Poly Solar Panel 285W 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.

Nominal voltage refers to the voltage of the battery that the module is best suited to charge; this is a leftover term from the days when solar modules were only used to charge batteries. The actual voltage output of the module changes as lighting, temperature and load conditions change, so there is never one specific voltage at which the module operates. Nominal voltage allows users, at a glance, to make sure the module is compatible with a given system.

Open circuit voltage or VOC is the maximum voltage that the module can produce when not connected to an electrical circuit or system. VOC can be measured with a meter directly on an illuminated module's terminals or on its disconnected cable.

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.

The basis of producing solar panels revolves around the use of silicon cells.[28] These silicon cells are not efficient enough in their current state and can only convert solar energy [29] in to usable power at a rate of roughly 10-20 percent.[30] In order for solar panels to become more efficient, and therefore more useful in the future, researchers across the world have been trying to develop new technology to make solar panels more effective at turning the sun in to energy.[31]

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:What Size Solar Panel Would I Need?
Solar in Chicago is not much help, you would need at least 3kwh for whatever size unit you have, (3 tons is meaningless in this context!) You would not get enough sun even in the summer to operate for more thn 6 hours a day. For Chicago you probably need a wind generator, or go for a heat pump.

Q:Can I hook up a Solar Panel to a car battery? Does it matter the kind of car battery?
well the thing to remember just like any rechargeable battery they don;t respond well to continues charging they need some down time to discharge and then recharge. during the charging process the liquid or battery solution get hot and even evaporates. Replacing the battery solution with water won't work when your battery has lost it's solution you need to get battery acid replacement or battery repair solution. this is sold in many location near where the batteries are sold. check your spec for your solar panel out put and take those specification to your local auto store and they might even suggest an over sized battery. you might consider adding an additional battery in series for additional power storage.you might also using a light sensor and cut off switch solenoid which which stop charging or which would also stop and current from returning back to the panel. if you have every own a small car the battery is much smaller than that of a pick up. be sure that you don't get the small battery look for a large heavy duty battery all sold in the same store.
Q:Solar Panels ????????
It means that it will deliver 00 watts of energy. Assuming correct voltages, etc. you could connect a 00W incandescent lamp and it will work just fine. So it is the instantaneous output of the panel. Storage is more typically measured in the watt/hour manner - identifying capacity rather than immediate availability. If you have 000 watt/hours of stored energy then you can run your 00W lamp for 0 hours - or two 00W lamps for 5 hours. See? It's simple.
Q:SOLAR PANELS (sun enerjy)?
First, solar panels come in two basic types - photovoltaics, which produce electricity (the black cells you normally think of), and solar thermal, which heats water (or some other fluid). It's one or the other, you could install both if you want that. Solar thermal is cost effective today, depending on how you currently heat your water. (The hot water could also be used to create electricity, like in a steam turbine, generally done in larger power plants). Photovoltaics are more expensive, but coming down in price every day. To know how many panels you need, you first have to determine how many kWH your house uses, and do you want to be completely off the grid (which would also require large batteries), or just reduce your electric bill.

Q:How to make electricity from the sun without using solar panels?
You can use mirrors to concentrate sunlight and boil water, but I don't know if that is cheaper. You'd need motors to keep the sunlight focused on the boiler. Or you could build a solar water heater. It doesn't generate electricity but it conserves the power an electric water heater would use.
Q:Is it truE thet solar panels. . ?
You do not need batteries unless you want power at night, you don't need a regulator unless you'll be using your panels to power anything other then what the voltage of the panels is (ie 2v panel = 2v llight bulb) 3.You can use them directly or you can use car batteries (though deep cycle batteries are better).
Q:What can a watt solar panel power?
New Mexico is a good area for solar. Unfortunately, solar electric panels generally don't save money over grid electricity until the installed system is large - like, 000 watts or more, 4000 watts being a common size. This costs many thousands of dollars up front, which hopefully are paid back over the years in electricity savings. There are a couple other things to look into, though. The first is conservation and efficiency. If you can shade and insulate your house so that the air conditioner doesn't run so much, that can pay for itself in a year. Also, NM is an excellent place for a solar water heater. Call a solar installer to see how much it would cost. That would pay back in a few years, with a much smaller investment than solar electric.
Q:Should we subsidize solar panels?
so, you think of that the perfect concept is to easily save specializing in oil and to not attempt to compete? each CON i've got talked to on right here is going on and on approximately how green power is a foul concept? yet, right this is China, with a centred purpose and fairly making it happen... ask your self how far we'd be interior the U. S. without the cons scuffling with us each step of how... how's that buggy whip enterprise going cons? that's what we recommend as quickly as we are saying owing to Republicans do you think of green power won't happen? China's already doing it... we are able to the two capture up, or supply up... and supply up has a huge unempmloyment value related to it...
