Why choose our solar panel is you ideal choose?

1. The important raw material, Solar cells, come from domestic public company and Taiwan famous company. Quality assurance: 25 years long life span, Industry leading power output warranty 10 years 100%, 20 years 95%, 25 years 85%. 

There are some company which select inferior solar cells that are processed from recycled silicon material from small workshop, so their solar panel service life maybe less than 5 years because inferior solar cell power reduce much more every year.

2. Our company has automated production line for solar panel. Good technology, good quality assurance. Strong production ability: 300 pieces 300w solar panels can be manufactured per day. Most of company weld solar cell with artificial manual work. Bad manufacturing technique is difficult to keep consistency of products.


Q: Can the solar panels available be coated with a material (to improve it's looks) and not alter it's efficiency?
No. The only coatings I am aware of are those that reduce reflection so more light gets through the protective surface to the actual cells. Anything thing that affects appearance is going to be reflecting light back to the viewer and the photons of that light are not available for electricity or heat. If the appearance of the panels offends you, then they need to be concealed by a fence of panels around them that do not throw shadows on the panels.
Q: Please tell me what they are made of and how the materials help the solar cell produce electricity. Im doing a science projects so i need help on knowing all this info. Its a debate, so i need correct information please.I will please need more information about the bad things about solar energy and solar panels. Please say what solar panels do to create pollution or do anything that is not friendly to the environment. If you want just give me a website. Thank you
image voltaic cells paintings for the period of the photoelectric effect. Incoming photons knock out electrons of the textile, which being a semiconductor helps a small ability distinction. close to to the sunlight, each and everything could be very severe (like a Van Halen gig), radiation, energetic ions, magnetic fields, the works. of direction, NASA project planners could take all those issues into consideration. i ask your self what textile maintains to be stable at 5800? ok (or perhaps it fairly is not needed), and captures all photons of all energies, to be one hundred% powerful. The link provided by making use of Snow Blossom is extremely thrilling. I do in simple terms no longer look waiting to study the secondary link Thermophotovoltaics. Edit: image voltaic Flares may well be a difficulty. they're by making use of and great unpredictable, upward push for hundreds of miles, achieving hundreds of thousands of Kelvin.
Q: How does Solar Panel make Electricity ?
when sunlight hits a solar panel the photons from the light hit a layer in panel that converts it into electrons through conduction, thus making electricity
Q: Can I add more solar panel let say up to 200 watt and adding two 2 volts battery using the same charges controller and power inverter?
You can wire solar panels in parallel (i.e. positive to positive, negative to negative). Preferably, the panels should be similar to allow the output voltages to track. Otherwise, it may be necessary to include diodes in series with each panel so voltage variations do not have an adverse effect. The other alternative is to have the panels charging individual batteries and then combining the batteries through diodes before using the inverter. This approach would require separate charge controllers for each battery. Not quite as energy efficient as each diode causes a voltage drop (and so a power loss).
Q: What i would like to know is if you were using commercially available solar panels, clustered as close together as possible and spread out on one acre, how much electrical energy is produced? if u can 'translate' this into terms of ( hour of average daylight = powering a ____ for X units of time)
Fossil fuels will be depleted in a few hundred years. The sun will continue to produce power for the next 0 billion years. Solar cells are expensive to make and only 0% efficient. Some less efficient cells can be economically mass produced and set out over a very large area. This is how Germany made solar power a viable alternative to fossil fuels. America has an abundance of coal however and has been very slow in adopting solar power.
Q: i know that a solar panel of square meter generate 000 watts on a clear and sunny day, but i need to know the time rate. is it 000 watts per day or per hour? Thanks.

Q: Can solar panels be used to power a restaurant?
Yes, solar panels can be used to power a restaurant. Solar panels harness energy from the sun and convert it into electricity, which can be used to power various appliances and systems in a restaurant, including lighting, refrigeration, cooking equipment, and HVAC systems. By installing solar panels, restaurants can reduce their dependency on traditional energy sources, lower their electricity bills, and contribute to a cleaner and more sustainable environment.
Q: I own a townhome in the Phoenix area (my power company's SRP, if that makes a difference). Phoenix is a great place for solar. I could probably save money, in the long term, if I got some solar panels.But I am currently extremely broke, so I can't buy solar panels unless I will more or less immediately be paying no more than I am now per month, with little or nothing down. And most of the solar leasing places won't work with me, because (as is common for townhomes) I don't technically own my roof. I have permission to put things on it, but the property management people (or whoever actually owns my roof) won't sign the lease or whatever.Anyone know of either a way to buy solar panels without paying significantly more per month than I already do for electricity, or a solar leasing company that can work with the restrictions I have?
There are companies who would install solar panels on your roof for no cost. The catch is that they get the power generated for the first 20 years which is the useful life of the panels then you get what's left of the obsolete panels, meanwhile you're required to purchase your power from them at allegedly reduced rates but there is no guarantee that they would remain reduced versus the market once they have you locked in. It's like how the cell phone companies will give you a free cell phone if you sign a contract. Keep in mind that once you've factored in the installation costs and the useful life of the panels, the effective costs of solar photovoltaic energy is about 23 cents to 43 cents a kwh while grid power is about 5 cents per kwh to the consumer, 3 cents per kwh to the utilities for coal generation. It's just that so few people understand how to project an initial capital expense with periodic future returns through discounted cash flow, hence people think solar power is free out of ignorance. Without government incentives, there are no economic benefits to solar and most solar installers structure the sales such that they gain the economic benefit instead of the consumer who is often ignorant of how to calculate the financials.
Q: What is the most efficient solar panel, how many would we need to power the United States, and how much land would it take?
50 billion panels million acres nukes are better. MIKE
Q: I would like to know how much a solar panel would cost for a wingspan of 208 ft for a plane
