How many watts does solar make?
Solar panels can make enough watts to power your whole house if you have enough of them. Some solar panels will generate 50 watts, 80 watts or 120 watts.
12 volt solar equal to amp?
Solar panels are rated in watts output. To find the amperage use this equation, Amps = Watts/Volts. The wattage will be on the nameplate of the solar panel.
How many watts do you get from a square meter of solar panels?
The amount of power you get depends on a number of factors, including the efficiency of the solar panels. Ideally, the energy of sunlight would be about 1366 watts per square meter, but losses do to such things as the atmosphere reduce this to a practical limit of about 1000 watts. If a solar panel of one meter is 10% efficient, then this means you would get about 100 watts. New technologies are achieving efficiencies approaching 50%, which would produce 500 watts; but some older panels were only 6% efficient. Since you ask about watts, I am assuming you mean photovoltaic panels. Solar thermal collectors are more efficient, but do not produce electricity.
How many solar panels will be required for a solar system - four rooms - 3 solar fans - fridge - lighting - cooker - heater - mobile charger - tv and other uses?
To calculate the power used it is necessary to add up the power requirement: typical power values would be solar fans 0, fridge 20 watts average, lighting 200 watts, cooker up to 3000 watts, heater up to 3000 watts, mobile charger 3 watts, TV 150 watts. Solar panels of around 1.2 metres by 1 metre produce about 220 watts in maximum conditions, or about 15 watts out of direct sunlight. So without the heater or cooker a couple of panels should do it on a sunny day, otherwise add 15 panels for the cooker OR the heater.
How much would it cost to replace Fukushima with solar panels?
Fukushima Generates around 13,000 Mega watts of electricity. You need 434 Solar Panels for 1 Mega Watts. Calculation 434 Multiplied by 13,000 Equals to 5,642,000 Solar Panels. Cost of 1 solar panel 3,500 $ So 3,500 Multiplied by 5,642,000 = 14,747,000,000 USD. A single Nuclear Powerplant costs 400 Million USD.
How many watts of solar panels requires to run 15 hp electric motor?
36 No's of 300w solar modules required
How many watts are required to start a 7 HP 12 VDC motor you want to start the motor on solar panel?
For calculation purposes 1 HP is equal to 746 watts. So you have a total of 746 x 7 = 5222 watts. The amperage will be A = W/V = 7222/12 = 435 amps. You can not start the motor directly off of the solar panel. You would need a large 12 VDC parallel connected battery bank to obtain the amperage capacity to start the motor. The solar panels would be connected to the battery bank and used to charge the batteries after the start.
How do I know how many watts I need when buying solar panels?
It's just like any other budget. You start by figuring out how many watts you use.
How many solar panel can generate 1 mega watt?
it depends on your solar panels, i can tell you if you know the amperage and the volts, you can find the amount of watts it produce, the equation is watts = amps x volts. hate to give you an equation as an answer
How many Solar panels required for 1400 volt amp inverter?
8 x 170 watt panels = 1360 Watts total. The actual output would depend on your location in the world. Other factors include aspect and pitch of the solar panels, wiring losses and temperature coefficients.
How much land would need to be covered in solar panels to replace one nuclear power plant?
A typical Nuclear Plant with 4 units active generated 13,000 Megawatts of Electricity. A single Solar Panel Generates Just 200 Watts while its sunny. 1 mega watt is 1 million watts. 13,000 Mega watts is 13,000,000,000 Watts. So we divide 13,000,000,000 Watts by 200. we need 65,000,000 Solar Panels. 1 Solar panel covers approximately 4 by 4 Meters. So the area is 16 metre^2. 65,000,000 Multiplied by 16. 1,040,000 Kilometres of land.
Can you charge a battery with solar panel producing 245 watts?
You can't charge the battery with those 245 watts unless they are being 'pumped into' the battery at a higher voltage than the battery puts out. If you can exceed the voltage of the battery, that 245 watts will definitely charge a battery.
