I have already wrote about MC4 connectors, which will make the job of connecting several solar panels easily. When you are connecting panels in parallel you will also need T-branch connectors or Y connectors to make a two female connections or two male connections into one. Say good bye to ugly cable twisting and keep your connections clean, fit, and well connected . It will become easy when you disassemble the kit. Watch the attached video below to understand how it works.
