Auringosähkön, also known as solar power or photovoltaics, is a method of generating electricity by converting sunlight into direct current (DC) electricity using photovoltaic (PV) cells. These cells are typically made from semiconducting materials such as silicon, which absorb photons from sunlight and release electrons, creating an electric current.

The basic components of a solar power system include photovoltaic panels, an inverter, and sometimes a battery storage system. Photovoltaic panels are composed of multiple PV cells, which are connected in series and parallel to form a module. These modules are then arranged in arrays to form a solar panel system.

Solar power systems can be categorized into two main types: grid-connected and off-grid. Grid-connected systems are connected to the electrical grid and can feed excess electricity back into the grid, often earning credits or payments from utility companies. Off-grid systems, on the other hand, are not connected to the grid and typically include a battery storage system to store excess energy for use during periods of low sunlight.

The efficiency of a solar power system depends on several factors, including the quality of the PV cells, the angle and orientation of the panels, and the amount of sunlight received. Advances in technology have led to improvements in the efficiency and cost-effectiveness of solar power systems, making them an increasingly viable option for both residential and commercial applications.

Solar power has several environmental benefits, including reduced greenhouse gas emissions, lower air pollution, and conservation of finite fossil fuel resources. Additionally, solar power systems can provide energy independence and resilience, particularly in remote or disaster-prone areas.

However, there are also challenges associated with solar power, such as intermittency, which can be addressed through the use of energy storage systems and grid integration. The initial cost of solar power systems can also be a barrier for some consumers, although the cost has been decreasing over time due to technological advancements and economies of scale.
