All About Solar Panels

 

Solar power panels are the lifeblood of any solar energy plan, whether you want to build your own solar panel to power a few lights, or you intend on constructing an entire solar panel house. They are the first step in the collection and harnessing of solar energy. Without them, no solar project, not even making a small solar panel can get underway. But exactly how do solar panel systems work?

Regardless of what solar panel project you you jump into a homemade solar panel and a store-bought solar energy panel are very similar. Let’s look at how they actually take sunlight and create energy.

Home solar panel systems and huge commercial solar panel systems work the same way. Photovoltaic (transforming light into energy) cells are arranged on a thin film solar panel . This thin sheeting is then mounted onto some type of flat rectangular frame, and angled to face the sun. These solar panels collect heat from the sun's rays. This heat is transferred to common household electricity by a solar inverter.

The electricity then usually runs through a charge controller before being stored in batteries for later use. This is why solar panel efficiency runs so high. There are very few steps involved, so very little energy is lost in this process. Unlike electricity, which is most commonly created by burning coal and storing energy at some distant power plant, solar energy is clean and localized. You own your own solar power plant.

Sіmрlісіtу and рrіdе are also some of the reasons ѕо mаnу hоmеоwnеrѕ орt to buіld thеіr оwn " homemade ѕоlаr panel ". It іѕ fun, educational for the whоlе fаmіlу, and саn bе started оn аnу budgеt. Thе ѕіzе of ѕоlаr раnеlѕ can bе tаіlоrеd fit to уоur ѕресіfіс nееdѕ аnd ѕрасе lіmіtаtіоnѕ. And уоu can start ѕmаll аnd rаmр up production аѕ уоur budgеt аllоwѕ. Evеn thоugh making a hоmе ѕоlаr power раnеl іѕ relatively easy, the lоw соѕt of "ready-to-go" аll іn оnе hоmе solar panel systems has most соnѕumеrѕ рurсhаѕіng rather than learning thе рrосеѕѕеѕ of solar раnеl соnѕtruсtіоn .

Capstone Turbine – Innovation in Clean and Green Energy



So when we look at the world, energy consumption is increasing every year. But most importantly, that energy needs to be clean. We have 1. 3 billion people without powerworldwide. Plus you have the issue of smog, emissionsenvironmental issues. It's not sustainable to keep growing the way theplanet iswithout having more energy efficiency, clean energy, low emissions,and zero emission technologies. And when you think of clean energy, Capstone is one of theinnovative leadersbecause we generate power at the source with ultra low emissions,extremely high reliability, and a cost-effective manner. Innovation in anysector is a challenge and energy is no different. Trying to develop new cutting-edge technologies with higher efficiency andlower emissions,you can't sacrifice reliability or quality. Capstone's microturbine technology is veryclean, very green. It has several other unique features, including an air bearing technology,which means we have no oil, no antifreeze, one moving part. Really, power electronics are the key to our solution. This allows a customer to focus on their corebusinessand spend less time doing maintenance on the microturbine. Capstone's microturbines serve several energy needsreally depending on the end-user. Whether it's prime power, peak shaving, backup power. All of our customers will typically use our product at least 50 percent of the time. We also solve energy needs when it comes to energy efficiencyand thermal use of the products. Taking steam, hot water,or even chilled water from the absorption chiller off the back of our exhaust. Capstone has shipped over six thousand microturbines worldwide, and has thousands ofinstallationsvirtually in almost every corner of the globe. Whether you're a plastics company here inCaliforniaor you're a food processor in Austria, you can use our technology as part of your keymanufacturing process. So here in California, the plastic company is actually using our exhaust to melt theplasticas part of theirmanufacturing process. Or in the food application in Austria, they're using itto sterilize bottles. So not only are we providing clean energy,reliable energy, we are seeing energy efficiency rates as high as90 percent, and are critical to their manufacturing process with the heat coming off the machine. Oil and gas is one of the key areas for Capstone's innovation. Whether it's in the U. S. in oil and gas operations, in shale gas operations, orinternationalin both offshore and onshore platforms. Capstone has been instrumental in helping customerslike Shell,Pemex, Petronas, Petrobras, or Origin Energy down in Australia, not only provide theenergy they need to get their product tomarket, but do it in an environmentally safe and friendly way. Capstone has been an innovator in the hybrid vehiclespace for a long time. The company is actually founded on a hybrid vehicle platform. Today, most of our applications are transit buses. These buses are electric vehicleswith congenitive brakes, and the microturbine sits in the back of the bus. And when the batteries get depleted - about 30 percent state of charge - the microturbinefires up and charges the batteries. And with a small company called Wright Speed, they're taking medium-duty trucks fordeliveryand package applications, and re-powering them with Capstone technologies. So these are hybrid vehicles, electric vehicles with congenitive brakes,using the Capstone microturbine as a range extender. So getting the vehicle so it can run twenty hours a day without having to stop and refuel. As we look for new applications for our product, Marine isone that fits our technology very well. Energy reliability is extremely critical. Emissions are becoming more and moreimportant worldwide. And most importantly, we are quiet with almost no vibration, which is essential in marine applications. The future for Capstone is very bright. In the last several years we have grown the business 20 to 30 percent a year with ourinnovative technology. Getting new customers new applications worldwide. But we continue to innovate our technologies. We have a 250 kilowatt,and 370 kilowatt version, we are currently developing with help from the Departmentof Energy. What's key about these technologies: they are higher efficiency, which is lower costper kilowatt,and allow us to penetrate more markets and have faster payback for our customers. So wherever you are in the world, whatever application you're in, whatever country you are in,Capstone is dedicated, through its reliable technology, to give yougreen, clean, low emission solutions that are both environmentally friendly,and economically friendly.

