Poly Solar Panel 270W B Grade with Cheapest Price


Product description

 form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.


Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.

Q:How does Solar Panels works and what is the cost of getting a solar panel installed.?

Q:Information on making solar panels?
I doubt that you are going to want to learn how to dope your own silicon wafers, add contacts and laminate them into PV panels.  I also doubt that you're going to even want the various chemicals to make e.g. cadmium-based cells anywhere near your house (cadmium is a very toxic metal).  In other words, making your own solar panels is not an at-home project. You can buy solar panels based on cells of several different types.  A link to a Pricewatch-like website for current prices on solar panels is below.  Mounting panels to roofs or pole mounts, running conduit and wires, and installing battery banks and inverters are within the capabilities of skilled laypeople. More data at the links. Edit:  I am reporting all of Agua-Luna's cut-and-paste pieces as spam.  I encourage others to do likewise.
Q:how to store energy from solar panels?
I have no idea what you are doing or what you think you are accomplishing. A 235 watt panel isn't much energy. You can certainly store it with a plain old lead acid battery.
Q:How Do Solar Panels Work?
Solar panel or solar cells are semiconductor that generates electric current when expose to a light source such as the sun. It is a large diode that is capable of generating elctricity.If building a project you have to weigh the voltage and current requirements against the panel size ie.. 5x5 inches may be able to generate 00milliamps at 5 volts in bright sunlight.
Q:DIY solar panels for Gride tie?
Congratulations on your solar panel. It takes a lot of work to construct one. Tying to the electric grid requires permission from your power company, and conformance to local building codes. This generally means compliance with the National Electrical Code (NEC), meaning your panels must be UL (or similar rating from another standard) listed, for fire and electrical safety reasons. Homemade panels won't qualify, unfortunately. I really would discourage you from trying to do a jungle installation without permission, as the power distribution in a house is nothing to be trifled with. That would also likely void your homeowner's insurance, and give the bank a reason to call your mortgage, if you have these.
Q:Solar Panels power help?
What you really need to calculate is your energy requirements, you are only stating your power requirements. Power (W) = how many watts of power are you using? Time (h) = how long are you going to use the power for? Energy requirement(Wh) = W * h take the answer to that equation and plug it into the exact same equation except substitute how much sunlight you get for h and then solve for W to find what you need in the way of a solar panel. Wattage of solar panel (W) = Energy requirement (Wh)/hour of sunlight per day (h) Now you know what wattage of solar panel you need. For the battery you use a different equation: Energy in the Battery(Wh) = Battery Voltage (V) * Current Capacity (Ah) Solving for Current Capacity: Ah = Wh / V This will tell you how big a battery you need, but you also need to be concerned about how much current it can source. For this you need to know what your peak power requirement is. Wmax = peak power requirement Max discharge current (Amax) = Wmax / Vmax Also you will need an inverter rated to Wmax as well.
Q:making your own and installing solar panels. Bull s*** or not?
If you're in Hawaii, number one, be sure to get a solar water heater. Guaranteed fast payback. Now about those kits. Avoid the kind that says you can make your own panels for under $200. Those are scams. If you're in CC of Honolulu, you will not be allowed to connect that kind of panel to your house - it doesn't meet National Electrical Code because it doesn't have a safety rating like UL. There are kits for grid-tied solar that run from $6000 on up. That's the kind that can actually save you money. I don't know whether you are allowed to install it yourself, though. In California, you can, as long as you get the inspection, same as any other building project. In spite of being further south, Honolulu gets about the same amount of sun as we do in San Jose, California. That's because our area is dry, and you have more clouds and rain during an average year. If you're in one of the wet valleys like Manoa or Palolo, obviously the situation would only be worse. But your electric rates are high, so you have a good chance of making your money back. Very few sites are really good for wind turbines. You cannot just put it on your roof in the city - it needs to up high, where the wind is strong and steady. That's why you see turbine mounted on towers. Also, because it has moving parts, it's going to wear out. Finally, you know how cars rust out quickly there compared to the mainland? Same thing with a wind turbine.
Q:Solar panel connected to battery ??
You really need a little more infomation about your battery. It should have a recommended range of charging current. You should not exceed that range. Your solar cells must be a higher voltage than the battery, but you should not connect the cells directly to the battery. First, you need a diode in the line to keep the battery from draining into the solar cells when there is no light. Second, you need a resistor to limit the charging current. You have a 3.6v battery. Let's say the charging current is 0.A. Use a 5v solar cell and silicon diode. The diode will drop the cell voltage to 4.3v. The voltage across the resistor will be .7v for .A current, you need a 7-ohm resistor.
Q:Can a solar panel be used as a NiCd cordless tool battery charger?
Your 5W solar panel has to put out about 5 volts or higher to charge a 2 volt battery. 5 watts at 5 volts is only 0.3 amps, which is only enough to handle the internal leakage inside a large battery, plus a bit. If you have a 00 amp-hour battery, that panel would take 300 hours of bright sunlight to charge it. But I do agree that it will keep the truck battery charged as long as it gets sun. Make sure you put a diode in series between the panel and the battery to prevent the battery from discharging through the panel when the sun goes behind a cloud. I'd be worried that if you charged the 8 volt battery frequently, the panel would not be able to replace the lost charge, and your 2 volt battery would wind up discharged. That 8 volt battery is .2 amp-hrs (if I got the correct one). That is 27 watt-hours. Allowing for losses, you car battery will have to deliver over 30 watt hours to charge it. Your solar panel will take over 6 hours of bright sun to make up that difference. That is over 24 hours this time of year. So if you recharged it more than once every 2 days, you will lose charge in the truck battery. .
Q:cost of solar panels?
It all depends on where you live and who you get them installed by.
