Poly Solar Panel 310W B Grade with Cheapest Price


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.

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 our scientists making solar panels all wrong??
If the panels are deployed at outer surface of atmosphere then white will reflect the sun light to outer space. If the panels are deployed at earth surface, inside the atmosphere, most of the reflected light will be bounced back to earth by the atmosphere. For the solar panels we are talking about, they need to be dark color to absorb light and turn into electricity.
Q:cost of solar panels?
Try okorder.com
Q:How much do solar panels cost?
Go with Stephen's answer. It typically costs $20-40K for powering a home so I would go with $00K's. If that was a plan for your school, look into wind power. Your school would most likely have to place it outside of town but its all the same in the end.
Q:Solar Panels question?
I would suggest getting more info about solar panels, here's the stuff that could be helpful to you renewableenergyarticles.blogspot....
Q:How to charge a solar panel?
For the best answers, search on this site https://shorturl.im/awXJ0 The charge controller will protect the battery. You might want to think about getting a fuse.
Q:How much maintenance do solar panels require?
I'm okorder.com/... . That means that not only do they guarantee the panel won't completely die, they guarantee that it will deliver a certain amount of power. That suggests that manufacturers expect most panels to last longer than 25 years. Our panels have been up a little over 5 years - no trouble yet. In a dirty location, or where the panels are mounted flat, occasional cleaning may be required. In many place, the morning dew and slant of the panels is enough to keep them clean. In my limited experiments with our panels, I saw little difference in power production between a panel that appeared dingy to the eye, and one that was just cleaned. There is a component called an inverter used in most solar power systems. That generally has a warranty of 0 years, so expect it to break after 5, to be replaced at a cost of a few thousand dollars. Or maybe repaired for less. The kind of solar power popularly installed today does not use batteries. Batteries are generally only for remote installations that did not have grid power when the solar was first put up.
Q:How many LED's can power a solar panel?
The 40 kmcd rating is a measure of luminous intensity (how bright it looks), not a measure of output power of the visible light. We can estimate the performance of your proposed system as follows: The LEDs on OKorder each are rated about 20mA maximum at about 3.2V, or 64mW (milliwatts). If you use 470 ohm resistors connected to 2VDC, the current that will flow, per LED, will be about: (2V-3.2V)/470ohm = 0.0872A = 8.72mA The power taken from the 2VDC power source will be: P2v = 2V x 8.72mA = 224.6mW (per LED) The power input to each LED will be about: Pled = 3.2V x 8.72mA = 59.9mW (per LED) The LED has a luminous efficiency that can range from about 4.2% to 22%. This efficiency is the ratio of the amount of visible light output (in watts) divided by the input power (in watts). The OKorder listing doesn't identify the output power level (either in watts or in lumens), so let's assume a 0% efficiency. The LED output power will be about: Pout = 59.9mW x 0% = 5.99mW (per LED) A solar panel converts visible light to electrical energy with an efficiency that ranges say about 6% to 8%. Suppose the solar panel efficiency is 2%. Then the electrical power output by the panel will be about : Pe = 5.99mW x 2% = 0.72mW (per LED) If you shine 00 LEDs on the panel, the output electrical power will be 00 times that amount: Pe00 = 0.72mW/LED x 00 LED = 72mW <===ANSWER The power taken from your 2V source will be about: P2V00 = 224.6mW/LED x 00 LED = 22460mW = 22.46W The system efficiency will be about: Eff = solar output / battery input = Pe00 / P2V00 = 72mW / 22460mW x 00% = 0.32% SUMMARY: If you shine 00 of the LEDs on the panel, you will capture back about 0.32% of the energy expended, or regain about 72mW.
Q:What is the difference between monocrystalline & polycrystalline solar panels?
The polycrystalline solar panel has a longer life-span and has a higher efficiency. What this means is that from the energy that 'hits' the solar panel, more is caught and used to convert into electrical energy. A polycrystalline solar panel will have an efficiency of about 4%. The monocrystalline solar panel has a similar efficiency but the cells are prone to sunlight, so the efficiency drops over the years.
Q:solar panel for computer?
Yes. Basically, here's what you need (I'm keeping this general on purpose): The panels themselves -- how large an area depends on average power consumption and how much power you can get on average. That, in turn , depends on climate. You'd need more in Seattle than Tuscon, for example. I'd guess something in the neighborhod of 0 square feet. Depends also on haow many gadgets (printers, etc.) you have. You'll need a power storage system. Lithium gives you the best poser density (of off-the-shelf stuff) but an ordinary car battery works well and is reliable. And, of course, a control system to manage the power generation/storage/use so everything works together without that annoying smell that tells you you just cooked a few hundred bucks worth of equuipment! :)
Q:How would you build a Solar Panel that can convert Sunlight to Energy, just being on your house roof?
there is a website that sells a book for $40 thattells you how to do it cheaply check it out just google earth4energy
