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: I am seriously thinking about installing PhotoVoltais Solar panels (that generate electricity) on my roof. Besides the usual (cost, ROI, etc.), I was researching for the maintenance of these panels. We have tall trees around the house and needles and leaves fall on our roof all the time... not to mention the dirt and grime that collects over time.Do these decrease the capacity of the panels? Do the panels require a regular maintenance?Thanks!
- New solar panels are clean and shiny and they look cool. Then they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Solar panels must be regularly cleaned and maintained in order to keep them operating efficiently and maximize the amount of sunlight they convert into electricity. Unlike windows your solar system needs to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be. Solar panels will attract dirt, dust, soot, pollen, tree sap and salt crystals in coastal regions creating a fine layer of grime. This layer reduces the amount of light reaching the silicon cells under the glass surface and reduces the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be. Some have reported a ten to fifteen percent loss of solar output due to dirty panels. From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerable reduce its effectiveness. See much more about solar panels maintenance below link
- Q: my solar panel is 5v 50 mA, and im making iphone USB charger so i need to connect + with 00 ohm resister and to data - and + so what resister will be okay..?
- Just connect the 5 volts out of the panel directly to the iphone via an USB connector. BUT, is the panel output always 5 volts, ±0.25 volts? Because that is the USB specification, and anything outside of those values could damage your iphone. And solar panels are known for their wide swings in voltage. Bottom line, resistor not needed, and you need to be positive you supply the correct voltage to the iphone. Best way to do that is to start with a solar panel that puts out at least 7 volts and use a LM7805 regulator. The only resistors needed are those to tie the data lines into a certain combination of resistance and voltage so that the iphone is fooled into thinking that a proper USB is connected. That would NOT involve a 00 ohm resistor. Search online for the proper values and connections. edit: are you repeating your same inane question with a different account? That is totally against the rules and could get you suspended.
- Q: how the power output of solar panels fitted to a house can chargenothing on the internet really answers this question, any information will really help..this is for GCSE, i don't really understand the meaning of the question. does it ask how the solar panel egts charged, and how it works? i don't get how you can charge a solar panel and is heat the only way you can produce electricity for it??please answer if you know! much appreciated!!! thank you so so so so so so so much, in advance =)
- Solar panels do NOT get charged, so the question is junk, or you misstated it. Solar panels are used to charge a battery bank, which stores energy for times when there is no sun. Then energy from the batteries is used, via an inverter, to power appliances in the house. OR do you mean how the power output of solar panels can CHANGE? In that case, they change when the sun moves, such as behind a cloud, or just changes angle in the sky, or goes out.
- Q: Can solar panels be installed on a car?
- Yes, solar panels can be installed on cars. These panels can convert sunlight into electricity, which can then be used to power various components of a car, such as the battery, air conditioning, or even the motor. Solar panels on cars are a growing trend as they offer a sustainable and renewable energy source, reducing dependency on fossil fuels and lowering carbon emissions. However, the effectiveness of solar panels on cars may vary depending on factors such as the size of the panels, the amount of sunlight available, and the energy demands of the vehicle.
- Q: Hoping to find instruction, materials list and hardware needed to construct solar panels myself, how many and make it happen instead of talking about it
- Silica based solar cells are not the kind of thing you whomp up in you basement. Here are a couple ideas for solar systems you can build and install yourself. Take a 4 x 8 sheet of /2 inch plywood. Frame sides with 2 x 4's. Screw tin cans in a staggered row (checker board) pattern inside frame. The more cans the more heat you get so place them nearly touching. Paint cans and entire assembly flat black. Cover top with glass, plexiglass (best) or heavy mill clear plastic (cheapest)Place on roof. Drill 3-4 inch holes in opposing sides. Run pipe or tubing into house. Attach to small low speed fan. The black paint will absorb sunlight and heat. The air moving through box will carry heat into house. It's a cheap efficient way to help heat your home. You can vary size and shape of box to fit your roof. If you use more than one box, hook them up in series. More boxes mean more surface area means more heat. To heat water. Take a steel tank. A car gas tank works well. It is galvanized so it won't rust, is cheap, and easily available at any auto salvage yard. But you will have to flush in throughly to remove gasoline odor. A steel 55 gallon drum is easier to work with but may cost more. Paint exterior of tank flat black. Weld/glue/clamp water pipes to tank. Place on ground in area that gets lots of sunlight. Attach water supply to tank and route discharge pipe to house or appliance. Black painted steel absorbs heat from sun light and heats water. In spring and fall you get warm to hot water. In summer you get scalding hot water and in winter you get cold to luke warm water. Both of these solar powered systems are seasonal and their output varies according to location and climate, but they are very inexpensive and easy to build and provide FREE heat and/or hot water for many years with little or no maintainence.
- Q: I'm trying to charge rechargeable AA batteries with a solar panel. What gauge wire should I use to connect the panel to the batteries? I know I'm not going to have a lot of current going through so the wire size doesn't really matter. Can the wire be too thick thoShould I ugh? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size diode? My panel is 4.8V 50mA. Can I just hook the panel straight into the batteries or do I need something else?
- In order: .? Just about any wire will do.? You can handle 50 mA over just about anything, even 28 gauge telephone wire.? Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.? You need a diode.? If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.? The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.? You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.? This gives you maximum current output from your panel.
- Q: I am in need of solar panels and the batteries that I can store the energy in. I need to be able to run a laptop, cell phone, and LED lights from it. When I research I see all sorts of options with regards to watts, VMPs, and AMPs. I also see that I may need a controller, an inverter, and various other components. Can anyone help me through these terms and what i need to know in order to efficiently generate and store the electricity. Thanks
- I think the point you're trying to make is that solar electricity is more expensive than other means of mass produced electricity today, and I would agree. However, that doesn't mean that solar panels are not worthwhile, especially to a consumer in the right location. After the electric company adds in its distribution fees and profit, residential solar electric can actually be cheaper. And in fact, we have had panels on our roof for the past 5 years. Somewhere in the world, there's a factory producing AA batteries to use in flashlights, cameras, and so forth. I'm certain the factory does not run off AA batteries, yet I find AA batteries invaluable for certain things around the house.
- Q: Heard you can put solar panels on laptops Anyone know if it can work on a Dell mini 0v? I've seen he USB slot solar pana but can someone tell me where to gt these?
- If okorder /
- 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?
- It varies from state to state.
- Q: How much roof space is needed for solar panels?
- The amount of roof space needed for solar panels varies depending on various factors such as the size and efficiency of the panels, the energy requirements of the building, and the geographical location. However, on average, a typical residential solar panel system requires approximately 100 to 400 square feet of roof space.
