Q:solar panels, wattage?
The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.
Q:Have a question about mobile homes and solar panels!!!?
My guess is that you will pick up everything concerning solar power at www.okorder.com.
Q:Can a solar panel work with an inverter?
There could be a couple of reasons why it isn't working. First, 2V panels actually put out a considerably higher voltage because it is presumed that they will be used to charge a 2Vdc battery. That requires applying a voltage greater than 2Vdc, and usually there is a solar controller that regulates the solar power to the battery. It also has a voltage drop. Look at the first reference reference, and you will see these values for a particular panel: Voc: 2.6V (open circuit voltage) Vmp: 7.2V (voltage at maximum power point) Voc is the voltage the panel produces under standard sunlight and temperature conditions (25°C), with no load applied. As load is applied, the voltage drops (see reference 2). Power is the product of current times voltage, so at one set of conditions (namely at Vmp) maximum power is available from the panel. Your inverter might not be working for either of two reasons: ) it has input protection circuitry that locks out operation when it senses an overvoltage, as in the 2.6V open circuit voltage, or 2) the panel does not produce enough current and the voltage from the panel collapses under excessive load. For example, if you load your inverter to 20W, then nominally the 2VDC input to the inverter must supply 20W/2V/eff = 0A/eff Assuming the inverter has an efficiency of 80%, the input current required is: 0A/.8 = 2.5A A solar panel operating at maximum power would need a rating of about: 2.5A x 7.2V = 25W Is your panel that big? The other option, as mentioned by others, is to charge a battery that runs the inverter. Other nuances: Voc increases as temperature decreases. Sunlight intensity varies (obviously), so the panel may produce less than rated power. The power specifications often are printed on the back side of the panel.
Q:Are photovoltaic cells the same as solar panels?
Yes, they are the same thing.
Q:how much money does solar panels save?
even although photograph voltaic panels cost quite some funds up front and don't furnish a hundred% performance, over the existence of the device, a photo voltaic panel array can shop maximum folk funds. producers furnish 25 365 days production guarantee on panels and panels will often proceed to supply after the guaranty has expired. whilst a device is designed to supply 'internet metering' truly producing as a lot power a house makes use of it (the two by way of batteries or pushing it back on the grid the payback on the cost of the panels would be measured by way of dividing the device cost by way of the month-to-month power expenses. With the passage of a 30% federal tax credit on qualified platforms and assorted state classes, platforms will payback often in under a decade consistent with utilization factors and climate.
Q:How to wire solar panels?
i'm involved approximately do-it yourselfers, i'm one, yet... Sorry to inform you, yet connecting image voltaic panels to grid capacity will require an electrician. there are a number of standards for specific disconnects to circumvent harm to the utillity corporation workers that would desire to be seen. you will additionally might desire to have an inverter sized to verify your panels. the straight forward answer is to connect your panels to something specific, without connecting it into your place wiring. An occasion is to connect your water properly pump to image voltaic capacity and disconnect it from the grid. yet you will nonetheless want an inverter and could might desire to calculate the capacity demands of the pump and the quantity of capacity available out of your panels, which varies via your longitude and variety. It sound like an straight forward element to do, yet without specific training and adventure you would be sorry in case you attempt this your self.

Q:how do i fix my solar panel? please hurry i need it for my science fair project?
If that solar panel came with the car, the panel is most likely defective. Make sure you're in bright sunlight, and try holding the car so that the wheels are not touching the ground. If the wheels still won't turn, even slowly, then the panel is bad. If each person in the class got one, see if you can try your panel on a friend's car, or their panel on your car. If this is just any little panel, it could be that the panel simply does not have enough voltage, current, or both to power the motor on the car.
