پاکستان توانائی کے مسائل میں شدیدطرح الجھا ہوا ہے۔ خدا کے فضل و کرم سے ہمارے پاس تقریباً تمام قدرتی وسائل موجود ہیں پھر کیا وجہ ہے کہ ہم پریشانیوں میں الجھے ہوئے ہیں۔ خدا نے انسان کو عقل دی ہے جس کو استعمال کرتے ہوئے وہ نہایت پیچیدہ مسائل کو حل کر سکتا ہے۔ پھر کیا وجہ ہے کہ ہم توانائی کے متبادل کا انتخاب نہیں کررہے؟ ہمارے ملک میں متبادل توانائی پالیسی ترتیب کیوں نہیں دی جا رہی؟
ہاں یہ درست ہے کہ پاکستان پانی، گیس اور تیل کی کمی کا شکار ہے اور ان تمام ذرائع سے بجلی کی ضروریات کو پورا نہیں کیا جا سکتا مگر ہم سورج کی کرنوں، ہوا اور دیگر ذرائع سے توانائی حاصل کر سکتے ہیں۔
ہمارا ملک دنیا کے اس خطے میں واقع ہے جہاں سورج کی کرنیں اوسطً نو سے دس گھنٹے پڑتی ہیں۔ ہم ان سورج کی کرنوں سے توانائی پیدا کر سکتے ہیں۔ سورج کے ذریعے حاصل کی جانے والی توانائی کو شمسی توانائی کہا جاتا ہے۔ شمسی توانائی خدا کا ایک انمول تحفہ ہے، اگرچہ شمسی توانائی پانی کی نسبت زیادہ طاقت ور نہیں مگر پھر بھی اس سے توانائی کا بڑا حصہ حاصل کیا جا سکتا ہے۔ اسپین کے علاقے نیورا جہاں توانائی کے روایتی ذرائع نہ ہونے کے باوجود بجلی کی ساٹھ سے ستر فی صد ضرورت کو شمسی توانائی سے پورا کیا جاتا ہے شمسی توانائی کے بہترین استعمال کی بہترین مثال ہے۔
وزارت بجلی وپانی کا یہ کہنا ہے کہ پاکستان میں شمسی توانائی سے انتیس لاکھ میگاواٹ بجلی پیدا کی جا سکتی ہے، شمسی توانائی کے استعمال پر زور کیوں نہیں دیا جا رہا۔ شمسی توانائی دیگر تمام ذرائع کی نسبت آلودگی سے پاک ہے۔ کوئلے ، گیس اور تھرمل سے حاصل ہونے والی توانائی سے گرین ہاﺅس گیسز کا اخراج ہوتا ہے جبکہ شمسی توانائی ایسی کوئی گیسز کا اخراج نہیں کرتی جو کہ ماحول کی خرابی کا باعث ہوں۔
لوڈشیڈنگ کے باعث زیادہ استعمال ہونے والے یو پی ایس سے دو سے چار گنا اضافی بجلی استعمال ہوتی ہے جس کی ادائیگی ہمیں بجلی کے اضافی بل کی صورت میں کرنی پڑتی ہے۔یوپی ایس کی نسبت شمسی پینل کو لگوانے سے اضافی بل کی ادائیگی سے بچا جا سکتا ہے ۔ شمسی پینل ایک دفعہ کا خرچا ہے اور اس کی مدت کم سے کم بیس سال ہے اس دوران دو سے چار سال بعد صرف انونٹر کو تبدیل کرنے کی ضرورت پڑتی ہے۔
ہمارے پڑوسی ملک بھارت نے توانائی کی ضروریات کے پیش نظر شمسی توانائی کے استعمال کو فروغ دیا ہے۔ دہلی کے نزدیک گوالی پہاڑی میں سورج سے بجلی کی توانائی حاصل کرنے کے لیے ایک بجلی گھر بنایا گیا ہے جہاں پیداوار اور تحقیقی کام کیے جا رہے ہیں۔ بھارت کے دیگر حصوں میںفوٹو وولٹالک سنٹرز قائم کیے جا چکے ہیں جو ایک کلوواٹ سے ڈھائی کلوواٹ تک بجلی پیدا کرتے ہیں۔ گھروں، کارخانوں، ہوٹلوں اور اسپتالوں میں پانی گرم کرنے کے لیے ایسے آلات لگے ہیں جوایک سو لیٹر سے لے کر سوا لاکھ لیٹر تک پانی گرم کر سکتے ہیں۔ بھارت شمسی توانائی سے ایک فیصد سے بھی کم بجلی پیدا کرتا ہے۔
