Mono Solar Panel 20W A Grade with Cheapest Price
product description
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.
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.
Feature
The modules use high-quality imported polycrystalline or Polycrystalline solar panel;
Enclosed by high-rigidity tempered glass, with excellent light transmittance and output performance;
Surface treated with reflection-reducing process, increasing the light absorption.
Back sealed with anti-aging EVA, resistant from moisture and corrosion.
The efficiency of our Polycrystalline solar cell is over 17%, and polycrystalline panel is over 16%. We stipulate, the allowance of each panel’s rated power has to be positive. Each panel is strictly tested before leaving the factory.
Our solar panel is designed with a lifetime of 25 years, and guaranteed that the power decline less than 10% within 10 years, and 20% within 20 years.

- Q: Rooftop solar panel (not sure if rubber or plastic?) has leak arising from thin vertical crack in panel about long. Any ideas for repair?Thanks.
- Depending on the material and operating temperature of the panel, it MAY be possible to fix it very simply and easily by applying Hot Glue Gun adhesive over the cracked area. The high temperature glue gun adhesive melts at approximately 60 degrees Farenheit, and if the collector temperature does not quite reach, or exceed that operating temperature, then that repair method should work. Another possibility is an aerosol spray can product called LeakEnder. This is usually available at your local hardware store, or the major home improvement centers [like Lowe's, Sutherland's, Home Depot, McCoy's, etc.]. After preparing the area to be patched by cleaning, you just spray the LeakEnder patching material on the crack and an eighth of an inch or so around. IF the operating pressure or the collector is very low, it MAY even be possible to patch the leak with nothing more than a narrow strip of DUCT TAPE!!!!! Another possibility, but unless carefully accomplished is to weld the crack with a Soldering Gun and some scrap plastic from packaging material. The problem with this fix is that you must be very experienced in application of heat from the Soldering Gun, OR you will melt a larger hole in the collector tube than the crack was. Regardless of patching method, it is CRITICAL that the cracked area to be patched MUST be CLEAN and DRY BEFORE applying any patching material. Good luck!
- Q: Can solar panels be installed on a boat?
- Yes, solar panels can be installed on a boat. In fact, many boat owners choose to install solar panels as a reliable and sustainable source of energy.
- Q: We are considering getting solar panels for our home just south of Birmingham, AL. We know a little and are trying to educate ourselves the best we can. But we are having a hard time finding anyone around this area. We have done the yellow page thing, and some quot;green places around town. But to no luck.....
- Any electrical contractor could likely install them, and there are several Internet businesses that sell solar panels. You likely have no place there to get the kind of large panels you need for a house. Look at your local regulations. Your utility may not allow grid-tie, so you may have to set up an off-grid system with batteries and use separate wiring or a transfer switch. One thing a lot of people neglect is hail protection. In Birmingham, you're likely to have large hail (larger than golf ball size) every couple of years in the spring. You need to work out a way of covering them in advance of severe weather. Most panels will take up to golf-ball size hail with no problem. DK PS, I've done this myself, and have considerably more information. Email if you're interested.
- Q: Do solar panels require a specific orientation or angle for optimal performance?
- Yes, solar panels generally require a specific orientation and angle for optimal performance. The ideal orientation for solar panels is facing south in the Northern Hemisphere and north in the Southern Hemisphere to maximize exposure to sunlight. Additionally, the optimal angle of tilt varies depending on the latitude of the installation site to maximize energy production throughout the year.
- Q: Can solar panels be installed on a swimming pool?
- Yes, solar panels can be installed on a swimming pool. In fact, many pool owners choose to install solar panels to heat their pools and reduce energy costs. The panels absorb sunlight and convert it into energy to heat the water, extending the swimming season and making the pool more comfortable for users.
- Q: how fast does a 25watt solar panel generate power to a battery? trying to figure out a conversion factor here to get a rough estimate of how many i would need to power my house, please help?
- To figure our how many you need, take a look at your power bill. It will tell you how many kilowatt/hours you used during the month. My bill says I use about 2000 kilowatt/hours per month, or about 2000 kwh /30 days=67 kw/h hours per day. That is 67,000 watt hours. To supply that with solar panels, you have to generate at least 67,000 watt hours, but you don't have a full day to do it, since you have to do it while the sun is up. So you put the energy into batteries during the day, so you can use it at night. A 25 watt panel generates about 25 watts when fully illuminated by the sun. If you fully illuminate it for an hour, you get 25 watt hours. If you get 2 hours of sunlight a day, that would seem to imply that I need 67000 watt hours/25 watts /2 hours=45 panels. But for most of the day, the sun isn't hitting the panel fully, so it isn't going to generate the full 25 watts. When the sun is 45 degrees to the side, you only get about 70%. When the sun is 60 deg to the side, you only get 50%. And what do you do on cloudy days? And the shorter days in the winter? To make up for this, you have to increase the number of panels to make up for the loss. So in reality, I might need double this number of panels, for realiable solar power throughout the year. That works out to about 90 panels, or ,250 watts worth for my house.
- Q: Solar Panels not working very well, they have faded. Is there any paint or anything else I can do to restore them? Thanks Eileen
- Unfortunately Eileen the panels are bound to fade as its par for the course. Over time much like everything else (from an AC condenser to your knees and hips) everything starts to go south. When did you purchase and install your panels? If this was done within the past few years then something is definitely wrong, and you should have the manufacturer and installer come back and replace the panels....on their dime of course. Is the warranty on your panels still in effect? If so then its definitely something that they have to come back and take care of. There is a company I know of called Sun Electronics that has a 20 year warranty on their products, so if its worth anything you might want to buy your new panels/system from them. The panels around today are more efficient than those of years past, and with the cost coming down due to economies of scale and the tax incentives you might want to consider getting a new system. Sorry to let you down though Eileen!
- Q: how long till a 50 watt solar panel pays itself off in buffalo, ny if its $500. i have national grid and heres the link to the rates. i am residential.
- lots of info about solar panels, perhaps you'll find answer to your question renewableenergyarticles.blogspot....
- Q: If this was sold back to the grids what would be the profit i would stand to make per day on energy received in these panels? How did you come up with this answer?
- This question is too generalized to answer. Are you australia? If so ergon buys the power back at 45cents a KWH which is 3 times what they sell it for.(this is guaranteed for 20years) We have a 2.4kw system and it will take approx 5years to pay itself off. Once carbon trading is in full swing electricity costs are going to go up by 40%, then obviously it will take approx half the time.
- Q: How do solar panels affect the roof's structural integrity?
- Solar panels do not significantly affect the roof's structural integrity when properly installed. The panels are mounted on a rack that evenly distributes the weight, and professional installers ensure that the roof can handle the additional load. In fact, solar panels can even provide some protection to the roof by shielding it from the elements.
