Auto switch parallel-series connection

Hello all ! I have 4 supercapasitors connected in parallel to harvest energy from very weak power source ( indoor PV cell or similar ). As voltage across capacitors reach some level ( for example 0.2-0.3 volt ) I swap wires to connect supercapacitors in series to get 0.8-1.2 volts and unload energy to supercapasitor # 5.

As of now I do it simply by manual rewiring and planning to use dpdt toggle switches. Please advise circuit to automate this process. Thank you!
