5.We ,CNBM ,has our own factory :CNBM JETION SOLAR .We can also customize according to customers' need . You can google our factory .

 

 

FAQ:Why install a Solar PV system?

There are many reasons to install a Solar PV system now:

As a low risk investment the returns of between 8-10% net are hard to beat especially during this financial downturn where bank interest rates are below inflation (i.e. money in a savings account even with interest added is actually reducing in value).

Its good for the environment. Installing a small domestic system of around 1.5 kW would provide around 1125 kWh of electricity every year, this would save around half a tonne of CO2 annually.

Electricity can be supplied at the point of use. Reducing strain on our national grid network.

The system will run silently and so will cause minimal disruption.

There is very little maintenance required for a PV system.

After the initial installation costs, there are no further fuel costs.

PV systems are modular, and can be added to at any time.

FAQ:How long will a Solar PV system last?

The MCS accreditation scheme means that all panels installed under the scheme by approved agents will continue to generate for at least 25 years. Over this time their output will diminish slightly but they should still perform at 85% at the 25 year mark according to the scheme rules. Manufacturers have invested heavily to ensure their products meet and in most cases exceed these target

Q:Why do monocrystalline silicon chamfer? Polysilicon film?
There are many single crystal chamfer.Single crystals are generally large chamfer, there is a single crystal process decision. There is a single crystal silicon rod is cut out, in order to make full use of the silicon rod, appear large chamfer; and polycrystalline is generally small chamfer, is to reduce the crack edge of the silicon wafer, the external stress of the silicon wafer or cell rupture. Polycrystalline battery will also appear large chamfer, those are generally small chamfer of the battery, found that there is a problem after the cut into large chamfer.
Q:What are the components of the solar street light
battery is generally placed in the ground or there will be a special battery incubator, can be used VRLA batteries, colloidal batteries, Iron-aluminum batteries or lithium batteries. Solar lamps are fully automatic and do not require trenching, but the poles need to be mounted on the embedded parts (concrete base).
Q:How long does it take to make a solar cell?
1-2 days.
Q:help understanding solar panel stuff?
Solar panels turn sunlight into direct current electricity usually at 2, 24, or 36v. You could probably have a very simple system with just a panel and a few dc fans assuming that: the panels never put out more power than the fans can handle, you don't mind the fans slowing and stopping when the sunlight fades. If you want the fans running more of the time, you will need the panel hooked to a charger that charges a car/marine type battery and the fans connected to the battery. The longer the wires, the thicker they need to be (and more expensive). If you want to use AC (alternating current like your house uses) you will need an inverter (which turns DC into AC). Each device and each section of wire loses power due to inefficiency (heat produced). Contact a solar company on line, in person, or learn more.
Q:What is the role of silicon wafer annealing furnace, what specific requirements
The silicon wafer contact material uses the quartz material, does not contact the metal material
Q:where can i get a small solar panel to power an outdoor water pump?
You will need more than a small solar panel to run a pump continuously, unless you don't mind that the pump only comes on during the day while the sun is out. st you need to know what the power demands are of the pump in question. Not only do you need to know the rate of the power draw from the pump, but you will also have to calculate how much power the pump will draw from your solar system every day. You will have to factor in that the sun doesn't shine brightly every day, of course there's also night, so you will need a storage battery, charging system to go along with your solar panel. Now most pumps like the one you described are 20vac. Most solar panels, the batteries, the chargers are 2vdc. In order to get 20vac you will need an inverter. Once again, you will have to make sure that the inverter you get can handle the demands of the pump. A solar system that actually works for you takes some carefull planning, it's not something that you can just hang from a tree. None of what I just descibed will be inexpensive by my definition, so if it were me, I'd dig a trench across the driveway, install some direct bury cable on a GFCI circuit out of my main power panel save a bundle.
Q:How to charge the solar lights
Solar panels open circuit voltage of about 4.5V, charge and discharge controller to detect the voltage after the action, the battery discharge to the lamp.
Q:Selling homemade solar panels?
Would those be heating panels, or electric panels? If the latter, you would not have any safety certifications (I assume), so the panels would be illegal to use for a serious, grid-tied system. You would need to make this clear to your customers, that they could only connect to stand-alone systems. If this is in the US, there is always some finite danger of lawsuits if your product is defective. If the water heater leaks or blows up on someone's roof, you might have to go to court to defend yourselves. Even if you disclaim all warranties, in some states, if you sell something as a water heater then it has to heat water reasonably, and also not be hazardous. In other words, fit for its purpose. Check your local laws.
Q:anybody got any info on solar panels for energy savings?
Consider calculating the solar costs and savings ahead of time. The price of panels have come down substantially in the last 2 months. Solar Panel lifespans have also increased. The return on investment also depends on your location in the world. Mains electricity costs seems to be going up quicker than inflation in Australia. Work out energy efficiency first as it usually cheaper than alternative energy.
Q:how the energy of solar panel measure?
Most PV solar panels are labelled with their peak power output - this is the maximum power (measured in Watts) which that panel can generate in full sunlight. Remember these simple formula- V=IR and P=VI The current flowing through load keep the flow of electrons and thus energy is produced.
