Q:What makes solar panels Inneficient?
figure it out for us
Q:What happens if I put a 00v, .5A solar panel on a 2V, 450cca Gel deep cycle battery?
The solar panel is capable of /2 Amp output. If you hook it to a 2V battery directly and the battery is discharged it will want more than /2 Amp and pull the voltage down until the battery is charged to a certain level. Eventually the battery will try to charge up to 00V which will definitely damage the battery. If you use a regulator circuit running off the solar panel that outputs 2V then you will have a constant voltage circuit which will still be limited to /2A or whatever the regulator is capable of outputting. Of course you can't just go out and connect 00V to any voltage regulator it has to be capable of running from 00V and dropping the voltage to 2V like the original charger that comes with the battery. The same explanation applies to a 72V battery. You have to limit the output voltage to 72V or risk overcharging the battery.
Q:Need Help, 2v Solar Panel for Emergency?
Most radio's have a DC plugin port. You can build or purchase adapters that step down the 2 V power to the radio's power needs. In short, power your devices directly from the solar cell using the car adapter plugs made for them or charge a larger battery as a power resevoir and plug your car adapters into it when it is dark which allows you to charge devices when you are not using them while sleeping.
Q:Chem question regarding using solar panels ....?
It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
Q:Solar panels and your opinion?
The payback is usually between about 5 and 5 years depending on how expensive electricity is in your area, the rebates available, and where you live (is it sunny most of the time?) Most people that get them don't do it for the investment - they do it to be energy responsible - but it's not a bad way to do both if you have the money to put into it. I personally just pay for the green energy option from my electricity provider. So I am buying power from solar and wind farms, and it cost about 0% more per month. I don't get the benefit of free power, but it comes with a smaller price tag initially, and I think when we all invest in these technologies, the price will improve over time, so energy costs will be lower in the future.
Q:Questions about the solar panels?
Are there any extra unseen costs? (tools, energy converter, ect). Yes. Batteries or Inter-tie, charge controllers, inspections, wiring, inverter etc. 9. How much is it to get an electrician to hook you to the grid? Call for a quote. 0. Is it better to hook to batteries or the grid? Pros, cons, why? Batteries are expensive and only last several years. Maximum power is limited by the size of the inverter. Grid-tie eliminates the need for batteries but then you have to purchase a very expensive grid-tie inverter.
Q:Are solar panels efficiency already calculated in their power rate?
If it says STC or Standard Test Conditions on the nameplate or documentation, then that means 80 watts under bright sun at an unrealistically cool temperature. It is rare to see that power in real life, except when the perfect storm of conditions come together. There is also a PTC rating for some panels, which is more realistic. If the panel does not say STC or PTC, the manufacturer is free to make up whatever test they feel like, which generally leads to ridiculously overstated power. As for efficiency, for residential panels, that's generally only of academic interest. A 80-watt panel is 80 watts, regardless of the efficiency. A more efficient panel will take up slightly less space, but most people are more interested in the total price, since roof space is generally not an issue.
Q:Why are solar panels so expensive?
The only way I know of is to invest the money in the stock market. Most savings accounts only pay 3% intrest. While stocks float and if you don't know what you are doing you will never make as much money as you could save on your electric bill. Then the fact that you have to pay the electric bill out of the money. In the end you rented electric and can never get your money back. You can always sell the solar electric system and get your money back plus a profit. Not many people live in the same house even 20 years so it will sell. Toss the coin. It is what ever is best for you.
Q:Buying inverter for a solar panel?
I'm guessing that each of those solar cells is just 0.5 volt at max power, so if you make a 2-inch square panel, you will get 2 volts - not enough for the inverter. A car inverter is notoriously inefficient, but it would work if you connect it to a 2-volt battery. You cannot generally connect such an inverter to solar panels alone. The battery supplies the peak current that the inverter needs, and the panel charges the battery. To charge a 2-volt battery, you will want 36 cells, generally, which give you an 8-volt panel. You can buy an inexpensive charge controller somewhere. If your laptop will run off 2 volts directly, you can skip the inverter and be much more efficient. Or if the laptop runs of (say) 9 volts, you can use about 40 cells to get 20 volts, get the proper power plug from Radio Shack, and plug the panel directly into the laptop.
Q:How solar panels and furnaces work?
Well solar panels conduct electricity from the suns waves and turns it into dc current then it is either put into a grid tie inverter to change it to AC and it makes you meter go backwards instead of forwards. or if its not a grid tie inverter it is just put into batteries as dc then changed into AC from the inverter and then used for household appliances. nothing really does run on DC that is why it has to be changed. and for solar furnaces if you mean a water heater that works by a substance here in Pa its antifreeze is heated up by the sun in the panel it is in a continous loop and that is what gets heated up the water then flows over tow of the tube that contains what ever substance such as antifreeze and heats the water.were the water and the tube that changes the water from cold to hot is called the heat exchanger. the substance is actually get heated first then the water. solar heating for water accounts for 29% of water heating in the us. Now if you mean solar furnace as in passive solar thats completely different because here in Pa if we want it our houses have to face to south to get the suns rays. (alot more windows) and there is a cement slab placed only on the south side of the house and it has insulation covering it. There is a certain type of glass that is used for this that will allow the suns rays to come in and let the heat in for the summer and also for the winter. the main place for that would mostly be the first floor of the house due to the height of the windows and the angle of the sun(pa in the summer is 73 degrees and in the winter its 27 degrees) thats when the second floor would be ok to heat the rooms. Hopefully i helped and i explained it in a way that you can understand.
