Q:Solar Panels question?
I would suggest getting more info about solar panels, here's the stuff that could be helpful to you renewableenergyarticles.blogspot....
Q:solar panels, wattage?
The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.

Q:Do homemade solar panels really work?
Home made solar panels should work just as well. You can make some thrifty ones that don't cost thousands of dollars! And it will truly save you a lot of money in the long run and can even power your home, even after a storm when everyone elses power is out
Q:Why are solar panels effected by operating temperature?
Absolutely temperature matters. So what do higher temperatures do to solar photovoltaic panels? As temperatures rise, the efficiency of solar panels decreases. Heat causes electrical resistance to the flow of electrons. On days where the temperature is more than 75 degrees, the electrical resistance makes the voltage fall thereby producing less kilowatts per hour. Your roof is much hotter than temperatures on the ground. That’s why solar panels are not mounted flat to a roof. There’s usually a few inches of spaces between the panels and roof so air flow can easily pass through and cool the panels down. There are some photovoltaic panels that are designed specifically to operate in hotter temperatures. These panels have a higher temperature coefficient. This is especially important in high heat climates like Arizona or New Mexico, but probably wouldn’t make too much of a difference in New England (except maybe this year). If someone lives in one of these areas, they should speak to a solar installer to make sure they are using they right equipment for their region. Please note: Solar thermal panels used to heat water can withstand high temperatures without any degradation. In fact, hotter temperatures would actually be better for these types of modules.
Q:Questions about the okorder.com solar panels?
Question# 5: Any state in the USA is entitle to a Federal Tax credit on their Income tax returns. Click on the source for details.
Q:Life expectancy of LEDs and Solar panels...?
LEDs last approximately 50,000 hours of operation, continuous or non-continuous, it doesn't matter. 50,000 hours. Solar panels will, theoretically, last until the end of time. The support structures will fail long before the panels themselves. Inverters, battery banks, op-amps, transformers, control boards, etc. will all fail long before a solar panel stops making juice.
Q:Where can i find a list of solar panel manufactures worldwide?
Actually Ofir, it is much easier and less expensive than you might believe. What you need is a magazine, like, Solar Today. There is only one that I am familiar with that gets into the nuts and bolts of solar panel manufacturers, installation, and other types of renewable energy. It's called, Home Power Magazine. We have a home that has been powered by the wind and sun for the last 0 years or so, and most of our initial information came from Home Power, and afterward, from many of the sources that they have in their articles. Every few issures, they take an item connected to renewable energy, such as an inverter, wind turbine, water turbine, or solar panel, and list all the different models that are available. They are broken down by manufacturer, and include specifications like power output, range of voltages, efficiency, materials, and even where they are manufactured. If you subscribe online for one year, the cost is around $25 USD, you will have access to all the previous issues that are archived on their website. You can use their search engine to locate an article listing all the solar panels, they did one a year or so ago with all the information you are looking for. Despite what you might be hearing, solar power usage is growing at an incredible rate. In the US alone, there are over 00,000 homes and businesses operating some level of solar power right now, that's good news. As far as different countries using different requirements, most all of the manufacturers today are selling their products to most countries worldwide, they are designed to meet requirements for almost anyplace you might use them. Check the magazine out today, you might learn more than you were originally looking for. I will include their link below, and some other good sources for information. You can google any one of them to find their website. Good luck, and take care...Rudydoo
Q:Joule Thief vs Solar Panel?
Solar panels convert light energy to electrical energy with an efficiency of around 5%. A SMALL solar panel will only produce a small amount of power (watts) your joule thief circuit wont help because as you draw more current from the solar panel the voltage will drop; and your joule thief circuit just reduces the efficiency of the whole system Try adding another solar cell in series to get more voltage and more power.
