1.The Description of Product

Nowadays, with the shortage of the energy sources, people start to develop the solar energy, a new long lasting sources of energy which can be used almost anywhere. Why solar energy become so popular, we summarized the below some advantages of solar energy.


CNBM Solar Polycrystalline Series




12 yrs free from defects in materials and workmanship

No less than 90% within 10yrs and no less than 80%   within 25yrs

TUV(IEC61215&IEC61730), CE, UL


 Photovoltaic/ solar/ green energy/ energy saving


1.High efficiency crystalline silicon 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. AI frame: Without screw, rner   connection. 6 holes on the frame can be installed easily.

5. Junction box: Multi function junction   box with water proof.

6. Long lifetime: ≥25 years; Less power   decrease.

7. Good performance of preventing from   atrocious weather such as wind and hails.

8. Resisting moisture and etching   effectively, not effected by geology.

9. The certificate issued by international   authority: UL, TUV, IEC, CE.

Q:Are solar panels efficiency already calculated in their power rate?
If it says STC or Standard Test Conditions on the nameplate or documentation, then that means 80 watts under bright sun at an unrealistically cool temperature. It is rare to see that power in real life, except when the perfect storm of conditions come together. There is also a PTC rating for some panels, which is more realistic. If the panel does not say STC or PTC, the manufacturer is free to make up whatever test they feel like, which generally leads to ridiculously overstated power. As for efficiency, for residential panels, that's generally only of academic interest. A 80-watt panel is 80 watts, regardless of the efficiency. A more efficient panel will take up slightly less space, but most people are more interested in the total price, since roof space is generally not an issue.
Q:Composition and function of solar panels
The demand for polysilicon is mainly from semiconductors and solar cells. According to the different requirements of purity, divided into electronic and solar level.
Q:How does Solar Panels works and what is the cost of getting a solar panel installed.?
They consist of a semiconductor junction which has an uneven distribution of charge so it has an electric field in it. When light hits the material, an electron is knocked off from its parent atom and can move around the material. The electric field pushes it in one direction, et voila. You have current! (it's most complicated than that, but it needs quantum physics to understand). In summary, light goes in and DC electricity comes out of the panel. To use it in your house you will need an inverter as well, which turns it into useful AC. Then you need a way of using up the extra electricity you produce when it's sunny but you're not using power Some people use batteries, most people use 'grid tied' systems, plug in to the national grid and sell electricity to power companies that you're not using! Unfortunately, without major subsidies (like those offered in Germany, Japan and soon the UK), solar panels aren't likely to be cost effective. In the UK it costs about £5-6,000 to install a kWp of solar power and it will make about £90 of electricity a year. In California it's sunnier, so would make about £200 of electricity a year, but it's still very VERY expensive without subsidy. On the plus side, technology is improving. Thin film technology can be done at half the price, so I'd say hold on until thin film solar cells go up for sale (right now they only sell them to companies for big projects). Prices should drop by at least half in the coming years if they can make enough to sell to households - and at that price it'll be worth it in places like California.
Q:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
Q:when building a solar panel should the diode be on the positive or negative side?
I'm assuming you're talking about the blocking diode and not the bypass diodes. Positive side.
Q:How can a solar panel work for me?
Yes, it can. Now what do you expect out of it? It can reduce your electric bill by some amount. That amount depends on how many solar panels you install and how sunny your days are. You have to pretty much cover a roof to get a substantial electric reduction. There are 2 companies where I live that have installed solar panels and covered most of their roofs with them. They've reduced their electric bill by about 30%. It's expensive to do this. Don't expect a fast pay back. In fact you may save more by using solar heating panels for hot water than by using solar electric panels. I think it's cheaper as well.
Q:Why do solar panels stop working?
If they get smashed, they won't work. Keep them clean, and they will last many years. I suppose there is a 'limit' to the effectiveness of the cells lifespan, but it must be more than 25-30 years. Just glass, metal frame and silica. No moving parts. Seems like a good deal.
Q:5kw Solar Panel Roof Kit?
Note that aiming is important - the sun is going to be perpendicular to the panels for only a few hours a year unless they are on an adjustable mount, so picking the time you most want power should be a factor in the angle they are mounted at - you can't keep the highest level of sun for summer into the winter time when the sun is much lower in the sky for a shorter time.
Q:information on solar panels?
A decent installation needs a solar engineer to make sure the panels are aligned to take advantage of all the solar it can get. that or You need to hit the books on solar radiation. online I would try different programs to get the feel. we get less solar radiating in the winter then in the summer. this needs to correctly compensated.
Q:making your own and installing solar panels. Bull s*** or not?
How confusing is this to do? Judging out of your question and rationalization which you posses no information or historic past in this section: Very confusing. Is it useful? no longer even remotely useful. high priced? confident, you will no longer stay long sufficient to make certain a ROI = return on your investment. Will I keep funds or lose funds? you will lose funds, equipped perfect the fee per Kilowatt will a techniques exceed what the electrical powered employer grants for you. If it replaced into elementary, useful, much less high priced and would keep funds you’d see those going up in all places. i understand a great form of very gifted human beings in this section ( consisting of me ) that could try this in a minute if ~ ~ it replaced into elementary, useful and would keep funds. If it’s a undertaking which you’d in simple terms choose to play with, decide for it. yet once you think of you’re going to keep funds, forget approximately it.
