They are just two different terms used to describe the same thing: a group of photovoltaic cells connected together to generate electricity from sunlight.

Dr Brian Johnston thank you for your contribution to discussion

Photovoltaic panels are installed for the conversion of thermal energy into electricity, while solar panels convert solar radiation into heat. This is why these solutions do not compete with each other. Instead, they may complement each other. At a smaller scale, domestic PV systems are more versatile than thermal systems, since they can power many appliances (solar thermal is limited to space and water heating). They also have a larger lifespan. Solar thermal is less effective in winter months when sunlight is not so strong, except for thermodynamic panels. Solar PV systems are more versatile than solar thermal ones. It can be very time consuming to find the right supplier.The pure efficiency at harvesting energy from the sun, solar thermal is more efficient at around 70% while PV is around 15-20%. Although your home may not benefit from direct sunlight during daytime hours, solar panels can operate with indirect sunlight so the benefits are abundant. Overall, solar panels are an excellent option for homeowners who wish to reduce their electricity bills and lower their carbon footprint at the same time. Galvanic cells consist of oxidation and reduction half reactions that are separated to find a current. Meanwhile photovoltaic cell relied on light to power a current through an anode and a cathode. A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity. Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy.A Voltaic or Galvanic cell is a type of electrochemical cell that converts chemical energy into electrical energy. Photovoltaic cells are used to convert light energy into electrical energy. An Electrolytic cell is a type of electrochemical cell that converts electrical energy into chemical energy.Photoconductive mode employs reverse biasing and provides higher sensitivity, wider bandwidth, and improved linearity. Photovoltaic mode employs zero bias and minimizes dark current. The next article in the Introduction to Photodiodes series covers several different photodiode semiconductor technologies.
