Product Description:

 

Benefits of Solar Power:

 

Following to RMI, Balance-of-System (BoS) elements, this is, non-module cost of non-microinverter solar modules (as wiring, converters, racking systems and various components) make up about half of the total costs of installations.

For merchant solar power stations, where the electricity is being sold into the electricity transmission network, the cost of solar energy will need to match the wholesale electricity price. This point is sometimes called 'wholesale grid parity' or 'busbar parity'

 

Specifications of Mono Solar Panel

 

Average pricing information divides in three pricing categories: those buying small quantities (modules of all sizes in the kilowatt range annually), mid-range buyers (typically up to 10 MWp annually), and large quantity buyers (self-explanatory—and with access to the lowest prices). Over the long term there is clearly a systematic reduction in the price of cells and modules. For example in 2012 it was estimated that the quantity cost per watt was about US$0.60, which was 250 times lower than the cost in 1970 of US$150.

Real world prices depend a great deal on local weather conditions. In a cloudy country such as the United Kingdom, price per installed kW is higher than in sunnier countries like Spain.

FAQ

 

Q: Do you have the CE, TUV, UL Certification?

A: We’ve already passed all the tests, and any certificate is available.

 

Q: Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other

A: Actually we are only manufacturer of solar panels, but we could try to source them for you in China if you need. We could provide you an optimal system design to instruct you how to install.

Q: What is your warranty system?

 A: For c-Si panel: 25years output warranty for no less than 80% of performance, 10 years output warranty for no less than  90% of performance. Free from material and workmanship defects within 5 years.

For a-Si panel: 20 years output warranty for no less than 80% of performance, 10 years output warranty for no less than 90% of performance. Free from material and workmanship defects  within 2 years.

Q:solar panel design question?
Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
Q:solar panels vs (organic) plants?
Of course solar panels
Q:Need Help, 2v Solar Panel for Emergency?
You don't have much power to work with there. You could hook it up to a car battery to give it a sloooooow trickle charge. One amp will take like 60 hours of sunlight to completely charge a car battery. You'll be able to power small radios, ones that need nine to twelve volts or so. Just position the panel a bit away from the direct to the sun angle for your 9-volt radios, right at the sun for 2-volt radios. I would not try to power any AC adapters. You'd have to buy a DC to AC inverter, a very small one, and the inverter would steal about half the energy.
Q:how to make a solar panel?
In another building, workers weld solar cells together into strips, then align them by eye on a light box to form the rows and columns of cells that make up a complete solar panel.
Q:Solar Panels Have Faded?
Unfortunately Eileen the panels are bound to fade as its par for the course. Over time much like everything else (from an AC condenser to your knees and hips) everything starts to go south. When did you purchase and install your panels? If this was done within the past few years then something is definitely wrong, and you should have the manufacturer and installer come back and replace the panels....on their dime of course. Is the warranty on your panels still in effect? If so then its definitely something that they have to come back and take care of. There is a company I know of called Sun Electronics that has a 20 year warranty on their products, so if its worth anything you might want to buy your new panels/system from them. The panels around today are more efficient than those of years past, and with the cost coming down due to economies of scale and the tax incentives you might want to consider getting a new system. Sorry to let you down though Eileen!
Q:how many solar panels and what type to power a laptop computer that has to be plugged in when in use?
Solar Power For Laptop
Q:I would like to know mire about solar energy ?
There okorder.com. Building solar panels, none. There are internet sites where you can buy unframed panels to design your own. but you need a current stabilizer and possibly a power inverter to go with it.
Q:best value solar pv panel ?
Try now. It's much cheaper
Q:Solar panels for car fans?
You may not like it, but the answer's still the same. A car fan will draw anything from a few to several hundred watts, depending on which fan you're talking about (A/C, ventilation, cooling). A solar array will take up roughly one square meter to generate 00 Watts with the sun shining straight down onto it, so you'll need to cover (more or less) the entire roof (or hood) with solar cells in order to power that fan (minimum). If you still want to go ahead: Solar panels, Fuse, cables. Preferrably one cut-out diode per panel (in addition to the hopefully present internal diodes in the panels) in order to prevent one panle dumping its load into the next instead of into the fan. Much better option: get a low power fan (e.g a slow running computer fan) and connect it to that panel of yours. These fans make do with about 0 Watts (at a much lower air throughput), so you'll actually have a chance of running it from the solar panel without coverig your car in panels.
Q:cost of solar panels?
It all depends on where you live and who you get them installed by.
