Q:how does solar panels give power to the batteries?
When sun light reaches solar panels, it releases electrrons to make an electric current. They are made od silicon or germanium which has this property. Photons in the sun light when hit on semiconductor like silicon, releases electrons o make the current flow.
Q:Hi trying to learn more about Solar panels!?
Solar panels do not store power. Solar panels convert sunlight into electricity. To store power you need batteries. The usual type of batteries used are lead-acid deep discharge( similar to car batteries). The batteries are charged up during the time the sun is out. However, as a backup you could also have a generator handy to provide power for times when the sun did not shine enough to keep the batteries charged up.
Q:kilowatt solar panel help?
You would be amazed how often I have answered this question. The answer is that it depends on your latitude and local weather . Let's see if I can give you enough information so that you can determine the answer for yourself. A kW solar panel is rated at kW when it is exposed to a solar flux of kW/m^2 (called a peak sun hour). There are readily available tables of effective peak sun hours per day by city (see Reference ). Let's use Fairbanks, AK as an example (it is the first line of the table). Fairbanks get an average of 3.99 of peak sun hours per day on average. So your panel would produce 3.99 kW*hr per day on average.
Q:Connect Power Outlet to Solar Panel?
Most efficient manner would probably be to use solatubes, or sun tunnels during lighting hours, then replace the 500 watt lighting system (assuming it's incandescent) with LED's, that should give you about the same light output for around 00 watts or a little less even. Then you need a solar panel that can produce 00 watts for as long as you want (at a 00 watt lighting system) or 200 watts for /2 the time you want, etc, etc. Allow a good 0% or so for inverter inefficiencies, and 0% or so for reserve, so 20 watt's per 00 watts. After you have this, you will want a charging controller, a battery, or battery bank (These should at very least be deep-cycle, or better yet golf-cart batteries with series between 2, and parallel between banks of 2 for the 2-volt portion of the system), with enough amp-hours to support your system, plus a good 0% or so reserve, plus another 0% or so for inverter inefficiencies (remember the over sized solar panel above, this is why), than of course you also need a 2-volt DC to 20-volt AC, 60 Hz system (or 240 volt AC 50 Hz system, depending on your AC system) inverter.
Q:How does solar panels work?
Since you said does instead of do I think it would be fruitless trying to explain it...
Q:Cost of a solar panel?
That's more like a bare laminate, and will not be durable, but will get you a legitimate $/watt. Also understand that if a manufacturer has a cost of $/watt, that means the panel will cost more by the time you buy it. It has to be shipped, stocked somewhere, and the retailer has to make a profit. $560 is high for a 20-watt panel today. Whoever is selling at that price will not sell many, or will sell only to those who aren't shopping around.
Q:how to power a 400 watt heater with solar panels and batteries?
You could do that, but it would be an expensive way to go. If what you really want is heat, consider heating water directly with conventional solar water heaters, and storing it in a large, insulated tank. You can then circulate the water through a conventional radiator at night.
Q:if you put solar panels on cars, you'll be able to drive without gas in the summer and part of winter?
Yes. But you won't be able to go very fast. If you fill up the roof, hood and trunk lid of for example, a Toyota corolla, with the most efficient solar panels you can buy, you might get 2 hp in the mid day sun. That could push the car maybe 2 mph on a flat, and wouldn't get it up a hill unless it had super low gearing. In order to go fast enough on solar power to make it worth while, you need a large area of solar panels and a super light car. Like an aluminum tube frame with a foam and fiberglass composite body, skinny, high pressure tires and a solar array 6 ft wide by 2 feet long. A car like that, with good aerodynamics and a 6 hp motor could get up to 45 mph eventually, just slowly. But it's impractical because it's not safe to drive it with other cars around. But who says the panels have to be on the car? If you have a solar array that feeds as much power into the grid as you take out, that is essentially equal to being solar powered in all practical ways. Even if your car can't be entirely solar powered, that don't mean you shouldn't use solar panels. You could use solar panels in any car, to supplement battery charging, taking load off the alternator, and you would see an increase in fuel economy. There is a system on some cars that uses solar power to circulate air through the cabin when the car is sitting in the sun. This keeps the car up to 30 degrees cooler, taking a huge load off the air conditioner, so instead of pumping all that heat out, you simply vent it into the air, and there is an increase in fuel economy for a few minutes. Every little bit counts.
Q:how the energy of solar panel measure?
A solar panel is made up of solar cells. Each cell produces about 0.5 to 0.6 volts. Cells are connected in series, like the batteries in a flashlight. Enough cells are placed in series to produce the desired voltage. Cells produce very little current, so many strings of cells are connected in parallel to produce sufficient current. The output is direct current (DC), like that from a battery. A home solar system needs alternating current (AC), so an inverter is used to change from DC to AC. Some systems have batteries for backup power. In these some of the DC output is used to keep the batteries charged. Systems are measured in kilowatts. System sizes are chosen to meet the demands for electricity. My system has a 6 kilowatt (kW) rating. The true output is more like 4. Now that you know this much you can Google SOLAR SYSTEMS to learn more.
Q:can I run a desktop computer with a solar panel?
The system in the Hawaiian house has solar panels that charge a battery bank. If the sun doesn't shine enough, the generator will kick on and provide the extra power needed. An inverter converts the DC voltage stored in the batteries to AC power that you plug into a wall outlet to use. Depending on the inverter, it should be exactly the same as the AC you buy from the electric company now, so anything that you currently plug in to use will work. The exception is if they are using an inexpensive modified sine wave inverter, that doesn't generate as clean power as a pure sine wave inverter. Some delicate electronics may have trouble running on it. You may want to ask the house owners which type of inverter it is. If they don't know, ask them the model and you can easily look it up.
