    A Photovoltaic System

    Roy Said:Can a Photovoltaic System Eliminate My Electricity Bill?We Answered:We live in Northern California. Our system is 3 kW, and produces enough to keep up with our yearly electric usage. However, we have no air conditioning, pool, and our stove and heating are gas. The house is about 1800 square feet. The system cost $12k net to put in, 4 years ago, and I just priced out the cost today, which would be more like $6k net. If you have A/C in your house, the first thing to look at is super-insulating both your walls and attic, so you...

    Jennifer Said:Have any economists come on the news and inspired people on how to help boost the economy?We Answered:Peter Schiff. Most economists are employed by the government and have a vested interest in preaching to the masses that the government can create wealth by printing paper, which is what has caused the GFC in the first place. It is *production* and capital accumulation that boosts the economy. The government's recipe of spending, debt, taxes, inflation and war are a disaster. They only serve to take wealth from the productive classes and pay it to the parasitic political class, who think nothing...

    Buy Solar Cell

    Tina Said:where can i buy solar cell chips?We Answered:Radio Shack, Sargent-Welch, Fischer Scientific, Allied Electronics, etc. A solar cell is not technically a "chip" like integrated circuits. It is a chunk of silicon wafer with a layer of semiconductor material which absorbs photons from light and generate electrons. There is a grid of collection electrodes which lead to the common + and - points. The inefficiency of solar cells stems from the irony of adding enough smaller and smaller conductors to gather more electrons reduces the area available for the electron-producing semiconductos material.Clara Said:Where can I buy a...

    Lance Said:Looking to buy a solar panel that would run an outdoor frezzer.?We Answered:A typical 130 watt solar panel is about $700. My 15cu freezer draws 175 watt, and, runs about 20-30 minutes each hour. You would need a minium of three panels - five would be better - to make this work since solar panels do not work at night, dusk, dawn, work less on a cloudy day or when not directly pointed at the sun. And you always loose power going from panel to battery to inverter. You also need a solar charger ($200)...

    Jeanette Said:A super special power inverter.?We Answered:All grid tied inverters can work while the grid is down. The difference between a grid tied inverter and just an inverter is that the control circuitry can synchronize the frequency and phase to that of the grid before a relay connects the two. When the grid is down, the transfer switch simply disconnects the inverter and your house from the grid. When grid powered is restored, the circuitry waits for the phase to line up, connects the two and ensures that the frequency remains synced. In a power...

    Edgar Said:Disadavtages to photovoltaic?We Answered:So you left it until the day before to ask this question? And then you start a sentence with 'yeah'? Also, you mean 'my friend and I' not 'me and my friend'. Anyway, enough criticism: Photovoltaic solar energy isn't very efficient. Although they recently developed solar cells that absorb a very broad-band of frequencies including all of the optical frequencies, they still suffer from reflection and internal heating. Also, they produce DC electricity. As most homes run off AC electricity this needs to be converted and that costs even more energy....

    Photovoltaic Solar Panel

    Nicole Said:What kind of power resistor do I need?We Answered:A photovoltaic solar cell puts out a voltage, but to get power out of it, it has to deliver a current. Power = Voltage x Current. To get current you need a load, which is something that draws power when a voltage is across it. A resistor will do this. A light bulb will also do this. As you take more and more current from the solar cell, the voltage produced by the cell will be reduced. If you had a light bulb across the solar cell and added another bulb,...

    Power Solar Cells

    Clayton Said:How many solar cells to power a computer fan?We Answered:A typical computer fan, say 8cm diameter, uses only 150mA at 12Volt DC. So that amounts to only 1.8 Watt. A 12V 5 W solar panel should do nicely, even in indirect sunshine. But what do you do when it's dark? So you also need a battery to harness the charge during daylight, and consider the Ah (Ampere x hours) you need.Ray Said:How does solar cells and gas power stations create electricity?We Answered:The light photons knock an electron loose in the semi-conductor silicone wafer of the solar cell....

