Q:How many Solar Panels do I need?
Everyday I use ,280 kWh 280 kW-hour / 24 hours = 470 kW WOW, that is a very high power level, most homes use an average of .2 kW. My guess is that you mean you use 280 kW-hour in a year, which comes to an average power of .3 kW, typical. Assuming you get, worse case, 6 hours of sun per day, for the first case, 470 kW, each solar panel generates the equivalent of 250 x6/24 = 60 watts, so you would need 470k/60 = 8000 panels For the second case, .3 kw or 300 watts, divided by 60 that is about 20 panels. Depending on where you live, you could need as much as twice that number. Plus you need charge controller, lots of expensive batteries, and an inverter. The big problem is periods of no sun. If you demand continuous power, and you have a period of, say, 24 hours with no sun because of storms, etc, then the number of batteries increases to the hundreds.
Q:Do you know that China is the largest producer of solar panels in the world?
I know for a fact that -China has a lot of Nuclear Bombs pointing at the US--- paid for by Wal-Mart
Q:Solar Panel load resistors?
Photovoltaic cells have a load curve that gives the power conversion based on the current drawn. This makes it harder to calculate. For instance, at infinite resistance, the solar cell will have a peak voltage that produces no power (P=I*V=V^2/r). At short circuit, the voltage collapses to essentially nothing and so the power is almost nothing. There is an optimal load (sweet spot) where the resistance applied will draw the most power out of the cell while not overloading it. This measure is either given by the manufacturer or found experimentally. Upon taking a lit panel that has no load and applying a 00 ohm resistance, the voltage will drop. By how much is entirely dependent on the array layout and specific cell characteristics. As the resistance drops from the optimal load point, the voltage collapses fairly sharply. As the resistance increases from the optimal load point, the voltage will rise more at first and then level off to the peak or no-load voltage.
Q:Why are solar panels placed on the roof of houses?
The roof is the most popular location for panels, I'd imagine because: ) The space is not otherwise being used. Panels in the yard would take up play space, or shade the garden or lawn. 2) The roof is usually more free from shadows because it's high up. Something low to the ground could more easily be shaded by trees, fences, or nearby buildings. 3) The roof often has a built-in tilt that is more ideal for panels. Take a good look at your roof, especially if there is a south-facing side. The roof could be bigger than you think. Only 0% of our roof area is dedicated to solar panels, and that keeps up with our yearly electrical usage.
Q:Solar Panel/Energy help?
The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
Q:How to make electricity from the sun without using solar panels?
You can use mirrors to concentrate sunlight and boil water, but I don't know if that is cheaper. You'd need motors to keep the sunlight focused on the boiler. Or you could build a solar water heater. It doesn't generate electricity but it conserves the power an electric water heater would use.
Q:how does solar panels give power to the batteries?
solar panel convert sunlight into electricity,The controller is connected between the photovoltaic panels and batteries,it makes electricity generated from solar panels charge batteries.
Q:how much would it cost to generate MW electricity by solar panels??? and how much land it requires ?
First off, you should consider cost per kilowatt-hour (kWh) since kWh is energy whereas MW is power, and kWh is a common unit of energy used by power utilities. But first you would need to design the power capacity required, which as you state, is assumed to be MW. Average system costs = $95 per square foot Average solar panel output = 0.6 watts per square foot Average solar energy system costs = $8.95 per watt Form this information, the capital cost of installing MW = $8.95 /W * 0^6 W/MW = $9 million. The lifetime of a typical solar power system is probably about 20 years. Assuming a true MW peak output of the solar panel it would be anticipated that a daily average energy production would be peak output over about 3 hours per day, or 3 MWh of energy per day. Total production over a 20 year system life would be 3 MWh * 365 days/yr * 20 yr = 22 x 0^3 MWh So in terms of costs of capitalization of the system, the cost of Energy (/kWh) = $8.95 million / 22 x 0^3 MWh = $0.40 / kWh (approximately) This cost does not include maintenance, however, given the simplicity of these systems; other than periodic equipment replacement, which is covered by specifying a 20 year complete system replacement; other maintenance cost should be relatively low. The required surface area of solar panel = 0^6 W / 0.6 W/ft^2 = 94,340 ft^2 or a little over 2 acres of panel surface area. To be able to properly access and maintain the solar array, the minimum area required would likely be 5 to 0 acres.
Q:Why aren't electronics made with solar panels?
Well if these things come up with the solar panel than no one can easily but it even run it because solar panels need constant light energy from the sun which consumes in their resources equipment. By the way these are very small things we should think about big like electricity generation still done by coal which is main reason for spreading pollution but now USA is planting solar panel plant which will help to reduce pollution and saving bills money.
Q:How to select solar panel for this application?
First, you need to make sure that your battery can take a regular 34Ah discharge without damage. The usual wisdom when using deep cycle lead-acid batteries is to allow for no greater than 50% discharge. This is to prevent the battery from ageing prematurely. Note that automotive batteries are not usually considered suitable for deep-cycle applications. Best allow for at least 200Ah capacity. Your solar panel capacity needs to take into account that whatever the nameplate output of the panel, that will be what it will produce under ideal conditions, actual output will always be less, often quite a bit less. You also need to allow capacity to cope with dull, overcast days when the light level is very low. You can get solar maps that will give you the sunshine hours and irradiation levels at your location. The solar panel capacity ends up being a juggling act between available funds/space and how critical it is that the light always works as desired. Let's say you had a 400W panel, which sounds quite generous. In the middle of winter, it may produce only 75W for 5 hours on a dull day, not quite enough to run the light for 0 hours. Would you expect several such days in a row? How many days could a 00Ah of battery capacity cover under these conditions?
