1.Structure of Solar Module Description

Solar panel refers either to a solar hot water panel, a common type of a solar thermal collector, or to one or more solar photovoltaics (PV) modules, electrically connected and mounted on a supporting structure.

A PV module is a packaged, connected assembly of typically 6×10 solar cells. Solar PV panels constitute the solar array of a photovoltaic systemthat generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 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, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Specification of  Solar Polycrystalline(270W-290W)

CNBM Solar photovoltaic (PV)module is designed for large electrical power requirements. It is the optimal choice for both on-grid and off-grid power systems. CNBM Solar panel offers high performance of power per square foot of solar array.Poly- or multicrystalline silicon(poly-Si or mc-Si): made from cast square ingots — large blocks of molten silicon carefully cooled and solidified. Poly-Si cells are less expensive to produce than single crystal silicon cells, but are less efficient. US DOE data shows that there were a higher number of multicrystalline sales than monocrystalline silicon sales.

Q:How long does it take to charge a 2v deep cycle battery with a 0 watt solar panel?
What is the open circuit voltage and voltage under load with the panel in full sun? Assuming it is typical of many 0W panels, the open circuit voltage is 2V and the voltage under load is about 7V. 0W/7V is 588mA. A typical car battery is 40 Amp Hours. Amp Hours, or Ah, is the capacity of the battery. How much current a battery can delivery starting a car is called cold cranking amps. A deep cycle marine battery will typically be more than 40Ah. A 40Ah car battery at 50% charge will more than likely start your car in fair weather. Cold weather is another story. So, to get a completely dead car battery to 50% - 20Ah - would be maybe two days of full sunlight - with only a 50% charge, or about 2.2 Volts. Not a great battery charger - however - It makes a great supplement, and can offset the use of DC powered equipment in the vehicle while the engine is off. Things like low-wattage lights, cell phone chargers, tablets, and the like will drain the battery down that much slower. I have a number of powered but low current items on in my truck all the time. A panel helps offset some of that drain if I don't drive for a few days.

There are lot of cheap solar panels today, Its all in the internet and most of them are made in China. Expand your knowledge and learn from a renowned solar company about the Cheap Solar Panels. Visit our site and contact us today!
Q:Solar Panels for Home?
We just recently had Pursol Solar Systems install some solar panels for our house. We got ours with no money down, found them online, and they happen to be in the same city where we live. Cool thing about switching to renewable energy is that you get tax break... government will actually pay for your solar panels! Also, YES ITS TRUE! You're meter will spin backwards because energy that's being produced that your not using, goes back to your energy provider (like selling it to them during peak hours)....
Q:Are Solar Panels worth it in Southern California?
Q:how does a solar panel works?
Kinetic energy of the solar photons in the 'light', hit the surface of the compound, displacing the molecular components in it, creating a flow of energy carrying corpuscles down the wire. These - collected at the end of this circuit - produce energy sufficient to cause movement via the magnetic fields they cross on the either natural or electrically induced magnets they pass through. Basic principles to have in mind, is that these panels only produce ONE type of energy: direct. From one side (+) to another (-), and you must follow this principle when connecting. My suggestion is find the supplier and get instructions. They usually have detailed information. In order to hook up this panel, you must follow instructions.
Q:2V Solar panel directly to 2V inverter...and restult.?
Those tiny inverters that plug into cigarette lighters are horrendously inefficient, as they assume you have the car's battery and alternator at their disposal. It's possible that the inverter itself needs 50 watts without even attaching a load at the output. Second, many 5-watt amorphous panels are too optimistically rated, and may only deliver 5 watts in the best sun. Given that, the inverter probably failed from undervoltage at the input. This is why there is always a battery connected. The idea is that the battery is charged over a long period of time by the panel, then discharged quickly by the inverter. The panel is probably fine. You can short the outputs, and generally nothing is harmed.
Q:SOLAR PANELS (sun enerjy)?
30 years ago when the Hippies shut down our clean Nuclear plants They promised a clean miracle. No such thing! I'm sad to say at best Solar will only provide a fraction of our energy needs. (I guess if one abuses enough drugs they'll think up anything?) I am an apprentice for a Electric foreman; we calculate $50,000.00 in panels will meet the needs of a k foot house. So you would need a hundred grand. You'd save 00 dollers a month in electricity, but you'd be paying ,000 a month to pay off your loan of 00,000.00 in panels. God Bless You indeed a nice thought if it was practical.
Q:DIY kit for solar panel?
Q:What is the principle of solar panels to convert solar energy into electricity?
Solar cells are a pair of light response and can convert light energy into electrical devices. There are many kinds of materials to produce photovoltaic effects, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium and other copper. Their power generation principle is basically the same, now the crystal as an example to describe the process of photovoltaic power generation.P-type crystalline silicon doped with phosphorus can be N-type silicon, the formation of P-N junction.
Q:Why did the voltage of a solar panel drop significantly after putting it through a step down voltage regulator?
you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
