Solar Polycrystalline Series Panels
Introduction of Solar Polycrystalline Series 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. Monocrystalline 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.

- Q:How do solar panels affect the property's energy management strategy?
- Solar panels can significantly impact a property's energy management strategy by providing a renewable and sustainable source of electricity. By harnessing solar energy, the property can reduce its dependence on traditional power sources, lower energy costs, and decrease its carbon footprint. Solar panels can also help to stabilize energy prices, as they generate electricity during peak demand periods, reducing the need to purchase electricity from the grid. Additionally, solar panels can provide a reliable source of backup power during grid outages, enhancing the property's energy resilience. Overall, solar panels offer numerous advantages to a property's energy management strategy, promoting sustainability, cost savings, and energy independence.
- Q:i want to go off grid with solar panels but i need to know how many vots and watts i need to power my house
- you must consider what electrical appliances you want to use, eg. do you have an electric stove? clothes dryer? air conditioner? heater? watts are watts, solar panels are used to create d.c. electricity which is stored in batteries then inverted to a.c. household electricity the d.c. batteries are usually 36 to 48 volts then this is converted to 20 volt a.c. when you figure out the watts being consumed in your household you size your batteries and inverter to these requirements. on your current electric bill you should see a charge for kwh, kilowatt hours= watts in thousands x hours. If you use 25 kwh per month your house is using 35 watts per hour x 720 hours in a month. you would then want sol.ar panels that charge at least 70 watts per hour because roughly half of the day it's dark depending on where you live December is even less of course in the northern hemisphere. Your batteries need to have capacity to hold a days worth of power, batteries are rated in amp hours, amp hours x volts = watt hours. I hope this points you in the right direction. All of this being said be sure to buy your system from a reputable dealer, someone with experience and good references. I am an electrician and have seen systems put in that are completely worthless because they were not sized properly and It sucks to see that someone paid $30k or more for something that is completely useless, it sucks even more when they ask me to help them and I say pay another $30k to up size the system to what they need. Remember you don't get anything for nothing so be prepared to spend money initially and be prepared to be live very energy conscious in your day to day life. Good luck
- Q:I thought that I had a fairly good understanding of watt's law, but i'm starting to doubt myself.If I have a load of 4500watts at 240 volts, how many watts of solar panels do I need, if the solar panels are at 2v?Yes, Yes... I have a charge controller, batteries, etc...So the way I looked at this at first:watts = volts * amps For the load4500 = 240 * xx would be 8.75aFor the power source (each solar panel)00 = 2 * xx would be 8.3a8.75 / 8.3 = 2.25, rounded up = 3So... based on that I came to the conclusion that I needed 3 solar panels...But... then I was thinking. Does it work that way?Or do I need 4500 / 00 = 45, aka 45 solar panels?In other words...If I have a 2v power source, how many watts do I need to drive a load of 4500w at 240v?ThanksMatt
- The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.
- Q:I have a panel that quot;deep breatheproduces at 4% efficiency, what can it power, It's about 4ft by 2ft
- I also doubt your claim of 4% efficiency. That strength solar panel is brand new technology (this year) and is not available in retail sizes yet. You probably got duped by some false marketing... In any case; even assuming you had a 4% solar panel, there are too many things for us to give you an accurate assessment of the power production. Clouds, location on earth, season, angle of the solar panel; these are all things we need to know to calculate it. Odds are it should have the average rate it produces electricity written on the back panel or with the instructions that came with it. I know of no solar panel retailers that do not also offer free installation. You should get your money back or get that free installation (and then you never have to worry about how much power it has, it just gets you what it can).
- Q:how much energy or electricity a solar panel produces?
- That okorder / They helped me a lot when I was pursuing solar. They will provide you with a free solar quote and give you all the information you need regarding eligible incentives, a feasibility analysis, your estimated annual savings, payback period, and return on investment. All in all, they will be able to provide you with everything you need to know in order to make a smart decision. Good Luck!
- Q:What is the impact of snow accumulation on solar panels' performance?
- Snow accumulation on solar panels can significantly reduce their performance. The layer of snow acts as a barrier, preventing sunlight from reaching the panels and reducing their ability to generate electricity. Additionally, the weight of the snow can cause structural damage to the panels if not properly cleared, potentially leading to long-term issues. Therefore, it is important to remove snow from solar panels to ensure optimal performance and longevity.
- Q:How much space do I need for solar panels?
- The amount of space you need for solar panels depends on various factors such as the size and efficiency of the panels, your energy requirements, and the available sunlight. Generally, you'll need around 100 square feet of unobstructed roof space per 1 kW of solar panels. However, it's best to consult with a solar installer who can assess your specific needs and provide an accurate estimation.
- Q:What is the difference between on-grid and off-grid solar systems?
- The main difference between on-grid and off-grid solar systems is how they are connected to the power grid. On-grid solar systems are connected to the local utility grid, allowing excess electricity generated by the solar panels to be fed back into the grid and credited to the homeowner. This means that on-grid systems rely on the grid for power during times when the sun is not shining, such as at night or during cloudy days. On the other hand, off-grid solar systems are not connected to the power grid and operate independently. These systems typically use batteries to store excess electricity generated during the day for use during periods of low or no sunlight. Off-grid systems are commonly used in remote areas where connecting to the grid is not feasible or cost-effective. Overall, the distinction lies in the connection to the power grid and the reliance on it for electricity supply.
- Q:Can solar panels be installed on a multi-story building?
- Yes, solar panels can be installed on a multi-story building.
- Q:Can solar panels be used in areas with high levels of sand or dust deposition?
- Yes, solar panels can be used in areas with high levels of sand or dust deposition. However, the accumulation of sand or dust on the surface of the panels can reduce their efficiency over time. Regular cleaning and maintenance are necessary to ensure optimal performance in such environments. Additionally, certain design features, such as tilt angles and surface coatings, can be incorporated to minimize the impact of sand or dust deposition on solar panel efficiency.
