How many tonnes of concrete per megawatt do wind turbines use, and how many do nuclear power plants use? Solar plants used to use a lot of concrete, but they no longer do.
"Power factor" is an attribute of electrical loads, not electrical generating equipment; it describes how far the load's current consumption deviates from the perfect in-phase sine wave of, say, a resistor. Perhaps you meant "capacity factor", the ratio of average power produced to peak power produced. Typical capacity factors for wind turbines are in the vicinity of 35%, although some offshore wind farms reach 60%. Photovoltaic plants typically have a capacity factor of around 25%, though in sunny places like Arizona and California it can exceed 30%. In the US, the lowest PV capacity factors are in Maine, which averages 12%. Germany's average PV capacity factor is 10%. Natural gas peakers are around 9%.

I've already thoroughly demolished this nonsense about "need to be changed often" in the case of photovoltaic panels. I don't know what wind turbine lifetimes are. Shorter, I imagine, but they still have a much higher ERoEI than PV or in fact any other power source.