توانائی کا ایک اور متبادل ہوا بھی ہے ۔ دنیا کے بیشتر ممالک ہوا سے توانائی حاصل کر رہے ہیں۔ ان میں امریکہ، جرمنی، فرانس، چائنہ، اٹلی، اسپین، پرتگال اور انڈیا شامل ہیں۔ ایک اندازے کے مطابق پاکستان میں ہوا سے پچاس ہزار میگا واٹ بجلی با آسانی پیدا کی جا سکتی ہے۔ پاکستان کے ساحلی علاقوں کا موسم ہواسے توانائی پیدا کرنے کے لئے بہترین ہے۔ ماہرین کا کہنا ہے کہ پاکستان کی ساحلی پٹی میں ہوا سے بجلی پیدا کرنے کے امکانات روشن ہیں۔
ہو اسے توانائی یعنی ونڈ انرجی سے توانائی کا حصول حکومتی توجہ کا منتظر ہے۔ ہوا کی کم از کم دو سے تین کلومیٹر فی گھنٹہ کی رفتار کو ونڈ انرجی کے لئے موزوں سمجھا جاتا ہے جو خوش قسمتی سے کراچی، ٹھٹھہ، کوئٹہ ، جیوانی، حیدرآباد، بلوچستان کی ساحلی پٹی، صوبہ سرحد کی چند شمالی وادیوں اور آزاد کشمیر کے علاقوں میں ہوا کے ذریعے تقریباً تین ہزار میگا واٹ بجلی پیدا کی جاسکتی ہے۔
اس وقت جرمنی ہواسے اٹھارہ ہزار میگا واٹ، اسپین آٹھ ہزار میگاواٹ ، امریکہ سات ہزار میگاواٹ جبکہ بھارت تیرہ ہزار سے زائد بجلی پیدا کررہا ہے۔ شمسی توانائی کی طرح ہوا یعنی ونڈ انرجی بھی ہر قسم کی آلودگی سے پاک ہے اور اس سے ماحول آلودہ نہیں ہوتا۔
میڈیا کی ایک رپورٹ کے مطابق ہوا سے چلنے والے ٹربائنوں کا دنیا کا سب سے بڑا پراجیکٹ برطانیہ میں مکمل ہوا ہے۔ رودبار انگلستان کے ساحلی علاقے کینٹ میں قائم کیے جانے والے تھانٹ ونڈ فارم میں ایک سو انتہائی طاقت ور ٹربائن لگائے گئے ہیں۔ ماہرین کا کہنا ہے کہ یہاں سے حاصل ہونے والی بجلی دولاکھ سے زیادہ گھروں کی توانائی کی ضروریات پوری کرنے کے لیے کافی ہو گی۔ اکثر ساحلی علاقوں میں زیادہ تر تیز ہوائیں چلتی رہتی ہیں جن کی مدد سے بجلی پیدا کرنے والے ٹربائن باآسانی چلائے جاسکتے ہیں۔ پاکستان کی ساحلی پٹی میں اس طرح کے منصوبوں کے لیے بڑی گنجائش موجود ہے جس سے لاکھوں گھروں کو توانائی فراہم کی جا سکتی ہے۔ لہٰذا ہمیں توانائی کے اس متبادل ذریعے سے بھر پور فائدہ اٹھانا چاہئے۔
یو ایس ایڈ کے تعاون سے پاکستان میں کئے گئے ایک سروے کے مطابق ملک میں ہوا سے تین لاکھ چھیالیس ہزار میگا واٹ بجلی پیدا کی جاسکتی ہے۔اس وقت پاکستان توانائی کے سخت بحران کا شکار ہے اور صنعتیں بند ہونے سے سینکڑوں مزدور روزگار سے محروم ہیں جبکہ ملک بھر میں پندرہ سے اٹھارہ گھنٹے کی لوڈشیڈنگ نے لوگوں کو ذہنی اذیت میں مبتلا کردیا ہے۔ توانائی کے متبادل ذرائع کو استعمال میں لاکر ہی توانائی کے بحران سے نجات دلائی جا سکتی ہے۔

