Q:what is one benifit in a solar panel?
what do you want to know ? there is so many benefit of the solar panel , such as no pollution , ETC
Q:Solar panels with snow?
If you have an electrical backup you could install something to melt the show where the solar panels are installed. You might try installing them near a fireplace chimney if you have one. My thinking tells me if you have a clear raised bubble or pyramid over the panels it might help.
Q:Can a solar panel work with an inverter?
Solar panels output a very small amount of current. Even though you're getting 2V from the panels, you aren't getting enough amperage to power even the inverter itself, let alone anything plugged into the inverter. Car batteries are able to be used with inverters because they can crank out enough amps to power the inverter and whatever is plugged into it. Inverters only step up voltages and change DC to AC. They do not increase power (wattage) potential. If you want to plug in a 20W appliance into the inverter, the 2V source must be able to deliver 20W of power regardless of voltage. In pretty much everything solar powered, the panels are used in conjunction with batteries. The solar panels slowly recharge the batteries. The batteries are where most of the power comes from. Nothing is driven directly from the solar panels themselves unless the power requirement is low enough, such as a calculator. Solar panels will have an output rating in watts (W). If the wattage of your inverter plus whatever you plug into it is lower than the panel's output rating, then it can power it directly, provided you have 00% light input into the panel.
Q:adding more solar panel & battery?
You can wire solar panels in parallel (i.e. positive to positive, negative to negative). Preferably, the panels should be similar to allow the output voltages to track. Otherwise, it may be necessary to include diodes in series with each panel so voltage variations do not have an adverse effect. The other alternative is to have the panels charging individual batteries and then combining the batteries through diodes before using the inverter. This approach would require separate charge controllers for each battery. Not quite as energy efficient as each diode causes a voltage drop (and so a power loss).
Q:Please differentiate b/w mono & poly crystalline silicon solar panels.?
these solar panels are named different based on the solar cells used... mono-crystalline solar cells: As the name suggests, each cell is made from a slice of a silicon crystal, which is made by purifying, melting and freezing silicon. pol-crystalline solar cells: these are a slight variation of single crystal solar cells. they are made of slices cut out of blocks of several silicon crystals, as opposed to single silicon crystals. check the link below to see other differences between the two types (easy to understand), such as their prices and efficiency levels. there is also a third type of solar cell/panel called amorphous solar cells.
Q:Properties of solar panel?
Q:Can one benefit from solar panels?
In theory, yes. But the fact that nobody is doing it implies there is something wrong with the idea. Solar panels are not exactly new.
Q:45 Watt Solar Panel Kit Harbor Freight?
Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:Solar panels........................?
Solar panels are one of today's best investments! With a lifespan of 25 to 30 years minimum, and a payback period of 0 year or less, the economics are a no-brainer. There are often state loan programs giving you low interest or no interest for a length of time. There are also tax credits and rebates that take care of a lot of the up front money. Calculate for yourself what you will pay to your utility over the next 30 years. Then see how the cost of a solar electric system compares. My company has helped scores of homeowners and business owners claim Independence and take control of their energy costs for the next few decades. Contact us to have a site evaluation and payback analysis for your particular situation.
Q:Are Solar Panels worth it in Southern California?
There are several factors to consider when looking into solar power for your house. If you want to replace your use of utility electricity with solar power for say a 500 - 2000 square foot home then the system will cost you at least $30000 - $50000 to install. You will also have the maintenance issue of your storage batteries, panels, and inverter which will eventually wear out over time. So lets say we have an optimistic price of $30000 for a whole house system (this would be really cheap), dividing this by your yearly consumption would give you the amount of years it would take for the expenditure to pay for itself (not counting maintenance which could be costly). The payoff would be about 25 years, so all things remaining equal, I would say that it is a bad investment. Solar panels as they are manufactured today do not have a very long life span. They will greatly decrease in efficiency after several years and will most likely need to be replaced in 0 years. The panels themselves are the greatest expense. You could problably find better ways to make/save more money by investing $30000 - $50000 somewhere else IMHO. Solar technology is still not at the point where it is profitable in the sense you are thinking about. Unless of course, there are huge tax incentives for you or large rebate programs through your local utility, but you would have to do the math on that as well. If you are thinking small as in a couple panels to supplement your utility electric, the above still applies as well. In fact will it take longer to recoup the cost of a smaller setup. Hope this helps!