    Power Solar Panels

    Kathy Said:What is the power rating on Solar panels mean?We Answered:Hey JT, J3 is correct on the math, except that 12 volts is the, "nominal," voltage of the system. The problem here is that to charge a 12 volt battery usually requires at least a 15 volt power source. To accommodate this, panels are generally wired for 18 volts, allowing the charger controller or other wiring to use up a small amount, and still leave enough for the battery to charge on. A 7 watt panel that is wired for a 12 volt nominal system will likely...

    Purchase Solar Cells

    Helen Said:From where can I purchase solar cell of 500mA(approximate) ?We Answered:BEL can supply you solar cells. They come in big panels. The voltage produced varies with light intensity. When you load the voltage and hence current will drop. You may have to parallel many panels to get 550mAs. You should have a battery to act as a standby as solar cell alone will not be able to drive your car. The solar cell can act as a charger for your batteries. That is the practice.Pamela Said:find solar cells?We Answered:We use a company called Power Up to suppy our solar panels... maybe...

    Pv For Sale

    Virginia Said:Sale item question - Present Value?We Answered:That's because the Present Value formula is used for accounting purposes; whereas, you want to determine the current value of a sale item after a discount. In fact, "100 / 1.30" from the present value formula translates to: "The Present Value of $100 one year from now at an interest rate of 30%." Which is not the same as: "The current price of a $100 item after a 30% discount." Another way you can compute the price of a sale item after discount is: Final Price = Price * (1 - discount rate) For example, if...

    Pv Panels Solar

    Gladys Said:Positive grounding of a PV solar system?We Answered:There are two distinct advantages to grounding the positive leg of a photovoltaic solar system. They both relate to leakage to ground. This occurs primarily because of moisture. Electrolytic corrosion occurs at points of leakage. If the negative leg is grounded, the corrosion eats the material on the solar system side. Usually wires. If the positive leg is grounded, the corrosion occurs on the material of the accidental ground The second advantage is that the corrosion barrier becomes a diode. When the ;positive leg is intentionally grounded, the...

    Pv Power Inverters

    Lauren Said:Do pv inverters produce ac voltage?We Answered:PV inverters create voltage and current, yes. However, the above author is mistaken in that you cannot have current without a voltage. You can definitely have current without voltage. A superconductor is one example of this. By definition, a superconductor cannot have a voltage gradient across any two points in it, otherwise there would be resistance to currents. Also, if you are not working in a high-power industry, wires can be very well approximated as being able to carry currents without having a voltage across them (although this is not strictly true)Marlene Said:Active Power P...

If you have batteries (stand alone system) then you would have an inverter to suit the expected peak load. It seems unlikely that a 500KW system would be using batteries, but it is not impossible.. Solar panels can be connected to an...

    Pv Power Systems

    Lori Said:What is the difference between power (kW) and energy (kWh)? Why is this important when sizing a PV system? ?We Answered:kw is a measurement of power (1000 watts) kw/h is the measurement of energy used (1000 watts and hour or the equivalent of having ten 100 watt bulbs on one hour) When sizing a pv system you should do your best to cut back wasted energy and find out around how much energy you average a day so that you can get the proper size pv system. If you overestimate your usage you will buy too much system and cost will...

    Pv Powered Inverters

    Eric Said:Is anybody running 3 ph motors as on a CNC mill from inverted battery stored power? Any primers or how to's?We Answered:The first thing is to determine the power rating for the CNC mill and its other bits like air supply, lighting. This could be 12 to 40KW in my experience. That is between 100 and 333A for a single phase supply at 120V, half that for a 240V supply, so you tend to need three phase. There are inverters that convert single phase to three phase, but this load is tending towards too big for the typical home...

    Pv Solar Module

    Karen Said:Solar electric system help, please? DIY?We Answered:If you want to power the fans only when solar energy is produce, the solution is rather simple, the sum of the load current should be a bit less than the current the panel can provide. I believe a typical 80mm CPU fan draws 150ma, which is about 1.8W (I'd round that to 2W), and leave extra, so a 5 watt panel should run two fans easy. If you want to run the fans all the time, in addition for accounting for powering the fans needed when solar is present, you need to account solar...

