Introduction of Solar Polycrystalline Series
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 Solar Polycrystalline Series
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.
IVAI 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: Can solar panels be installed on theme parks or entertainment venues?
- Yes, solar panels can be installed on theme parks or entertainment venues. In fact, many theme parks and entertainment venues around the world have already embraced solar energy as a sustainable and cost-effective solution. By installing solar panels, these venues can generate their own clean energy, reduce their carbon footprint, and save on energy costs in the long run.
- Q: The voltage and power problems of solar panels
- Because the MPPT controller has a wider input voltage range, it can also convert multiple voltages into current charge and better protect the battery.
- Q: we are planing to move out of the grid. we need to operate constantly 2 laptops online - does any one can tell us how much solar panels we shall need to make sure of that?
- Create okorder
- Q: I know that one LED can't power a solar panel. I have found 40 kmcd LED's on OKorder. I know that several of them (28 totale each one with a 470 ohm resistor all at 2 VDC) can show a reflection on a wall in daylight 60 feet away..
- The 40 kmcd rating is a measure of luminous intensity (how bright it looks), not a measure of output power of the visible light. We can estimate the performance of your proposed system as follows: The LEDs on OKorder each are rated about 20mA maximum at about 3.2V, or 64mW (milliwatts). If you use 470 ohm resistors connected to 2VDC, the current that will flow, per LED, will be about: (2V-3.2V)/470ohm = 0.0872A = 8.72mA The power taken from the 2VDC power source will be: P2v = 2V x 8.72mA = 224.6mW (per LED) The power input to each LED will be about: Pled = 3.2V x 8.72mA = 59.9mW (per LED) The LED has a luminous efficiency that can range from about 4.2% to 22%. This efficiency is the ratio of the amount of visible light output (in watts) divided by the input power (in watts). The OKorder listing doesn't identify the output power level (either in watts or in lumens), so let's assume a 0% efficiency. The LED output power will be about: Pout = 59.9mW x 0% = 5.99mW (per LED) A solar panel converts visible light to electrical energy with an efficiency that ranges say about 6% to 8%. Suppose the solar panel efficiency is 2%. Then the electrical power output by the panel will be about : Pe = 5.99mW x 2% = 0.72mW (per LED) If you shine 00 LEDs on the panel, the output electrical power will be 00 times that amount: Pe00 = 0.72mW/LED x 00 LED = 72mW <===ANSWER The power taken from your 2V source will be about: P2V00 = 224.6mW/LED x 00 LED = 22460mW = 22.46W The system efficiency will be about: Eff = solar output / battery input = Pe00 / P2V00 = 72mW / 22460mW x 00% = 0.32% SUMMARY: If you shine 00 of the LEDs on the panel, you will capture back about 0.32% of the energy expended, or regain about 72mW.
- 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?
- kW is the unit of measurement used. kWh means you have kW steady for an entire hour. In the case of solar panels, say you are using 00W panels. That means at any given time assuming ample sunlight is hitting the panel, it is producing 00W. You wanted a kW so you will need ten panels at 00W (less or more depending on the rating of the panel) this will give you kW. That means at any given time you can get as many watts as needed up to kW (000W). Say the sun hits the panels for eight hours a day, you will have kWh each of those eight hours, or 8kWh per day. Unless you have a system of batteries to capture unused power, you will only be able to use up to kW (000W) at any given time, any unused power will be wasted. Solar panels alone are not like a generator, they do not slow down or speed up depending on demand. Even with no load on them, they will produce as much power as they are able, and without batteries that power is lost. To simply answer your question, if you get a kW system, that means kW per hour.
- Q: Can solar panels be installed in rural areas?
- Yes, solar panels can be installed in rural areas. In fact, rural areas are often ideal locations for solar panel installation due to the abundance of open space and sunlight. Solar energy can help provide electricity to remote communities, reducing their dependence on traditional power grids and improving energy access in those areas.
- Q: Do solar panels work with any type of heat or only sunlight? I have a bunch of little ideas floating around in my head and Id like to get them on paper but only if they really would work.Also does a concentrated amount of heat on one solar panel piece (quot;xor so) produce a higher or equal amount of electricity than a less concentration over a larger area?
- Last year here in the UK we had in my area snow most days quite heavy lays of it I noticed after clearing my solar cell panels in daylight conditions without any sun they were producing a fairly good voltage/amp ration, also as daft as it sounds in the middle of a January night with a good moon shin the snow refection produced a good electricity supply!. absolutely true.
- Q: Can solar panels work in the shade?
- They will work somewhat in the shade but they really work best in direct sunlight. I have solar panels on my home and just a cloud passing over will cause the output to drop quite a bit.
- Q: I have just made my first dolar panel 20 watts, charges my 27TMX Trojan battery perfectly. Now I am thinking to build more solar panels for a grid tie installation at my house, maybe 5 panels would do it, is this safe?
- Homemade okorder
- Q: My plans are building several solar panels and have a battery bank. I want to be able to power the refriderator and freezer and occationaly an electric grill. How would This work exactly and what would the best way to hook this up to make it work? I want to be able to convert DC to AC. How many batterys would I need to make this work. I know when Civil unrest happens I want to be prepared. How would Wind Power work If I can get the equipment I need?
- Solar panels and wind/water turbines all produce the energy and feed it into the batteries. Outfeed from the batteries thru an inverter to an electrical panel. From panel to outlets, into which you plug standard appliances and items. You can also get some appliances that run off of 2volt. Check with r.v. companies and suppliers for these. You can also run low voltage wires straight from batteries to switches to lights, fans, etc if you put in 2v ones. Just like your car has lights, fans (ac blower), and radio. As for how many batteries you need will depend upon how much ebergy you will use. You will need to figure how much all of your items use per hour. Then figure how long your charging device could be down for at a time. Solar panels will not charge at all for the 8-2 hours of nightfall depending on your area. Wind turbines will charge day and night so long as wind is of sufficient speed. Water turbines will charge 24/7 so long as water source(creek, stream, river) doesn't run dry. Neccessity/hr=N, time without charging =T. N times T = the amount of backup power you need to get you thru till charging sysytem kicks back in.
