This is not a point against solar, but the "lifetime" of wind turbine installations is misrepresented in the article. It states "the life expectancy of a wind turbine may be less than 15 years." and it links one 7 year old article to support that idea, which is known to be false except in the sly sense that for sure a windturbine may need repairs at any time.
Modern windfarms are commonly financed to be built and make a profit from investment by selling electricity for 15 years. After that contract is up, however much they require new blades and/or refurbished or modernized generators - extending their life is due to be much cheaper than putting entirely new ones in their foundations. The relatively short supply contracts are very desirable to investors, not a sign of unreliability.[1]
