product description

Strings of series cells are usually handled independently and not connected in parallel, though as of 2014)individual power boxes are often supplied for each module, and are connected in parallel. Although modules can be interconnected to create an array with the desired peak DC voltage and loading current capacity, using independent MPPTs (maximum power point trackers) is preferable. Otherwise, shunt diodes can reduce shadowing power loss in arrays with series/parallel connected cells.[citation needed]Multiple solar cells in an integrated group, all oriented in one plane, constitute a solar photovoltaic panel or solar photovoltaic module. Photovoltaic modules often have a sheet of glass on the sun-facing side, allowing light to pass while protecting the semiconductor wafers. Solar cells are usually connected in series and parallel circuits or series in modules, creating an additive voltage. Connecting cells in parallel yields a higher current; however, problems such as shadow effects can shut down the weaker (less illuminated) parallel string (a number of series 

The photovoltaic effect was experimentally demonstrated first by French physicist Edmond Becquerel. In 1839, at age 19, he built the world's first photovoltaic cell in his father's laboratory. Willoughby Smith first described the "Effect of Light on Selenium during the passage of an Electric Current" in a 20 February 1873 issue of Nature. In 1883 Charles Fritts built the first solid statephotovoltaic cell by coating the semiconductor selenium with a thin layer of gold to form the junctions; the device was only around 1% efficient.

The modules use high-quality imported polycrystalline or  Polycrystalline solar panel;

 Enclosed by high-rigidity tempered glass, with excellent light transmittance and output performance;

Surface treated with reflection-reducing process, increasing the light absorption.

Back sealed with anti-aging EVA, resistant from moisture and corrosion.

The efficiency of our  Polycrystalline solar cell is over 17%, and polycrystalline panel is over 16%. We stipulate, the allowance of each panel’s rated power has to be positive. Each panel is strictly tested before leaving the factory.

Our solar panel is designed with a lifetime of 25 years, and guaranteed that the power decline less than 10% within 10 years, and 20% within 20 years.

Q:Are solar panels efficiency already calculated in their power rate?
Solar panels are tested in a lab that has a light the produces 000 watt/hrs per square meter. In these conditions your panel will produce 80 watt/hrs. If you would like to know what it does in really world conditions you have to find the sun-hours in your given area. A sun-hour is basically how many watt/hrs hit a square meter in a day. This number changes based on time of year, orientation, and temperature. Here in Fairbanks Alaska if the panel was at 90 degrees facing true south in October (.9 sun-hours) It would produce 80 X .9 X .8 (20% efficiency loss due to wires and controllers) it would produce 273.6 watt/hrs on average each day.
Q:Properties of solar panel?
Q:Will my 8watt solar panel charge a car battery and how fast?
welcome to the wonderfull world of solar! you probably have a 2Vdc 8 Watt solar panel, to figure out its charging amps capability we do this equation Watts/Volts=Amps 8watts/2Vdc=.5Amps this is a conservative figure, since solar panel ratings are calculated using winter time sunlight, sunny locations and more daytime hours will give you higher amps. a typical good condition car battery is rated at 40Ah (Amp hours).to find out the charge time, we use the following formula; Amp Hours/Amps=T where T is time in hours 40Ah/.5A=26hours this is charge for a single battery, two batteries will double to over 52 hours. lets compare to charging a battery with your car, a car alternator puts out about 60 amps but usually run about half capacity. 40Ah/30amps=.3Hours! An alternator is far more efficient so charging with a small solar panel is best as an alternative or for low power applications. As far as using an inverter to power a TV, we can calculate how long the battery will last by using the original formula. a typical 9tv will use 70 watts 70watts/2Vdc=5.8A 40Ah/5.8A=6.9hours this figure is by drawing all the power from the battery, voltage inverters have a safety feature that will not let you discharge your battery all the way, so 40Ah battery will power a 9 tv for about 4.5 to 5 hours.
Q:What exactly is a solar panel?
Solar panels (arrays of photvoltaic cells) use renewable energy from the sun, and are a clean and environmentally sound means of collecting solar energy. Solar panels are a great way to generate electricity on a small scale. Solar panels are commonly named solar cells or photovoltaic cells. Photovoltaic means literally light electricity.” Solar cells or PV cells rely on the photovoltaic effect to absorb the energy of the sun and cause current to flow between two oppositely charged layers. Solar panel installation is a cost effective part of the green movement for saving energy. There are different types of solar panels available, including Monocrystalline Panels, Polycrystalline Panel, Cast Polycrystalline Panels, String Ribbon Silicone Panels and Thin Film Panels.

Q:Self build solar panel ?
Sure it is possible. There are even commercial products that do that. I have a solar cell phone charger. But it is not able to fully charge the phone battery. I am not sure why but I suspect the voltage it puts out is too low. In other words, it is a poor design. It is certainly possible to make a better design, but maybe not easy. You can damage a battery by over charging it, so just increasing the voltage is not the solution. You need just the right voltage and current.
Q:What home appliance can be powered by a solar panel?
Simple answer. Anything you can power with your normal household electric can be powered by solar. So you know what a solar panel is: A solar panel is more then one solar module mounted on a frame to be installed as a single unit into a solar array. Next question is normally what is a solar module: A solar module is a bunch of solar cells mounted together with a clear front and a white backing. Solar is something that you install on your home so you don't have to rent electric power from the public utility. It has a large upfront cost but will pay it's self and you then own something. Like if you rent a home you end up with nothing but if you buy a home you pay a big upfront payment and in the end you own it and can sell it for a profit. Yes you can run your A/C unit from Solar Electric. As said above. Anything you can run from the pubilc utility can be ran from solar. If it is in your home and running from electric right now you can run it from solar.
Q:Is it worth installing solar panels on a house that has no South-facing roof?
In your case you will need twice as many panels. This is because the panels on the west side of the roof will be in shade in the morning and the panels on the east side of the roof will be in shade in the afternoon, and a solar panel in the shade makes no power, or at least very little power. So right there you doubled the cost of an already too expensive system. Or you could build special stands to hold the panels facing south. It would be cheaper to just move to a house with better alignment!
Q:2V Solar panel directly to 2V inverter...and restult.?
2v staff
Q:Solar panel setup?
I hope you have some instructions. You need safety switches and fuses in the circuit. What voltage/currents are you running? Don't burn the house down or get electrocuted please. DC can be very dangerous.