This voltage?We Answered:In a simple system (say one without voltage regulation controls) that has *not* been connected to the grid, you very well might see varying voltage peaks. Once the output is connected to the grid, the output will only rise 1-3 volts above grid voltage because the grid appears to be a massive load. The PV system does not have enough power to drive the grid to a higher voltage. If you are interested in some numbers, let's say that your system connects to...

    Solar Cells Used

    Robin Said:can solar cells are used for mobiles for its charging?We Answered:Of course it's possible. But it isn't practical. Assume your mobile's battery is 3.7V at 800 mAh - that is 3 watt-hours. A largish mobile phone like an iPhone has a surface area of about 11 x 6 cm, 66 square cm. That is 0.0066 of a square meter. The brightest sunlight in the US (I'm talking about the southwest US in summer, for a few hours around noon) gives about 1000 watts of light power. Easy to remember - 1000 watts/square meter. You do not get that by...

    Solar Electricity Panels

    Robin Said:Do solar panels produce more electricity in stronger sunlight?We Answered:Sunlight "strength" is not a physical property. If by stronger sunlight, you mean the shortest distance between your solar panel and the sun over the course of a day, then yes. Photovoltaic cells can have multiple junctions that allow for varying wavelengths of light to penetrate the layers of the panel and generate a direct current. When the sun is directly above you, you will be exposed to as many wavelengths as are available to make your PV cell generate current. When the sun is setting, the...

    Solar Energy Panels

    Hector Said:Are solar panels for green energy worth getting?We Answered:Solar panels are warranted for 25 years. Generally, companies warranty for half the product's expected life span, so they expect 50 years from them. We can't tell for sure how long panels will last, because the first ones made are still working. If you have a solar system with battery backup, the batteries do have less than a 10 year lifespan. But 80% of solar installations are straight to the electric grid with no batteries. If you are looking for a good return on investment, look into solar water heating....

But there are also the clouds, which reduce insolation. So, in general, your area is good if there are not many clouds, typically. There are good solar radiation atlas around. They will...

    Solar Power Systems

    Jenny Said:How can i synclonize solar power with inverter?We Answered:There are 2 distinct situations, each one is using a different type of inverter 1. For homes connected to the grid the inverter is connected to the solar panel on the DC side and the DC voltage and DC current rating should match. The inverter AC side is connected to the home and to the grid (power lines entering the home). The inverter synchronizes to the grid frequency (60 Hz in the USA). In essence the home is fed from a combination of the inverter power and grid power. View this link...

    Solar Power Uk

    Eileen Said:Question about solar power, UK only please?We Answered:For hot water, you can use Thermomax (Wales). The best captors in my opinion. For electricity, solar panels are still expensive, but can be bought from Germany (+/-£300 for 80W). Not too good in UK, unless you set them up on a solar tracker. All in all, a very expensive business!. The other option is wind power if you live in a windy place. Cheaper, but complex to set-up.Shirley Said:Does Solar Power Have a Future in the UK?We Answered:Yes, It definitely has a future since the need for alternative fuels will rise...

    Solar Pv Batteries

    Sheila Said:When wiring 2 separate solar PV charge controllers is it in series or parallel to the Battery?We Answered:your question spells trouble you need to consult with the vendor for proper tuning unless you want to change the system voltage they would normally be in parallel however the controllers may not like that normally what is done is that one controller is set higher and charges most of the time the second panel kicks in when the voltage is somewhat low Guru...

There will be two wire outputs - one negative terminal and the other positive terminal. Four wire connection If you want more current from a solar cell, you can connect solar cells in parallel, i.e. Positive terminal of one panel to positive terminal of second panel and neagtive terminal of one panel to negative terminal of the other panel. This can be used if panels...

    Solar Pv Cost

    Lewis Said:Hi. What are salient differences over amorphous Solar PV and crystalline PV in terms of costs, benefits?We Answered:Crystalline PV is more efficient. Amorphous solar PV is cheaper. The reasons for the efficiency are reasonably technical physics to do with charge recombination and the likes. Amorphous solar is cheaper because you don't have to grow a massive, highly purified single crystal (which is VERY expensive), you can make it thinner because it has better absorption properties and it's cheaper to make a thin film....

