Question

what are the sources of solar energy ?How does proton-proton cycle generate energy?

Answer 1

Two positrons are released from this process, as well as two neutrinos (which changes two of the protons into neutrons), and energy.The core is the only part of the sun that produces an appreciable amount of heat through fusion. In fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius. By 30% of the radius, fusion has stopped almost entirely.

Answer 2

source of solar energy is only the sun and the proton proton cycle generate energy you can also find in Google
