About us
CNBM International Corp, established in 2004, is the business entity for trade and logistic of CNBM Group.With the advantages in Cement, Composite Materials, New Building Materials and Engineering, CNBM mainly concentrate on coal, steel and construction equipments and give priority to solar and wind energy development.CNBM International is highly recognized by its business partners and clients all over the world and has established good business relationship with the customers in over 120 countries and regions all over the world.

 

Mono-crystalline solar module is the core part of solar power systems, as well as the most important part of the solar system. Mono-crystalline solar module consists of high efficiency crystalline silicon solar cell, super white cloth grain toughened glass, EVA, transparent TPT backboard and the composition of aluminum alloy frame. The function of Mono-crystalline solar module is to convert solar energy into electric energy, or sent to the storage battery, or promote work load. The quality of the solar energy battery components and cost will directly decide the quality and cost of the whole system.

Q:Are solar panels affordable?
I don't think you can get a government grant? At least not just yet... But, you can get a nice Tax break for having installed solar panels on your home or for some their backyard works well. But, again you must be aware that having professionals install these panels can be quite costly. If you don't mind getting your hands a little dirty, tackling this project on your own isn't as hard as you might think! And you will be amazed at how much money you can save from the start. And if you get the family involved all the better! Building affordable solar panels for your home, is no pipe dream...But, you must be willing to do the work yourself! That's usually where most people fall short.
Q:Need Solar Panel Guru.....?
Yes and no. solar panels are expensive and inefficient. therefore the power you generate will cost many times what the same power from a power plant would, and therefore you generally can only run a few low powered things at once. Secondly they don't generate electricity at night so you need some means of storing the power. tht means even more efficiency losses. They also only generate DC power, so you have to run the power through an inverter to make 0V AC. inverters are notoriously inefficient and expensive as well, so now you've thrown even more power away converting it. Bottom line, you're gonna pay far more than $600 a month for these things and you won't get nearly the amount of power you think. it is generally a waste of money to do this in almost all cases. The ROI is usually well over 20 years before you break even.
Q:how many 45 watt solar panels would I need?
Lets say, for a simple approximation, that the 45 watt panel produces 45 watts /3 of the time and nothing the rest of the time. Each day, this will produce 8 hours times 45 watts = 360 watt hours. Also assume the battery charge controller and inverter waste half of that power, leaving 80 watt hours per day. If you use compact fluorescent lamps, that would allow you to burn 80 watts worth for an hour every day, or 90 watts for 2 hours, etc. That is a lot of light for a shed. You might consider using much less efficient tungsten filament lamps, but eliminate the inverter and choose low voltage (automotive) lamps that can run directly across the battery and lower the total cost, but give you only about half the light times time. The main advantage of the inverter might be that it would allow you to use small power tools or appliances in the shed. -- Regards, John Popelish
Q:do solar panels have to be in direct sunlight?
PV panels do not have to be in direct sunlight. If they are behind glass they need to be well ventilated to remove excess heat. If PV cells connected in series are not uniformly illuminated the series will produce an amount of power that is based on the light on the least illuminated cell. Thus moving a panel back from a window will mean that for large parts of the day it will produce almost no power as parts of the panel are shaded. This applies only when the cells are connected in series. In parallel they suffer no special degradation of production, but just the sum of illuminated cells. This makes a difference when you decide to use a higher voltage panel... high voltage panels are more susceptible to partial shading. But connecting low voltage panels in series gives that same degradation. Stay away from placing a panel back away from the window, or close to the edges of the window, under roof overhangs, trees and surrounding building shade, where possible.
Q:SOLAR PANELS (sun enerjy)?
First, solar panels come in two basic types - photovoltaics, which produce electricity (the black cells you normally think of), and solar thermal, which heats water (or some other fluid). It's one or the other, you could install both if you want that. Solar thermal is cost effective today, depending on how you currently heat your water. (The hot water could also be used to create electricity, like in a steam turbine, generally done in larger power plants). Photovoltaics are more expensive, but coming down in price every day. To know how many panels you need, you first have to determine how many kWH your house uses, and do you want to be completely off the grid (which would also require large batteries), or just reduce your electric bill.
Q:how do solar photovoltaic panels work?
Hey E Girl, photovoltiac panels are pretty simple. They start with a solid block of silicone, and shave thin layers off of them, called wafers. Once you have about 72 of them, you take half of them and dope them with boron, then the other half are doped with phosphorous. Once that's done, they take one each phosphorous and boron wafer, and glue them together with a special conductive epoxy glue, and attach a wire to each wafer. When the two glued wafers are exposed to the sun, a reaction occurs that forces free electrons from the silicone particles from one wafer onto the other, and a voltage is generated between them, about /2 volt to be exact. Once all 36 pairs are glued together, they are wired in series, connecting the phosphourous wafer from one to the boron wafer on the next, and so on. If you start with 72 wafers, you'll have 36 pairs glued together when you are done. At /2 volt each, that makes a 8 volt panel, which is used to charge a 2 volt battery. The charging source always has to have a few more volts than the battery. These 36 pairs of cells are then arranged on some kind of back board, glued down, covered with acrylic glass and mounted in a frame. There are some great websites you can go to for more info, I will list some below. Did you know that there are over 00,000 homes and businesses in the US alone that use some level of solar power to operate their electrical systems? That's good news. We actually live in one of those homes, it is powered by both the wind and sun and heated with solar and wood. I hope this answers your question, good luck, and take care, Rudydoo
Q:how does solar panels give power to the batteries?
solar panels work in an interesting way. light is absorbed by each solar cell, and light 'photons' bump into electrons to produce 'voltage'/power. the process is naturally called the 'photo-voltaic effect'. the loose electrons are captured by an electrical conductor in the solar cell (usually made of silicon) and a circuit is completed ... solar panels may generate more power than is actually needed. this extra power is simply stored in lead-acid batteries (they store upto 000 watts). read more about it here...

Q:How to make a solar panel at home?
It's not necessary. The time, materials, energy, and money you have to put out might not be worth it. Being this is your first unit, there are cheap enough panels; you should shop around. OKorder alone with an array of selections and there is Home Depot and others. When solar panels not hooked up correctly or you don't have the right equipment you can cause the batteries to explode. Do your research there's plenty on Youtube. I'd read the answers here but you really need to do some homework elsewhere. It is that serious that I wouldn't give any advise on the how to.