    Solar Pv India

    Ernest Said:Calculate Solar Capacity?We Answered:Depends on your area's solar output. India's range is apparently 4 to 7 KW/H per m2 per day. If we used 5 hours as an example, then a 4kw system should give you (on average over the whole year) 20kw/h per day. There's also losses to take into account if you're using an inverter to convert the current from DC to AC, and also cabling losses if you have long cables in the system. So a 4kw system will probably not be able to do it. But 30 'units' (KW/Hs?) is a lot. Can't you make your...

    Solar Pv Inverter

    Jill Said:If I use a 3000 watt inverter, and a 800 cranking amps battery,what size solar pv would be required for charg?We Answered:It depends on a lot of factors. What is your actual average load? probably not 3000 watts. You will need this number. Let's assume 1000 watts. How many hours of sun a day do you get, average, in summer and winter? How many hours/days of sunless days do you expect the battery to supply power for. This is very important, as a large number of days here will make the number of batteries very large. The reason you need these...

Be sure to pay attention to the unit (1 amp is 1000 milliamps, so make sure to divide your "milliamp" reading by 1000) Then, to convert to watts you just...

    Solar Pv Panels

    Melvin Said:How do I repair a broken solar handheld toy? Sunshine Buddy stopped working:(?We Answered:You could try to measure the output of the PV panel to see if it is providing the proper voltage output to make the toy function. Not knowing how much power it requires to run your toy, you could substitute a battery to first check if the toy functions to determine if the PV panel is defective. See websites below. Finally, if the PV panel is found to be defective, you could externally wire a substitute PV panel to continue using or playing...

    Solar Pv Systems

    Anthony Said:Solar PV on houshold rooftops; why not more?We Answered:I believe a lot of people do understand about the real savings, I do. However, purchasing a system is not a real option for a lot of people. I'm a renter, so it's out of the question for me. My landlord COULD do it, but at this very moment, I would prefer double paned windows and insulation in the walls. That would lower my electric bill a GREAT deal. When my husband and I buy a house, we hope to install solar. Depending on where that is (in the country or...

    Solar Pv Training

    Jerome Said:what is Solar PV Training?We Answered:There are 2 types of "Solar", one is PV (Photovoltaic) meaning it can turn the sunlight or solar radiation (not the heat from the sun) into usable electricity. The other "solar" is used to heat water, here is where the heat from the sun warms water or air circulating thru a tube or pipe! So solar PV training would be electrical training, ie. electrician or electrical engineering. I hope this helps.Anne Said:Why Get Solar PV Training?We Answered:PV - or Photovoltaic training is an important aspect of solar powered energy resources training. This is because...

    Solar Roof Tiles

    Dean Said:If I installed fans on top of a roof to blow across the tiles, would it make the house cooler.?We Answered:No. That would just waste energy. The tiles do not get much "Cooling" from the breeze. We feel cooler with a breeze because of the evaporation of our sweat. The roof tiles just see moving air at about the same temperature. Much better to use a very small amount of power to ventilate the attic space when the house is hot. Most heat transfer is a function of the temperature difference, and amount of insulating value between the hotter...

    The Solar Company

    Regina Said:What is the best solar company to invest in, in the entire world?We Answered:It depends on your investment goals. If you are just playing for fun, and can afford to lose, make a bet on any individual company. You can find a list of somewhat established companies by seeing what goes into a solar ETF such as TAN. If you have a general belief that the solar market will succeed, but don't know which companies will survive a shakeout, invest in TAN directly.Tonya Said:What is a good acronym for a solar company?We Answered:S-Superb O-Outstanding L-Liberating A-Awesome R- Radiant IDK, LOL. :-)Geraldine Said:What's the...

    The Solar Energy

    John Said:How did the cycling of solar energy through the biosphere begin?We Answered:First, to be precise, nobody actually knows for sure. We do not even know exactly when life, as distinct from non-living chemical activity, began. Prior to life on earth, the elemental chemical composition of the earth was constant, same as now, but the molecular chemical composition was different. There was likely no free oxygen, the predominant gaseous materials likely being water vapor, methane, and ammonia. Once the average earth surface temperature dropped below the boiling point of water, life as we know it became...
