Q:For example, how many large solar panels would you need to operate a greenhouse with lighting for simulate sun during cloudy weather, a scheduled sprinkle system and other such things?I'm looking for a very in depth answer.
if you are talking electrical solar panels, they are rated in watts they generate in full sun. usually these panels are used in tandem with batteries, so they charge up during the day and the batteries hold a reserve of power for later use. If you figure 8 hours of useful sunlight per day, then a 40 watt panel will light a 40 watt bulb for 8 hours. you can also measure capacity in watt-hours. this would be 40x8 = 320 watt-hours. the general method is to determine how much electricity demand you have over a 24 hour period to get the total watt-hours. then divide that by the watt-hour capacity of one panel to get the number of panels needed.
Q:Can solar panels be used in areas with high temperatures?
Yes, solar panels can be used in areas with high temperatures. In fact, solar panels are designed to withstand a wide range of temperatures, including high heat. While excessive heat may slightly reduce their efficiency, modern solar panels are equipped with cooling mechanisms that help maintain their performance even in hot climates.
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?
Yes your right, solar panels (photovoltics) could be used to make electricity for small electronics. Right now solar cells are on many calculators, and even flashlight. But the problem is the lenght of time the cells take to charge the device, verses the power demand. I don;t think the size of the panels, and the amount of time needed to charge the device are practical. One think I have been thinking is that every one should have a photovoltaic panel to charge a battery. Then, use the battery to charge cell phones, MP3 palyers. The panel and the battery could be about the 8 x inches, and could sit in window, or on a dash board to get charged, then used in doors over night to charge devices.
Q:if car companies install solar panels on cars, like in all the car were the sun can reach that would reduce the consumption of gas in the summer, and might save some energy for winter and if that energy is not enough they can use gas or electricity i think that would be a lot of savings, and less contamination i don't know that is my idea what do you people think?
There okorder Part of the problem of putting solar panels on a vehicle is that at almost no time is the orientation for the panels correct. You would not consider putting solar panels on the shady side of your house, or not tilted and aimed properly. This is because solar panels are expensive and you would like to make sure that they are as efficient as possible. A better plan may be to put solar panels on your house and buy an electric car. Have the panels feed power into the grid during the day where you can be paid at the higher daytime rates and then charge your vehicle at the lower night time rates from the grid.
Q:If I wanted to put some solar panels on my roof, how many would i need and how many watts would they have to be to be able to power my whole house?
all depend to the surface of your solar panel
Q:could any tell me what type off panel is the best tube or flat and how much it should be. I live in N Ireland
I assume you're talking about heating water. Based on what I've seen, the spiral tubes seem to heat the water to a higher temperature than the flat panels, probably because the water has to follow a longer path and has more time to heat. This type of panel will heat the water to a high enough temperature for almost any household application, but you need to be careful about how you set it up. I once saw a pool that had been equipped with that type of heating system, and it produced enough heat to melt one of the PVC pipes. It was a vertical pipe next to the filter, and it had fallen over onto the ground, pinching off the flow of water. This was in Arizona, so it may not get that hot in your area.
Q:I remember hearing somewhere that solar panels may attract light rays away from plants thus having a potentially negative effect on the plants. I can't remember where I heard it but I'm curious if there is any truth to it.
solar panels don't literary attract light but when the light hits it it turns into stored energy planets dont give of heat or ray if u mean stars like the sun yes. it doesn't have anything to do with planets its star noble gases that stuff u can steal light it just gets it other than wasting it solar panels are better than those factory thingys
Q:Here's a little idea I though might help everyone out in Iraq a little: How about if the US mass produces solar panels that are small enough to carry (maybe one foot by three feet) that have a regular power outlet on them to the Iraqis? We could send convoys to the people waiting in line to buy gas and give each person one free solar panel. Why?. A lot of people are buying gas to run generators for air conditioning, not to fuel vehicles. 2. It would help reduce the gas lines if people only needed gas for cars instead of their generators too.3. It would help reduce the fighting over the power grid if people didn't need the grid for their own electrical power.My theory is, once every family in Iraq has enough of these panels that they don't even care about the power grid (during the daytime anyway) it would be much easier to fix the power grid. Maybe these solar panels could even connect to and add to the power grid.
A big problem with your theory is that because the solar panel is so small the amount of energy gathered from it would be small and probably wouldnt be able to provide electricity for things and even if it did it wouldn't last very long. its a good idea but it just won't work. in order to produce the amount of energy your talking about the solar panels would have to be the size of a roof and be placed on the rooftop or a hill or something. people wuldnt be able to carry that around.
Q:So I'm trying to figure out what to ask for my birthday because its one of the few times I can get stuff for no reason, like stuff I don't normally go to the store to buy. (i dont go to the store to get much at all anyway).Anyway, I'm interested in solar panels and led and electronics and i was wondering if there is anything not over expensive that would be cool. Some things I'm interested in:solar, wind, water energyGadgets (multitools, swiss army knives)Vibram fivefingersdrawingmaking stuff (duct tape wallets, stuff out of altoids containers)basically technology and outdoors-gear stuffoh and im 6 turnin 7 male.
solar panel is expensive, but small solar panel is not expensive, for example, 5w solar panel, solar light also not expensive led light also not expensive. i am not sure about other stuff that you said
Q:We have LED at the output of 40 watts and is used for 0 hours giving us 400 Watts-hr of energy consumed.Rechargable batteries needed are 2 V. 400/2 gives us 34 Ampere-hour battery needed. If we want it for 3 days, It would be 34x3=00 Ah. So the battery needed 00 AhNow how do I select the solar panel which can charge this/these batteries? What should be its rating?
Be aware that you cannot discharge the full capacity of a lead-acid battery without destroying the battery. With a normal battery of this type, you would only want to discharge about 20%, so you would need a 70 AH battery bank. For the 3-day requirement, 500 AH. This is still within reason. If you didn't have the 3-day requirement, you might consider going with NiMH batteries. Back to the 500 AH bank, you would usually charge at at least 5% C, or 25 amps. At the 5 volts that you need for charging, this is 375 watts. Possibly you could go as low as 200 watts.
