Q: Can solar panels store excess energy?
No, solar panels cannot store excess energy. However, additional equipment such as batteries or energy storage systems can be installed alongside solar panels to store any surplus energy generated for later use.
Q: Ok so if i wanted to put a solar panel on my house and i live where it snows, will that be a problem? If the snow covers the solar panel will that be a problem? If so then do i have to climb on my roof and clear it off or what?
It shouldnt be a problem being where it snows, as long as you dont mind clearing it off a lot to recieve maximum efficiency! Or else it should work anyways but not as well covered with snow.
Q: Can solar panels be used in areas with high pollution levels?
Yes, solar panels can be used in areas with high pollution levels. While pollution levels may slightly reduce the efficiency of solar panels due to decreased sunlight reaching the panels, they can still generate electricity. Additionally, solar panels can help mitigate pollution by providing clean and renewable energy, reducing reliance on fossil fuels and contributing to a cleaner environment.
Q: What are the maintenance requirements for solar panels?
The maintenance requirements for solar panels typically involve regular cleaning to remove dirt and debris, as well as ensuring that they are not shaded by nearby trees or structures. Additionally, occasional inspections for any signs of damage or malfunction are recommended, and if necessary, repairs or replacements may need to be carried out by a professional. Overall, solar panels are known for their low maintenance needs, making them a cost-effective and sustainable energy solution.
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: There are places in the US where it is sunny almost all the time, like the southwest. But if we covered an area of the Sahara with solar panels, the sun exposure with the area would generate enough energy for the whole US at least. Plus, I would imagine it would be a great source of income for those countries.Why isn't this a topic under discussion or even mentioned between countries' governments/in Congress/in politicians' viewpoints?
Good question. One of the reasons is the greed of manufacturing companies. No matter the profit margin of the product, they seem to want to charge so high a price that the break even point is ten years down the road, so the true savings are few. The cost of solar panels should have dropped way lower than they have by now. I believe that the political correctness of the product will tempt the manufacturers to keep the prices artificially high. One other answerer is right, the panels are very fragile, and damage would destroy the investment, so new inroads need to occur in technology to protect the panels from damage. Somewhere in the middle is a profit for the manufacturers, and savings for the consumer. I hope we find that middle-ground soon.
Q: Can solar panels be used for charging batteries?
Yes, solar panels can be used for charging batteries. Solar panels convert sunlight into electricity, which can be used to charge batteries and store energy for later use. This process is commonly used in off-grid systems or to power portable devices and vehicles.
Q: Can solar panels be installed on a streetlight?
Yes, solar panels can be installed on a streetlight. This is known as solar street lighting, where solar panels are mounted on top of streetlights to generate electricity from sunlight and power the lights.
Q: can solar panels be on houses? malls?stores? WHAT ABOUT TRAINS?
Solar panels are, well panels that take solar energy from the sun, and use it as heat or electricity. It is used for many things but depending on the power of the sun and the panel, they can be used for trains,houses to heat them but you need a lot of sun, and they don't work without sun obviously.
Q: I am starting to think about solar panels as an option for my home. I have done some research on panels, to be honest its all very confusing. There are many different panels some with 60 watts some all the way up to 20 watts. My household currently uses about 2700 to 3400 kWh every two months. So based off of my power usage maybe you can answer some of the following questions:What kind of panels should I be looking at?Which panel manufacturers give the best bang for the buck (reliable/affordable)?Anything else I should be concerned about?I am just starting out in educating myself on solar power so please excuse me if I sound very naive. Any information that you may have will be helpful. Thanks in advance.
solar cell is a solar cell solar panel are many solar cells.... Typically people refer to a single solar panel as a solar panel, even though they should be reffering to it as a solar cell. A solar panel is a panel of solar cells working in conjunction with each other. I hope that makes sense it is just the incorrect terminology people always use.
