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.
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.
In contrast, a solar thermal collector supplies heat by absorbing sunlight, for the purpose of either direct heating or indirect electrical power generation from heat. A "photoelectrolytic cell" (photoelectrochemical cell), on the other hand, refers either to a type of photovoltaic cell (like that developed by Edmond Becquerel and modern dye-sensitized solar cells), or to a device that splits water directly into hydrogen and oxygen using only solar illumination.Application

- Q: i check the diodes in the backside of solar panels it reads out to be 0.433 each give me the same result but i was amazed when i check out the last two one which on clamp meter screen give me ''0L'' what this means? is that diode have malfunctions??is this reasons that the output of solar has been decreased?
- First of all, make sure that you are taking readings in the dark (with the solar panel indoors and covered). 0.433 is a reasonable forward voltage for a Schottky diode. Ideally, it diode should read open one way (possibly OL for your meter), and 0.4 the other way. If it's reading OL both ways, the diode is bad. You can either unsolder it or cut it out and verify that it is bad.
- Q: I have several 6v 4.5a sealed lead acid batteries. I would like to hook one of them up to a solar panel and have it stay charged from the solar panel all the time, but not overcharged. Is there a simple way to do this with an IC or something? I am only a beginner with circuits so I want it to be something very easy to make. Basically, I want it to stay charged all the time so it's available if I need it for a power out or something.Thanks.
- Yes, you can purchase a solar photovoltaic array to keep your batteries charged. You will need a Photovoltaic Cell Panel that produces 27 + watts (6volts x 4.5 amps = 27 watts) at 6 volts of electricity, a Charge Controller that allows only 4.5 amps of power through to the battery and will reduce the amps as the battery nears full charge and shut off the Panel when the battery is fully charged, and a 6v. Battery. Figure you will need a photovoltaic panel capable of producing a minimum of 27 watts if you are going to charge a completely dead 6 v. battery in one day. (with a clear sky). The way the system works is the sunlight strikes the cells on the panel and releases the excess electrons in the cells, they travel along central wires to your battery and charge the battery. When the sun sets, the procedure is reversed and the electrons flow backwards from the battery, into the photovoltaic cells. That is where the Charge Controller is needed. It acts a one way gate and lets the electrons go into the battery, but won't let them go backwards to the Panel. Just set your panel in the sun at the optimum angle for the season and your latitude on earth, connect the charge controller and then the battery, and it will keep your battery charged. Don't waste your money on the small wattage solar photovoltaic systems that claim to keep your battery charged. They simply can't do it unless your battery is in like new condition and is fully charged when they are hooked up. If you battery is a few months old, the small wattage photovoltaic systems can't keep up with the loss of power from sulfation inside the battery.
- Q: Can solar panels be installed on a telecommunications tower or antenna?
- Yes, solar panels can be installed on a telecommunications tower or antenna. This can help provide a reliable and sustainable source of energy for powering the tower's equipment and reducing its dependence on traditional energy sources.
- Q: Can solar panels be used in areas with high levels of noise pollution?
- Yes, solar panels can be used in areas with high levels of noise pollution. Noise pollution does not affect the functionality or performance of solar panels.
- 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.
- Q: How much space is needed to install solar panels?
- The amount of space needed to install solar panels varies depending on the size and quantity of panels being installed. On average, a single solar panel requires about 15-20 square feet of space. However, it's important to consider factors like panel orientation, shading, and energy requirements to determine the exact space needed for an installation.
- Q: I thought that I had a fairly good understanding of watt's law, but i'm starting to doubt myself.If I have a load of 4500watts at 240 volts, how many watts of solar panels do I need, if the solar panels are at 2v?Yes, Yes... I have a charge controller, batteries, etc...So the way I looked at this at first:watts = volts * amps For the load4500 = 240 * xx would be 8.75aFor the power source (each solar panel)00 = 2 * xx would be 8.3a8.75 / 8.3 = 2.25, rounded up = 3So... based on that I came to the conclusion that I needed 3 solar panels...But... then I was thinking. Does it work that way?Or do I need 4500 / 00 = 45, aka 45 solar panels?In other words...If I have a 2v power source, how many watts do I need to drive a load of 4500w at 240v?ThanksMatt
- The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.
- Q: I need a solar panel which can light up 4 full loaded 5 rooms appartment houses
- good idea going solar, i would suggest doing a google search, as their are many suppliers. then you need to calculate the amount of wattage you think these apartment houses are going to require. volts x amps = watts. if you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. you could even have a generator for emergencies if you go off the power grid. on final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. it will tie in to the existing electrical system in the apartments. i know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. the companies are profiting from this so i would suggest looking for a supplier in germany, first. they may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. i wish you success!