Solar Cell

You've probably seen calculators that have Solar Cell calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, solar cells seem to work forever. You may have seen larger solar panels on emergency road signs or call boxes, on buoys, even in parking lots to power lights.

Although these larger solar panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems.

You have probably also been hearing about the "solar revolution" for the last 20 years the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately 1,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy into solar cells we could easily power our homes and offices for free.

In this article, we will examine solar cells to learn how they convert the sun's energy directly into electricity. In the process, you will learn why we are getting closer to using the solar energy on a daily basis, and why we still have more research to do before the process becomes cost effective.

Uses of Solar Energy

Solar Energy Uses

We have always used solar energy as far back as humans have existed on this planet. We know today, that there are multiple uses of solar energy. We use the solar energy every day in many different ways. When we hang laundry outside to dry in the sun, we are using the solar heat to do work, drying our clothes. Plants use the solar light to make food. Animals eat plants for food. And as we learned, decaying plants hundreds of millions of years ago produced the coal, oil and natural gas that we use today.

Solar Products

Pakistan Solar Power manufactures many Solar Products in it's china factory and sells them internationally as well, these are very highly tested and quality products having good reputation inside the market of Europe and Asia, we can provide these products any where in the country, these products are currently pre-developed and some standard usage but we can also produce demand-to-make solar items.

Solar energy systems in Pakistan

Nov 062008

Many friends have inquired about availability of solar electric systems in Pakistan. I tried to contact many companies, claiming to have such systems including Siemens Pakistan, they did respond to my emails but failed to give any further information.

Today there is a news item from APP about the offer from Highnoon Group to electrify one village. I just found their website and have gathered some information from there, which is being posted here. I shall continue my search about solar systems and update visiting friends. I have decided to create a separate category about energy in order to gather all the information under one category because energy is the main issue these days in Pakistan; we have to explore new ways to have cheaper energy sources.

Solar Electric

Solar electric panels are high- efficiency, low maintenance ways to turn sunshine into usable electricity right at the location of the power demand.

Solar electric panels, or photovoltaic (PV) panels, are mounted in an unshaded area facing south, southeast, or southwest for use in a home or business that is already supplied with utility power or a home or cabin that is located a distance from power lines.

About the Grid Tie
Solar electric panels which are used in a system that already has utility power is called a ‘grid tie.’ These systems use no batteries but co-exist with the current utility grid, providing the best of both worlds. Solar panels that are used on a home or cabin that does not already have utility power is called an off- grid application. These systems use batteries to store power for night use and cloudy days, providing an independent, stand- alone system.

High Noon Offers Flexibility
High Noon Solar is highly experienced with solar electric design and installation of both types of applications, grid tie and off grid. Follow the links below to learn more about the solar electric system that best fits your situation and needs.

Residential Solar Grid Tie

Solar Electricity for Your Residence

With the cost of electricity progressively escalating and with a climate crisis hovering near, there is no better time to make an investment in solar electric panels for your residence.

The Simple Solution
A solar electric grid tie is one of the simplest, low maintenance investments you can make in your home, as well as for your planet.

In addition to the practical benefits of solar, High Noon Solar installs the top of the line in solar panel technology: Sunpower. Sunpower panels make a solar system no longer look like a solar system. The panel’s black frame and lack of metal ‘leads’ create a final installed appearance that is integrated and stylish, not obtrusive and unsightly. There is no better time to take the first steps toward owning your own power.

Utilizing Solar Energy in Pakistan

In these days of escalating oil prices, it’s becoming extremely difficult for a common citizen to pay off monthly electricity bills. The bills keep soaring day by day and there seems to be no respite in foreseeable future. These bills can be reduced by resorting to other methods of generating electricity, solar being one of them.

This article dwells on the discussion regarding production of electricity through solar means and discusses a cost-effective strategy to achieve this end.

The photo above shows Solar Panels being used for water extraction in village Rarkou in Nagarparkar, Sindh

The use of solar energy for the generation of electricity is not something new. Most of the countries are doing it successfully for decades and their population benefiting through the use of this free resource. But, to most of the people, it may still look like a mystery. These days, this energy is being utilized to light our homes, run fans, provide power to our fridges and microwave ovens, assist in warming our homes and swimming pools, provide power to our gardens and street lights, run our TVs and computers, and extract water from the sub-soil for irrigation purposes.

