Characteristics 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. .

Q:how much power do i need from my solar panels?
you must consider what electrical appliances you want to use, eg. do you have an electric stove? clothes dryer? air conditioner? heater? watts are watts, solar panels are used to create d.c. electricity which is stored in batteries then inverted to a.c. household electricity the d.c. batteries are usually 36 to 48 volts then this is converted to 20 volt a.c. when you figure out the watts being consumed in your household you size your batteries and inverter to these requirements. on your current electric bill you should see a charge for kwh, kilowatt hours= watts in thousands x hours. If you use 25 kwh per month your house is using 35 watts per hour x 720 hours in a month. you would then want sol.ar panels that charge at least 70 watts per hour because roughly half of the day it's dark depending on where you live December is even less of course in the northern hemisphere. Your batteries need to have capacity to hold a days worth of power, batteries are rated in amp hours, amp hours x volts = watt hours. I hope this points you in the right direction. All of this being said be sure to buy your system from a reputable dealer, someone with experience and good references. I am an electrician and have seen systems put in that are completely worthless because they were not sized properly and It sucks to see that someone paid $30k or more for something that is completely useless, it sucks even more when they ask me to help them and I say pay another $30k to up size the system to what they need. Remember you don't get anything for nothing so be prepared to spend money initially and be prepared to be live very energy conscious in your day to day life. Good luck
Q:I need help with solar panels?
Change the whole piece of solar panel, not just the glass. Looking for solar panel agent in your local city and get one.
Q:Which is Better: DIY Solar Panel vs commercial grade solar panel?
I would like to go with commercial grade solar panels.
Q:How can I power 5v or .08 amps in a remote loaction via solar panel.?
First things first. 5 Volts @ .08 amps would be .2 Watts. therefore you would need at least the same amount from a solar panel to replenish the batteries. But what puzzles me is the notion that plugging it in a wall outlet ? If you use 20 V @ 0.08 then the power consumption is 9.6 Watts And what is a meraki wireless repeater? I never heard of one. I'm a FCC licensed Ham and have some idea what is available. If you need 5 volts DC, you could use twelve Ni-cads in series and just keep them trickle charged with the solar panel That would make it compact. If you were to use an automotive battery (or motorcycle), then you would need a DC/DC converter.
Q:is it worth it to install solar panels?
In the state of Pennsylvania in the USA, a very basic 5KW solar installation will cost you $35,000. Of that you will recover approximately $28,000 over the next five (5) years between the State and the Feds. Making your net-cost something between $7,000 and $9,000 depending on various factors. All other things being equal in a standard household with fuel-based heat and window units vs. central AC, this system will provide roughly 50% of power required with a payback of approximately eight (8) years (with electricity at $0.4/kwh). The system has an estimated forty (40) year service life. Without _all_ the subsidies, the payback is longer than the estimated system life, especially if you consider the time-value of money. The life-cycle cost of a photo-voltaic array is horrendous. By that, I mean the total cost of producing the panels, installing them, and then removing them and disposing of them in an environmentally correct manner. All that added in and there is a negative payback. So, it all depends on what one defines as worth it. Putting the cost onto taxpayers via governmental subsidy to make an otherwise wretchedly expensive process viable may give you all sorts of warm-and-fuzzy feelings about renewable resources and reducing dependence on foreign oil and so forth. But the reality is that the true cost of solar panels exceeds that of nuclear power per KW delivered. Even today when nuclear plants start in the Billions-with-a-B in any currency you would care to name.
Q:where could i buy a cheap and low cost solar panel regulator?
investigate Tractor grant... they have been given small, medium and massive. Wal-mart additionally has infants for image voltaic lights... you ought to string them very close jointly to get volts up... i offered an merchandise which you defined as what you will make -- inexpensive fan with a image voltaic panel on it from Wal-mart--- it cools the interior my vehicle on sunny days.
Q:can a l.e.d light power a solar panel?
An LED requires an electric current to power it. A solar panel can most definitely power an LED, but LEDs don't store any power themselves. And solar panels aren't designed to be powered, they are designed to generate electricity. Rethink your premise from the start. It is as if you were asking if the electric wires in your home or community would be powered by the light bulbs and appliances you use.
Q:Solar Panel/Energy help?
The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
Q:How would you connect a solar panel to a fan?
Wire is always good. You may need some electronics to convert the voltage put out by the solar panel to what is required by the fan. Some batteries might be nice so that the fan will run when the sun is not shining.
Q:Solar panel for macbook?
an significant questions is what voltage output is the skill grant? what's the wattage while the laptop has been used for hours and then related to the charger with the computing device off? this often is the skill attracted to can charge the batteries. Your answer desires to be waiting to take action skill score. additionally thinking the fashion of Apple skill plug the relationship thoughts would be few. fold-able image voltaic panels + small 2 volt battery + inverter + Apple skill grant or fold-able image voltaic panels + DC to DC regulator for particular Apple computing device DC voltage which contains the recommendations-blowing plug and polarity. Can a internet-e book or pill or clever-telephone meet your vacationing computing desires? all of them use much less skill and could require much less image voltaic kit.
