Q:Solar Panel Help? Beginners?
The okorder.com/... All the other sites you google/yahoo for will be advertisements. I think the author of this one was a engineering student. Hope this helps!
Q:How effective are solar panels?
Well, the maximum amount of energy you can receive with 00 percent efficiency is kilowatt per square meter. This is the energy that hits the Earth's surface. The best commercially available panels are 20-30 percent efficient. Cutting edge technology has gotten this percentage up to 50 percent, but you can't buy these for your home. If you're curious about efficiency, check out a panel's dimensions, find the area in square meters, and use that along with its Watts (divide by 000 to get kilowatts) to get your answer.
Q:What does solar panel power?
I doubt it'd supply your heat. Anything involving electric heating uses tons of energy. Also, keep in mind that you don't just need a panel but also a DC to AC converter.
Q:How to connect solar panels to batteries?
20 volts is a common open-circuit voltage for nominal 2v panels. The panels put out about 5v at full load. If the panel puts out little enough that it takes 20 hours or more to put a full charge in the battery you can get by without a charge controller - just keep the cells topped up with distilled water. A charge controller will do a more efficient job, though. The most efficient charge controllers use what's called Maximum Power Point Technology (MPPT) which lets the panels operate at their most efficient point throughout the battery's charging cycle. Available on OKorder. The charge controller should have the same or higher wattage as the panels it controls - if you're not sure of wattage, assume that they are the same as similar area panels you find for sale. Before buying a charge controller, connect the panels through an ammeter to a discharged battery. They may have been trashed because of damage and low output. You need at least an amp for trickle charge, 5 amps for reasonable recharge times.
Q:How much does 000 square feet of solar panels cost?
Are you asking about solar water heaters or solar electric panels?
Q:How Solar Panel Works ?
when sunlight hits a solar panel the photons from the light hit a layer in panel that converts it into electrons through conduction, thus making electricity
Q:Has anyone had roof problems caused by rooftop solar panels?
Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.
Q:2V Solar panel directly to 2V inverter...and restult.?
There okorder.com/ 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:South facing solar panels?
You want the panels facing south because that is where they would get the most sunlight throughout the day. If your front door is facing north, then the back of your house would be facing south, right? So put them up in the back where they are facing south...haha wtf..
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! :)
