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: Hi All,I need some resources for a research project i'm doing on Solar Panels/Cells.So do you know of any good books or online materials that basically covers how solar cellwork from level 0 to calculating the energy output based on intensity of the light and the area of the panel. Book titles will be preferable but i'd like to build a strong base before tackling long and complicated formula(s)... so any suggestions? Your help will be appreciated :)THANKS IN ADVANCE!!: My guess is that you must pick up everything that have to do with solar power at www.okorder .

Q: Hi.How efficienent are solar panels? I mean, suppose we install a kw panel.. Wil it produce 5kw in 5 hours of good sun light?Or like if its 80 percent efficient, wil it produce 4kw and so on.Also, do the chinese solar panels give the same results as compared with panels from other countries?I live in india, so we get plenty of sunlight during the day.Thanks: Most okorder

Q: If a solar panel (using 36 3x6 solar cells) puts out 60 watts, how many panels would I need (for a house) if I use a max of 2300 kWh in a month? I checked my electric usage for the past 2 years and the kWh is usually lower but I wanted to use the most kWh used (2300) for my question. Thanks!: The latter one has some strategies to consider for cutting your power consumption even more by timing your freezers and refrigerators..

Q: Can solar panels be used in countries with limited sunlight?: Yes, solar panels can still be used in countries with limited sunlight. While solar panels are most effective in regions with abundant sunlight, they can still generate electricity in areas with less sunlight. Even countries with limited sunlight exposure can benefit from solar energy by utilizing advanced solar technologies and optimizing panel placement to maximize energy production. Additionally, solar panels can still generate electricity on cloudy or overcast days, although at a reduced efficiency compared to sunny days.

Q: can u use a light bulb instead of the sun to power a solar panel: Solar Powered Light Bulbs

Q: my solar car works when using the Battery but when there is sunlight i connect the wires to the solar panel and it does not work...................HELP: leave the car in the sun for a few hours to see if it charges. if not, the panel is defective. get it replaced b4 the science fair

Q: Can solar panels be used to power a shopping mall?: Yes, solar panels can be used to power a shopping mall. By installing a sufficient number of solar panels on the roof or surrounding areas of the mall, it is possible to generate enough electricity to meet a significant portion, if not all, of its power needs. This renewable energy source can reduce the mall's reliance on traditional electricity sources and contribute to a more sustainable and environmentally friendly operation.

Q: This is for my science project and i cannot figure it outWe assumed that blue light shining on a solar panel would give off the higher volt reading because it has the shortest wavelength and the highest energy, but it was actually the lowest. Why does this happen? Im very confused And cant find the answer anywhere.... ，thank you!!: I okorder /

Q: Are solar panels suitable for commercial use?: Yes, solar panels are suitable for commercial use. They are a cost-effective and sustainable energy solution for businesses, providing long-term energy savings and reducing carbon emissions. Additionally, advancements in technology have made solar panels more efficient and affordable, making them a viable option for commercial establishments of all sizes.

Q: Can solar panels be used to power a space station?: Yes, solar panels can be used to power a space station. In fact, many space stations, including the International Space Station (ISS), utilize solar panels as their primary source of electrical power. These panels convert sunlight into electricity, providing a sustainable and renewable energy source for the space station's various systems and experiments.
