AUTOMATIC DROOP CONTROL FOR A LOW VOLTAGE DC

What is the voltage of photovoltaic series inverter
A solar inverter or photovoltaic (PV) inverter is a type of which converts the variable (DC) output of a into a (AC) that can be fed into a commercial electrical or used by a local, electrical network. It is a critical (BOS)–component in a , allowing the use of ordinar. Input voltage (Vcc): this value must be equal to that of the battery (12, 24, 48 V). Output voltage (Vac): this value must be normalized (230 Vac). [pdf]
Will connecting photovoltaic panels in parallel increase voltage
When connecting solar panels together in parallel, the total voltage output remains the same as it would for a single panel, but the output current becomes the sum of the amperage of each panel. [pdf][FAQS about Will connecting photovoltaic panels in parallel increase voltage ]

Solar power generation method DC
Solar panels generate electricity through the photovoltaic effect. When sunlight hits the solar cells within the panel, it excites electrons, causing them to move and create an electric current. [pdf]
