To answer this question I need to know what the amperage output is or watts and voltage for the type of solar panel you have.

If you are trying to get actual numbers, do not use the rated voltage output of the panel. That is how they get the maximum theoretical output. (that can not happen). You need to look at the source you are feeding for this voltage. A car battery, for example, is 13 VDC or so. (13.6 at full charge, 12 VDC if almost dead) You can then take the maximum current rating of the panel and determine that if not shorted, you will get about 75% of that current.

Let's assume you mean that you want 30 amps AC at 220VAC. That is 6600 watts. To get one hour of that amount of power would take roughly 8500 watts of solar panels at full sunlight. If you want that amount of power over a 24 hour period, the total panels would need to be roughly 10 times that amount, or 660,000 watts of panels. If you are buying 100 watt panels, you need 660 of them. This is the BEST case for that level of power. Your inverter will not produce energy at 100% either. We also ignore any battery loss or wiring issues. Heat is going to give you loss also, unless you have good wiring.

What energy is being converted when solar panels give energy to a light bulb?

Solar panels produce electrical energy when sunlight falls directly on them. The power of sunlight is about 1400 watts in every square metre and a solar panel converts some of that into volts and amps. Solar panels need direct sunlight falling face-on to produce a significant amount of electrical power. They also produce a very small amount of power when turned towards a bright sky without direct sunlight, and an even smaller amount on a cloudy day.


How many solar panel can generate 1 mega watt?

it depends on your solar panels, i can tell you if you know the amperage and the volts, you can find the amount of watts it produce, the equation is watts = amps x volts. hate to give you an equation as an answer


12 volt solar equal to amp?

Solar panels are rated in watts output. To find the amperage use this equation, Amps = Watts/Volts. The wattage will be on the nameplate of the solar panel.


What do I do if I want less volts and more amps from a solar panel to a battery?

You would have to add panels in parallel to get more amps and then add a variable resistance in one leg to drop the voltage to your device.


How many solar panels do you need to run central air conditioning?

This depends upon how much power each cell produces. Most home central air units need 240V, and draw aprox. 24 amps.


How many solar panels amps volt to run a 110v pool pump?

Solar panels produce DC voltages. I presume that your pool pump uses 120 volts AC. Find the amperage of the pump. Find out what the output current of a single solar cell produces. Divide this into the pump amperage. If the output voltage is 12 VDC then you will need at least 10 cells to start. The total current of these 10 cells will have to be greater that the pump motor nameplate. Now you will have to purchase an inverter to change the DC to AC.


How many amps does a solar panel produce?

It is not so much a question of amps that a solar panel produces for the consumer, as it is a question of watts, or in many cases, kilowatts. Generally, you can buy different sizes and kinds of solar panels for a range of somewhere between 3kW to 8kW, and sometimes even greater amounts such as 10kW or 11kW systems. As the wattage grows greater, the price does also, and so does the money you save from your electric company. As your question wasn't the amount of money they will save you, I will leave you to ask that question of someone else.


How do you figure out how big of a solar cell you need for a job?

You look at the job you need to do, ie, how many volts and amps, or volts and watts, that you need. Then you look in the catalogs for a solar cell or solar cell array to produce that much power.


What kind of equipment is used to collect solar energy?

There are several different ways to collect energy from the sun. The solar power (or photo-electric) cell converts sunlight to electricity. A solar furnace uses a mirror to concentrate sunlight for the purpose of heating something. Green plants collect energy freom the sun by means of photosynthesis. Any dark colored object, if it is in sunlight, absorbs a certain amount of energy and gets warmer.
