Q:how much solar panel power do i need?
My guess is that you might discover everything concerning solar power at www.okorder.com.
Q:what do we mean by efficiency of a solar panel?
That portion of the sun's light to which it responds, of which it converts 20% to electricity.
Q:How much energy does it take to make, install, and eventually dispose of a solar panel?
At present the technology to create silicon solar cells is incredibly energy intensive. It is not logical to compare the cost of oil to the cost of a solar cell because they are not priced according to energy input. Oil has a strong advantage in that it is concentrated solar and geothermal chemical energy that has accumulated over millions of years. The price of oil does not reflect its energy content, but the cost to retreive it. Electrical energy used to produce a Photovoltaic cell is not priced in any proportion to oil. By some calculations it will take about 50,000 KWh of energy produced by the PV cell before it can recover the energy used to manufacture it.
Q:Solar Panels and a Car Headlight?
it should power 2 55/60W 2V headlights, at full output. But it may be less, depending on the brightness of the sun, and the length and type of wire used.
Q:Why are solar panels still so expensive?
materials and process... if they could be built in a sweatshops, by kids, in Malaysia, they'd be cheap and everyone would use them
Q:Solar Panel Circuit Question?
I suspect the voltage is OK but the amount of current the solar cell is capable of delivering is less than the relay coil needs to operate. The current the relay tries to draw overloads the PV. You need to add additional PVs in parallel to operated the relay coil. An alternative is to use a low current draw relay coil or use a transistor switch. Hope this helps, NewtonLaw
Q:where could i buy a cheap and low cost solar panel regulator?
investigate Tractor grant... they have been given small, medium and massive. Wal-mart additionally has infants for image voltaic lights... you ought to string them very close jointly to get volts up... i offered an merchandise which you defined as what you will make -- inexpensive fan with a image voltaic panel on it from Wal-mart--- it cools the interior my vehicle on sunny days.
Q:solar panels......................................................................?
hardware store
Q:how does solar panels give power to the batteries?
solar panel convert sunlight into electricity,The controller is connected between the photovoltaic panels and batteries,it makes electricity generated from solar panels charge batteries.
Q:Cars with Solar Panels?
There are lots of cars with solar panels, but they are all experimental. The problem is that the power required to run a car is a lot more than the limited number of solar panels can produce. The sail boat can use the solar panels as sails, to get power from both.
