Solar panel
Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.

AC-coupled vs. DC-coupled solar | SolarEdge
Since solar panels produce DC, and batteries store DC energy, it makes sense that the battery storage system also works on DC electricity. In an AC-coupled system, the energy generated from the solar panels is converted to AC, converted again to DC to store in the battery, and when in use in the home, converted back to AC.
Solar inverter sizing: Choose the right size inverter
A solar power inverter typically lasts 10-15 years, so you''ll probably have to replace it some time during the life of a solar system. What is a good DC-to-AC ratio? A 1:0.8 ratio (or 1.25 ratio) is the sweet spot for minimizing potential losses and improving efficiency.