Solar Energy: An Over View

As solar power does not make sense for all locations in the world. The initial cost of installing solar panels or other sources of solar energy is high, and that is not easy for most people to get around. No matter how much some people would like to get involved in the movement to independent energy, it is cost prohibitive.To achieve the highest level of efficiency, which is the entire point of going solar in the first place, you need the proper amount of roof space to support the panels your house may require. Not only how much space is available, but also the location of your home is also relevant to whether or not you can maintain solar energy. Some houses simply do not receive enough sunlight to produce substantial energy. This could mean that either your house is not positioned favorably in relation to a tree or other house.

Pakistan is most suitable for solar power:

As you can see, the cons of implementing solar power in your home are primarily cost and location related, but if those two items do not pose issues for you, the good news is…

If solar power is looked at through a long-term lens, you will eventually make back what you originally spent, and possibly start saving money on your investment

Let’s not forget that solar energy increases the value of your home too. Solar power is not subject supply and demand fluctuations in the way that gas is. Silicon, the primary component of solar panels, is also being more widely produced, therefore, less and less expensive with each passing year.

Solar power is independent, or semi-independent. This is great because you can supply your home with electricity during a power outage. Solar power can also be used in remote locations, places where conventional power can’t be reached. On a larger scale, solar power also reduces our need to rely on foreign sources for power.

And last, but certainly not least, it’s good for our planet! Solar energy is clean, renewable and sustainable. It does not fill our atmosphere with carbon dioxide, nitrogen oxide, mercury or any other pollutants. It is a free and unlimited source of power, unlike expensive and damaging fossil fuels.

Home made solar water heater

Who says Pepsi bottles are useless: Why not a solar hot water heater?

This Chinese farmer is getting hot shower water from this roof of Pepsi bottles and plastic tubing. This version of the story was seen on Ananova (sent in by reader Arnaud Betremieux). The account says “I invented this for my mother. I wanted her to shower comfortably,” says Ma Yanjun, of Qiqiao village, Shaanxi province.Ma’s invention features 66 Pepsi bottles attached to a board. The bottles are connected to each other [with plastic tubing] so that water flows through them.Sunlight heats the water as is passes slowly through the bottles before flowing into the bathroom as hot water, reports China Economy Network. Ma says it provides enough hot water for all three members of his family to have a shower every day.And more than 10 families in the village have already followed suit and installed their own versions of Ma’s invention.”

Lever force to produce energy.

Hello friends have you any idea how much Energy can be produced through lever force.
First of all I want to tell you about "lever" . Next post will be about producing Energy.
In physics, a lever is a rigid object that is used with an appropriate fulcrum or pivot point to multiply the mechanical force that can be applied to another object. This is also termed mechanical advantage, and is one example of the principle of moments. The principle of leverage can also be derived using Newton's laws of motion and modern statics.
1 Early studies
The earliest remaining writings regarding levers are provided by Archimedes ("Give me a place to stand, and I can move the Earth.", a remark of Archimedes quoted by Pappus of Alexandria) who formally stated the correct mathematical principle of levers.

2 Force and levers
The force applied (at end points of the lever) is proportional to the ratio of the length of the lever arm measured between the fulcrum and application point of the force applied at each end of the lever. Mathematically, this is expressed by M = Fd.

3 The three classes of levers
There are three classes of levers representing variations in the location of the fulcrum and the input and output forces.

3.1 First-class levers



Examples:

Seesaw (also known as a teeter-totter)
Crowbar
Pliers (double lever)
Scissors (double lever)
3.2 Second-class levers



Examples:

Wheelbarrow
Nutcracker (double lever)
3.3 Third-class levers



Examples:

Human arm
TongsTongs are gripping and lifting instruments, of which there are many forms adapted to their specific use. Some are merely large pincers or nippers, but the greatest number fall into three classes: the first, as in the common fire-tongs, used for picking up ( double lever )

Solar Energy storage.

In this Article we will learn how to make storage energy produced by solar system.

Solar Two's thermal storage system generated electricity during cloudy weather and at night.

Solar energy is not available at night, and energy storage is an important issue because modern energy systems usually assume continuous availability of energy.

