- Q:Can solar panels be installed on a residential community?
- Yes, solar panels can be installed on a residential community. Many residential communities have implemented solar panel systems to generate clean and renewable energy for homes. These installations can help reduce electricity costs, decrease reliance on fossil fuels, and contribute to a more sustainable living environment.
- Q:Can solar panels be used to power electric vehicles?
- Yes, solar panels can be used to power electric vehicles. Solar panels can convert sunlight into electricity, which can then be stored in a battery and used to power an electric vehicle. This helps reduce dependence on fossil fuels and promotes sustainable transportation.
- Q:hi everyone..i wanna do my major project on solar panels...so anyone kindly tell me the projects based on solar panels..
- I have done this in my project too and a solar panel, two wires, a circuit/project board, an LED light/a small fan,a switch and a solderer. Just solder the wires to the positive and negative parts of the panel, put the wires connected to the panel to the board put the LED's on the other side and the switch together with it shine light on the panel and the light/fan will work.(If it dosen't work, please DO NOT consult ME.)
- Q:Aren't batteries bad for the environment?Toxic?Expensive? With small solar panels phones, iPod's, laptops other small electronics could be smaller, slimmer, more efficient cost people less to charge every day. Maybe a small battery inside as a backup and to store the Solar energy for night time. But overall, batteries should be optional. So big question:Why aren't electronics being produced with solar panels?
- Cost and and it would be inconvenient to the consumer in this Gotta have instant gratification society. take the amount of money you paid for your MP3 player- double it- would you still have bought it at that price? That IS what happens when you add in a 2 to 0 dollar component. Besides- the energy required for most items you cite- a solar panel makes it not portable. While you might be able to arbittrarily decide to go without an MP3 player for 24 hours, could you do it for a week? How about your cell phone? It uses more power- so go without it for 2 weeks. You still need batteries to be charged by solar panels due to one major flaw of solar panels- they do not work in the dark. So in effect all you are really doing is weighing the device down with a solar panel, and you still have not gotten away from a need for a battery. I don't know about you, but I have an MP3 player about the diameter of a 50 cent piece- where are you going to put the solar panel??? It will not have enough power to operate the device, and marginal at best for charginthe battery which would take hours instead of the minutes it takes connected to a USB port.
- Q:Is there any way to charge my laptop with a solar panel? Is there any panel like that. Or if I work on panels can I do something like that. If you know anything about it, can you just help me? Thanks a lot.
- A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
- Q:do solar panels create electricity from the ultraviolet light created from the sun? because they only have an efficientcy of like 8% and this scientist found out a way to collect the visible light also, and he says the solar panel could have an effeciency of up to 80%! so my question really is, do solar penels creat electricity from heat? do you know of anything that can?
- Solar panels create a current from light. A photon strikes a crystal lattice and anelectron is freed and flows as a current
- Q:Can solar panels be used for irrigation systems?
- Yes, solar panels can be used for irrigation systems. Solar energy can power the pumps and other electrical components required for irrigation, reducing the reliance on fossil fuels and making the system more sustainable and cost-effective.
- Q:My project needs to build a thermal solar panel that would be used as a demonstrational rig. The dimensions i am allowed do not allow me to use a normal thermal solar panel so i have decided to use the heat exchanger from the back of a fridge. Although this is possible to use what equation would i use to prove the power of the sun would actually heat up the water. More importantly when the rig is demonstrated to students, they will need to be able to determine if the raise in temperature given by the thermometers is what should be given. Variables of the rig will include: Angle of the panel, Light intensity, Direction of panel, and more importantly the flow rate of the water travelling through the pipes. What equation includes those variables (change in temperature, flow rate) and would allow me to incorporate the angle of the panel. The light source would be a lamp so i would also need to know how much of the energy from the lamp is actually being used by the panel?
- Forget the long winded discussion above. There are so many variables that you cannot calculate the outcome. This does not mean that the experiment is a failure. It gives you information on the fact that water can be heated in this manner, and that you can vary the result by modifying the variables.
- Q:Can solar panels be used in commercial buildings or industrial settings?
- Yes, solar panels can definitely be used in commercial buildings or industrial settings. In fact, they are increasingly being installed in such settings because of their numerous benefits. Solar panels not only help businesses reduce their carbon footprint and contribute to sustainability goals, but they also provide long-term cost savings by generating renewable energy and reducing electricity bills. Many commercial and industrial buildings have large rooftops or open spaces that are ideal for solar panel installations, allowing them to harness the sun's energy efficiently. Additionally, businesses can take advantage of various incentives and government programs that promote the adoption of solar energy, making it a viable and attractive option for commercial and industrial sectors.
- Q:I was told by a veteran that jcpl had a program that installs free solar systems for disabled vets.If this is true who do i contact?
- yes. there is a free solar panel program for veterans.
