1.Product Description
We Offer the mono solar panels 250W, 255W, 260W 300W, poly solar panels 250W 260W 300W. You can find different mono solar panels and poly solar panels . We are the professional solar panels solar modules supplier.
Solar panels or modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of solar panels or modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon.
Solar panels constitute the solar array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. Each solar panel or module is rated by its DC output power under standard test conditions, and typically ranges from 100w to 320 watts. Ground mounted photovoltaic system are usually large, utility-scale solar power plants. Their solar panels or modules are held in place by racks or frames that are attached to ground based mounting supports.

- Q: Hey guys :)Well I'm in the middle of doing my PSHCE coursework on sustainable energy, focusing on solar panels. I just wanted to ask you what your opinions are of them? Are they really worth it? Are they sustainable? Will they reduce our energy bills? Those sort of questions :)If you are interested in installing solar panels, please mention that, as it would be great! There's lots of information about them on this site ----
- I have a boat in a sunny place and four 80 watt panels. These will run my fridge Tv and a few LED's. I still have to run my engine for hot water and washing machine. My Batteries only last a few years and are a real pain. I go on the mains when I can to get the batteries topped up. The panels are ok if there is nothing else, they are not the answer to the future of energy supply. There is also the moral aspect of the feed in tariff. For the rich to load their electricity bill onto the less well off is not acceptable and those panels on the roof tell all your neighbors that you are doing it. That will show a greedy selfish attitude. If they are any good why don't the power companies buy them and save buying coal?
- 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
- The panels themselves efficiency are 5 to 8 percent at converting sun energy to electicity currently.But as what you said above,the conversion efficienc is about 70%，so a KW solar panel can produce 3.5KW in 5 hours,The solar panels of China are compared comparably to other contries.The highest efficiency of 24% is rare,they are not widely avaliable.
- Q: Mono-crystalline or poly-crystalline solar panel?
- All solar photovoltaics drop in efficiencies with higher temperatures but it isn't the 45+ C you have to worry about but rather the heat from the sunlight striking the panels. There are hybrid systems which passes water in pipes attached to the back of the solar panels to cool the panels and preheat the water for solar thermal collectors. The difference between mono-crystalline and poly-crystalline are that mono-crystalline are more efficient and more costly to make.
- Q: I have:4- 5v 200ma solar panels5- 3v ,000ma solar panels- 7amp charge controller- 400watt inverterNow I have all my solar panels linked in series which in theory should give me 35v, 5.8 amps at 203 watts. Is this correct?The main question is, what kind of battery should I get so I can run my miscellaneous electronics off of it?I may not have explained it so well so if you need more information, feel free to ask.
- I okorder and they have deep cycle batteries exclusively made for solar panels. but in theory you should get more than one because it only takes around 4-5 volts to charge the battery and you do not want to have it that high even with a charge controller which i would also recommend getting which is like $50 on OKorder but a charge controller is used so you do not overcharge the batteries and fry them or undercharge the batteries and weaken its life it gets it just perfect. it lets the current go in and when it is charged fully nothing goes in an nothing comes out.... for a inverter the one i was going to get was $70 500 watt inverter but changes it from dc to ac...hope i helped
- Q: I was trying to look online for solar panels for my home to take some of the strain off of using oil and electricity but I find it very hard to understand exactly how they are used.Like one that I looked up is 00 watts.....is that like a light bulb watt? How many things can that power? Is it really cheaper in the long run because the panels are very expensive?If anyone has web sites that can explain this to me I would appreciate a link, or anyone to answer part of my question.

- Q: I am looking to run 2 basic shoplights, each with 2- 32 watt T8 flourecent tubes for 6 hours a day for an indoor garden. Location WI.
- Excellent answer from Server Room above. I notice that you mention 45-watt panels, suggesting that maybe you are considering the kind of kit that comes with 3 5-watt panels. I'd recommend against that, as the type of panel that comes in those kits tends to be optimistically rated, and not durable, either. The best way to go for this sort of thing is to use grid power. Then if you want to offset your usage with grid-tied solar, that can be an independent consideration.
- Q: Hey was looking at a 5 watt 2 volt solar panel and was wondering if it'd be enough to power a regular light bulb. Also need to power a 5volt 6.5 amp pump for at most a minute at a time. So basically if I had this panel would I be able to plug a lamp into it and have it light for 5+ hours at a time with the possibility of running the pump? If not what size panel would I need?
- NO ! Pump needs 747 watts power. And you need to buy one more expensive DC to AC converter to make it work. Use solar panel at least has 000W output.
- Q: Can solar panels be used to power a museum?
- Yes, solar panels can certainly be used to power a museum. Solar panels are a reliable and sustainable source of energy that can generate electricity to meet the power requirements of a museum. By harnessing solar energy, museums can reduce their carbon footprint, lower energy costs, and promote environmental sustainability.
- Q: Can solar panels work during cloudy or rainy days?
- Yes, solar panels can still work during cloudy or rainy days, but their efficiency is significantly reduced. Solar panels generate electricity by converting sunlight into usable energy, so the amount of energy produced is directly related to the amount of sunlight available. Cloudy or rainy weather reduces the intensity of sunlight reaching the panels, resulting in a lower electricity output. However, solar panels can still generate some power even in these conditions, making them a viable source of renewable energy even on less sunny days.
- Q: Can solar panels be installed on a school or university campus?
- Yes, solar panels can be installed on a school or university campus. Many educational institutions are adopting solar energy as a sustainable and cost-effective solution for their energy needs. Installing solar panels not only reduces greenhouse gas emissions but also provides educational opportunities for students to learn about renewable energy. Additionally, it can save the institution money on electricity bills and potentially generate revenue through excess energy production.
