Product Description:

1. Structure of  Polycrystalline Silicon Solar Modules 250W Description

Solar panel refers either to a photovoltaics (PV) module, a solar hot water panel, or to a set of solar photovoltaics modules electrically

connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells. Solar panels can be

used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Each

module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. The efficiency of a

module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16%

efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only

a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar

modules, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q:Im a bit confused about what a solar panel is?
As Aviophage says, there is plenty of info around. Solar panels produce electrical energy from the sunlight's energy. The sun puts out around 00W per square meter, and the panels are up to 20% efficient at converting this. If you are looking for a Grid Connected power system, they are usually made up of 24V modules about 50W each. The full voltage produced is then around 50V to 500V DC depending on the sun etc. They are connected to a specialised grid connect or grid interactive inverter (look up Sunny Boy for an example) which converts this to mains power for use around the house, while any remainder is exported to the supply network. The supply company may buy this at premium rates, and governments may provide subsidies to approved installations. There may also be carbon credit certificates when you buy a system. Not all places allow such things to be connected to the grid, but this market is rapidly changing. The links below should get you started.
Q:How did Obamas funded solar panel plan flop and bunkrupt..where did those billions of dollars go?
Down the drain. That money is gone. Just more wasted money the government writes off and then tries to raise taxes to pay for.
Q:Where to buy cheap solar panels?
There are ton's of distributor around that can provide you a cheap solar panel that didn't came from China. Expand your knowledge and learn from a renowned solar company about the Best Solar Panels. Visit our site and contact us today!
Q:Has anyone used portable solar panels for home use?
from what i have seen and heard the portable panels you are talking about are not big enough for home use unless you create a specific outlet to use them on such as one for cellphone charger or other small use items. Just my semi-educated guess.
Q:A question about solar panel?

Q:I need a lightweight form fitting solar panel with the best power potential?
Q:How many Solar panels?
If you have 480 volts, it might be 3-phase, and not a simple matter of multiplying volts and amps. However, that's in the ballpark of 25 kW, very doable for solar. That's on the high end of a residential installation, but very small for an institutional installation. What will influence the size of the array more is where you are geographically (that is, how much sun you get), and how often the motor runs (that is, how much energy in kWh does it use per day)? 480 volts is nothing to be trifled with. You should really get a power engineer to architect your system.
Q:adding more solar panel & battery?
That charge controller is notoriously cheap and burns up easily. If you are going add solar panels, also buy another charge controller to go with them. They can both be connected to the same battery bank. I don't believe the kit comes with batteries, so you would buy whatever size 2V battery bank your power requirements call for. The size of the inverter depends entirely on what you are going to power with it, not the size of the panel array. As long as you are not powering anything that is over the 300W rating, you don't need a new one. Just be sure to check the details of the inverter, is it 300W continuous, or can it handle up to a 300W surge? Also, it's a modified sine wave inverter instead of a pure sine wave inverter, so don't plug any sensitive electronics into it. They may not work, or you may get a buzz or hum from it.
Q:Are DIY Solar panels legitimate for saving electricity?
Hi Mitch, Yes they are legitimate ans so much so the government will actually help you pay for them. Someone has already mentioned if you purchase them from your local solar panel installer they will not be cheap.They have come down in price a lot over the last couple of years. Yes you can build your own and no its not too difficult.You need to know in your own mind whether you just want to reduce your utility bill or come off the grid completly. The best solution is a combination of wind and solar power and yes you can build your own windmill as well and at the bottom her I will show you where to go to get easy non technical plans. Naturally the sun does not shine at night so your solar panels would not work then but windmills function 24/7 as long as there is wind. If you have nearby neigbours please be aware windmills do make some noise which might upset your neighbours and of course see if you need planning permission from the town. The solar panel plans show you how to set an 80w solar panel which of course would not be able to power your whole house,but once you have built one why not build loads more and each one will get easier to build. Wish you all the best.
Q:Do solar panels effect birds and/or other animals?
My solar panels have provided a home for birds, they nest under them. I don't think we should worry about the glare of a solar panel when it is placed on a building that eliminated the habitat that used to be there. Glare is such a minor issue compared to eliminating food and shelter for many animals.
