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.
Q:Can you make a solar panel shift sideways?
having solar panels move like that on a mobile platform is inadvisable -- especially if there is a dynamic wind load resulting from the motion of the mobile platform. Even having a tilt mechanism is dubious at best. think of what limited marginal gain would be gained by mounting a small solar panel on the moon roof of a car. (ultimately, the best answer is to turn the car so that it's angle to the sun is optimal -- but the road/travel direction constraints are what ultimately prohibit that.) while there are ways to build sliding panels, the weight constraints would interfere with your weight/thrust ratios to the point of futility. if you really need that panel somewhere else, don't slide it out of the way, just buy another panel and mount it there. it's more expensive, but it's actually the cheapest solution in terms of design on a mobile platform.
Q:how to make a solar panel?
In another building, workers weld solar cells together into strips, then align them by eye on a light box to form the rows and columns of cells that make up a complete solar panel.
Q:what do we mean by efficiency of a solar panel?
Photo-voltaic solar cells use the visible light range (photons) for the conversion of sun's rays to electrical energy. The potential of solar radiation is ,353 Watts per square meter, but that is mostly a measure of heat, or infrared radiation. The visible light is actually a small portion of the spectrum. You have struck on a problem associated with photo-voltaic cells. Infrared radiation acts to heat up p-v cells (heat stress), causing them to be much less efficient. It would be interesting to see a hybrid p-v panel that is cooled with fluid or air running through it. This would increase efficiency of the p-v process while providing a heating source. This in turn could be used directly for heating or for production of electricity through a generator system.
Q:What makes solar panels Inneficient?
Solar panels produce very little heat or sound compared to electrical energy. In terms of the sunlight striking the panels, solar panels have an extremely poor efficiency because they can't possibly absorb 00% of the light energy. Solar panel efficiency is usually given is terms of converting the light that IS absorbed into electricity. Improvements are happening constantly. Mainly, trying to maximize electrical conductivity.
Q:Solar Panel Voltage Question?
yes, i suggest u connect in parallel
Q:why aren't solar panels for your house more affordable?
Technology okorder.com Good luck!
Q:Solar Panels Energy Theory?? ENERGY?
No. okorder.com/... Since then they have only improved. CdTe efficiencies have increased, partly by reducing material use (particularly the depth of the CdS layer)
Q:Do it yourself Solar Panels?
sure, but if you don't know what you are doing you could really hurt or kill yourself. Basically you can do whatever you want on your side of the power meter and in the rare occurrence when your solar panels are producing more power that your home is using the meter will run backwards and you will be feeding power to the grid and theoretically reducing your power bill. At the very least you will be using less power from the grid
Q:how much would it cost to generate MW electricity by solar panels??? and how much land it requires ?
I like Rouse's answer, which points to the factors to consider. If you are in India, adjust the inputs to match your local situation. For example, the peak equivalent sun-hours per day might be twice his figure, leading to half the cost. You might find panels that have a 25-year life, reducing the cost per kWh by another 20%. Land and/or labor may be cheaper, also reducing the cost.
