Consider the following statements regarding a purely grid-connected PV system design: a) The grid-connected system does not necessarily need a battery storage, because the grid can uptake and feed power when needed. b) The PV system should be designed such that the PV array continues to feed the grid, even in the event of a grid network failure. c) The grid-connected PV system can only be designed around the required load that needs to be powered. d) The PV array configuration should ensure that the DC current and voltage limits at the input of the inverter are respected.Which of the above statements is/are NOT true?

A. a) and b) only
B. b) and c) only
C. All of a), b), c) and d)
D. c) and d) only

The \(V_{mp}\) and \(J_{mp}\) of a non-ideal solar cell are given in the plot above. The area of the solar cell is \(4 cm^2\). Having in mind the equivalent circuit of the non-ideal solar cell, calculate the current in \(mA\) at the shunt branch if \(R_{sh}=0.04 \Omegam^2\) and \(R_s=2.810^{-4} \Omega*m^2\) when the solar cell is operating at the maximum power point.According to your answer above, calculate how much power in \(mW\) is dissipated due to shunting of the solar cell at the maximum power point. Hint: Remember two things: (1) the relation between power, current and voltage and (2) Ohm's law! ______
