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: Are solar panels safe?
Yes, solar panels are safe. They are designed and installed to meet strict safety standards. They do not produce any emissions, and the risks associated with solar panels are extremely low. However, it is important to ensure proper installation and maintenance to maximize safety.
Q: Ok so i can have a problem i have two 5 watt 2 volt solar panels a 2 volt battery and a 400 watt ac 2 volt dc inverter i believe im only getting 5 watts from from my solar panels thats the equivalent of one is there any way i could get full voltage from my solar panels without theoretically burning my wallet.. please help
I think you need to take some basic courses on electricity. Usually, 8 volt solar panels are required to charge 2 volt batteries. The voltages of photovoltaic cells are set by the material they are made of, only current changes. If you hook up a 2 V solar panel to a 2 V battery, no current will flow, nothing would get charged. You would need some elaborate DC to DC voltage converters to charge a 2 V battery from 2 V solar panels. Solar panels can be connected in parallel or in series, as you've made the mistake of buying 2 V solar panel, you would have to wire them in series and have a charge controller that could limit the voltage of the charge. Did it ever occur to you that two 5 watt solar panels would not be able to provide the power needed by a 400 watt inverter? You're just running off your battery with your set up. Solar power is expensive power, you can not have solar without burning a hole in your wallet.
Q: i have a calculator with a solar panel what could i power with it? like could i hook it up to a psp even though it will take forever to charge? and how would i do this?
take a look at the back of the psp, most rechargeable things have technical specifications for what kind of charger to use, like the voltage, the amps, and the wiring
Q: What Are Solar Panels Made Of?
Silicon. They have to compete with computer chip makers for the same supply of silicon. As solar panels are becoming more common, the price of computer chips is going up.
Q: Can solar panels be installed on forests or protected areas?
Solar panels can be installed in forests or protected areas, but it should be done with careful consideration and planning to minimize the potential negative impacts on the ecosystem.
Q: Can solar panels be used in areas with high levels of lightning activity?
Yes, solar panels can be used in areas with high levels of lightning activity. However, it is important to install proper lightning protection systems and grounding measures to minimize the risk of damage or electrical surges caused by lightning strikes.
Q: Can solar panels be used for powering a concert venue or entertainment center?
Yes, solar panels can be used to power a concert venue or entertainment center. By installing a sufficient number of solar panels, a venue can generate clean and renewable energy that can be used to power various electrical systems, including lighting, sound equipment, and air conditioning. This not only helps reduce dependence on fossil fuels but also lowers energy costs in the long run. However, the feasibility and effectiveness of using solar panels for this purpose would depend on factors such as the size of the venue, its energy requirements, and available sunlight in the area.
Q: Can solar panels be used for powering a mining operation?
Yes, solar panels can be used to power a mining operation. Solar energy can be harnessed to generate electricity, which can then be used to power various equipment and machinery required for mining operations. The solar panels would need to be properly sized and installed to meet the energy demands of the mining operation, taking into account factors such as the required power capacity and the availability of sunlight in the location. Additionally, energy storage systems may be necessary to ensure a consistent power supply, especially during periods of low sunlight.
Q: Can solar panels be installed in a shaded area?
Solar panels can still be installed in a shaded area, but their efficiency will be significantly reduced as they rely on direct sunlight to generate electricity.
Q: lately i have been interested in solar power. i own my own home and in Texas it's HOT, so my A/C is always on and that light bill is like $300.00 a month. i was looking at other light companies but then i remembered that there are the so called solar power but i dont knowknow to start or how it would work to power the a/c machine...pls help
Solar panels are a great way to cut back on your energy bill. Once you are hooked up to solar energy, the home owner does absolutly nothing different than if you buy electricity from the power-company. Sinse you live in texas, it is more than likely you will not be able to use purely solar power to meet your energy needs unless you purchase a large system ($30,000+). However with enough of an investment, you can 'Sell' your energy back to the power company and greatly reduce your electric bill. I would call a licensed Solar Power company for more information if you do not know much about solar. While the system is relativally simple, it should only be designed and installed by trained licensed professionals.
