Poly Solar Panel 280W B Grade with Cheapest Price


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:Solar Panel Help? Beginners?
Go with the 20W kit. Possibly he can get this going and light up a 5 watt bulb? Does he have an inverter? Sounds like fun! I may look into this later. I did notice that our interstate uses these small ones along the way for something. I have something more interesting; plans for a window solar panel box made out of most scrap items lying around. Just moved so have to unpack and find those plans! Anyway, have fun and hope your dad likes his kit.
Q:Increasing Solar Panel Efficiency?
Even the angle of a solar panel can increase it;s out put, if you point it towards the south, it will receive more light (or towards the light source if it is an artificial source) mirrors can also be place and angled around solar panels to gather and reflect more light to the panel, this is often done is solar water heating, but would work with a panel as well. Over all, solar panels are very efficient, it's our way of catching light that isn't.
Q:are there solar panel that work without the sun?
No. Solar literally means Sun. But...scientists are working on a panel that can absorb energy after the sun has set. It may be years until we see any commercial success.
Q:Has anyone had roof problems caused by rooftop solar panels?
Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.
Q:Electricity question about solar panels?
Watts = Volts * Amps Your heater needs at least 500 watts of AC power. The solar panel only produces about 200 watts of power ( 24volts * 8amps). Not enough to run the heater. Also, the solar panel produces DC current, not the AC current that the heater needs. However, if you had solar panel that produced enough power (watts), you could buy a transformer to turn the panel's DC output into the required AC output. But that doesn't seem like a real cost-effective plan.

Q:Why aren't electronics made with solar panels?
Solar panels could still be expensive, which would also raise the cost of the item.They also are made with chemicals that harm that enviroment(not too badly, but ya know..) You would also need to charge them, of course, in sunlight and most people enjoy the benefit being able to plug something in and still being able to use it. Not saying it's a bad idea, just the world we live in.
Q:New Prius; Solar panles a good design?
The solar panel option is for running a ventilation system while the Prius is parked outdoors, so the sun won't heat up the interior. Personally I think it's a good idea, especially if your car has leather seats-- There is nothing more unpleasant than getting into a car with leather seats that has been sitting in the sun for hours with the windows closed. Many a people in shorts have their thighs scalded on the leather seats that way. The solar panels are a luxury option, not standard equipment on the Prius. I think luxury cars like Mercedes and Cadillacs with leather interiors can use a system like that.
