Details Of Polycrystalline Solar Panel

 

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.

IV  AI 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. .

Product Description of Polycrystalline Solar Panel

 

CNBM Solar Polycrystalline Series (25W—310W)

 

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.

Q:thermodynamic question that includes heating water with solar panels?
Good points. I'm new to the solar energy world, but solar just makes sense. Who wouldn't want to make it work? The more I learn the more I think its a great alternative to some of the energy we use. This info really helps.
Q:How do you connect solar panel?
You need a charger Controller but 55 watt panel is not a whole lot of power. So yes you can buy a very good one but it will cost a lot more. For a 55 watt panel you only need a 4 to 7 amp controller. But why not buy a 0 amp so you can add a second solar panel etc... A PWM (Pulse Width Modulated) is the cheapest and most robust type MPPT (Maximum Power Point Tracking) These controllers actually detect the optimum operating voltage and amperage of the solar array and match that with the battery bank. The result is additional 5-30% more power out of your array versus a PWM controller So unless you have a system over 200 watt the PWM works very good I have two of the PWM myself
Q:Do they make solar panels like this?
Homemade okorder.com
Q:where does the solar energy go to when it hits the solar panel?
image voltaic panels take the ability from the sunlight's easy this is extra extreme than say a easy bulb and utilising the chemical homes of (i think that's a silicon and carbon based fabric) the fabric to rework the easy(yet no longer warmth) into electric powered ability. it could basically use very particular wavelengths this is why image voltaic cells are nowhere close to useful. oo i forgot the 2nd area that's maximum suitable to place nevertheless status cells to the place they are going to receive easy the final public of the day (distinctly the early afternoon) and that's as direct as achievable. so some distance as business form cells they are fastened on structures which turn them by way of fact the sunlight strikes around the sky so as that they receive the main direct achievable easy
Q:How much money does it cost to make ONE solar panel?
Have okorder.com . Possibly this could immediately instruct each and every one!
Q:What minerals are used in making solar panels?
Heating panels have aluminum for the frame, glass for the top, copper pipes running through them, and possibly some plastic parts. The raw materials are easily obtained. Copper is the most difficult to get probably, but it's not all that rare, since we used to make pennies out of it. A solar electric panel is similar, with the copper used for wires and interconnect instead of pipes. The actual solar cells commonly used are almost completely pure silicon, which is abundant worldwide. There are traces of other elements in the silicon like boron, arsenic or phosphorous - these are also inexpensive, and easy to get.
Q:How to charge a Battery with Home Electricity and Solar Panel together?
No, don't connect the panel directly to the battery. You need to isolate the solar panel charging output from the AC-powered charger. A couple of high-current diodes arranged with their anodes connected to the charging sources in the positive supply line will allow either the charger or the solar panel to lift the voltage high enough to charge the battery, albeit with about 0.6 volts dropped across the diode. Both cathode ends would be connected to the battery. This arrangement allows a positive current to flow from either or both charging sources at the same time, although in practice, one will generally be higher than the other. Also, if the AC charger's voltage is significantly higher than the solar panel, the charger may always charge the battery. You would need to regulate its output to be slightly lower than the solar panel when it's near it's minimum useful operating voltage. (note that the 0.6 forward bias voltage on the diode might prevent the solar panel from completely charging the battery if it has any voltage regulation on its output)
Q:what is one benifit in a solar panel?
In the UK, the only real benefit comes from the subsidies given to owners of solar panels. I believe the same is true elsewhere in the world. I suppose smugness might be a benefit though it is not justified.
Q:Feedback on Solar Panels?
Our solar electric system has been up for 5 years now. No trouble so far, and output has not diminished noticeably. They have survived gale-force winds (gusting to 00 mph) without loosening. If I installed the same system today, it would have been half the cost for the same power, and smaller, too. Can't say I have any regrets. It keeps up with our yearly electricity demand, but we live in a mild climate. We only turned on our heat today, and have no A/C in the summer.
Q:Best orientation for my solar panel?
It doesn't make sense to me. I am at latitude 37.7,and my panels face south at about 38 degrees. Yours should be pointed north as you suggest. Being so close to the equator, and in the absence of any better information, an angle of 2 degrees would be appropriate. However, choosing the best angle will greatly to your overall efficiency, so I would try to find a more credible source, How about the folks from whom you buy the panels. They would know precisely. By the way, if you haven't installed the system yet you might consider going to a high voltage system to cut known line losses in the conductors between the panes and the inverter, I did that plus increasing the conductor size over that recommended by the manufacturer. I gained about two percent in efficiency
