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.

Type

CNBM Solar Polycrystalline Series

Materials

Silicon

Guarantee

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

Descriptions

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:how to connect a solar panel to a motor?
You need a battery, no solar panel is strong enough to move any significant motor
Q:Need help with Solar Panels (FAQ's and opinions)?
Also crystalline silicon, but almost triple the power. I would suggest that you have a lot more research to do before just buying a panel. A single panel like that isn't immediately useful unless you have a device that takes exactly that voltage, and is not critical. A solar water pump might fall into that category. For anything else, you would need additional equipment, such as a battery, charger, and inverter. Even at these prices, a single panel is unlikely to save you money over the electric company in the long run, unless your electricity is very expensive. There is economy of scale, so larger systems can and do save money, at least for people located in the right place. If you have a remote cabin where there is no electric company, then this could be worth it.
Q:harbor freight solar panels ?
I bought my first set 8 years age and the 45 watt set finally gave up the ghost last week. I have another 45 watt set 3 years old and has maintained 4 2 v deep cell batteries at 3.5 to 3.8 volts for the last 3 years. I have them on my cabin and use them mainly for lights and TV. but with my 2000-4000 watt inverter runs the microwave nicely.
Q:installing solar panels on roof?
Biggest problem is availability of sunshine in the UK. Do you get enough to warrant the fuss or financial layout? Another problem is the orientation of your roof. Facing directly south, with a slope (in degrees) equal to your longitude would be ideal. As far as electricity goes, you have to be tied into the grid to take care of the times you are not generating all the power you need. When you are generating more than you need, you sell it but get paid at the rate the utility normally pays, a lot less than you would pay to buy from them. Still, it's something.
Q:best value solar pv panel ?
If powering a PC is your only goal, consider replacing the power supply in your PC with one that runs off native 2 volts (like the kind intended for RV's). Then you can avoid the 30% loss of energy in a cheap inverter.
Q:Hey. I need some help with solar panels and batteries :) Please see the detailed version beneeth :)?
One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .
Q:Question about home solar panel systems?
The $25,520 price amounts to about $8.5 a watt which is high, I would've expected between $2.50 to $5 a watt and those are dated prices so it sound like the vendor is raking the price up. You didn't mention how many months your $75 financing is for but keep in mind that at 3 kw for 8 hours a day for 30 days at 2 cents per kwh, you would generate $86.40 so you will be paying about twice as much for your solar power as you would had you bought the power from the grid. Mind you, for people on a fixed income, there is the security that the cost will not rise ( if properly insured ) so there could be an advantage to paying a premium for your power if you're on a fixed income. I'd say it's a rip off but I also believe solar has a ways to go even with subsidies before it's an economic choice and that's usually not a popular stance with the green washed crowds.
Q:Photodiode vs solar panels?
Yes, so are camera sensors. Except in cameras they're specially desgined to reduce noise.
Q:What are the main components of a solar panel?
Solar water heater consists of solar vacuum tube,water storage tank,supports and other accessories.solar vacuum tube is the key component of a solar water heatert,it absorbs sunlight and convert it to heat energy which heat water in the vacuum tube,hot water rises up,cold water fall down,such natural circution make water hot in the water tank.
Q:Everything about Solar Panels?!?
when you're in Malaysia, i'm no longer effective why you desire a heater, except perhaps a water heater. For that, use a photo voltaic heater right away. For the electrical energy, the most value-efficient thanks to do that's to stay linked to the grid, and offset your bill with photo voltaic. That way, you do not favor to oversize the photo voltaic for contingencies. there'll be compromise on your way of existence, each and every thing that plugs into the wall today will nevertheless plug into the wall and artwork advantageous.
