1) What can the solar panels on the artificial earth satellite be converted into and why? 2) What can solar water heater transform and why? 3) What can be converted into solar power station and why?

1) It is the conversion of light energy into kinetic energy, with internal energy loss in the middle
2) Conversion of light energy into internal energy
3) Conversion of light energy into electricity

Using solar cells to generate electricity under the sunlight is called photovoltaic power generation. Anyang City started the "photovoltaic project" demonstration project, and installed a photovoltaic power generation system with a total power of 20kW on the top of the teaching building of a middle school______ Can be converted into______ (2) how many kilowatt hours does the photovoltaic power generation system generate in a day when the effective illumination time of a day is calculated as 8h? (3) How many kilogrammes of coal does the photovoltaic power generation system need to burn if it is completed by a thermal power plant with 30% thermal power conversion efficiency? (calorific value of coal q = 3.0 × 107 J / kg & nbsp;) (4) please write a list of advantages of photovoltaic power generation

(1) When photovoltaic power generation system generates electricity, solar energy is converted into electric energy; (2) Power generation w = Pt = 20kw × 8h = 160kW · h; answer: the photovoltaic power generation system generates 160kW · h in a day; (3) 160kW · H = 160 × 3.6 × 106j = 5.76 × 108j; q = w η = 5.76 × 108j30% = 1.92 × 109J; the mass of coal burning M = QQ = 1.92 × 109j3 × 107j / kg = 64kg; answer: 64kg of coal needs to be burned. (4) the advantages of photovoltaic power generation: clean and pollution-free; renewable; saving fossil energy

How much energy does the motor consume per minute?
It's urgent!
The use of solar cars is one of the ways to develop new energy. There is a solar car. When the total power of the solar light on the car's panel is 8 * 10 cubic W, the voltage generated by the battery is 120V, and the current provided by the voltage to the car's motor is 10A
How much power is consumed by the motor per minute

(1)W=UIt=120V*10A*60S=7.2*10^4J
(2) Efficiency = w useful / W total = (120V * 10A - (10a) ^ 2 * 4eu) / 8 * 10 ^ 3W = 10%
(3) Advantages: energy saving and environmental protection
Disadvantages: low cost, high efficiency, limited by weather

What kind of solar panel can drive 1.5 HP household air conditioner
Where can I buy household solar panels?
How much does it cost? Is it a board or many pieces connected together?

It depends on how you use the air conditioner. Because you must use a battery when you use a solar cell, 2kW is enough. Now the price of the module is basically 30 yuan / W, so it needs about 100000 yuan
