Mono Solar Panel 280W A Grade with Cheapest Price


Product description


60 cell multi-crystalline solar module. 40mm natural anodised frame. IP65 rated Jbox, 1m solar cable and a pair of MC4 connectors.TÜV SÜD,SABS ISO 9001:2008 certified.

There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

The problem resides in the enormous activation energy that must be overcome for a photon to excite an electron for harvesting purposes. Advancements in photovoltaic technologies have brought about the process of “doping” the silicon substrate to lower the activation energy thereby making the panel more efficient in converting photons to retrievable electrons.[13] Chemicals such as Boron (p-type) are applied into the semiconductor crystal in order to create donor and acceptor energy levels substantially closer to the valence and conductor bands.[14] In doing so, the addition of Boron impurity allows the activation energy to decrease 20 fold from 1.12 eV to 0.05 eV. Since the potential difference (EB) is so low, the Boron is able to thermally ionize at room temperatures. This allows for free energy carriers in the conduction and valence bands thereby allowing greater conversion of photons to electrons.

Product feather

solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.

A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricityin commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q:Can someone tell me about solar panels for homes?

Q:0W solar panel can use on what?
Graham is on the right track. However, you need to factor in a 80% DC to AC conversion loss. But yes a 0W CFL is about the size of it... Harbor Freight sells a system consisting of panels, battery, inverter, and TWO CFL's for $250. (You can power 2 CFL's off the grid for a very long time for $250)
Q:energy and solar panels?
It depends on the size of the solar panels and the intensity of the solar-light. So, there's difference in every place. It's impossible to answer unless there's detail of panel size, panel quantities, average rainfall, average solar days, etc.
Q:Solar Panel Question?
I like TBS0's answer, but 5KW isn't going to hack it. We don't live life on the average. If you turn on the oven, the dryer, the iron, a bunch of lights, and the TV, you are going to shut the system right down. You should not count on running everything with solar cells, but the most critical circuits. And you are lucky to have 25% of a day in optimum solar alignment for photocells. You need to think outside the Al Gore crazy box. Our modern way of life requires a lot of power! If you switched to coal or wood for cooking and heating and ironing, sunshine for drying clothes, heating the hot water heater, and for daytime lighting, then you could use the photocells for some lighting and the washing machine and anything electronic. You might stand a chance.
Q:how much do solar panel batteries cost?
solar panel batteries have many sizes. we can provide the price based on the power. in China it is 0.5625 dollar per watt.
Q:I will like set up a solar panel to cut down my eletricity cost in Cameroon.can you allocate me a supplier?
good idea going solar, i would suggest doing a google search, as their are many suppliers. then you need to calculate the amount of wattage you think these apartment houses are going to require. volts x amps = watts. if you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. you could even have a generator for emergencies if you go off the power grid. on final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. it will tie in to the existing electrical system in the apartments. i know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. the companies are profiting from this so i would suggest looking for a supplier in germany, first. they may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. i wish you success!
Q:Home solar electricity advice? Making the solar panels accessible?
Modern solar electric panels rarely fail. Because of this, if you would be installing them over a roof that only has a few years left on it, it would be better to redo the roof, first. In the unlikely event that a panel needs to be changed, this can be done in 30 minutes or so, because the panels are mounted on racks, with everything simply plugging together. I have never personally seen a solar installation go bad, but from what I hear, the inverter (a box that goes in next to your electric service panel) is usually what burns out after 5 years, assuming the install was done right in the first place. If you were to call roofers to repair your roof, they would somehow be able to get to your roof, by ladders, or a special truck. Solar installers use the same kind of equipment. They won't have a problem getting up there. A solar electric system is actually a very straightforward thing. No matter who installs it, if there is a problem, another installer should be able to diagnose and fix it.
Q:How about solar panels?
The power we get from sun's radiation is limited by the area we receive sunshine. One square meter will have kW power from sun's radiation. For current technology, the conversion efficiency is about 8%. So one foot by three foot of solar panel only produce 80Watt. This will not be enough for your application.
Q:Solar panels for security cameras?
Research using solar panels on stock tank water pumps. Same concept - you use a solar panel to power a remote something or other, only you would have to use a battery charged by day to run the camera at night. It does not look like you would need too powerful of a solar panel, the camera server says it needs less than 5w, no idea on the cameras, so check that out, but the whole system looks rather low power. You could easily get the necessary panels, maybe the battery too, for... I would say $200 (not in one package, you would have to get separate things). Connection of everything would be simple, no electrician needed (but keep that to yourself, depending upon state rules and regs).
Q:Are photovoltaics to do with solar panels?
Solar panels are a generic term for any type of solar collecting panel. There are two major types: Photovoltaic uses substances that turn the incoming radiation directly into electricity. Usually you have to have direct sunlight (no clouds) for this to work well. Solar thermal is also used in a lot of areas. Here the radiation is used to heat a circulating fluid (often water directly), and then that is either used directly, or it's used for heat exchange with a heat pump or a boiler system. Solar thermal can collect significant heat even on a cloudy day. So a solar panel could be made of photovoltaic panels, but it doesn't have to be.
