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:Why do solar panels produce zero energy?
Solar photovoltaic panels are highly inefficient to begin with. There are a few possible reasons why it does not produce energy even in the summer . Wrong inverter is used 2. The angle of installation (azimuth and tilt) is not optimum to capture the sun Solar photovoltaic panels are expensive and inefficient, and will not survive in the long run.
Q:in a solar panel, where do the protons go?
silicon based photovoltaic cells used some boron as dopant. i dont understand if that helps supress proton pastime, the way they be conscious boron on supressing run away nuclear reaction.... im clueless as you
Q:solar panels on projectors?
Solar panels put out DC voltage, like a battery. The projectors that plug into the wall require AC voltage. Unless you got a travel projector that plugs into a cigarette lighter (does that exist?), you would need to convert the DC power from the solar panel to AC for the projector with an inverter. And if you want to use it when the sun isn't shining, you'd need batteries to store the power.
Q:how to power a 400 watt heater with solar panels and batteries?
Get the rating from the manufacturer, they will give you the watts per m2 of their panels. divide 400 into the rating and will have the total area, then get the area of the panel that physically fits better the project and divide the total area into that of the panel selected, you will have how many panels you need. For the batteries is more complicated because of the available light hours of your location and what time of day are you going to use the heater, to be safe make a bank of batteries to store 600 watts to have a 50% stored power for emergency
Q:how do solar photovoltaic panels work?
Hey E Girl, photovoltiac panels are pretty simple. They start with a solid block of silicone, and shave thin layers off of them, called wafers. Once you have about 72 of them, you take half of them and dope them with boron, then the other half are doped with phosphorous. Once that's done, they take one each phosphorous and boron wafer, and glue them together with a special conductive epoxy glue, and attach a wire to each wafer. When the two glued wafers are exposed to the sun, a reaction occurs that forces free electrons from the silicone particles from one wafer onto the other, and a voltage is generated between them, about /2 volt to be exact. Once all 36 pairs are glued together, they are wired in series, connecting the phosphourous wafer from one to the boron wafer on the next, and so on. If you start with 72 wafers, you'll have 36 pairs glued together when you are done. At /2 volt each, that makes a 8 volt panel, which is used to charge a 2 volt battery. The charging source always has to have a few more volts than the battery. These 36 pairs of cells are then arranged on some kind of back board, glued down, covered with acrylic glass and mounted in a frame. There are some great websites you can go to for more info, I will list some below. Did you know that there are over 00,000 homes and businesses in the US alone that use some level of solar power to operate their electrical systems? That's good news. We actually live in one of those homes, it is powered by both the wind and sun and heated with solar and wood. I hope this answers your question, good luck, and take care, Rudydoo
Q:How do you store energy using a solar panel?
Rechargable Battaries. You can get a wide range of them- which one you should use is depends on the capacity of your solar panel.
Q:DIY solar panels for Gride tie?
Congratulations on your solar panel. It takes a lot of work to construct one. Tying to the electric grid requires permission from your power company, and conformance to local building codes. This generally means compliance with the National Electrical Code (NEC), meaning your panels must be UL (or similar rating from another standard) listed, for fire and electrical safety reasons. Homemade panels won't qualify, unfortunately. I really would discourage you from trying to do a jungle installation without permission, as the power distribution in a house is nothing to be trifled with. That would also likely void your homeowner's insurance, and give the bank a reason to call your mortgage, if you have these.
Q:how do i build a solar electric panel for my home?
Homemade okorder.com
Q:A good brand of solar panels for my house?
Mitsubishi panels have served us well for 3 years so far, no problems. Kyocera had a well-known problem many years ago, but they lived up to the warranty and replaced defective panels. Their current products are considred good. I like the value delivered by Suntech panels. Might be a best buy - shop around. I have not heard about any of the major brands having trouble, lately. If you're intending to connect to the grid, be cautious about used or blemished panels. While they might work fine, they usually are ineligible for rebates.
Q:Why should I use solar panels?
well you can save money over time even though the initial costs are quite high. Solar PV will allow you to not be subject to electrical rate inflation, which is averaging at about 6% per year. Solar also is better for the environment, so it gives you piece of mind.
