PV systems are most commonly in the grid-connected configuration because it is easier to design and typically less expensive compared to off-grid PV systems, which rely on batteries. Grid-connected PV systems allow homeowners to consume less power from the grid and supply unused or excess power back to the.

Solar energy will convert into electricity. Through a process known as photovoltaic (PV) conversion. In this process, solar panels made of silicon or other semi-conductive materials. Absorb the sun''s energy (sunlight) and convert it into electricity. The absorbed sunlight causes electrons in the material to become excited.
PV cells are electrically connected in a packaged, weather-tight PV panel (sometimes called a module). PV panels vary in size and in the amount of electricity they can produce. Electricity-generating capacity for PV panels increases with the number of cells in the panel or in the surface area of the panel.

Let''s begin with an overview of the sun as a power source before examining the two main mechanisms used to convert sunlight into electrical current. Solar power on Earth begins about 93 million miles away.
Solar energy - Electricity Generation: Solar radiation may be converted directly into solar power (electricity) by solar cells, or photovoltaic cells. In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.
Conversely, extremely cold temperatures can increase power generation above the nameplate rating as the PV cell voltage increases at lower temperatures below STC (25°C). Solar panels can exceed the panel power rating (Pmax) for short periods of time during very cold weather. This often occurs when full sunlight breaks through after a period of
