Introduction to Solar Energy Acronyms
Have you ever heard a solar energy term or acronym and wondered what it meant? Or maybe you’ve seen a chart or diagram full of acronyms and been unable to decipher the meaning behind them? If so, you’re in the right place.

This comprehensive guide to solar energy acronyms will provide an introduction to the world of solar energy acronyms, helping you to understand what they mean and how they are used.


An acronym is a word made from the initial letters of a phrase or name. This makes them a useful tool for communicating complex ideas in an efficient way. In the solar energy industry, acronyms are used for a variety of purposes, from describing the components of a solar panel system to measuring the efficiency of a solar cell.


There are many solar acronyms that are used in the field of solar energy, some of the most common ones include:

  • PV: Photovoltaic, refers to the technology used to convert sunlight into electricity using solar cells.

  • SPV: Solar photovoltaic, another term used to describe solar panels or systems that convert sunlight into electricity.

  • CSP: Concentrated Solar Power, refers to a technology that uses mirrors or lenses to focus a large area of sunlight onto a small area to produce high-temperature heat, which is then used to generate electricity.

  • TSI: Total Solar Irradiance, refers to the total amount of sunlight received at the Earth’s surface.

  • STC: Standard Test Conditions, refers to specific conditions under which the performance of a solar panel is measured, including a certain temperature, light intensity, and spectral distribution.

  • kWp: Kilowatt peak, a measure of the maximum electrical power that a solar panel or system can produce under specific conditions.

  • kWh: Kilowatt hour, a unit of energy equivalent to the energy consumed by a 1-kilowatt power source in one hour.

  • ITC: Investment Tax Credit, a tax credit offered to businesses or individuals who invest in solar energy systems.

  • FIT: Feed-in Tariff, a policy used by some governments to incentivize the adoption of renewable energy, where electricity producers are paid a guaranteed price for the electricity they generate.

  • BMS: Battery Management System, refers to the hardware and software components responsible for controlling and monitoring a battery system, ensuring its safe and efficient operation.

  • MPPT: Maximum Power Point Tracking, refers to the technology used to optimize the operating voltage and current of a photovoltaic (PV) system to ensure that it produces the maximum possible power.

  • DC: Direct Current, refers to the type of electricity produced by solar panels, which flows in one direction.

  • AC: Alternating Current, refers to the type of electricity used in most homes and businesses, which alternates direction periodically.

  • NES: Net Energy Metering, refers to a policy that allows homeowners with solar panels to send excess energy back to the grid and receive credits on their utility bill.

  • EPC: Engineering, Procurement, and Construction, refers to the three stages of a solar project, where the engineering design is completed, equipment is procured, and the construction of the project is carried out.

  • OEM: Original Equipment Manufacturer, refers to a company that produces components or systems that are then rebranded and sold by other companies.

  • OEMs are often involved in the production of solar panels, inverters, and other components used in solar energy systems.

  • LCOE: Levelized Cost of Energy, refers to a measure of the overall cost of generating electricity from a renewable energy source, including capital costs, operating and maintenance costs, and fuel costs.

These are just a few of the many acronyms used in the field of solar energy, and understanding their meaning can be helpful in navigating the industry.