Greening our grid through renewable energy purchases



Ever think about how much energy it takes to search forsomething on Google?Our engineers spend a lot of time thinking about it andworking hard to make our operations asefficient as possible. This means when you search on Google or use one of our otherproducts or services, you don't use much energy at all. We've always optimized our data centers for efficiency,designing them to sip rather than gulp energy. For the energy we do need to power our products andservices, we are finding ways to use andpurchase clean energy. One of the ways we buy clean power is through powerpurchase agreements. PPAs are contracts to buy energy from specificfacilities that supply energy to a regional power grip. We engage in PPAs specifically for renewable energy sourceslike wind farms. Why not just build clean energy sources right on ourdata centers?The places with the best clean power potential are generallynot the same places where a data center can mostefficiently and reliably serve its users. And while our data centers operate 24/7, most renewableenergy sources don't yet. Google seeks out PPAs that lead to new renewable energysources being added to the grid over time. With PPAs, we aim to encourage the creation of additionalfacilities. So we enter into long-term, large scale contracts thatenable clean energy providers to get the financing they needto build new projects. At Google we have a strong interest in buying cleanenergy now and ensuring that we all have clean reliablesources of energy into the future. It's our hope that purchases like these help support themarket and drive down the cost of clean power, enablingrenewable energy projects to multiply.

