Mono Solar Panel 3W A Grade with Cheapest Price


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 know absolutely nothing about electronics but have a lot of money. I am thinking of buying the Sunforce 3730 30W monocrystalline solar panel (the best I could find that was that size or smaller). What would be a good battery to go with it? I am thinking of buying a 2V Concorde Sun Xtender (again, the best I could find). But how many batteries will I need? I want enough batteries that it would take the solar panel 2 days to completely charge them from empty (bearing in mind the unavoidable inefficiencies like cloudiness/changing sun angles). Also, what other stuff would I need, like I hear something about a quot;charge controllerquot;? Any suggestions would be appreciated.
If you are at a location/time where the panel will put out less power, you can adjust the battery size accordingly. And running a battery to empty is very bad for it's service life, so it's better to go a bit bigger.
Q: I want to make 2V 4.5A solar panel to charge my battery used in my RC car project. I just like to know how should I amplify the current for 4.5A. I need the total circuit diagram. Can anyone help me. Please. I need some affordable methods please.
To increase current, you connect the cells in parallel. But I think you really mean you need 4.5 watts rather than 4.5 amps of current. For an RC car, 4.5 amps would be huge, literally a regular car battery. So I think you mean you need a 2v, 4.5w panel. That would make more sense for an RC car battery. I went on OKorder and bought a 2v, 5 watt panel for about $30.
Q: Can solar panels be installed in shaded areas?
Solar panels can be installed in shaded areas, but their efficiency and power output will be significantly reduced compared to panels installed in direct sunlight.
Q: I'm doing a project for school and I'm a little confused about energy and solar panels. I'm looking to propose installation of solar panels to power the computer lab at my school. From what I've read a computer and monitor use roughly 350 watts per hour. I was looking at solar panels and it says they produce various wattage. For example, I was looking at one rated at 200 watts. Does that mean 200 watts in a day? Or per hour? Please help.
The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
Q: I want to be more green and if I get the panels will I still have a regular electric bill?
The most cost-effective solution, which the vast majority of new installs use today, is solar alongside the regular power company. That way, you need no batteries, and if the solar array isn't producing enough at any given time, you draw from the electric company. When the array is producing more than you need, instead of just throwing that power away, the power company buys it (usually). In short, yes, you will still have an electric bill, but a smaller one. On our house, the electric bill was a little less than $5 a month, with an end-of-year settlement of an additional $2. How much does it cost? Unfortunately, that's like asking how much personal transportation costs. Some people need a van to transport the kids to soccer, some may get by with a motorcycle, others may need only a bicycle. The best thing is to contact a professional installer to get a quote based on your location and electrical usage. Solar electric does not make financial sense in all areas. Our array cost $2,000 but don't use that as a guide. Yours might be 0 times that, or half that, depending on your area and needs.
Q: How do solar panels affect the property's energy resilience?
Solar panels can significantly enhance a property's energy resilience by providing a reliable and sustainable source of electricity. They reduce dependence on the grid, allowing homeowners to generate their own power and potentially store excess energy in batteries. In the event of a power outage or grid failure, solar panels can continue to supply electricity, ensuring uninterrupted energy supply and boosting the property's overall energy resilience.
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: Can solar panels be installed on a community center or recreational facility?
Yes, solar panels can be installed on a community center or recreational facility. In fact, these types of buildings are often ideal for solar panel installations due to their large roof spaces and high energy consumption. Installing solar panels can help these facilities save on electricity costs and promote sustainable practices within the community.
Q: Can solar panels be used for camping or outdoor activities?
Yes, solar panels can be used for camping or outdoor activities. Portable solar panels are designed specifically for such purposes and provide a convenient and eco-friendly way to generate electricity in remote locations. They can charge batteries or power devices directly, allowing campers to have access to electricity even when they are away from traditional power sources.
Q: Are solar panels noisy?
No, solar panels are not noisy as they do not have any moving parts.
