You can use two DC converters in cascade. The first DC converter is used to obtain MPPT, and the second one is used to obtain constant DC voltage by DC converter for varying irradiation and temperature in a solar PV system with a resistive load.

you can obtain constant voltage but if you want to maximize the output power you should adjust the load(R) to control the current .
this is done by another converter that has expense.
to obtain a constant voltage with varying irradiance and T, one should write
the pv equation and converter equation, then he or she relate the (I and T) to output voltage. this equation will have duty cycle of two convert(D1,D2).
by derivative of voltage respect to (I,T) and equal it to zero, one will have an equation that relate D1and D2 to (I,T).
