Product description
A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.[2] It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.
he 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 state photovoltaic cell by coating the semiconductor selenium with a thin layer of gold to form the junctions; the device was only around 1% efficient.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:I have heard a lot about solar panels and I want to know how these solar panels works and is it really possible to generate electricity using solar panels. And what is the cost of getting a solar panel installed?
- Solar okorder
- Q:Can solar panels be used in areas with high levels of dust storms?
- Yes, solar panels can still be used in areas with high levels of dust storms. However, it is important to ensure regular maintenance and cleaning of the panels to prevent dust accumulation, which can reduce their efficiency.
- Q:Are there any risks of fire associated with solar panels?
- Yes, there are some risks of fire associated with solar panels. While solar panels themselves do not combust, there have been instances where electrical malfunctions, such as faulty wiring or improper installation, have led to fires. Additionally, if a fire breaks out in the vicinity of solar panels, it can be more challenging for firefighters to extinguish due to the electric current flowing through the panels. However, when installed and maintained properly, the risks of fire are relatively low.
- Q:I read on CNN's website last year some company was creating a very cheap type of solar panel, that needs minimal maintenance and and has minimal glare from the sun. And the creator of the project said he one day wanted to cover every rooftop in the US with these solar panels. Seems like a good idea to me but I havent heared anything of it for a long time and I don't know what they are called... any help?

- Q:can anyone help me? i was thinking of installing solar panels to cut bills but would it be a waste considering its gonna need a circulating pump running almost 24/7 (which will use electricity) and even still will only provide me with quot;warmwater? also would it be possible to install the solar panels for the sole purpose of providing sufficient power to run electric heaters instead of using gas/oil? this way allowing me to have a warm house without the expensive bills. brobably talking about running 7 heaters/electric radiators.
- A thermal solar panel to feed your water heater is the most efficient. But you need a classic heater system too when there is no or little sun. Solar panels to heat a home is not at all recommended. First of all, you get less day light and less sun in winter, so you won't get much electricity. They work best in summer, but electric panels have poor yields and are a very long term investment. You will need to wait years before saving money. Natural gas, a well isolated home, and a good old sweater is the best way to cut bills.
- Q:Can solar panels be installed on a school or university campus?
- Yes, solar panels can be installed on a school or university campus. Many educational institutions are embracing solar energy as a sustainable and cost-effective solution for their energy needs. Installing solar panels on campus can help reduce electricity costs, lower carbon emissions, and provide educational opportunities for students to learn about renewable energy. Additionally, schools and universities can take advantage of various incentives and grants available for renewable energy projects, making solar panel installation an attractive option.
- Q:If you want to instal solar panels...how often do you have to replace them?
- I have several friends that have large systems down in Mexico where there is no electric grid. They have had these systems for years. They say you probably should plan on at least 0 years with decent output. The capacity does taper off with time so maybe half power in 5 years might be a good assumption. Here in Arizona our payback (Break even) point is about 8-9 years. Our state has subsidies along with fed, and utility company. A 3000 watt system will cost about $0,000 installed. That is about half off regular price.
- Q:Hi, i want to please a solar panel in Lima Peru, my Latitude is -2 and longitude -77. I understand that since i am in the southern hemisphere, my panel should be pointing north. However, i am using a program called pvdesigner, and according to this, y should face my panel with and azimuth of 00degrees (0 = south) and a tilt of 60degrees. Does this make any sense?thanks
- Typically, solar panels are installed facing the same as your latitude = 2 degrees to the North measured from horizontal. 60 degrees from vertical = 30 degrees from horzontal will give almost as much power in June as in December = beginning of Summer. You can face your panels straight up = zero tilt from vertical = better for December/ not so good in June. Usually, the same tilt as your North facing roof is best as it simplifies installation and reduces wind loading. Shade from trees etc will much reduce the power you get. Neil
- Q:I have a solar panel i got for free and I don't know what to do with it. Its kinda big at about 20x 0and it puts our 2 VOC / .23 ISC. I don't know of anything that I could use it for. Its too big to say charge a phone or ipod....any suggestions??
- Solar cells convert the energy of the sun into electricity. By using items commonly found in the home or your local hardware store, you can make a solar panel to demonstrate this photoelectric effect. You can also save energy by converting some of your traditional electrical supply over to solar power. Use sheet metal shears to cut the copper flashing in a square or rectangle to fit the size of the electric burner. Be sure to use a piece of copper flashing that is thoroughly cleaned. You may use sandpaper to thoroughly remove any sign of corrosion before proceeding. Place the copper flashing on the electric burner and turn the burner on. You will need to cook the flashing for as long as 30 minutes or more to develop a thick layer of black cupric oxide.
- Q:Can solar panels be used in areas with high pollution or smog?
- Yes, solar panels can be used in areas with high pollution or smog. While pollution and smog may reduce the efficiency of solar panels to some extent, they can still generate electricity in such areas. However, it's important to regularly clean the panels to maintain optimal performance.
