First of all, you can't connect a sink that requires a constant power, since the power of a solar cell is intermittent, due to the intermittency of the solar irradiation. 45W will be the peak power, so that is only reached under ideal solar irradiation conditions. If you reach the 45W you could e.g. connect a few energy saving light bulbs to it.
can a 500 watt solar panel run a 500 watt appliance with 2 102 amp deep cycle batteries
only if u use a battery to boost power ,
One 25w solar panel for one 100w bulb. A 100-watt solar panel can produce about 400 watthours of power per day. A typical home consumes about 25,000 watthours per day. So you would need 62 one-hundred watt solar panels to run an average home.
Solar panels are ridiculously expensive. A small 130 watt unit costs almost $600. To run your house on solar panels you are looking at thousands of dollars.
A 20 watt solar panel produces 20 watts of power/hour when it is in direct sunlight. However, this varies depending on the conditions. It won't produce at 100% in cloudy conditions. Let's say the 20 watt panel gets about 5 hours of good sunlight everyday between 10am and 3pm. This will produce .1 kWh or 100 watt hours. This means you can run a 100 watt bulb for one hour or two 50 watt bulbs for one hour.http://www.heatingandcoolingcompanies.org/
You can run up your credit card account.
Yes, the DC 12 v 8 amp fan can be operated by a 150 Watt solar panel.
To do a proper caculation you have to know what the amperage of the gate motor is. The amperage of the load is what governs the size of the wire. There are two ways to power a Gate opener DC OR AC. Smaller units and residential units are generally DC. Larger commercial are usually AC or use a combination of DC and AC technologies. I will assume it is a DC operator being powered off a battery, with the solar panel maintaining the battery. As for the solar panel the panel was probably a 5 watt not a 5 amp, as a 5 watt panel is generally the smallest panel you would want to use to supply power to a gate operator. This supplies a trickle of power at 12V which charges a 12V battery. These panels generally charge at or less than 500 milliamps.Generally #16 would be fine for such a length.
If by unit we are asking about a watt, he cost for the panel is about $3.00 a watt. Double this price for installation. The cost of a kilowatt (1000 watts) from your local utility is about $0.10 or $0.0001 per watt. This means you need to use the panel for 6000 hours to break even. Typical sunlight in Wisconsin averages two hours a day and you get about 75% efficiency from a panel. This means you need to run the panel for 4000 days to break even. Typical panels last about ten years. Their life is determined by their breakdown in sunlight.
NO!!! they run on sunlight... JFC use your brain.
biggest u can afford!
It's not the voltage that really counts, it's the wattage of the things you intend to run by the solar panels that counts.
