy ones as a supplementary energy resource. The solar based one is the more attractive because it is characterized by being free, incur no fuel cost, abundant, limits less, distributed all over the world, pollution free, and require little maintenance. Maximizing power output from a solar system is desirable to increase efficiency and in order to maximize power output from the solar panels, one need to keep the panels aligned with the sun. As such, a means of tracking the sun is required. Efficient collection of maximum solar irradiance (MSI) on a flat plate type photovoltaic solar panels or a cylindrical parabolic solar reflector requires adjustments of two parameters of the energy collecting surface namely the angle of Azimuth, and the angle of tilt, of the surface to be illuminated. As the elevation angle of the sun remains almost invariant in a month and varies little (latitude + 100) in a year, there is no need for automatic adjustment of the tilt angle. Everyday, the sun rises in the east, moves across the sky and sets in the west. If one could get a solar panel to turn and look at the sun all day hours, then it could receive the maximum amount of sunlight possible and convert it into the more useful energy (electricity). The current of the solar module is very sensitive to the Isolation of the sun. Small tilt in the solar module makes the current drop rapidly. It has been estimated that the yield from solar panels can be......
