Solar Polycrystalline Series Panels

Introduction of Polycrystalline Solar Panels

CNBM Solar photovoltaic (PV) Panel 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. Polycrystalline silicon(c-Si): often made using the Czochralski process. Single-crystal wafer cells tend to be expensive, and because they are cut from cylindrical ingots, do not completely cover a square solar cell module without a substantial waste of refined silicon. Hence most c-Si panels have uncovered gaps at the four corners of the cells.

 

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: I need to be able to charge a 2v 7amp battery with a solar panel. I understand that the charge controller will keep the battery from over charging/discharging, but what I don't understand is the amps.The solar panel is rated at 5watts.The solar panel comes with a 2v 3amp charge controller but will I need to buy a 7amp charge controller and replace it with that for my battery pack? Please explain. Thanks in advance.
If it is a charge controller that is wired between the panel and the battery only, then a 3A rating is ample. The controller only has to handle the maximum current that the solar panel can output. The panel will have (or needs to have) an open-circuit voltage that is greater than about 4V in order to actually charge the battery, whose terminal voltage will rise above 2V as it charges. The panel's open circuit output voltage typically is about 7V. The 5W rating is at the maximum power point under the illumination of standard sun and at a specified temperature. That maximum power point probably is around 4V, which means the panel will deliver the following amperage to charge the battery: I = P/V = 5W/4V = 0.36A Since 0.36A is well below the 3A rating of the controller, the controller will not be overloaded when charging the battery. Some charge controllers also have terminals for connecting the load that you want to power. If that's the case, then the controller also needs to be rated to handle that load amperage or higher. If you were to connect a 6A load, then you would like to have say a 0A controller. Hope that helps.
Q: Can solar panels be used in areas with high levels of rainfall?
Yes, solar panels can be used in areas with high levels of rainfall. Rainfall does not necessarily affect the functioning of solar panels as they primarily rely on sunlight to generate electricity. However, it is important to ensure that the solar panels are properly installed and maintained to prevent any water damage or reduced efficiency caused by excessive rain.
Q: I have a rental property and use a 230-Volt 6-Amp Pool Pump.I would like to use a solar panel to run it when the house is empty, using mains power when guests are here.The building is in the Caribbean so plenty of sun!!I wanted to run it quot;directand not use batteries. Is this possible??What size panel would I need? A DC invertor too??Thanks!!
Why don't you use the mains as the battery with net metering. That way you don't have to have two pumps, a DC pump for the solar and an AC pump for the mains. A 230 V, 6 A pump draws 3.68 kw. A typical solar panel produces about 400 watts so you would need about 0 solar panels which should run you about $20,000 US. Of course, you may not need to run the pump continuously but in order to use fewer solar panels for sporadic use, you would need the batteries or the net metering. Keep in mind that with the costs of the panels, you will be paying about 38 cents a kwh. Grid power usually costs around 5 cents a kwh.
Q: Is it possible to store energy from solar panels for night?
Solar Power At Night
Q: Solar panel packages have different levels of power. For instance you can get a kw system but is this kw per hour or day. How does this work?
it would be an instantaneous rating at maximum output. To get the the amount of power produced, you would multiply the number of hours at near peak output. kw X 5 hours = 5kwh or about 50 cents of electricity.
Q: Can solar panels be used to power an air conditioning system?
Yes, solar panels can be used to power an air conditioning system. The electricity generated by the solar panels can be used to run the air conditioning unit directly, reducing reliance on the grid and saving on electricity bills. However, the feasibility and effectiveness of using solar panels for this purpose may depend on factors such as the size of the solar panel system, the energy efficiency of the air conditioning system, and the availability of sunlight in the area.
Q: Can solar panels be installed on a university campus or educational facility?
Yes, solar panels can be installed on a university campus or educational facility. In fact, many universities and educational institutions have already embraced solar energy as a sustainable and cost-effective solution for their energy needs. Installing solar panels not only reduces the environmental impact of the facility but also provides an opportunity for hands-on learning and research in renewable energy for students and faculty. Additionally, it can help save on energy costs and provide a reliable source of clean energy for the campus.
Q: I'm wondering if the cost of the panels and equipment have come down enough to make them viable in areas like Seattle or Vancuver for example.
The key is the average insolation value for the location. This is a number that represents the effective numbers of sunlight available per day. The insolation for Seattle varies from 2.9 and 3.57, depending on who is reporting the number. The insolation where I live, near San Francisco is 5. For me, solar is paying off.
Q: What is the cost of installing solar panels?
The cost of installing solar panels can vary depending on various factors such as the size of the system, the location, and any additional equipment or services needed. However, on average, the cost can range from $10,000 to $30,000 for a residential installation. It is important to get a personalized quote from a solar installation company to determine the exact cost for your specific needs.
Q: hi guys, i need help, okay lets say i decide to put solar panels near a place where its inhabitated by people, what kinda of environmental factors should i consider? Will the solar panels cause any damage to the enviromnent around it? Will it affect the plant and animals around it? should i consider the weather? its for my class so if u guys can help thankx.
You would need to consider how much sun your area gets on average. You would need to do a cost/benefit analysis to decide if you will be saving money eventually. Environmentally, it would not affect the plants or animals around it, except those it might block the sun from. Meaning, the grass growing in the shade of the panels will probably die out, but that goes for anything that would cast shade for the majority of the time. Solar panels are simply rechargers for the batteries it's hooked up to. No different than a cell phone charger affects the area, people or plants around it. If it is a worry, make some orgonite and place it around the panels. :)
