Specification of Solar Polycrystalline(270W-290W)
CNBM Solar photovoltaic (PV)module is designed for large electrical power requirements. It is the optimal choice for both on-grid and off-grid power systems. CNBM Solar panel offers high performance of power per square foot of solar array.Poly- or multicrystalline silicon(poly-Si or mc-Si): made from cast square ingots — large blocks of molten silicon carefully cooled and solidified. Poly-Si cells are less expensive to produce than single crystal silicon cells, but are less efficient. US DOE data shows that there were a higher number of multicrystalline sales than monocrystalline silicon sales.
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: Can solar panels be installed on a metal roof?
- Yes, solar panels can be installed on a metal roof. In fact, metal roofs are often considered an ideal surface for solar panel installation due to their durability and longevity. The sleek, smooth surface of a metal roof provides an excellent mounting platform for the solar panels, and the panels can be easily attached using specialized mounting brackets designed for metal roofs.
- Q: do solar panels create electricity from the ultraviolet light created from the sun? because they only have an efficientcy of like 8% and this scientist found out a way to collect the visible light also, and he says the solar panel could have an effeciency of up to 80%! so my question really is, do solar penels creat electricity from heat? do you know of anything that can?
- Not many people realise it, but Einstein did not win the Nobel Prize for either Theory of Relativity. He was awarded the prize for his work on the photoelectric effect. i.e. the ability of some materials to take photons of light and turn their energy into electricity. Now, since most of the Sun's UV rays are filtered out by the Earth's atmosphere, else we'd be able to get a sunburn in seconds walking around outside in daylight, I think there is some energy imparted to the solar cells by UV wavelengths of light, but most solar cell materials rely on the wavelengths of electromagnetic radiation we call visible. Plus, I always thought infrared wavelengths conveyed more heat energy than UV rays.
- Q: Can solar panels be used in areas with high levels of dust storms?
- Yes, solar panels can still be used in areas with high levels of dust storms. However, it is important to ensure regular maintenance and cleaning of the panels to prevent dust accumulation, which can reduce their efficiency.
- Q: Can anyone give me a link to a website that sells really big solar panels? Enough to run a small cafe on entirely solar power.
- I cannot offer a source of info, but... Solar power is great, but not ideal (yet). Currently, one-story buildings that have a rooftop totally made up of solar panels can only get about % of the power needed by that means. Additional panels will be needed.
- Q: I was hearing that we need silver as a medal for the creation of solar panels, is this true? How much silver would be needed to make one solar panel? (if this is true)
- Some research has shown that small amounts of silver can improve the efficiency of solar panels. But this appears to be in the research stage and applies to the the thin film solar cells. Some solar panels makes use silver as the wiring in kind of a screen printing process, but you don't need to use silver, you can use copper or aluminum using different techniques instead. Generally the metal used is in small amounts and not a majority of the cost of the solar panel.
- Q: What is the impact of roof material on solar panels' performance?
- The impact of roof material on solar panels' performance is significant. The type and condition of the roof material can affect the efficiency and effectiveness of solar panels. Certain roof materials, such as metal or asphalt shingles, are more conducive to solar panel installation and can provide a stable and durable surface for the panels. These materials typically allow for better heat dissipation and can withstand the weight of the panels. On the other hand, roofs with clay tiles or slate may require special mounting systems and can be more challenging to install solar panels on. Additionally, a damaged or deteriorating roof can pose a risk to the overall performance and lifespan of the solar panels. Therefore, it is crucial to consider the roof material and its condition when planning for solar panel installation to ensure optimal performance and longevity.
- Q: Are the solar panels on the roof just a gimik to get all the tree huggers to buy it, or are they actually a good, efficent design?
- The solar panels run the fan to remove hot air from the car. They do about the same amount of cooling that cracking the windows and using a heatshield over the windshield--that is they keep the interior of the car about the same as the exterior without draining the 2V battery. One problem I have with the solar panels is that they come with a moonroof. The other problem I have with them is that to get them you have to give up the additional safety features because Toyota won't put both the high tech safety features and the solar panels on the same car. So is it a good design? Well, nothing with a sun/moonroof is a good design IMHO, but that's the power of advertising for you. In that it runs a fan without draining the 2V battery, yes that part's good. Having to give up the high tech safety features to get it makes it a non-starter for me (and I live where it gets plenty hot so I could really use the fan).
- Q: Can solar panels be installed on a boat or RV?
- Yes, solar panels can be installed on both boats and RVs. They are a popular and efficient way to generate electricity while on the move. Solar panels can provide a reliable source of power for charging batteries, running appliances, and lighting, making them a great option for sustainable energy on the go.
- Q: if i was to put a solar panel (sp) just outside of the earths atmosphere ans another solar panel (sp2) 0km away towards the sun. which one would generate more power (sp or sp2)? and how much more? is there a ratio to work out the power output and distance from the sun? would the 0km distance between the panels make a large difference in power output?many thanks in advance
- You do realize that the sun is 50 million km away don't you?
- Q: How much does 000 square feet of solar panels cost? This is for a pool with dimensions 75ft by 25ft? How much will it cost including installation fee and the water heater?
- My Father-in-Law had around 300sqft of solar panels installed for the equivalent of around ?3000 or $5000. These were just the cheap and relatively inefficient black plastic tubes that were installed on his roof. This was in South Africa where the labour rates are quite cheap. The system works okay and heats a 40ft x 20ft outdoor pool to over 30C in the height of summer. Rather than a pool heater, I think it might be good to look at an air source heat pump to help heat the water in Autumn/Winter when you don't get enough sun to heat the pool. These will be expensive (over $5000), but they will use less than 30% of the electricity of a standard electric water heater. Just the solar panels could cost you $5-20K including fitting.
