250W Monocrystalline PV Solar Panel in China

Advantages

We enjoy exclusive channel to get stock solar panels at more competitive price from Trina,Hanwha,Yingli,LDK,Suntech etc.

These panels are from tier 1 solar panel manufacturers,such as Trina,Hanwha,Yingli,LDK.They are assembled with all grade A materials,only problem is that they has slight appearance defect,but due to their strict quality control,even the negligible defect will lower its grade.so they put these panels into stock.

Quality

These panels adopt all grade A materials,such as solar cell,EVA, back sheet, junction box, glass,frame,connector etc.

They have same electrical performance with grade A solar panels,only difference is the negligible superficial defect.

Q:Can solar panels be installed on a multi-story building?: Yes, solar panels can be installed on a multi-story building.

Q:I just bought a quot;00 wattsolar panel system to install on my house. I just wanted to know if by 00 watts, does that mean per hour, min, day week or what?: You will need many more to do any good.

Q:Can solar panels be installed on a warehouse or storage facility?: Yes, solar panels can be installed on a warehouse or storage facility. In fact, these types of buildings often have large, flat rooftops that are ideal for solar panel installation. Installing solar panels on warehouses or storage facilities can help generate clean and renewable energy, reduce electricity costs, and contribute to sustainability efforts.

Q:Can solar panels be used in cold climates?: Yes, solar panels can be used in cold climates. While the efficiency of solar panels may slightly decrease in colder temperatures, they can still generate electricity even in freezing conditions. In fact, solar panels can even benefit from the reflection of sunlight off snow, which can increase their output. Additionally, advancements in technology and the use of anti-reflective coatings have improved the performance of solar panels in cold climates.

Q:The ancients used skylights for light in lieu of electricity. Light was used for drying, even cooking foods and drying clothes. Solar clocks/sun dials were once popular but now we have battery operated clocks. Where have we tapped into any of these resources since the outdated solar clothes drier nicknamed the 'clothes line'?: Have you seen the industrial solar power tower they built in Spain? It has a very large collection of mirrors which direct sunlight toward a single point at the top of a large tower. There a boiler turbine generates a lot of electricity! It is a genius concept that could easily be installed in North American deserts.

Q:Can solar panels be installed on fences?: Yes, solar panels can be installed on fences. In fact, installing solar panels on fences is becoming increasingly popular as it maximizes space utilization and allows for efficient energy generation in areas with limited roof space. Additionally, fence-mounted solar panels can provide added privacy and security benefits.

Q:What direction do solar panels usually point? North? East? South? West?: The general answer is toward the equator, so south when the array is north of the Tropic of Cancer, and north when south of the Tropic of Capricorn. In the equatorial zone, one would often still point towards the equator, but other factors such as wanting the panels to efficiently drain rain and dew come into play. But wait, not so fast. Financial considerations dominate in some areas. When afternoon electricity costs more than morning electricity, it may pay to have panels oriented southwest in the northern hemisphere. Where electricity costs the same all day long, it may pay to orient the panels southeast, to harvest more in the morning, when temperatures are cooler, and the panels are more efficient. For solar hot water, SW is usually optimal in the northern hemisphere, because of higher ambient temperatures, and also the usage pattern of most people using the hot water when they get home in the evening. A local installer that has been around for several years will know what orientation is optimal for your area.

Q:Hello, I am shopping for solar panels for my home and there are so many to choose from. My house uses 40 Kw of power a day. If you had to choose from the output power of a solar panel from below, which one would you choose and why would you choose it? 2 Volts 4 Amps 48Watts2 Volts 8.5 Amps 02Watts6 Volts 7 Amps 2Watts24 Volts 4.2 Amps 00.8Watts24 Volts 8 Amps 95Watts: the last one has highest wattage. that will bring down the total number of panels you need to meet 40 KW. you probably need 220 panels

Q:What is the typical warranty period for solar panels?: The typical warranty period for solar panels is around 25 years.

Q:Does anyone own any and would you recommend them? right now i only own solar stake lights and i use them during the summer in my yard. But during the winter i take them out because they don't charge well. I live in toronto canada where it snows a lot during the winter, would it even be worth it to buy solar panels? Would they get covered with snow if the were mounted on my roof and get ruined? I plan on buying some when i purchase my own home.Any info would be appreciated:): I okorder ... to size a system for your home. There is a link on the page to a world solar insolation map so you know how many sun hours you have per day on an avg. Should not take you more then a half hour to get a good idea of what it will cost you and which package system should work. Good luck on going green and don't let the Oil and Nuke people bring you down. They are just looseing money when you make your own power and their nuke power plant goes off line and not replaced. Some one above said solar cost more.. That is not true. I don't know about other countries but here the cost of living is about 3.5% per year so it is compounded each year. Then there is the rise in fuel cost which is 6.5% per year which will increase. But think about it you are buying 30 years of electric for 34000 dollars. If your electric bill was at current prices 00 dollars a month you would pay 36,000 dollars in 30 years. Now add in the 3.5% cost of living compounded each year for 30 years and the fuel increses . You will pay the public utilie 00,000 in that time frame
