You connect solar panels in series when you want to get a higher voltage. If you, however, need to get higher current, you should connect your panels in parallel.
Here we address some of the most frequently asked questions, myths and misconceptions surrounding solar energy, solar farms and solar panels. Do solar panels need bright sunshine in order to work? No. Solar panels don't need direct sunlight to harness energy from sun, they just require some level of daylight in order to generate electricity.
The solar panels are of voltage rating higher than the system voltage. You have two different higher voltage solar panels, i.e., one 100W/24V and one 200W/24V that you want to connect to the already working 12 V solar power system comprising the two 12V 50 W solar panels connected in parallel from the previous scenario (see the picture above).