UTS Science: Green energy



Facilitator: Professor, thank you so much for joining us today. First of all, tell usa little bit about the zinc oxide project. Professor: The zinc oxide project is one where we're looking at improving the efficiencyof the light emission properties of that material. This follows on from work that we've previouslydone on material known as gallium nitride. That work started 10years ago and now hasgone completely through from having an idea about how to use this material as efficientlight-emitting material, all the way through now so it's a commercial product. This issomething that you'll see that's been implemented in a whole range of applications. It's sortof a silent revolution. The standard incandescent bulb that's been around for the past hundredyears will become a thing of the past in the next 10 years or so. Facilitator: Okay, so just explain to me a little bit more about why it is so important. Professor: Well in terms of lighting, and this is known as solid-state lighting, sothis is a device known as a diode and a diode consists of a positive and negative or positiveand negative areas. With this material, because of these positive and negative areas, it setsup a little voltage barrier and this voltage barrier, if we apply a voltage to it, it canovercome the electrons, can overcome this barrier and that interaction will producelight. Now the advantage is it does this without producing any heat, so it's a very efficientprocess compared with, say, an incandescent bulb where 90 per cent of the energy that'sused is lost as heat rather than light. So it's a very low power for a very high brightness. Facilitator: So how, exactly, would this be used in people's everyday lives?Professor: Well it's already, now, these light-emitting diode traffic lights have proliferated aroundthe city already. If you go to any traffic lights now you'll basically see that insteadof one bulb it's actually comprised of something like 140 LEDs. Now the advantage with this,even though there's 140 of these, that because of their low power consumption that lightassembly actually uses one-third less power than a conventional incandescent bulb. Even,for example, these torches or flashlights that we have here, you can see that the incandescentbulbs have been replaced with the LED devices here. The advantage here is this bulb lastsfor 10years, so it has a very long lifetime and this is the same sort of technology thatwill be slowly introduced into domestic lighting. Actually lighting consumes something of theorder of 20 per cent of the total power worldwide. So if we can introduce solid-state lightingwhere we're actually using at least a half, you can see immediately that we have a 10per cent drop in our power usage which translates to a 10 per cent drop in the production ofgreenhouse gases. Facilitator: How does this apply with your research then?Professor: Well with our work, we work at a very fundamental level, understanding howwe can improve the efficiency of this material by growing this material with better quality. This material is all manmade material, so it's grown atom by atom, layer by layer. Aspart of this process, this process is being continuously refined to make better and betterquality materials and so we study the light emission from areas that are a millionth ofa millimetre to get a complete understanding of the mechanisms that are involved in producingthe light emission. Facilitator: I imagine that means you have some pretty spectacular machinery. Professor: Yes, like the one behind me here. This enables us to accelerate electrons tovery high speed and inject them into one of these materials, this new advanced materials,into this very small volume and then study how the light is emitted by the various attachmentsthat are sitting on the microscope behind me. Facilitator: Okay, so let's put that in everyday terms. How long before we see results outsidethe lab?Professor: Well, as I said, in terms of the gallium nitride technology that we've beenworking on for 10 years, that's already there. That's out there. These are now engineeringissues to make the product more cost efficient. What we're now working on is a material knownas zinc oxide. Zinc oxide has excellent properties, in some sense much better properties thangallium nitride and this is sort of the thrust of our research is trying to understand theoptical electrical properties of zinc oxide. Facilitator: Can you give me a timeframe, a ballpark timeframe?Professor: Well we're not the only group working on this. There's a lot of groups around theworld that are working on this problem and as this technology improves and we can producemore efficient bulbs that use less power and emit more light and also as the scale of productionincreases, the cost of these will continue to fall. It's very possible that in the next,well certainly in the next 20 years, that there'll be no incandescent sources in useat all. Facilitator: Professor, thank you so much for your time and taking the time to explainsome very complex ideas. Professor: My pleasure. Facilitator: Best of luck with your research. Professor: Thank you very much.

yes donna is not a pickup have taken
this course
only for one reason we have a deficiency
electricity
we have lotsa demand like electricity so
if we can make this rechargeable solar
energy system successful
it will bring great benefits to my
villagers and my country
allied
Miller for yasmin is one of several
young women in this class of forty
students
although most of the trainees are man
gender is no obstacle to this line of
work
or to her Hamid anymore I think nowadays
there is no difference when it comes to
men and women in the workplace
but to prove it are trying to be better
than the boys
the head teacher is also bullish on the
future prospects for this kind of
specialized work
I think job just post pics the bigger
a day by day mean is in our country
%uh I think after sometimes
it will be and decided by the by a Roman
them from system must be
in the or a home back in the capital
Dhaka
the government is intently following the
success of the solar home programs
and is promoting further expansion at
the concept to be jobs totally new for
us what that is and we need
specially I history it
be be support people loss
their viewing us cheney species

Australia we are working very closely
with the government
young players organization well kiss
organization
and some other key partner
to head Muzzin people
by providing skins so that they can
really get access
to solar pan
I think from independent perspective it
is a huge opportunity
that to delete this solar energy and
did and that could create green jobs
in mind that this ninja abilities the
workers so
with the two billion supports it to
bring the solar system
a in the bill is this where that is both
electricity from the
