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.[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.
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 be able to charge a 2v 7amp battery with a solar panel. I understand that the charge controller will keep the battery from over charging/discharging, but what I don't understand is the amps.The solar panel is rated at 5watts.The solar panel comes with a 2v 3amp charge controller but will I need to buy a 7amp charge controller and replace it with that for my battery pack? Please explain. Thanks in advance.
- If it is a charge controller that is wired between the panel and the battery only, then a 3A rating is ample. The controller only has to handle the maximum current that the solar panel can output. The panel will have (or needs to have) an open-circuit voltage that is greater than about 4V in order to actually charge the battery, whose terminal voltage will rise above 2V as it charges. The panel's open circuit output voltage typically is about 7V. The 5W rating is at the maximum power point under the illumination of standard sun and at a specified temperature. That maximum power point probably is around 4V, which means the panel will deliver the following amperage to charge the battery: I = P/V = 5W/4V = 0.36A Since 0.36A is well below the 3A rating of the controller, the controller will not be overloaded when charging the battery. Some charge controllers also have terminals for connecting the load that you want to power. If that's the case, then the controller also needs to be rated to handle that load amperage or higher. If you were to connect a 6A load, then you would like to have say a 0A controller. Hope that helps.
- Q: Can solar panels be used to power a hotel?
- Yes, solar panels can be used to power a hotel. By installing a sufficient number of solar panels, a hotel can generate a significant amount of electricity to meet its power needs. This not only helps to reduce energy costs but also promotes sustainability and environmental responsibility.
- Q: Can solar panels be installed on sloped roofs?
- Yes, solar panels can be installed on sloped roofs. In fact, sloped roofs are one of the most common types of roofs where solar panels are installed. The angle of the roof can be adjusted to optimize the positioning of the solar panels and increase their efficiency.
- Q: Can solar panels be used in deserts?
- Yes, solar panels can be used in deserts. In fact, deserts are ideal locations for solar panel installations due to the abundance of sunlight and limited cloud cover. The open and flat terrain of deserts allows for efficient placement and alignment of solar panels, maximizing their exposure to sunlight and increasing energy generation. Additionally, the dry desert climate helps in reducing dust and dirt accumulation on the panels, which can improve their efficiency.
- Q: discription how does solar panels save energy
- I'm definitely no expert in the field but hope to learn much more in the future. I'm in the infancy stage of researching as many options as possible in the design and construction of a total green house. That being said, a particular local news story sparked my interest when they investigated the cost effectiveness of residential solar panel systems. Here in Austin, Texas, through subsidies and incentives offered, you can install a system that costs roughly 22.5k for about 7. Apparently these deductions come from a federal incentive (which is a very small portion) combined with those set by the city itself. Austin is a pretty progressive city so I imagine their incentives might be a little better than most but you can call your city's general info line (3) and do a little more digging. Another option you might have is renting the equipment. I was told yesterday that a company here in town would allow for the installation and use for a monthly rate. I know how tight cash can be in school and 7 thousand might not be tangible. The whole issue of energy conservation is so prevalent these days that new info is constantly coming out. Give your current energy provider a call and see what they can tell ya. I hope you find something that works for you. -G
- Q: I'm trying to charge rechargeable AA batteries with a solar panel. What guage wire should I use to connect the panel to the batteries? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size? My panel is 4.8V 50mA.
- You not only need a diode, but a circuit that opens the circuit if the voltage falls below a certain level. The diode is not the problem, but the batteries powering the solar panel when the voltage falls to low.
- Q: We want make solar panel for our home use. but we have no any right idea how we can make it. we want to make it with cheap prices.we also want to know the proper size of solar panel.where we can take help about making a solar panel
- How to Make a Solar Panel – Everything You are Going to Need There are several things you’re going to need when making a homemade solar panel, some of the main components include: Solar Cells Wood Plate Soldering Iron Solder Tabbing Don’t worry; special tools are not required for this DIY ‘solar panel’ project, and you will probably have everything you need laying around the garage. Now let’s go over the recommended materials for a basic solar system: Plexiglas Solar Cells Screws Lumber Jones Plug Wire Diode Caulk Silicon Material
- Q: I thought they were going to make solar powered cars and solar power plants among other things. It was only nearly 0 years ago that solar power was the big thing. Just curious, why did it die out?
- I saw a commercial the other night for a fan you hook onto the top of your car window, and it's solar-powered. (supposedly cools off your car while gone...as opposed to just cracking the windows some). Also, I've seen traffic lights and emergency beacons on the highway powered by solar panels.
- Q: Can solar panels be installed on a church or place of worship?
- Yes, solar panels can be installed on a church or place of worship. Many religious organizations have taken steps to embrace renewable energy and reduce their carbon footprint by installing solar panels on their rooftops or open spaces. Installing solar panels not only helps to generate clean and sustainable electricity but also serves as a visible symbol of the organization's commitment to environmental stewardship.
- Q: Why should I have a Generator if I have Solar Panels.....?
- Well the sun don't shine at night does it. Nor much on cloudy days. You either need a generator or a whole lot of batteries. The batteries are a pain to maintain, they're expensive to install and they have to be replaced periodically. Generator's probably a decent alternative. I'm sure most people just stay on the grid for their backup. Even better if you live in an area where you're allowed to sell back excess capacity. If you're looking to spend this kind of money anyway you could look at a household fuel cell that runs on natural gas. Awesome technology, though if you buy the unit all prebuilt and ready to go it's going to run you like 50,000 bucks.
