Q: Can solar panels be used in areas with high humidity?
Yes, solar panels can be used in areas with high humidity. While high humidity may affect the efficiency of solar panels to some extent, they can still generate electricity. The performance of solar panels in humid environments can be optimized by using materials that are resistant to moisture and by ensuring proper installation and maintenance.
Q: I remember hearing somewhere that solar panels may attract light rays away from plants thus having a potentially negative effect on the plants. I can't remember where I heard it but I'm curious if there is any truth to it.
if that were true, then anything that absorbs the suns rays do the same thing. Doesn't make any sense to me.
Q: This is the cenario. Your yearly energy use comes by mail and it states that the total amount of energy used your household is 7000kWh.Then you make the decision of switching to get solar panels. The question is what area should your solar panel be given that the average annual length of daylight is 2.0.
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: can u use a light bulb instead of the sun to power a solar panel
Yes, but why? If you've got the light-bulb, you've already got more electricity than you will get out of the solar panel.
Q: I know what they do and how they work, but at this point they're expensive, don't always produce enough electricity as needed, and can't be used when there's no sun, as in half the day. Wouldn't wind power seem so more efficient? Or if they do use solar panels, how about putting them in the desert. But I really believe that research money should go to fusion generators since that's the future and the answer to our problems. Which is best in your opinion?
There is not a yes or no answer. But for the majority of the population it is a definite no. Because the energy needed to make a solar panel is more than the energy that a solar panel can return in its life time. so No for cities and urbanized areas because there is already existing infrastructure therefore you'll be wasting more energy getting them installed. And it is better and more efficient to have the more common energy sources for populated areas. However that being said it would be more efficient if you live in a remote area as it would not be worth it to build a huge electricity grid just to power one small house in the middle of no where.
Q: Someone Said It costed them 50,000 To Install Solar Panel In their House and 35,000 For Installation. Is that true?
It costs more than they will ever save you in electricity cost.
Q: I am in the market for buying a home. There is one for salke that actually has solar panels on top. How are they used? Do you need to pay for gas and electric still. Does it really light up the house and keep it warm. WHat about the AC keeping hte house cool in the summer does it work for that too? Please explain in solar for dummy terms. I haveno clue about solar panels other thatn the fact that it needs sunlight to run.
Okay--here it is (without the techie buzzwords!) Solar power has a start up cost--the panels and related equipment. But the amount it cost to operate is virtually zero--pretty much jsut servicing th equipment o keep it working properly--much as you do any other appliance. How much electricity you will still have to buy depends on four things: a) how much your system can produce. If you have a 4000 watt system, you'll still buy a fair amount of power. Abigger one--and you will need less from the power company b) how efficient you (your home and appliances are). The more efficient, the less electricity you use. Obviously, things lie CFL bulbs are very helpful here c) Are you willing to invest in a battery storage system to store electricity from the system for use at night? Right now, that's still pricey. But these are starting to come on th emarket more. If you aren't ready to do tha tnow, you can always add it in later. d) can you sell excess power back to the power company.? In California, the law requires utilities to do this--but its not a universal yet, so it depends on where you are. How this works: you are still hooked up to the power company. Any time you need more power than the solar system produces, yur system jst draws it off the power grid--jsut as always. But--any time you are using LESS than the amount of power your system is producing, the excess automatically feeeds back into the electric grid and a special peter credits you with the power. There are cases wwhere people have goene on a long vacation in California and when they got home, the power company owed them several hundred dollars! You'll need to do some research, price thngs, take your own lifestyle into account, and decide what the best choices for you are. It sounds complicated--and to an extent it is. But the reason is tha tyou have a lot of choices tha tyou can make work to your advantage, instead of jsut writing a fat check to the power company every month!
Q: Actually I want to convert my home electricity on Solar Panel to cut down electricity costI have 2 AC's, a refrigerator, 3 Television, 2 Computers, 4 Fans etc
good okorder lots of good ideas there
Q: How much would it cost (approximately) to convert my home (3 bed. 2 bath) to a green home that is run entirely upon solar panels on my roof? From the panels through installation does anyone know a price break down?
Check your electric bill, and see how many kilo watt hours you have been using for the last year. That will give you a clue as to how many panels you will need in the array,and how many batteries you will need, what size inverter is needed plus would you want a true sine wave or modified.And that's just for starters. But of course you might get a break from your electric Co.(Rebate) also from your state,and possibly something from the Feds. I have installed on the travel trailer a 25 watt panel($850) a 22amp.charge controller ($45) a pair of Trojan 425 watt 6 volt batteries ($300 each) and a 2000 watt inverter modified sine wave ($2000).The only thing I can not run with this set up is the A/C which requires 3000 watts of power. So as you can see your project could get very expensive. I hope this sheds enough light on the subject for you.
Q: I was just wondering what the minimum and maximm charging voltage and ampere is for li ion batteries. If i connect a solar panel, which only gets enough sunshine to generate voltage, will that still charge the battery, or would i have to series connect solar panels until they together reach 3,7volt?
One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .
