Advantages

Reason:

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.

250W 20V Polycrystalline Solar Moudle from CNBM

Q: Can solar panels be installed on sports stadiums or arenas?: Yes, solar panels can be installed on sports stadiums or arenas. Many stadiums and arenas around the world have already installed solar panels to generate clean energy and reduce their carbon footprint. These panels are typically placed on the rooftops or parking lots surrounding the facility, taking advantage of the ample space available. Additionally, some stadiums have even incorporated solar panels into their architectural design, creating visually appealing and functional structures.

Q: They have been around long enough to be cheaper. Unless they are made out of a natural material that is rare and hard to find, there is no reason why they should be so expensive. On another note, I think that all low power devices like cell phones and even laptops should have solar panels. Even if it is not enough to fully power the device for a long period of time, it will provide some electricity savings and with millions of people saving a little power adds up.: materials and process... if they could be built in a sweatshops, by kids, in Malaysia, they'd be cheap and everyone would use them

Q: Let's say I can buy solar panels for my business for $5,000 and my payback period is 8 years. Would it be correct to assume that my money is best spent elsewhere (such as paying down debt) if I am being charged an interest rate of 3.9%?: Solar panels don't financially make sense. PERIOD...at least not yet. They have a short life and the efficiency dies over time. IF you have the money then go for it, but if you have debt then financially you're probably better off paying off that debt. They're more of a luxury item than an investment.

Q: Can solar panels be used for powering a museum or cultural institution?: Yes, solar panels can certainly be used to power a museum or cultural institution. Solar panels are a sustainable and renewable energy source that can generate electricity by converting sunlight into usable power. By installing solar panels on the rooftops or surrounding areas of a museum or cultural institution, it is possible to produce clean energy that can be used to power the building's lighting, heating, cooling systems, and other electrical needs. This not only reduces the institution's carbon footprint but also helps save on energy costs in the long run. Additionally, solar panels can serve as a visible symbol of the institution's commitment to environmental sustainability, inspiring visitors and the community to embrace renewable energy solutions.

Q: For those solar panels that you install on your rooftops, do they generate electricity when it's cloudy? And if yes, how much electricity does it generate compared to sunny days? For example...like only 25% electricity generated compared to sunny days?: No, silicon photovoltaics reacts to a very specific frequency of infrared light which matches the bandgap energy of it's outer electron shell. This frequency is reflected by clouds. However, thermal solar collectors such as evacuated tube collectors can function under cloudy skies albeit at a lower rate and there is at least one hybrid photovoltaic and thermal panel designed to take advantage of this.

Q: Can solar panels be installed on a gas station or convenience store?: Yes, solar panels can be installed on a gas station or convenience store. In fact, many gas stations and convenience stores have successfully integrated solar panels into their infrastructure to generate renewable energy and reduce their reliance on traditional energy sources.

Q: Polycrystalline solar panels are good or single crystal solar energy is good: . Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.

Q: How Is heat From the Sun Transferred into Currents From solar Panels? (Explain Deeply Please): Heat is not transferred by solar panels into electrical currents. For that you need TEC or Peltier devices which at the present time are too small to do much in changing heat to electricity. You are better off collecting the heat in a solar water heater then a solar panel. Now solar panels work by the photons hitting the panel and playing kind of a billiards game. One hopes the photon will knock off an electron and the now free floating electron will make its way to your wire.

Q: My solar panel is 24long..It is set at 45deg..the arms are 8quot;long to achieve that angle for winter. I need to get to 7deg for summer..how long will the new arms need to be?..in layman's terms please...thx: You did not give the details of how the legs are attached to the panel. I did some calculations on my right triangle analysis application. Based on an assumption that the legs are vertical and attached to the bottom of the panel top, i calculated the legs must be 6.97 inches long. This compares favorably with the 8 inches you quoted. t If my assumption is true, the leg length for a 7 degree angle is 2.925 inches. The configuration, if my assumption is correct, will be a right triangle. The hypotenuse (longest leg of the triangle) is the panel length and the vertical legs are the supports. If my assumption is incorrect, edit your question to detail the support /panel configuration. TexMav

Q: With no moving parts, no fuel piping and so on...: The only way I know of is to invest the money in the stock market. Most savings accounts only pay 3% intrest. While stocks float and if you don't know what you are doing you will never make as much money as you could save on your electric bill. Then the fact that you have to pay the electric bill out of the money. In the end you rented electric and can never get your money back. You can always sell the solar electric system and get your money back plus a profit. Not many people live in the same house even 20 years so it will sell. Toss the coin. It is what ever is best for you.
