Introduction of Poly solar panels CNBM
Polycrystalline Solar Panels 235W With High Efficiency
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.
Feature
1.Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.
2.Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.
3.EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.
4.Long lifetime: ≥25 years; Less power decrease.
5.Resisting moisture and etching effectively, not effected by geology.
6.The certificate issued by international authority: UL, TUV, IEC, VDE, CE.

- Q: I have a 2 volt deep cylce Everstart battery with 845 cranking amps, and a Grape Solar GS-S-250-Fab5 250-Watt Monocrystalline Solar Panel . I use them to power a 48Flat screen TV, a Roku, my 65 watt consuming MacBook Pro, and a 65 watt Fan.I know from previous experience that just the battery, an inverter, and the fan, that the fan will blow for 0 hours straight.Should I really be concerned with a Charge Controller?
- Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.
- Q: if car companies install solar panels on cars, like in all the car were the sun can reach that would reduce the consumption of gas in the summer, and might save some energy for winter and if that energy is not enough they can use gas or electricity i think that would be a lot of savings, and less contamination i don't know that is my idea what do you people think?
- Yes. But you won't be able to go very fast. If you fill up the roof, hood and trunk lid of for example, a Toyota corolla, with the most efficient solar panels you can buy, you might get 2 hp in the mid day sun. That could push the car maybe 2 mph on a flat, and wouldn't get it up a hill unless it had super low gearing. In order to go fast enough on solar power to make it worth while, you need a large area of solar panels and a super light car. Like an aluminum tube frame with a foam and fiberglass composite body, skinny, high pressure tires and a solar array 6 ft wide by 2 feet long. A car like that, with good aerodynamics and a 6 hp motor could get up to 45 mph eventually, just slowly. But it's impractical because it's not safe to drive it with other cars around. But who says the panels have to be on the car? If you have a solar array that feeds as much power into the grid as you take out, that is essentially equal to being solar powered in all practical ways. Even if your car can't be entirely solar powered, that don't mean you shouldn't use solar panels. You could use solar panels in any car, to supplement battery charging, taking load off the alternator, and you would see an increase in fuel economy. There is a system on some cars that uses solar power to circulate air through the cabin when the car is sitting in the sun. This keeps the car up to 30 degrees cooler, taking a huge load off the air conditioner, so instead of pumping all that heat out, you simply vent it into the air, and there is an increase in fuel economy for a few minutes. Every little bit counts.
- Q: hi,i have 4 solar panels. I can get 9V 400mA when i wired them parallel. The question is: how can i make a regulator circuit to store power into batteries.
- wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
- Q: If my school uses 88240kWh of electricity per month and I have 000 50W solar panels running for 6 hours a day, does it mean it will take 88240kWh / {{[(50W x 3600s)*000]/000}kWh x 6} number of hours to generate that much electricity (88240kWh)?
- your first question: Does a 50W solar panel generate 540kWh? 540 kW-hr / 50W = 3600 hours it would take that long for the panel to generate that amount of energy. your second question is confused, as you both stipulate the number of hours at 6 hours per day, and you try to solve for the number of hours. 000 x 50w = 50 kW 50 kW x 6 hr/day x 30 day/mo = 27000 kW-hr/mo = 27 MW-hr/mo that is the amount of energy generated. That is nowhere close to 88240 kWh or 88 MW-hr. I would take 7 times more solar panels to generate that much energy. .
- Q: Hi everyone, I am a novice in solar energy system. I want to know if I am on the right track. Recently I bought a 30 W solar panel, 5 Amp controller, and a 22 Ah battery, how many watts and what kind of INVERTER do I need? I did an research some said 50 W and some said 300 W. And am I right on the 5 amp controller and 22 Ah battery to provide larger output of electric, or the higher the # the greater output for 30 W solar panel?Really appreciate for anyone who help!!!
- With a 30 watt panel, producing about 2 amps, your not going to have much power from that. A 22 AH battery will give you 2 AH of usage. A battery should never be drained below 50%. What this works out to be is simply Amp draw for 2 hours. Which equals to 2V light bulb that draws amp for 2 hours. Not much. Now to replace that usage with your 30 watt panel, provided the panel is clean and in max sunlight, it will take 6 hours. If you attach an inverter to your system for 5 Volt Usage then the DC voltage drawn from the battery is very high. Example: Say you use a 5 Volt component that requires 50 Watts per hour to operate. The inverter will draw 5 Amps out of the Battery every hour to operate that component. That gives you and /2 of use before the battery is down to 50%.. Maybe that will be enough to charge up a standard Laptop battery. I have 2 30 Watt panels that produce 5 Amps, 4 6V batteries that have 480 AH and a 25 Amp Controller with a booster that increase the amp output to 20 Amps per hour. I live full time in an RV and raise the panels to get max output when I am parked. This system provides me with all the 5V throught the 500 Watt inverter that I need. Good luck on you system.
- Q: How are solar panels installed?
- Solar panels are typically installed on rooftops or in open areas with maximum exposure to sunlight. The process involves mounting the panels onto a structure, such as a roof or frame, using brackets and screws. The panels are then connected to an inverter, which converts the direct current (DC) generated by the panels into usable alternating current (AC) electricity. Wiring and electrical connections are made to connect the solar system to the home or the grid.
- Q: Can solar panels be used in areas with high levels of electromagnetic interference?
- Yes, solar panels can be used in areas with high levels of electromagnetic interference. However, it is important to ensure proper grounding and shielding techniques are implemented to minimize the impact of electromagnetic interference on the performance and efficiency of the solar panels.
- Q: If you buy everything you need for a grid-tied solar set up, can you install it yourself or is it required that a professional installs it?
- Solar panels have to be installed by a professional in order to get the government rebates. Also the systems must meet state and local electrical codes. Most modern inverters will not turn on unless there is live power from the MAINS, so a ultility company is NOT required for any installation anywhere. There are plenty of electrical contractors and speciality solar contractors out there to help you to make sure that the system is properly designed with the correct components, properly installed, and legally certified. Also many states require a permit that may have a large fee before any installation and may not allow the homeowner, especially for city homes, so it is best to check first. You might be able to get away with it if you live in the country, but consider the safety as well. See if you can work with your contractor to get the materials that you both agree upon as well. They can help guide you based upon their experience. Also shop around for pricing as the panels are now going below $ per watt !
- Q: So I reckon it's time to install some of these bad boys. it's come to point where electricity providers are charging such extortionate amounts that I can definitely see these reaping huge rewards before long. (Okay I might be exaggerating a little - they are pretty costly themselves).The problem is I've read around that they're only fitted to south facing houses? Why so? Why can't they be installed on the rear side of the roof - the side facing the garden? My house is facing north, so the front door leads north. Could I have solar panels installed on the back? (That's basically my question, with a bit of a rant too lol).Cheers.
- You want the panels facing south because that is where they would get the most sunlight throughout the day. If your front door is facing north, then the back of your house would be facing south, right? So put them up in the back where they are facing south...haha wtf..
- Q: How do you know when it is a good deal to buy a solar panel. For example, what is a good cost per watt, how many volts should I expect, etc.
- first okorder / example: house roof is 20' x 20' 20' = 240, so sq. inches of roof is = 57,600 say rain fall for your area is 3 per month on average. 57,600 x 3 = 72,800 of rain collected. Using the conversion chart link above, that many cubic inches of water = 750 gallons of water free per month. Look at your water bill and see how much you use. Solar panels take on average 2-20 yrs to pay themselves off, just in time for them to be replaced. Paddle wheels go on for just about forever. We still find large paddle wheel mills in the USA that are over 200 yrs old, and still functioning.
