Q:How do home solar panels integrate into a houses current electricity?
Light striking a silicon semiconductor causes electrons to stream, making power. Sunlight based force producing frameworks exploit this property to change over daylight straightforwardly into electrical vitality. Sunlight based boards (likewise called sun powered modulese prepare immediate current (DC), which experiences a force inverter to get rotating current (AC) — power that we can use in the home or office, in the same way as that supplied by an utility force organization. There are two sorts of sun powered force creating frameworks: matrix joined frameworks, which are associated with the business power framework; and stand-alone frameworks, which encourage power to an office for prompt use, or to a battery for capacity. Network joined frameworks are utilized for homes, open offices, for example, schools and healing facilities, and business offices, for example, work places and strip malls. Power produced throughout the daytime could be utilized immediately, and in a few cases surplus power might be sold to the utility force organization. In the event that the framework doesn't produce enough power, or produces none whatsoever (for instance, on an overcast or blustery day, or around evening time) power is acquired from the utility force organization. Power preparation levels and surplus offering might be weighed continuously on a screen, a compelling approach to gage day by day vitality utilization. Remain solitary frameworks are utilized as a part of a mixed bag of provisions, including crisis power supply and remote force where conventional foundation is distract
Q:Tips for convincing my school to put solar panels on the schools roof?
Unfortunately installing Photoelectric Solar panels on your school would probably cost more than the entire school budget. In order to make this sort of proposal you would need to have some hard numbers to show exact dollar amounts of costs and benefits. You would need multiple quotes from companies that install solar panels and information from the electrical company that would have to tie the system into their grid. This is a HUGE undertaking. If you really want to reduce carbon emissions, suggest ways to reduce the energy use within the school instead of converting to solar. Better windows, doors, and roof insulation. If you have a leaky roof, fixing that would get rid of water damage and better insulate the school thus saving energy. Suggest plans to reduce electrical usage like having computers go into Hibernate mode after 0 minutes, turning off lights in rooms that aren't getting used, etc... Many people are fooled into thinking that solar power is this awesome free energy source. IT is NOT. Solar panels are great for powering small items or for getting power when you have no other way of getting connected. However it takes MORE electricity to create a solar panel than the solar panel will ever produce in it's ENTIRE lifetime. Do some research into the production of silicon crystal and semiconductors and find out how solar panels are made. Until the technology improves greatly, solar is not a green power source other than generating money.
Q:Why only Photo-Voltaic solar panels?
Solar thermal systems aren't really that much cheaper. You have to have complex systems to pump the water, heat exchangers, regulate the temperature in the panels so it doesn't get too hot, regularly inspect it for leaks, have a system to maintain a constant output temperature, etc. The return on investment of such systems are usually very long, on the order of several decades, even for very large buildings. If they were cost competitive with traditional heaters then they would already be much more widely used I think. Plus with solar thermal you have the unfortunate reality that technologically they aren't going to get much more advanced. That's probably not the case for PV panels. So the only way I can really see solar thermal being used on a larger scale would be some kind of subsidy. PV on the other hand may have a breakthrough tomorrow that drastically reduces its cost. I'd be curious to find out how well those solar AC units actually work though, I can see how they might have potential.
Q:Solarcity free solar panels?
Remember, if it sounds to good to be true, it usually is .
Q:how can you make your own solar cells for solar panels?
I don't have an idea but would surely refer you to a website where you would surely find information on solar cells and many more alternative energy questions.
Q:how do solar panels work?
The term solar panel is best applied to a flat solar thermal collector, such as a solar hot water or air panel used to heat water, air, or otherwise collect solar thermal energy. But 'solar panel' may also refer to a photovoltaic module which is an assembly of solar cells used to generate electricity. In all cases, the panels are typically flat, and are available in various heights and widths. An array is an assembly of solar-thermal panels or photovoltaic (PV) modules; the panels can be connected either in parallel or series depending upon the design objective. Solar panels typically find use in residential, commercial, institutional, and light industrial applications. Solar-thermal panels saw widespread use in Florida and California until the 920's when tank-type water heaters replaced them. A thriving manufacturing business died seemingly overnight. However, solar-thermal panels are still in production, and are common in portions of the world where energy costs, and solar energy availability, are high. Recently there has been a surge toward large scale production of PV modules. In parts of the world with significantly high insolation levels, PV output and their economics are enhanced. PV modules are the primary component of most small-scale solar-electric power generating facilities. Larger facilities, such as solar power plants typically contain an array of reflectors (concentrators), a receiver, and a thermodynamic power cycle, and thus use solar-thermal rather than PV.
Q:help understanding solar panel stuff?
Here is one that can work for a small swamp cooler, but if you want to build a larger one, use multiple fans. This model uses .4 amps at 2 volts DC. 2 X .4 = 5 watts. You'll want about 6 watts per fan for the panel, so if you had 4 of these fans, at 5 watts each, look for a 25 watt or so sized panel. The panel should have a Volts Open Circuit (Voc) rating around 8 volts, that is normal for a 2 volt system. Then you can just wire the fans, in parallel to each other, to the output of the panel. I read an article in Home Power Magazine about a guy who did this to ventilate his crawl space. He only wanted the fans to run when it was dry weather outside, like when it's sunny. The panel not only powered the fans, but were perfect for sensing when it was sunny. You can do the same thing with the swamp cooler. This fan was clipped from Marlin Jones website, they sell small electronics and such, the link is below. They do not sell solar panels, but I've found OKorder to be a great source for them. We have two small arrays here that run LED lights in parts of our home, and charge cell phones, ipods and small electronics. Take care Jorge, Rudydoo
Q:Where can I find low power solar panels?
My suggestion is to first make sure that your calculator does not also use a tiny button cell. It could just be that the battery went dead. Also know that it's probably less trouble to just get a whole new calculator. If you have the skills to replace the solar cell, I'd suggest first disconnecting it, and wiring a .5 volt battery in its place. If that doesn't work either, maybe the problem is not the solar cell at all, but just its connection, or even a dirty ON button. As for where to get a replacement solar cell, if it were me, I'd go to a dollar store, and see if they have a cheap solar calculator that I could harvest one from.
Q:Would you put solar panels on your home? and why?
If your house was not built to include solar panels, it may encounter problems that most people do not consider. For example, your neighbor may plant trees nearby and they could shade your panels. Your house may not have good alignment with the sun, so your net hours of sunshine may be too small. If your local planning folks allow panels and your house is oriented properly to the sun and no trees will block the sun, I suspect it will be a good investment long term. Still the up front cost is high. I feel that common folk like myself would be better served if we could buy shares in our local power company by purchasing a number of panels ... offered and installed by them ... and that we would then get a net monitoring of both our own electrical use and a reduction on our electric bill for the portion of our investment. That way, it seems we could each make a small investment in solar and add to that investment as we earn more money ... and essentially eliminate the need for new centralized power plants. How many malls does your city have that are completely empty and could be returned to the community as a mini power plant site. My city is loaded with malls that nobody uses anymore. Businesses move and and fail because nobody goes there. They go to the new more sexy malls. Several of these outdated malls have power lines running directly through their empty parking lots. Why not have community solar investments in these sites? Every building could include solar panels and the entire parking lot could be covered with panels. The inside of the building could still be used for other routine purposes. The local power company would be the perfect organizer and maintainer. This way solar would not be so expensive. The cost would be shared by many and so would the rewards.
Q:where do you get little solar panels?
You could build them yourself? Depending on the time you have.... They are having a special at the moment....
