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: I read on CNN's website last year some company was creating a very cheap type of solar panel, that needs minimal maintenance and and has minimal glare from the sun. And the creator of the project said he one day wanted to cover every rooftop in the US with these solar panels. Seems like a good idea to me but I havent heared anything of it for a long time and I don't know what they are called... any help?: The cheapest will be solar paint where you lay down some wires and paint the panel on. Solar roof tiles are also coming along but each tile has to be wired in. Currently the target is $ a watt. The efficiencies of these panels are very low but if the cost is low enough then the efficiencies won't matter. Keep in mind that even fossil fuel is solar power, just solar power captured by photosynthesis millions of years ago, and photosynthesis has a maximum theoretical efficiency of 6.6% with most plants achieving less than % efficiency so even an inefficient solar paint already outstrips our current energy sources in terms of efficiencies. The real problem is the business model. With solar energy you can sell the panels upfront but then what do you do for an income whereas with fossil fuels, you sell every kwh and bill each month.

Q: Can solar panels be used in areas with high levels of rainfall?: Yes, solar panels can be used in areas with high levels of rainfall. Rainfall does not necessarily affect the functioning of solar panels as they primarily rely on sunlight to generate electricity. However, it is important to ensure that the solar panels are properly installed and maintained to prevent any water damage or reduced efficiency caused by excessive rain.

Q: Is there a free site or resource that will teach you how to do this? Hopefully step by step and tells you how to buy all the parts ect?Which is the best resource for sale earth4energy, homemadeenergy, ect? Do they actually work and also as well as those which are professionally done?They say it will cost under $200 for a panel, but how much will this panel actually produce I mean how many panels would you have to make to produce 00% of your homes energy?: I have no idea the out put of the panel you plan to make, but $200.00 will not even come close to power much. You don't say whether you want to power your house straight from the solar panels (not possible, because the sun doesn't shine 24/7). That being said,you will need a very large array to power your house,going to battery's to inverter to get AC power. Your initial cost would be around $25000,00, but you might be eligible for a tax rebate and maybe a rebate from your state and power company. There is a lot more to be said on the subject,but this is enough to either get you started or discouraged.

Q: I'm curious, for those who have had solar panels installed on the rooves of their houses:How much did you pay? How much energy do the panels produce? Did it dramatically cut down on your electricity bill? Was it worth it? Thanks!: I'm okorder /

Q: Can solar panels be used for powering an airport or transportation hub?: Yes, solar panels can be used to power an airport or transportation hub. Solar energy can be harnessed through photovoltaic cells in solar panels, which convert sunlight into electricity. By installing a sufficient number of solar panels on rooftops, parking lots, or open spaces in these facilities, it is possible to generate enough clean and renewable energy to meet a significant portion of their power needs. This not only helps reduce carbon emissions and dependence on fossil fuels but also lowers operating costs in the long run. Many airports and transportation hubs worldwide have already adopted solar power as a sustainable energy solution.

Q: i was told that by making a solar panel they cause more pollution than they will end up getting rid of. Is that true?: The amount of energy needed to extract the raw materials from the Earth exceeds the amount the finished PV panels produce.Processing the materals takes additional energy.After manufacturing they have to be transported.Photovoltaic panels only generate </2 volt per square inch in bright sunlight.They become less efficient when they get dirty.

Q: how to make electricty using solar panels or wind generator: www.okorder / or you can just google solar panel(s)

Q: i am very new to the solar world and i need help with some stuff to understand what i need to do.what AH battery should i use? i am planning on getting a 2V deep cycle gel based battery but i want to get the most power for my system so should i use something like a few 00AH in a battery bank system or a bunch or 50 or so amp hour batteries in a bank. also what kind of power am i looking at for the best battery system. in other words what kind of basic appliances like lighting, laptop,space heaters etc can can i run on the selected battery system and for how long? any help would be highly appreciated.: A lot will depend on the Sun light available at location where you plan to install this. The electricity the panel generates is at times 0-20% only of what it is rated. Start small and do some initial readings on the generation and then scale up.

Q: i've heard that solar panel batteries have to be replaced withen 5-0 years. how much do solar panel batteries cost? please include sources!: Solar panels produce but do not store electricity. Most decent solar panels should last for a few decades. They may be used to augment grid power with out batteries. Batteries that are used for storage in a battery backup system are the same ones that are used if the power were hydro, gen-set or grid. There are a variety of battery types with different shelf lives. Some are warrantied for 0 years that may last 20, but they cost more. Exactly how long they do last will depend on the environment they are kept. The capacity and number of batteries will effect the cost. The link below will give you a very good overview of pros and cons of the various types, along with links to some manufacturers.

Q: Can solar panels be installed on waste treatment plants?: Yes, solar panels can be installed on waste treatment plants. In fact, waste treatment plants provide ample space and suitable infrastructure for the installation of solar panels. This can help offset the electricity consumption of the plant and reduce its carbon footprint, making it a sustainable and environmentally friendly option. Additionally, solar panels can contribute to cost savings by generating clean energy on-site.
