Q: Rooftop solar panel (not sure if rubber or plastic?) has leak arising from thin vertical crack in panel about long. Any ideas for repair?Thanks.
Depending on the material and operating temperature of the panel, it MAY be possible to fix it very simply and easily by applying Hot Glue Gun adhesive over the cracked area. The high temperature glue gun adhesive melts at approximately 60 degrees Farenheit, and if the collector temperature does not quite reach, or exceed that operating temperature, then that repair method should work. Another possibility is an aerosol spray can product called LeakEnder. This is usually available at your local hardware store, or the major home improvement centers [like Lowe's, Sutherland's, Home Depot, McCoy's, etc.]. After preparing the area to be patched by cleaning, you just spray the LeakEnder patching material on the crack and an eighth of an inch or so around. IF the operating pressure or the collector is very low, it MAY even be possible to patch the leak with nothing more than a narrow strip of DUCT TAPE!!!!! Another possibility, but unless carefully accomplished is to weld the crack with a Soldering Gun and some scrap plastic from packaging material. The problem with this fix is that you must be very experienced in application of heat from the Soldering Gun, OR you will melt a larger hole in the collector tube than the crack was. Regardless of patching method, it is CRITICAL that the cracked area to be patched MUST be CLEAN and DRY BEFORE applying any patching material. Good luck!
Q: What things can a solar panel power?
What things can moving water power? It just depends on the size and number of panels.
Q: I jotted down some notes for my Technology and Architecture class and I'm trying to figure out what i meant when i said 'Treated with gases at extremely high temperatures.' I have NO idea what I was talking about :) Im trying to figure out if what I am talking about is about Silicon, Polychristaline, or a Solar Cell/Panel.
Some steps in making semiconductors use gases at very high temps, and solar cells might.
Q: i hav e a project for school we need to calculate cost to buy and install solar panels in our school
It operates itself, except if there is a problem. It costs a lot to buy and setup. Some solar panels move to track the sun- the tracking equipment is complicated and needs maintenance. Some solar power systems have banks of batteries to store the energy- those wear out eventually. Some solar panels feed into the power grid, and there is a cost associated with managing that power- paid by the power company.
Q: How much energy can solar panels generate?
The amount of energy that solar panels can generate depends on various factors such as the size and efficiency of the panels, the amount of sunlight received, and the geographical location. On average, a residential solar panel system can generate between 10 to 20 kilowatt-hours (kWh) of electricity per day. However, larger commercial or utility-scale solar installations can generate significantly more energy, sometimes even in the megawatt range.
Q: I want to know how to hook up a Solartech SPM020P-R, 20W Solar Panel to a single outlet that you can but at a store.
That panel you reference puts out about 20W. @ 8V of DC. You can't wire that to a standard 20V outlet without a battery/inverter unit. Even then, you don't get a useful amount of power. In a full day you would collect enough energy to run a small TV for about an hour.
Q: all i want to do is provide enough electricity for 2 fluorescent bulbs i was looking at some 80 watt panels how many of those would i need and what else do i need for storing the electricity for use at nite? and how much would it all cost?
The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.
Q: Can solar panels be used to power streetlights or outdoor lighting?
Yes, solar panels can be used to power streetlights or outdoor lighting. Solar streetlights are becoming increasingly popular as they provide a sustainable and cost-effective solution for outdoor lighting. Solar panels capture sunlight and convert it into electricity, which can then be stored in batteries and used to power streetlights during the night. This not only reduces dependence on traditional energy sources but also helps to reduce carbon emissions and overall energy costs.
Q: Main questions: How can I work out the efficiency of a solar panel and how can I work out if the panel is relatively cost-effective? Also what type of solar panels is considered most effiecient?Let's assume that all relative values are available.Secondary question: What type of safety regulations and licenses are required to be fulfiled in order to import solar panels into the EU from non-EU countries?
366 W/square meter on March 2 and tweaked based on lattitude eff = W out/Sun W in there are special heat meters to measure W in ======== IEC 62688 Certification; and UL cert in USA
Q: i took some solar yard lights apart and put them together in a series. i was told if you take AMPS times VOLTS = WATTS. do you test it with ac volt or dc volts? I tested mine with dc volts and got 4 volts in good sun and had my meter set on Ma or milliamps and got .83 which i am asuming that is .83 of one amp now i took those and multiplied .83 times 4 volts to = 34.03 watts. Is this large enough to charge a car battery in a day? And doese it make a difference for amps on how fast it charges or watts. i also was looking around and found 30 watt panels but had higher amps. I am very interested in building solar panels but i realize i dont know what i need to do to make shur they are big enough. my panel is only 9inch by 0 inch. It seems weird that i am putting out 4 volts
If a car battery contains 50 amp hours of charge at 2 volts, that's 600 watt hours of energy. divided by 34.03 watts, 7.63 hours to charge completely in direct sunlight. You don't want to connect them all in series. You want about 4 or 5 volts to charge a 2 v battery, so you should connect groups in parallel, and connect those groups in series to make your voltage. You'll end up with the same amount of power, lower volts and higher amps. It will work for trickle charging your battery if it's not too far run down.