Thermal mass systems can store solar energy in the form of heat at domestically useful temperatures for daily or seasonal durations. Thermal storage systems generally use readily available materials with high specific heat capacities such as water, earth and stone. Well-designed systems can lower peak demand, shift time-of-use to off-peak hours and reduce overall heating and cooling requirements

Phase change materials such as paraffin wax and Glauber's salt are another thermal storage media. These materials are inexpensive, readily available, and can deliver domestically useful temperatures (approximately 64 °C). The "Dover House" (in Dover, Massachusetts) was the first to use a Glauber's salt heating system, in 1948.

Solar energy can be stored at high temperatures using molten salts. Salts are an effective storage medium because they are low-cost, have a high specific heat capacity and can deliver heat at temperatures compatible with conventional power systems. The Solar Two used this method of energy storage, allowing it to store 1.44 TJ in its 68 m³ storage tank with an annual storage efficiency of about 99%.

Off-grid PV systems have traditionally used rechargeable batteries to store excess electricity. With grid-tied systems, excess electricity can be sent to the transmission grid. Net metering programs give these systems a credit for the electricity they deliver to the grid. This credit offsets electricity provided from the grid when the system cannot meet demand, effectively using the grid as a storage mechanism.

Pumped-storage hydroelectricity stores energy in the form of water pumped when energy is available from a lower elevation reservoir to a higher elevation one. The energy is recovered when demand is high by releasing the water to run through a hydroelectric power generator.

Solar Energy

This article is about all uses of solar energy. For generation of electricity using solar energy, see Solar power.

Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used.

Solar power provides electrical generation by means of heat engines or photovoltaics. Once converted, its uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes.

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute sunlight. Active solar techniques include the use of photovoltaic panels and solar thermal collectors (with electrical or mechanical equipment) to convert sunlight into useful outputs. 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.

Energy from the Sun

About half the incoming solar energy reaches the Earth's surface.

The Earth receives 174 petawatts (PW) of incoming solar radiation (insulation) at the upper atmosphere.Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.

Earth's land surface, oceans and atmosphere absorb solar radiation, and this raises their temperature. Warm air containing evaporated water from the oceans rises, causing atmospheric circulation or convection. When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle. The latent heat of water condensation amplifies convection, producing atmospheric phenomena such as wind, cyclones and anti-cyclones. Sunlight absorbed by the oceans and land masses keeps the surface at an average temperature of 14 °C By photosynthesis green plants convert solar energy into chemical energy, which produces food, wood and the biomass from which fossil fuels are derived.

and land masses is approximately 3,850,000 exajoules (EJ) per year. In 2002, this was more energy in one hour than the world used in one year. Photosynthesis captures approximately 3,000 EJ per year in biomass. The amount of solar energy reaching the surface of the planet is so vast that in one year it is about twice as much as will ever be obtained from all of the Earth's non-renewable resources of coal, oil, natural gas, and mined uranium combined.

From the table of resources it would appear that solar, wind or biomass would be sufficient to supply all of our energy needs, however, the increased use of biomass has had a negative effect on global warming and dramatically increased food prices by diverting forests and crops into biofuel production. As intermitten resources, solar and wind raise other issues.

Darmstadt University of Technology in Germany won the 2007 Solar Decathlon in Washington, D.C. with this passive house designed specifically for the humid and hot subtropical climate.

Sunlight has influenced building design since the beginning of architectural history. Advanced solar architecture and urban planning methods were first employed by the Greeks and Chinese, who oriented their buildings toward the south to provide light and warmth.

The common features of passive solar architecture are orientation relative to the Sun, compact proportion (a low surface area to volume ratio), selective shading (overhangs) and thermal mass. When these features are tailored to the local climate and environment they can produce well-lit spaces that stay in a comfortable temperature range. Socrates' Megaron House is a classic example of passive solar design. The most recent approaches to solar design use computer modeling tying together solar lighting, heating and ventilation systems in an integrated solar design package. Active solar equipment such as pumps, fans and switchable windows can complement passive design and improve system performance.

Urban heat islands (UHI) are metropolitan areas with higher temperatures than that of the surrounding environment. The higher temperatures are a result of increased absorption of the Solar light by urban materials such as asphalt and concrete, which have lower albedos and higher heat capacities than those in the natural environment. A straightforward method of counteracting the UHI effect is to paint buildings and roads white and plant trees. Using these methods, a hypothetical "cool communities" program in Los Angeles has projected that urban temperatures could be reduced by approximately 3 °C at an estimated cost of US$1 billion, giving estimated total annual benefits of US$530 million from reduced air-conditioning costs and healthcare savings.
