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: Any recommendation for best solar panels?
- If you are looking for the best solar panels, you should know that there are a variety of top manufacturers such as SunPower who make these panels. When shopping for solar panels there are a variety of choices you will need to make including what kind of panels you prefer. There are two main types of solar panels, traditional PV panels and thin film panels. GE solar panels are an ideal choice for residential, commercial or even industrial customers who want to harness the power of the sun. Hope the recommendation is good.
- Q: Hi. I need to build a solar panel for a project. it should be able to light a 60 watt light bulb. also, it should be about 3x3 ft if it is 50% efficient. if anyone knows any websites or can help me, please answer! thanks.
- I don't have any practical experience building solar panel arrays to power a given device, but allow me to make this observation. Solar cells, when exposed to sunlight, will each generate a given amount of power (watts), and by wiring these in series, you will increase the wattage. Now, a panel three feet square will give you a certain amount of power, provided all the cells are wired correctly in series, and it may not provide enough juice to light the bulb. You can work around this by adding a step-up transformer (which takes the incoming power and boosts it to the desired level for output, with no moving parts). Voila! You've illuminated your bulb. I will admit, though, you'll have to do some math to determine what you need. A search on the Web will help you find the formulae and other information you'll require. Good luck.
- Q: Can solar panels be installed on a house with a flat roof?
- Yes, solar panels can be installed on a house with a flat roof.
- Q: How do solar panels impact the electric bill?
- Solar panels can significantly reduce or even eliminate the electric bill. By generating electricity from sunlight, solar panels can offset the amount of power needed from the grid. This means that homeowners or businesses with solar panels can consume less electricity from the utility company, resulting in lower energy bills. In some cases, excess solar energy can be exported back to the grid, earning credits that further reduce the electric bill.
- Q: Can you please tell me how much a solar panel costs?Please back up your info with a website.
- Have okorder . Possibly this could immediately instruct each and every one!
- Q: Can solar panels be installed on a carport structure?
- Yes, solar panels can be installed on a carport structure. In fact, carports are a popular location for solar panel installations as they provide ample space and can generate clean and renewable energy while providing shade and protection for vehicles.
- Q: I have 2 20 watt Solar panel. I have it hooked up to solar controller and batteries to inverter. Am trying to figure out how much watts am getting. I found the voltage but how do I find the amp reading on a mutimeter?
- It is possible your meter does not have the capacity to safely measure more than 300 milliamps which is too small to measure current output from solar panels. Assuming no losses in the system or components, if your meter does not have the capacity to measure 0 Amps, you will need to get one that does. Analogs are better than digitial for this. Most often the 0 Amp circuit of the meter has a discrete positive plug location for the positive test lead. Most have a common ground connection with the rest of the meter functions. If you are measuring current at the battery in the charge mode- Negative lead of meter goes to positive terminal of battery and positive lead of meter goes to the cable that was connected to the positive terminal of the battery. Since the Wattage is a nominal measurement, if you measure between the panel and controller, take measurement on one leg of the panel, as you want to measure the current with the loaded active circuit. Meter is oriented the same way as the measurement at the battery would be made above only this time the meter is between the panel and controller. At peak solar conditions, expect current to be measured at 2.5 to3 Amps or more per panel. Under optimal conditions your panel will have higher output than their ratings indicate. Open circuit can be close to 20 volts. Never short circuit the output of the solar panels. It is volts multiplied by amps that gives you Watts.
- Q: How do solar panels withstand harsh weather conditions?
- Solar panels are designed to withstand harsh weather conditions through their durable construction and protective materials. They are typically made with tempered glass or other strong materials that can withstand hail, snow, and heavy rain. Additionally, they are designed to be water-resistant and have proper drainage systems to prevent water damage. Moreover, solar panels go through rigorous testing and certification processes to ensure they can withstand extreme temperatures, high winds, and other environmental factors.
- Q: How do you make solar panels and do you need a lot of them to make electricity?
- it takes a ton of them to power a home most only put out 45 watts, [cheaper ones] solar is not cheap its more expensive than electricity
- Q: i've heard that solar panel batteries have to be replaced withen 5-0 years. how much do solar panel batteries cost? please include sources!
- solar panel batteries have many sizes. we can provide the price based on the power. in China it is 0.5625 dollar per watt.
