n the original question, it says to only combine the parallel and series resistors, not the voltage or current sources. can you please complete it that way instead?
KVL and KCL
KVL stands for Kirchhoff voltage law. KVL states that the total voltage drops around the loop in any closed electric circuit is equal to the sum of total voltage drop in the same closed loop.
Sign Convention
Science and technology incorporate some ideas and techniques of their own to understand a system skilfully and easily. These techniques are called conventions. For example: Sign conventions of mirrors are used to understand the phenomenon of reflection and refraction in an easier way.

for this simplified circuit now,
calculate the mesh currents of the system at midday, when the solar panel delivers its rated current. Show all working. Calculate the voltage across and the power generated by the solar panel. Calculate the power delivered to the battery (including internal resistance), and the LED lights including their series resistors. What power is dissipated in the wiring? Check the power balances in your circuit.
