Electrical current that reverses its direction of flow in a regular pattern, typically used in households and businesses.

A billing mechanism that credits solar energy system owners for the electricity they produce and add to the grid.

A measure of solar radiation energy received on a given surface area in a given time, typically expressed in kW·h/m² per day.

The radiant energy emitted by the sun, which can be harnessed and converted into electricity or thermal energy.

A technology for harnessing solar energy for thermal energy (heat).

A technology which uses mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a small area to generate heat that can be used to produce electricity.

The characteristic of solar energy that makes it an inconsistent power source due to the variability of sunlight availability.

A situation where an alternative energy can generate power at a cost and performance level equal to or less than electricity generated from conventional methods.

A type of electrical current that flows in one direction only, often used in photovoltaic systems before conversion to alternating current (AC).

The amount of time it takes for a solar energy system to produce energy equivalent to the energy used to produce it, also considering financial payback through savings on energy bills.

A method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect.

A collection of solar cells that can convert light directly into electricity.

A device that converts the variable direct current output of a photovoltaic solar panel into a utility frequency alternating current that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.

An electrical device that converts the energy of light directly into electricity by the photovoltaic effect.

A measure of the ability of a solar cell or module to convert sunlight into electricity, expressed as a percentage.

A solar cell that is made by depositing one or more thin layers of photovoltaic material on a substrate, offering a simple production process but generally lower efficiencies.

A design approach that utilizes the natural movement of heat and air to maintain comfortable temperatures in living spaces, reducing or eliminating the need for mechanical cooling or heating.

A type of solar cell made from multiple crystal structures, a more cost-effective option compared to monocrystalline but with slightly lower efficiency.

A type of solar cell made from a single crystal structure, known for high efficiency and long lifespan.
