Q:How Much energy does Solar Panel Produce,and How long can Solar Panels go without maintenance.
Solar panels come in many kinds, using a variety of technologies and sizes, but the most common is still the crystalline silicon type. The power produced is variable, but the better ones you can buy approach 20% efficiency, and the peak energy from the sun is 200W/m^2 (Watts per square meter). This only occurs when the panel is lined up with the sun on a clear day with the sun high in the sky. The efficiency is also affected by how the electrical energy is taken from the panel, and the temperature of the panel. In the full sun the temperature approaches 60C, so the voltage drops. The links below provide a lot of information about such matters. A BP panel 50mm x 674mm gives a peak power of 20W. This is .07 square meters. As you can see this is very close to 20%. (The third link). However this is less in practice because the sun may not be full sun and may not be perpendicular to the panel. The output drops as the cosine of the angle to the sun, more or less. Even with peak sun this would produce only about 00W charging a 2V battery directly, unless an electronic Maximum Power Point Tracking (MPPT) charge control is used.
Q:Can solar panels be installed on a house with a flat roof?
Yes, solar panels can be installed on a house with a flat roof.
Q:Please, I want a good definition. :DD
Solar panel is a battery of solar cells. Solar cell is a device which uses the sun's rays to produce electricity by the photovoltaic effect. The photovoltaic effect involves the creation of a voltage (or a corresponding electric current) in a material upon exposure to electromagnetic radiation. It utilizes the generation of a voltage when radiant energy falls on the boundary between dissimilar substances (as two different semiconductors).
Q:Interested to know if it is possible to install Solar Panels to run my Jacuzzi?Don't want to do the whole house just the jacuzzi anybody have any ideas Thanks
You can do this by isolating the jacuzzi, you will need a solar array adequate for the power draw of the jacuzzi, a charge controller, battery bank, off-grid inverter and switch gear. This is the expensive way to go--especially if you are planning to heat the water with the solar. A better option would be to heat the jacuzzi with solar thermal panels. It is plumbing instead of electrical, but the cost would be much less. If you still want to do PV (electric) solar, think about putting a non-isolated grid-tie solar array on your home. They are much cheaper, and if you think about it, it really does not matter if you use the solar electricity to run a light, a fridge, a TV, or a Jacuzzi, that amount of power is subtracted from your overall house power bill. Just size the array for the power output of the jacuzzi, and let the power meter do the rest. Your overall result will be the same and the system will be half the price, or less.
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:What makes them stop working after a while?
could be temperature, poor design and U-V damage If they are outdoor lamps like mine it is more likely the rechargeable batterys are bad.
Q:I'm making a model of a solar photovoltaic tower for a school project. I need a way to store energy, and we thought about using capacitors (mainly because of our somewhat limited funding). The tower will have a small photovoltaic panel (around the size of a laptop keyboard with number pad) and some (around 50) quot;heliostats(just the mirrors, no moving parts). What kind of capacitors should i use? and would a capacitor bank be better? i am getting confused with all those uF, pF and can't see the difference.Thanx in advance
If you have a rechargeable AA battery (NiMH or NiCad) that might work. You're not going to get much power from that size array anyway, especially if it is not in full sunlight. A Farad (F) is ,000 times bigger than a milliFarad (mF), which is ,000 times bigger (stores ,000 times more) than a microfarad (mF). pF and nF are so tiny do not even look at them. With your size array voltage might not be a problem, but be sure to check that the voltage rating of the capacitor is less than whatever the array can make. Some people buy those solar yard lights, which seem to break often. You might be able to get some and use the contents for your project (pre-wired circuits).
Q:Can solar panels be installed in a desert environment?
Yes, solar panels can be installed in a desert environment. In fact, desert regions are highly suitable for solar energy generation due to their high levels of sunlight and low cloud cover. The dry and arid conditions in deserts also help in reducing the maintenance and cleaning requirements of solar panels.
Q:I need a solar panel for my laptop as i am going camping in the desert, and i need my laptop. There are two choices of solar panels, One is 0 watts and 2 V and maximum power current 0.56 amps. The other one is 2 watts, 2 V and no mention of current. My laptop plug says input 00-240V and .5A and then output 5V-5A. Which one should i get for my laptop. If there are other choices please tell me ill look them up on OKorder.Thanks
I'm afraid neither of these panels will do much for charging or running your laptop. If the power brick is supposed to emit 5 volts at 5 amps, that's 75 watts. Neither of those panels provides enough voltage and the power output is obviously far too small. The capabilities of solar power are vastly overestimated for small panels. Sunlight is limited to about kilowatt per square meter under ideal conditions (summer time, clear blue sky, for a few hours around noon in the US southwest). But consumer panels top out at about 5% efficiency, so your limit is 50 watts per square meter - in other words you would need about half a square meter, or about six square feet, of panel to provide 75 watts. And even under ideal conditions you will only get that much for a few hours each day. Also, the panel's voltage output is not regulated, so even if you find a panel that emits 5 volts (this would actually have to be made up of groups of 30 cells in series, as they emit half a volt each at most) you can't just connect the panel output into your laptop's DC in. You'd need a regulated DC-to-DC supply, and since that is not 00% efficient it will cost a bit of the power... now you need even more panel area. All in all, not really a practical thing to carry along on a camping trip.
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.
