Q:should i get a solar panel?
Solar panel is one of the best sources nowadays to generate electric energy using the sun rays that comes from the sun. But, this set can be so hard to find and it’s very expensive to buy.
Q:Is it worth getting solar panels fitted on my roof?
In 2007, the cost of solar photoelectric power was 38 cents US per kwh while the cost of coal power was 0.6 cents per kwh but consumer costs for power were 2 cents per kwh as additional coal power plants are not being built so wind and natural gas are being built. Without government incentives, solar power are not economic. However, the UK has extensive subsidies for solar, I would suggest that you learn how to perform Internal Rate of Return ( IRR ) calculations and Net Present Value ( NPV ) calculations to evaluate your financial decision, excel has an excellent =XIRR() function to do this with. Most people talk about payback periods but that's due to the poor level of financial education in the population and payback periods don't give you an appropriate evaluation of the time value of money. With solar power, it's a razor thin line of economics so you have to get the calculations right to know what's in your best interest, the laymen hearsay isn't going to do it.
Q:How can I power 5v or .08 amps in a remote loaction via solar panel.?
Search the web for some of the inexpensive solar Cell Phone Chargers. They can be hooked in series or parallel as needed to get you teh voltage and current needed. The 80mA is not too tough, thats not much current. Suggestion is to use a battery that is constantly trickle-charged by the solar panel. This will assure operation on a cloudy day or at night. Another strange source for solar panels and solar charge systems is, believe it or not, Harbor Freight Tools. they are on the web as well as have stores all over.
Q:Solar Panel experts...please help.?
I'm not an expert, but I recently went through the process and now have a system on my home. I got 3 quotes from 3 licensed contractors and they all seemed to be about the same, the prices seemed to be based on the amount of energy they produced. In CA and I'm sure everywhere else they are tested by an independent agency which rates the output of the panels. You seem to have similar usage as my house, I got a 3.75kwhdc unit, it isn't expected to eliminate my bill, but it should reduce it by quite a bit. I've only had it for a few months and it took me from about 45 kwh per day to around 0. I know I'll have lower output in the winter, but my usage is lower in the winter as well. I decided on this size unit to maximize my rebates and I can take advantage of my utilities rebates when I add to the system in a few years. The difference between panels seemed to be how big they were. Some systems can be twice the size and produce the same amount of energy. I put a couple links below that I found helpful. The roseville pv buy down program has some great links that give information about specific systems.
Q:Why aren't electronics made with solar panels?
Cost and and it would be inconvenient to the consumer in this Gotta have instant gratification society. take the amount of money you paid for your MP3 player- double it- would you still have bought it at that price? That IS what happens when you add in a 2 to 0 dollar component. Besides- the energy required for most items you cite- a solar panel makes it not portable. While you might be able to arbittrarily decide to go without an MP3 player for 24 hours, could you do it for a week? How about your cell phone? It uses more power- so go without it for 2 weeks. You still need batteries to be charged by solar panels due to one major flaw of solar panels- they do not work in the dark. So in effect all you are really doing is weighing the device down with a solar panel, and you still have not gotten away from a need for a battery. I don't know about you, but I have an MP3 player about the diameter of a 50 cent piece- where are you going to put the solar panel??? It will not have enough power to operate the device, and marginal at best for charginthe battery which would take hours instead of the minutes it takes connected to a USB port.
Q:Solar Panel Voltage Question?
yes, i suggest u connect in parallel
Q:Do I only need solar panels to have energy in day and through the night?
solar panels don't store energy, they only generate it. If you want to store energy you need a battery bank of some kind to get you through the night and anytime the sun isn't shining. If you have a little extra in the budget you might look at a geothermal system for your home's heating and cooling needs. They're highly efficient systems and you can supplement however you like. Whatever you do, though I hope you have a good building envelope in place already. Solar panels are cool, but if you have a leaky house, you're still not getting the best out of your panels. Do the more mundane stuff first. Insulation, windows, and weather-tight doors.
Q:What specification of solar panel do I need?
I okorder.com/ says they have DC to DC solutions from 2 V for most laptops.
Q:Computation of Solar panel requirement?
The power output of a solar panel uses a formula to determine kilowatts produced per hour per square meter per day. This calculation is important because, if you plan to install a solar power system for your home, you will want to know how many solar panels will be needed. To calculate solar power requirements correctly, you need to gather the data that is needed for the calculation. First you have to find the average amount of solar radiation available for your area. You can use a solar radiation chart. This can range from a 4 to a 7 depending on the area you live in. Write the number down on a piece of paper and indicate it with the letters RA. Next is determine the amount of electricity that you use daily. Add the kilowatt-hours used per month from your utility bill. Multiply this number by ,000 to get the watt hours in a month. Divide the total by 30 for the amount of electricity you use daily. Write this number down and indicate it with the letters DE. Determine the percentage of your home that you want to power with the solar power system. Write this number down and indicate it with the letter P. Determine the system inefficiency factor for the solar power system. You should be able to find this on the brochure for the system or from the manufacturer's web site. Write this number down and indicate it by the letter I. Determine the power or yield that is required for your home. Use the equation P = I x (DE x P) / RA to find the power requirements in kWh. Divide the number from Step 5 by the peak wattage for a single solar panel to determine the number of panels you will need for your home. Goodluck! :)
Q:2 Questions on Solar Panels?
Solar panels are available in a wide variety of power ratings.  Energy is the sum of power over time, so how much energy a panel produces depends on the intensity of the light hitting it and how long it's applied. I understand that current single-crystal silicon PV panels are warranted to produce ~85% of their rated output for 25 years.  Most will do better, and will produce useful output for perhaps 50 years or more.
