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:Infra-red solar panels?
Build okorder.com/
Q:Using solar panels to replace electrical wiring?
No. solar panels would not solve your problems and are usually not cost effective. Solar panels will not help to compensate for undersized electrical service. You would still have to upgrade the existing service. Once that is done you should have no problems and all the electricity you need would come from your power company. Have an electrician come out and do an inspection and tell you what all needs upgrading. Solar panels would save you money on the monthly power bill but the cost to install them would be higher than your savings. If it made economic sense to have solar power then everybody would be doing it. That's why you see very few houses with solar panels on top.
Q:Do solar panels shine/have luster? Please help me. Easy ten points!?
The problem with solar panels is that they often come with textured glass. This makes that the reflected light is scattered +/-0°. Therefore the 0.5° sun-disk small as it aprears in the sky will be blown up 40 times to a 20° reflection disk on solar panels. Find more information on zehndorfer.at/en/glaringsurvey Only a glaring survey can tell you exactly when and where you have to expect a dazzling effect.
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:what are the parts of a solar panel?
For a photo electric system you need 3 basic things. Photo voltaic Solar panels the quantity determined by you need and a charge controller for the cells they are rated by current. Batteries the quantity determined by your needs. Last an inverter to convert 2 volts DC to 20-220 AC. The size shown in watts is determined by you needs. If you plan to use it all the time you will have to have piece of equipment usually part of the inverter to sync the inverter up with the public utility and any power you don't use gets sold to the power supplier. That our a manual switch which will not allow you to sell unused power to the power company. If you are thinking about this do your home work and if possible contact it out. This is not a good first time DIY especially since you are asking this question. No offense. Otherwise you will need to do some reading and studying. But no matter what there are parts that an electrician will have to do by law and you may need a permit depending on where you live.
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:Are solar panels a good idea in Seattle Wa?
If you have southern exposure . Go for it.
Q:How to setup my home on Solar Panel?
good okorder.com lots of good ideas there
Q:time till a solar panel pays itself off?
I have a small system and do not make enough to sell back (no batteries) so it was less than 7 years BUT when you are talking about putting the initial in to a high yield div account and comparing it then I would say it took only 4 years to pay for because I was invested like many others with the capital it would have taken to get a large system and that investment LOST money while my solar pays for itself every year bit by bit. With systems now more efficient and rebates bigger and the investment alternatives not any better it is an easy choice.
Q:Why do glass covers improve the efficiency of solar panels?
Clear glass will allow most of the electromagnetic energy of sunlight into the air-tight volume of the solar panel. The light strikes the black coated metal tubes and the black coated backing, and is absorbed as heat. Part of this heat will radiate as infrared radiation, and much of this will leave through the glass. But a great deal of it will initially remain in the metal as heat. This heat will be partially transferred to the surrounding air, but because the glass stops the mixing of this air with the rest of the atmosphere, this heat will stay mostly contained within the solar panel. If the glass were not there, there would be a huge loss of heat into the surrounding air.
