- Q: Hi.How efficienent are solar panels? I mean, suppose we install a kw panel.. Wil it produce 5kw in 5 hours of good sun light?Or like if its 80 percent efficient, wil it produce 4kw and so on.Also, do the chinese solar panels give the same results as compared with panels from other countries?I live in india, so we get plenty of sunlight during the day.Thanks
- Efficiency of photovoltaic panels usually describes the ratio between the energy of the sunlight falling onto the panels and the electric energy you get out. This number is, for commercially available panels today, usually in the range of 2...9 %. What you are asking is something else. The power from the panel depends on the light falling on it. A panel rated for kw peak will deliver that kw under a clear sky, with the sun orthogonally above the panel. For a fixed mounted panel, that is true (at most) for two days every year at noon. At any other time, the output is less. Therefore (at least for the area I live in), some people build databases (and Excel tools) in which the various variables are considered: - inclination of the panel - orientation of the panel - average sunshine duration during a year Plugging in these numbers, I get theoretically for my roof an electricity output of just over 000 kWh/year per installed kWpeak of collector power. If you set up a tracking panel (following the sun), the energy output of the panel will be higher, but so will be the cost for the mounting and the area needed to set up the system.
- Q: Why can not the solar panel load directly?
- Power supply must be a number of individual battery strings, connected in parallel and tightly packaged into components.
- Q: I would like to know of any construction companies, road crews, or any company that uses solar panels in the Tampa area and throws them away. I like to recycle solar panels by repairing and processing what power I can from them. Know any companies that throw out used solar panels? If so, can you provide the name and number?
- Test the battery. Connect the positive and negative terminals of the battery to the positive and negative probes of the voltmeter. If a voltage is read, the battery is still good. Remember, however, that this is a rechargeable battery, so if it is dead, it can be recharged.
- Q: Photosynthesis is fairly inefficient, but efficient enough to power all life on earth.
- One of the primary reasons solar cells are made of silicon is that the bandgap energy of silicon happens to be nearly equal to the energy of visible light, which is the major portion of energy emitted by the sun. Therefore, silicon is the ideal substance to fabricate solar cells with.
- Q: Me and my wife just saw an ad on TV about going solar and saw the money we can save every month... any here have solar panels? How much do you save every month on energy bill? Is it true that your energy meter will spin backwards? lol
- I have them. Jamie's way of going about it is one way, the other way is to do-it-yourself. I went the DYI way and got off the grid. I bought my panels online along with the batts, they were cheap. I paid cash on the spot, this allowed me to not get into paperwork and possibly financing it. Now I save what I was paying every month. I am not interested in the meter going backwards and selling my power, I am free now!
- Q: It measured volts before I attached it, and after attaching the voltage regulator device, the voltage dropped down to 3 volts, even when just measuring the difference in the solar panels nodes themselves, suggesting that the entire panels voltage dropped and not just the voltage in the regulator. I tried testing it with a power supply of 7 V 0. A and it works fine, but I don't know why it won't work for the solar panel.
- you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
- Q: Can solar panels be installed on a restaurant or food service establishment?
- Yes, solar panels can be installed on a restaurant or food service establishment. In fact, many businesses in the food industry are turning to solar power as a sustainable and cost-effective energy solution. Solar panels can be mounted on the roof or other suitable areas of the building to generate clean electricity, reducing the establishment's reliance on traditional power sources and lowering energy costs.
- Q: if i was to put a solar panel (sp) just outside of the earths atmosphere ans another solar panel (sp2) 0km away towards the sun. which one would generate more power (sp or sp2)? and how much more? is there a ratio to work out the power output and distance from the sun? would the 0km distance between the panels make a large difference in power output?many thanks in advance
- there are hundreds of satellites in area with image voltaic panels, yet none of them are designed as ability stations. Transmitting ability employing radio frequencies may be profoundly inefficient. A string of satellites orbiting the Earth may be quite costly. despite if image voltaic ability have been to realize financial viability, we would positioned them on the floor the place shall we use them. Given the quantity of stepped forward renewable components of ability already being developed there is quite no reason to launch a ability plant into area. Wow - watched the youtube video... it quite is conceivable the worst invention ever and that i'm hoping it by no capacity catches on. the final situation we prefer are retards who're too lazy to plug of their telephones dropping electrical energy on rather inefficient on the spot circulate while many aspects of the international are dealing with ability shortages. universal chargers are already undesirable adequate simply by fact they consistently drain electrical energy even while not in use. i'm surely not an environmental saint yet this situation is in basic terms stupid.
- Q: Does any one know how to make a solar panel or a type of Alternative energy maker. Best answer gets 0 points

- Q: Can solar panels be used in areas with high levels of seismic activity?
- Yes, solar panels can be used in areas with high levels of seismic activity. However, proper installation and design considerations are crucial to ensure their durability and structural integrity. Reinforced mounting systems and flexible connections are typically employed to allow for movement during seismic events and minimize potential damage. Local building codes and regulations should be followed to ensure the safe and reliable use of solar panels in such areas.
