Q:how much do solar panels cost?
The silicon ones(last 5 to 25 years) run about $4-$5 a watt the amorphous (thin film) a little less (may last 5-0 years). If you use megawatt hour (000 kilowatt hr) a month you will need at least 3000 watts minimum. Therefore if your electric is .0 per kilowatt hr( $00 per month) the payback is around 25 years once you add the batteries plus inverters(batteries $50-$00 each)(synchronous inverter $3000 to$20000)(ie $5.00/.0=50 months at optimum output).Figure (depending where you live) probably only 50% so break even is usualy about 20 yrs.Ie you pay 20 years electric bill and hope nothing breaks(insurance not included) then you can start saveing money.
Q:Question about Solar Power and Wind Power?
A 000 sq. foot abode isn't very great whilst it includes the standard length abode. at present the main inexpensive and best variety of eco-friendly potential for powering a house is wind potential. an outstanding wind turbine can get you on the brink of seventy 5% to a hundred% or much extra performance. extra beneficial potential produced via wind will reason the electrical powered meter to run backwards. At that factor, you're promoting the surplus electrical energy decrease back to the electrical powered company, providing you with extra money in the direction of a destiny electric bill. in spite of if image voltaic potential can help, image voltaic potential, in itself, might fee 2 to 5 cases extra beneficial than wind potential.
Q:How many LED's can I hook up to my mini-solar panel?
Typically LED's run off low voltage and 20mA or so of power (it depends what kind of led you have). That being said if one of your solar panels only provides 22mA of power then your circuit would have to be a series circuit for you to connect more than one. In a series circuit the current supplied of 22mA will go through each LED whereas a parallel circuit the current would be divided for each subsequential led. So in your case i can see you getting away with 3 or so led's before the voltage drop across each led will cause the voltage to be insufficient enough to drive anymore. Keep in mind the LED's will turn on but the first one will be bright then next one not as bright and so on. If you opted out and bought a solar panel with 200mA and 4V you could wire the led's in parallel and get 0 led's to turn on with the same brightness or intensity. Hoped that helped!
Q:I will like set up a solar panel to cut down my eletricity cost in Cameroon.can you allocate me a supplier?
good idea going solar, i would suggest doing a google search, as their are many suppliers. then you need to calculate the amount of wattage you think these apartment houses are going to require. volts x amps = watts. if you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. you could even have a generator for emergencies if you go off the power grid. on final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. it will tie in to the existing electrical system in the apartments. i know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. the companies are profiting from this so i would suggest looking for a supplier in germany, first. they may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. i wish you success!
Q:solar panels and calculations?
The okorder.com The reference section has all the formulas you are looking for and there is a list of dealers by state, plus various state rebate information. Yes, you can hook up different panels to the same system. There are special controllers that regulate the voltage. I'm more of a hands on nuts and bolts guy so I can't help you with the formulas and engineering explanations. Another great place to get information is Home Power Magazine. You can get the issues online or in print. Thanks for going solar!
Q:Any help financially to buy solar panels?
I don't believe that there is any help yet.
Q:solar panel environmental affects?
I wouldn't worry about what the solar panel is going to do to the surrounding environment, I would worry about what the surounding environment is going to do to the solar panels.
Q:Advantages and Disadvantages of using solar panels?
benefit: 0 value for the source of power No by way of product draw back: Unreliable extreme value to purchase image voltaic panels. Now once you're speaking approximately actually in basic terms utilising image voltaic power i.e. letting water sit down outdoors until the solar warms it up... Then I see no actual benefit to it as a results of fact it will not at all have the skill to warmth water on your needed temperature and it will take way too long.
Q:Is it worth getting solar panels fitted on my roof?
View okorder.com/. Too expensive and it may be illegal.
