Importance of solar panels

With the earth's natural resources dwindling quickly we were on the verge of running out of power. Electricity bills are rising day in and day out. In such a scenario, finding alternative sources of energy had become mandatory. Focus shifted to using renewable and inexhaustible sources to fulfill the energy needs. Solar energy emerged as a potential option. Other than saving the nation’s resources, solar energy has benefitted its users at the basic grass root level. It has now been touted as the major power source worldwide.

But the key element is each is to harness the power of the sunlight and generate electricity.

Types of solar panels

1. Monocrystalline Silicon: Out of all the currently available panels, this one is the most energy efficient. This is because of their high silicon content. They are expensive but you don’t need many of them, making it ideal for rooftops.
2. Polycrystalline Silicon: They are really inexpensive with low silicon content. The efficiency is very low. The overall construction design is so good that it often makes up for the efficiency loss. Yet, they are found in large solar farms only with large areas of land available.
3. Building Integrated Photovoltaic (BIPVs): They fit in perfectly with your roof tiles. They are very costly and the efficiency is way lower than conventional PVs.
4. Solar Thermal Panels: This has got more to do with heating water for your homes and swimming pools rather than generating electricity. Some systems provide heat and air conditioning.

How to choose a solar …show more content…
Get multiple quotes from different installers to know that you're getting the best deal.
• If you find the system too expensive, consider solar leasing and power purchasing agreements.
• Check the warranty periods. Installing a new solar system can be heavy for the pocket. Go in for systems and installers who give a longer warranty period.

Cost
In India, the average capital cost for solar panel systems is INR 691 lakhs/MW. The actual cost would depend on site location, components selected and the installer hired. Subsidies of up to 15% are provided through Solar Energy Corporation of India (SECI) for systems of sizes 100-500kWp.
The cost varies from country to country. In India, some of the best installers providing solar panel systems include Tata BP Solar India Ltd., Bharat Heavy Electricals Ltd. and HHV Solar Technologies Ltd. Etc.

Capacity required
Until and unless, you are planning to store surplus energy through batteries, it is important that you carefully estimate your energy needs. To get a system that pays for itself, you need a system that is just sufficient for your requirements. Assessing previous year’s electricity bills can easily do

...SOLAR ENERGY INTRODUCTION Without the sun, living life on earth is indeed impossible. Sun as we known is a ball of fire that gives us light and heat. The energy that we receive from the sun is called as the solar energy. With the help of this energy serious problems regarding energy that is needed everyday can be solved. Solar energy means capturing the rays of the sun and storing and its heat. This heat can be converted with the help of solar panels into heat or electrical energy. When we talk about solar energy, there are two kinds of solar energy namely, thermal energy and electrical energy. Thermal energy is something which we can find everywhere and is totally free of cost. It helps us ding our daily chores like dries things such vegetables, clothes, heats water, and many other things. Water can basically be heated in two ways i.e. actively and passively. In active method, when a heating element inside the solar hot water system heats the water during hot season. In the passive method the water is pre heated and flows through a cold inlet that of a conventional electric geezer. Talking about electric energy, the power of the sun is used to produce electricity with the help of solar cells. It can be used through a solar home system that helps in conducting electricity where there is no power supply. Apart from that it can be used a system where the electricity supplying utility is connected to the property and lastly it can be used as a backup system where...

Proposal on Impact of Solar Panel

...IMPACT OF SOLAR PANEL IN LIVELIHOOD IN SOME SELECTED (MD. IBRAHIM KHOLILULLAH, DEPT OF AG.FINANCE, BAU MOB: 01718996557) AREAS OF BOGRA DISTRICT Introduction Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity. Electricity is the prime mover for the advancement of all economic and industrial activities. About 59% of total population live in rural and isolated areas and most of them have no electricity access. This scenario is more acute in the rural and isolated areas in Bangladesh where only about 25% have electricity access ( Energy Bangla, January, 2014 ). Bangladesh is a semi-tropical region lying in northeastern part of South Asia gets abundant sunlight year round. The average bright sunshine duration in Bangladesh in the dry season is about 7.6 hours a day, and in the monsoon season is about 4.7 hours, Solar energy can be harnessed. So, solar panel technology is advised. A total of 3,00,000 solar panels had been installed in more than 40,000 villages of 456 upazilas of all districts of Bangladesh. Daily on average 44 MW electricity is being produced by these solar panels.( Momotaz and Karim,2012).Now a days solar panel is applied in different aspects such as solar based recharging station ,solar cooking etc. It presents an attractive alternative to conventional electricity such as no monthly bills, no fuel cost, little repair and maintenance costs, easy to install any where etc. The solar panel technology is very...

Estimation of Solar Energy for Street Lights in Vit

...ESTIMATION OF SOLAR ENERGY FOR STREET LIGHTS IN VIT ABSTRACT A solar lighting system which can make a 18x3 w lamp glow continuously for about (7) hours if the battery is fully charged has been constructed. Here, solar energy is collected with the aid of a solar panel and thus, a battery is charged during day time with the help of a simple charging circuit. During night time, this stored energy is used to light. The device can be used for small-scale lighting applications in remote areas that are far away from the power grid. The system has a panel to collect the sun’s energy, a battery to store that energy and a light source to use the energy. The system operates like a bank account. Withdrawals from the battery to power the light source must be compensated for by commensurate deposits of energy form the solar panels. INTRODUCTION Electricity is becoming costly every day; so many people are getting interested in using solar energy to fulfil their electricity needs. Power cuts and dependency on Generators is making people look for better sources. Solar Photo Voltaic panels provide a very good alternative way to fulfil their demand. Ministry of New and Renewable Energy (MNRE), Government of India is also promoting solar PV systems under the Jawaharlal Nehru National Solar Mission (JNNSM) in our country. They also provide subsidise solar panels under this scheme. There are so many people, interested in buying solar panels in India so we thought of doing a research on price...

Solar Flares

...2004 SOLAR FLARE CYCLES G. MARIª1, M. D. POPESCU1, 2 1Astronomical Institute of the Romanian Academy Str. Cutitul de Argint nr. 5, RO-752121, Bucharest, Romania gmaris@aira.astro.ro 2 Armagh Observatory College Hill, Armagh, BT61 9DG, N. Ireland mdp@star.arm.ac.uk (Received May 30, 2003) Abstract. We present a review of different solar flare periodicity intervals. Our analysis includes a statistical investigation of flare occurrence and N hemispheric distribution over the last three 11-yr -S solar cycles (SCs 21-23, correspondin g to the period 1976-2001). Moreover, we try to estimate if there is any connection between the flare activity and the strength of solar cycles. For that purpose, we studied not only the number of flares occurring monthly and annually, but we also used two indices that estimate the energy emitted by flares registered in the optical Hα line, as well as in the soft X -ray 1-8 Å band. The strange behaviour of SC 22 descending phase, with short but intense increments in flare activity, having a high degree of N-S asymmetry, could be the cause of the "abnormal" appearance of SC 23. The new magnetic dipole begins to lose part of its energy even during the descending phase of SC 22, so that the activity of SC 23 proves to be below the predicted values. Key words: Sun − solar flares – solar activity cycles − N-S asymmetry. INTRODUCTION Solar flares are wonderfully complex phenomena, seen as sudden and intense increases in brightness on the solar disk...

Hello Motto

...Title: SOLAR ENERGY: “SUNLIGHT into USEFUL ELECTRICITY” >Introduction< In today's climate of growing energy needs and increasing environmental concern, alternatives to the use of non-renewable and polluting fossil fuels have to be investigated. One such alternative is solar energy. Solar energy is quite simply the energy produced directly by the sun and collected elsewhere, normally the Earth. The sun creates its energy through a thermonuclear process that converts about 650,000,000 tons of hydrogen to helium every second. The process creates heat and electromagnetic radiation. The heat remains in the sun and is instrumental in maintaining the thermonuclear reaction. The electromagnetic radiation (including visible light, infra-red light, and ultra-violet radiation) streams out into space in all directions. Only a very small fraction of the total radiation produced reaches the Earth. The radiation that does reach the Earth is the indirect source of nearly every type of energy used today. The exceptions are geothermal energy, and nuclear fission and fusion. Even fossil fuels owe their origins to the sun; they were once living plants and animals whose life was dependent upon the sun. The sun is an inexhaustible source of energy. Solar energy is radiant energy from the sun caused by nuclear fusion in the sun’s core. The sun’s radiant energy reaches the earth in rays of sunlight. Solar energy in the form of heat and light sustains life on earth. Solar energy can...

Risky Behaviour

...Solar energy, radiant light and heat from the sun, is harnessed using a range of ever-evolving technologies such as solar heating, solar photovoltaics, solar thermal electricity, solar architecture and artificial photosynthesis.[1][2] Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries’ energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating climate change, and keep fossil fuel prices lower than otherwise. These advantages are global. Hence the additional costs of the incentives for early deployment should be considered learning investments; they must be wisely spent and need to be widely shared" The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere.[3] Approximately 30% is reflected back to space while the...

...Power of the Sun

...emulate this formula by harnessing the sun’s power to supply the earth with a clean, sustainable energy source akin to how nature enables an entire kingdom of organisms to do this for themselves. Solar panels, which are essentially a large collection of Photovoltaic (PV) cells, are manufactured to become excited with a certain amount of sunlight, breaking off electrons and either redirecting or collecting these channels of currents into usable circuits or storage units like batteries (Anderson, 2012). Both are similar in their initial design of creating energy out of sunlight, and both do not directly give off any harmful byproducts. Although it has been argued that the manufacture of PV cells and subsequent solar panels is hardly achieved through environmentally-friendly means (and certainly not with green parts), the benefits of the clean and sustainable energy produced far outweighs this temporary blemish in the overall process (Anderson, 2012). On a final note to the similarities between these two systems, both have an enormous constant source of energy (sunlight) that is transferred into usable energy for either the plants or humans utilizing it. Since the first law of thermodynamics clearly states that energy cannot actually be created or destroyed (Farabee, 2001), both systems have to convert light energy into otherwise usable energy, and the way in which they do...

Automated Sun Tracker

...CHAPTER-1 INTRODUCTION 1.1 INTRODUCTION TO SOLAR ENERGY Fig. 1.1(a) Block Diagram of Photovoltaic System Renewable energy is rapidly gaining importance as an energy resource as fossil fuel prices fluctuate. At the educational level, it is therefore critical for engineering and technology students to have an understanding and appreciation of the technologies associated with renewable energy. One of the most popular renewable energy sources is solar energy. Many researches were conducted to develop some methods to increase the efficiency of Photo Voltaic systems (solar panels). One such method is to employ a solar panel tracking system. This project deals with a microcontroller based solar panel is always able to maintain a perpendicular profile to the sun’s rays. Development of solar panel tracking systems has been ongoing for several years now. As the sun moves across the sky during the day, it is advantageous to have the solar panels track the location of the sun, such that the panels are always perpendicular to the solar energy radiated by the sun. This will tend to maximize the amount of power absorbed by the PV systems. It has been estimated that the use of a tracking system, over a fixed system, can increase the power output by 30%-60%. The increase is significant enough to make tracking a viable preposition despite of the enhancement in system cost. It is possible to align the tracking heliostat normal to sun using electronic...
