When the rays of the sun strike the surface of photovoltaic panels, the sunlight is absorbed by the photovoltaic material inside solar panels. And the absorbed solar energy is converted into a type of electricity. In the case of solar thermal panels, we get thermal energy instead of electricity.
A solar energy system that covers this consumption pattern has an approximate value of 250k PHP for a 5kw solar energy system. Thus, your savings on the energy bill would be 2-4k, paying only the minimum rate, depending on your region. In 1 year of solar energy, you will have saved a lot. This results in a payback of 4 and a half years.
