Answer:
the answer is mabye 30 I didnt understand
"The Solar electricity source of energy comes from the sun’s rays. It is more often in the form of a panel known as the solar panel. It has a photovoltaic system that generates and supplies energy in commercial and residential areas. Even though numerous countries are using this type of electricity to save electric-induced power, it is not used for a number of reasons. One is that 1 panel with a size of 6 by 10 solar cells is expensive. There are countries who cannot afford to buy them. Two, it requires a larger area to place the panel. Three, the efficiency is low. The smaller the panel is, the lower its efficiency and therefore produces lesser power to generate a specific area."
Observation, hypothesis, experiment is the correct answer
