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.
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: I need to use solar panels to charge lead acid batteries in an off-grid application. I understand that solar panels have a open circuit maximum voltage and an maximum amperage under no resistance, and that one can optimize the power output by regulating the load (resistance). If so, is just connecting 2 -volt solar panels to a lead-acid battery inefficient? Are there devices that will maximize 2 volt output power (by varying the resistance)? Am I on the right track here? Thanks for any help.
- Hi, okorder / having good batteries like this one make save you the hassel to buy controllers. You can control your own charge buy different tips
- Q: How can I start working as a solar panel installer/technician without years of education?
- With okorder for a review of a bunch of these. If you could produce and install these, at a much lower cost, it would be a viable business opportunity. You could be helping satisfied customers who wouldn't otherwise be able to afford it and you would be working in your choice of careers. It wouldn't cost much to produce these and you could require a large percentage upfront. Anyway, another avenue to explore. Good luck!
- Q: Am using 800watts sukam inverter and have 55watts panel. What controller can i use to connect my solar system to have a max power . Already i have 200 Amp/hr battery

- Q: Can solar panels be installed on carports or pergolas?
- Yes, solar panels can be installed on carports or pergolas. These structures provide ample space for installing solar panels, allowing them to generate clean and renewable energy while also providing shade and protection for vehicles or outdoor spaces.
- Q: I have a home made 24 volt electric cart. It is powered by two 2Volt deep cycle batteries. Since the motor runs on 24 volts the batteries are wired in series to produce the 24 volts. I only have a 2 volt battery charger, but I also have two 2 volt solar panels. It is a pain having to unhook wires, rewire it, or charge them one at the time.HERE IS THE QUESTION REALLY... Can I wire the two 2 volt solar panels together in series (ie: negative to positive) then connect it to the existing 24 volt system and have it charge the batteries fine. I know basic wiring, but I know nearly nothing about solar panels, will it work fine? will it cause them to break? or short out?(additional info, the solar panels are only rated at 5 amps so it will not overcharge the batteries or anything)
- Wiring the panels in series should be ok as long as they are exactly the same. Different impedance's could damage the panels. Remember that Voltages and Amperage's are indirectly proportional meaning that if you series your panels your voltage will rise but the amperage will be reduced.
- Q: I am designing a solar panel but i need to have maximum power output.How can i optimize the equation for power Total power=voltage * current to get maximum power.
- first place the panel so it is at right angles to the solar rays. Make sure none of the panel has any shade whatsoever. For best results use motor drives to keep it in that position as the sun moves across the sky. For overall maximum versus time, you need to be near the equator. Solar cells have a high internal resistance, so for maximum power transfer, you need a load of that same resistance. A good charge controller will use DC-DC converters to provide that load. .
- Q: Was at home depot today and a Solar City sales man came up to me, offering me free solar panels. He said he could install them on my garage for free, free installation, free panels. Promised me it wouldn't cost me a dime. This is obviously appealing to someone like me who has a $200.00 monthly electrical bill. Now my question is this. Is this a scam? Are there ANY hidden fees or things I should be weary of?- I understand I may not save tons of money, but if I can save even something as low as $20 a month I would be happy. I live in a sunny area and they seem very interested in my garage roof. Any information would be super-helpful, thank you.

- Q: Installing solar panels requires a big initial investment. Before I make this investment I want to check to see if the money I will save by installing solar panels will actually pay for this investment, in the long run. To calculate my savings, we should consider the area (square feet) I currently have available to install solar panels. Look at the available sunlight and its intensity in my state each month of the year. Based on this data estimate how much energy my solar panel will generate. Then compare that with how much energy (kWh) I currently consume based on my electricity bill.
- Your school spend $0,000 per month or per year?? Photovoltaic (Solar Panel) panels have a really large initial capital investment. If you live in a location (e.g. West Coast Desert, SoCal) where there are many sunny days so you might be able to break even quicker. Also note ,there are state and federal grants that can help ease the capital cost. Energy demand keeps going up so expect our current rates to double. People who have alternative forms like wind and solar will have the advantage when this time comes. Just think of when the US had it's oil crisis in summer of 2008, people with small efficient vehicles such as Prius's didn't feel the price increase like the people who bought cheaper large SUV's.
- Q: Can solar panels be installed on a building with historical significance?
- Yes, solar panels can be installed on a building with historical significance. However, it is important to consider the potential impact on the building's aesthetics and historical value. Careful planning and consultation with preservation experts can help ensure that the installation is done in a way that minimizes any negative visual or structural impact on the building while still harnessing the benefits of solar energy.
- Q: Do solar panels increase property value?
- Yes, solar panels have been found to increase property value. Studies have shown that homes with solar panels tend to sell at a higher price and faster than those without. Additionally, the potential for reduced energy bills and the positive environmental impact of solar energy can make a property more attractive to potential buyers, thus increasing its overall value.
