The solar cycle is a natural cycle the Sun goes through as it transitions between low and high magnetic activity. Roughly every 11 years, at the height of the solar cycle, the Sun''s magnetic poles flip — on Earth, that''d be like the North and South poles swapping places every decade — and the Sun transitions from being calm to an active and stormy state.
Solar energy
About 125 GW of new solar PV capacity was added in 2020, the largest capacity addition of any renewable energy source. Solar PV is highly modular and ranges in size from small solar home kits and rooftop installations of 3-20 kW capacity, right up to systems with capacity in the hundreds of megawatts. It has democratised electricity production.
