Muticrystalline Solar Panel 155W A Grade For Commercial 

Introduction

This is a kit using for factory and storage field. this product is a higher output version with stable power and we guarantee you for 20years.   

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.[2] It is 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.

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:Does making solar panels cause more pollution than they take away when used?
It depends on what type of pollution you are talking about. Some of the newer cells that don't use silicone are made with dangerous chemicals that are just dumped into the local water supply when made in China or other places with no real environmental controls. No matter how much carbon free energy the cells produce they will never clean up the mess people made when building them.
Q:Run a air conditioner off solar panel?
You can expect such an air conditioner to use something like 500 - 800 watts of power. The ET-P65420 20Wp solar panel produces at most 20 watts so you will need at least three of them. Since solar cells make DC (Direct Current) electricity, and air conditioners use Alternating Current (AC) electricity, you do need an inverter. The M20 is a 220 volt inverter, and I suspect you are looking at a window air conditioner that will probably use 0 volt power. And the M20 only puts out a maximum of 240 watts so you need one for each of the 3 or more solar panels you will have to use. So the first thing to do is shop for air conditioners, getting the most energy efficient model you can find, paying close attention to the voltage and wattage ratings in the owner's manual or on the UL label on the back. Say it is a 500 watt, 0V unit. You will need three solar panels and three 0 volt model inverters. Also note that the 20 watt rating of the solar panels if when the panel is facing DIRECTLY at the Sun. If you just lay them on the roof, then even if the roof is sloped at a good angle (30 degrees) and facing south, it will only produce the maximum power around noon. 4 hours before noon, unless to go up there and tip them up to face the morning Sun they will probably produce only about half that amount of power. So right there you either need a motorized mount to automatically follow the Sun or twice as many panels. However, if you are going to connect the solar panel(s) into the house power, so that it(they) merely supplement the power company power, then you can use any amount of panels, and the power company will supply whatever extra power you need. That requires a licensed electrician to do. Or if you want to just power the air conditioner directly from the solar panels without any interconnection to the house power, then you need to know a lot more about electricity that you appear to know.
Q:Why do solar panels burn out?
You can search on solar panel failure mechanisms for scholarly works. Amorphous silicon thin-film panels go through an annealing, and power drops off after a couple years. This includes most of those flexible rubber mat type panels. That's why those are not used on serious installations. Serious panels intended for rooftop service generally come with a 25-year warranty, suggesting that the technology is more reliable than your washer, dryer, TV, computer, dishwasher, or water heater. One brand of panel had trouble about 0 years ago, but the manufacturer replaced all that were turned in, even paying shipping both ways. It was a problem with that particular model, not the technology. Our polysilicon panels have been on the roof for 3 years, now, and I've seen no sign of wear, yet, either electrically or mechanically.
Q:Increasing Solar Panel Efficiency?
I am a senior in highschool and one of my classmates is basically a genius by all means that I can tell. He has already been accepted yo UNC Chapel Hill. His admissions statement was on exactly this subject. I proof read it for him. Anyways the basic problem with solar energy is that we can only harness about 20- 35 pecent of the energy and even less of that is converted into energy that can acutally be used. His argument is that if somehow we could harness chloraphyll which is the chemical which plants use to harness the suns energy and incorporate it somehow into our solar panels. We could harness up to 95% of the suns energy!!! Id deffinately look into this.
Q:Are our scientists making solar panels all wrong??
There are two basic types of solar panels. ) Thermal absorbers 2) Photovoltaics Thermal absorbers are black in order to convert sunlight to thermal (heat) energy. The whole idea is to capture all of the light with a dark surface, convert it to thermal energy and transfer the energy into your home for water heating or space heating. If you make the surface white or reflective, then the surface will absorb only a small fraction of the available light, hence the efficiency will be very low. In other words, the panel will not produce any heat. Photovoltaic panels produce electricity instead of heat energy. Photovoltaic panels are made from thin slices (“waffers”) of silicon with special coatings on the front and back surface. One of these coatings on the front is an antireflection coating to capture the light and channel it toward the silicon. Underneath the antireflection coating the silicon waffer is coated with other chemicals that convert the sunlight to electricity. The combination of these coatings gives the panel a dark color, usually blue or black. Here's the bottom line. If you want thermal heat or electricity from solar panels, the panels have to capture the light. When that light is captured, the surface appears dark because no light (or very little) light is reflected back to our eyes. It is not possible for a surface to be an efficient absorber, capturing all available light, and at the same time appear white or bright color or reflective to our eyes.
Q:Why solar panels are expensive?
Believe it or not, solar panels are so expensive in this country because of government subsides. Without market competition, companies have no obligation to compete with each other on price. If our government would stop paying people to buy solar panels and giving solar panel companies tax breaks, companies would be forced to lower their price and raise their quality in order to get you to buy their product. This would be true of oil/gas, corn, soy beans and a number of other companies and products as well.
Q:Does anyone know a company that will make custom solar panels?
okorder.com Other sources available on the first Link also. Wingman
Q:Should we subsidize solar panels?
I know for my friends that live out in the country in an off-the-grid house, it would cost a lot more to run power lines and buy into the coal-powered electrical grid than it does for them to own a few panels and batteries and use the passive solar design of their house. They also have a propane-powered stove and refrigerator and use a wood stove for heat when it gets below 0 degrees.
Q:Electricity question about solar panels?
A 500 watt water heater is very small. Most are over 5000 watts. But even a water heater that small would not heat water with a 95 watt solar panel. Inverting the 24 volt to 20 volt would still give you 95 watts of power. A little short of the 500 needed. Sorry. Solar is cool but not practical for large loads unless you install more panels.
