How can you obtain the required amount of energy by connecting solar panels?

Explanation

(i) Solar cells contain the semiconductor Silicon
(ii) A Silicon solar cells of area 1 cm 2 , can generate 30 mA of electricity and 0.SV potential difference is obtained.
(iii) If two solar cells are connected in series the potential difference get added to 1V but electric current remains the same.
(iv) It two solar cells are connected in parallel , the current becomes 60 mA but potential difference remains the same. In this manner we can get the required potential difference and electric current.
