Characteristics of Polycrystalline Silicon Solar Panel

I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

IV AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.

V Junction box: Multi function junction box with water proof.

VI Long lifetime: ≥25 years; Less power decrease.

VII Good performance of preventing from atrocious weather such as wind and hails.

VIII Resisting moisture and etching effectively, not effected by geology.

IX The certificate issued by international authority: UL, TUV, IEC, VDE, CE.

Q:Advice on Solar Panel....................................?
Unfortunately solar panels aren't very cheap, and to power as much as you would like, you'll need quite a few. Aside from that, they aren't the most dependable, and maintenance is pretty expensive. If there is a relatively continuous breeze in your area, you may want to look into residential wind turbines. They will provide electricity 24/7, and the small ones don't require very much maintenance. You won't need as many turbines as you would solar panels either because they provide a pretty decent amount of power. Hope this helps!!
Q:How much energy does it take to make, install, and eventually dispose of a solar panel?
The attached link is to an article from the 200 Home Power magazine. In that article the energy payback was found to be between 2 and 4 years. Newer panels are more efficient primarily because the silicon wafers used today are thinner. The silicon cell embodies most of the energy required to make a solar panel. Today most solar panels will produce the amount of energy required to manufacture them in between about 9 months and 2 years depending upon the specific technology used to make it. Solar panels are expected to produce energy for between 30 and 50 years. Therefore it takes around 5% of their total energy production to produce them. Note that these figures depend upon where the panels are installed. Panels in very sunny areas may generate more than 3 times the energy of panels in a cloudier area. Edit - The energy payback meta-study that carbonates references below mention one particular study Alsema (2000), which the authors used as a baseline to come up with their 4 year payback figure. These studies DO NOT assume ideal conditions. The Alsema study assumes an annual an irradiation of 700 kWh/m2/yr. That is the United States average irradiation and does take into account cloudy weather and the like. Under idea conditions the amount of energy collected can be almost twice as much. Albuquerque New Mexico is an example. The figures I mentioned above are recent values reported by several different panel manufacturers with whom I discussed the issue at the 2006 IEEE 4th World Conference on Photovoltaic Energy Conversion held this May. The very long payback times that carbonate highlights are almost certainly wrong. The study he references concludes that paybacks range between 2 and 8 years with 4 years being the most likely. In my opinion payback times are actually a fair bit shorter based on conversations with the manufacturers.
Q:Has anyone used portable solar panels for home use?
I think you'd be disappointed. But you might be able to take an RV, park it close to your house in the sunshine, run an extension cord from your house connected to a small fan and run the fan for free. I don't think it's worth the expense of the RV, but that's me. If you have the money, flaunt it baby, flaunt it.
Q:what do solar panels do?
Solar panels (or photovoltaic panels) collect either light energy (photons) or heat which is then used as energy. Because a single panel can only produce a limited amount of power, there are normally more than one installed.

Q:question about Solar Panels?
Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
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:The voltage and power problems of solar panels
Because the MPPT controller has a wider input voltage range, it can also convert multiple voltages into current charge and better protect the battery.
Q:How many solar panels do we need to power the US?
well the main problem is that the the solar panels are ineffecent due to their 5 lays(that is what i hunrd they are useing in Gemrnay). Also if i remember right we are at a 20% conversion rate on solor panels. their is 2 problems with solar panels. the weather they drom in effeceny everytime the a cloud get in the way of the sun. what are u doing to do when it gets dusk time? tho neucler power is a good idea. it is only good for the Base load not for the peek power times... IE; Quiting time when everyone gets home and flips on the AC. The best thing really would be Geothormal, nucluer, wind and some solor. but that is for the west out word.. the south is still SOL. So they would need bio fules, better coal plants and fuel cells. (witch is where i am going to start working on here soon )
