One major difference between solar and PV technology is that solar panels generate heat from the sun''s energy, but PV cells convert sunlight directly into electrical power. This means that while both technologies rely on the sun''s radiation as an energy source, PV offers a more efficient way to harness this power. However, it''s worth
