Product description

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.

Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.

Q:I have tried researching on the internet and just cant find any real answer. I know that the amount of electricity produced when taking in the suns rays depends on the placement of the solar panels but I am just looking for ball park figures. Thanks: Ultimately it depends on your utility and the country you're in. In countries like Germany, Spain and the UK, the utilities will pay a higher price for the power you produce then what they sell it to you at. Otherwise, in countries that don't have such arrangements, net metering is best where what you produce is discounted from the amount you buy per month therefore so long as you produce less than you use, you get the full retail rate, otherwise you may get only half the retail rate with some utilities. Obviously, the solar panels are rated and won't produce much more than the rated power, a 4 foot by 2 foot panel would usually be rated at 00 watts but in most situations will produce about 80 watts and would probably cost about $500 US installed. If you assume 8 hours of usable sunshine a day, 70% sunny days, a 25 year service life, monthly billing and 0 cents a kilo watt hour retail rate, you can expect at most a -.67% per annum return on your investment, that's a negative sign out front. Basically without any subsidies, you will lose money on the panel, sure you're get some money every month, about $.34 per month for that 00 watt panel but it won't make back it's money at at a rate of 0.0 per kwh. With subsidies it might be a good investment but it's still not a good deal without subsidies.

Q:can solar power panels installed at home provide enough electricity to power house hold appliainces and heat water.: It will take about $44,000 to put enough solar panels to provide the same amount of power that you now have coming from a 220 v 00 amp power line to your house. You should also realize that you need some method of storage for use at night or dark days. This will add another $7,000 to the cost. The only real solution for the energy problem is nuclear power.

Q:i am very much interested in making a solar panel, my problem is where i can acquire the main components in order to build it, i am staying here in abu dhabi UAE i'm always searching on the internet for shops that can provide me a DIY kit but i did not find one, i need somebody who knows where i can get these things, please let me know.: Build okorder

Q:Are solar panels safe?: Yes, solar panels are safe. They do not produce any harmful emissions or pollutants during operation, and the technology has been extensively tested and regulated to ensure safety. However, it is important to follow proper installation and maintenance procedures to minimize any potential risks.

Q:Can solar panels be used for powering security systems?: Yes, solar panels can be used to power security systems. Solar panels convert sunlight into electricity, which can be used to power various devices, including security cameras, alarms, and sensors. This allows security systems to operate independently of the electrical grid, making them more reliable and cost-effective in remote locations or areas prone to power outages. Moreover, solar-powered security systems are also environmentally friendly, reducing reliance on fossil fuels and minimizing carbon emissions.

Q:Can solar panels be installed on a warehouse or industrial facility?: Yes, solar panels can be installed on a warehouse or industrial facility. In fact, these large structures often have ample roof space, making them ideal for solar panel installations. Installing solar panels on warehouses or industrial facilities can help offset energy costs, reduce carbon emissions, and contribute to a more sustainable energy future.

Q:What is the impact of roof color on solar panels' performance?: The impact of roof color on solar panels' performance is minimal. While a lighter-colored roof may reflect more sunlight onto the panels and potentially increase their efficiency, the difference is generally negligible. The key factors that affect solar panel performance are the angle, orientation, shading, and cleanliness of the panels, as well as the overall quality and technology of the panels themselves.

Q:If i took a lazier pointer and aimed it a solar panel would it take in the light. Also what types of lights would work on a solar panel like L.E.D, uv light bulbs.: If you mean a LASER pointer, then the answer is YES. However, the light is concentrated on a very tiny spot, so the panel will NOT generate much. Laser pointers are rated in milliwatts. A typical red laser pointer is rated at maybe 3 milliwatts. So, that is all that will be transferred at MOST. You don't get something for nothing, so the panel MAY put out 3 milliwatts from the laser pointer, but probably less since the solar panel is not 00% efficient. Solar electrical panels rely on sunlight over a large area measured in terms of many square FEET of area. As for driving lamps, the lamps do not care where the power comes from, only that the voltage and current are correct. Most bulbs will work equally well on AC or DC. Solar panels are used to charge batteries, and the batteries are used with an inverter to supply 0 VAC to things like appliances. What you CAN do is use a laser pointer to turn off a photoelectrically controlled light, such as a streetlight, maybe. Many streetlights have a photocell on top which looks at the sky and turns on the light when it is near dark until shortly after dawn. If you can shine a laser on the dome of the photocell, it MAY be bright enough to fool the photocell into thinking it is daylight and turn the streetlight off for a while...

Q:Can solar panels be installed on a swimming pool?: Yes, solar panels can be installed on a swimming pool. In fact, many pool owners choose to install solar panels to heat their pools and reduce energy costs. The panels absorb sunlight and convert it into energy to heat the water, extending the swimming season and making the pool more comfortable for users.

Q:Do solar panels work in cloudy weather?: Solar panels can still generate electricity in cloudy weather, though their efficiency may be reduced.
