By design, wind power’s system and favorable wind sites usually do not favor solar energy, with few exceptions. Favorable wind resources are more often associated with mountainous systems or within close proximity to them, as opposed to favorable solar resources, which are common in large plains with poor winds. Technology-wise, they are absolutely compatible as they compensate each other’s intermittency. Solar is among the most stable renewable energy sources in terms of predictability and with new technological developments, the certainty degree is increasingly higher. Wind power systems, to date, do not provide this degree of power output certainty but they can start producing power as early as 4am, compensating solar power’s limitation of producing power at late hours..
