Characteristics of Polycrystalline Solar Panels

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.

Q:Can someone tell me about solar panels for homes?
I okorder.com Hope this helps.
Q:How much power is generated with solar panels?
KW solar panels generate 5kwh power each day or so.
Q:solar panels and hurricanes?
If your only deed is for power during outages, solar is not the way to go. You can add up all the wattages of the fridge and the lights you want to use, and see if the total is less than the capacity of the generator. If it is more, buying a larger generator is the answer. You can find the wattage of the fridge on the inside, or back. If not, Google the model number and manufacturer. You may already use CFL light bulbs, but if not, they can help reduce the load.
Q:What are the government/commercial incentives/discounts that come for solar panels?
Go okorder.com/ and click on your particular state. In the US today, panels are a money saver, if that, but not a money maker. Don't expect to get rich installing panels. A right-sized system will save the most money; more panels are not necessarily better. The arrangement you describe sounds like grid-tied, net metered solar. Try getting a free quote from a professional installer to see what size system would be appropriate, and how much it would cost.
Q:Information on Solar Panels?
Solar panels can convert sunlight into electricity which can be used in daily life,solar panels utilize sunrays,it doesn't discharge any polluted gas,it is environment friendly,it is also cost effective,you can make money by sell the surplus electricity to your country, On question is that solar panles have to be use in where sun is abundent.
Q:anybody owns a house solar panel system does it really save you money on electricity?

Q:How much for a 8kwh solar panel system?
Figure 8 hours of sun per day, so 8 kW-hr is a rate of kW, which is a medium sized panel, probably not enough to operate your house totally, unless you have a very small unit. Averaged over 24 hours, that is power at a rate of only 300 watts, enough for a TV. Average US home use is .2 kW, which over 24 hours is 29 kW-hr, plus you need extra for cloudy days, peak demands, and to charge batteries. You have to decide off-grid or on-grid, and if you want to (and are allowed to) sell excess power to the power company. Off gird, the cost of batteries and charge controller are a large part of the cost. On-grid, you have to purchase equipment approved by the power company to match your power with the grid. Panels will cost about $3 per watt, so for 000 watts that is $3000. Double that for installation, then add in cost of charge controller, inverter, batteries, etc. The last items depend on your alternatives, see paragraph above. .
Q:2 Questions on Solar Panels?
Solar panels come in many kinds, using a variety of technologies and sizes, but the most common is still the crystalline silicon type. The power produced is variable, but the better ones you can buy approach 20% efficiency, and the peak energy from the sun is 200W/m^2 (Watts per square meter). This only occurs when the panel is lined up with the sun on a clear day with the sun high in the sky. The efficiency is also affected by how the electrical energy is taken from the panel, and the temperature of the panel. In the full sun the temperature approaches 60C, so the voltage drops. The links below provide a lot of information about such matters. A BP panel 50mm x 674mm gives a peak power of 20W. This is .07 square meters. As you can see this is very close to 20%. (The third link). However this is less in practice because the sun may not be full sun and may not be perpendicular to the panel. The output drops as the cosine of the angle to the sun, more or less. Even with peak sun this would produce only about 00W charging a 2V battery directly, unless an electronic Maximum Power Point Tracking (MPPT) charge control is used.
Q:Do grid-tied solar panel systems have to be installed professionally?
By an utility approved qualified individual. The utilities really hate it if their maintenance people working on the power lines gets electrocuted because some solar powered inverter didn't shut off when they shut the line off.
Q:what does a single solar panel weigh?
A single hexagonal solar panel weighs around 0 to 2 pounds (see link). A conventional silicon solar panel might weigh 40 pounds.
