InsightBuyers guide: Powervault’s Jargon-buster


Entering the world of solar storage can sometimes feel like navigating a maze of technical terms and industry jargon. From inverters to kilowatt-hours, the terminology used in the solar storage market can be overwhelming for newcomers. However, understanding these terms is essential for making informed decisions about solar storage solutions. In this article, we’ll demystify some of the most common jargon in the solar storage market, empowering beginners to navigate the landscape with confidence.


  1. Solar PV System: A solar photovoltaic (PV) system consists of solar panels that convert sunlight into electricity. These systems are the foundation of solar energy generation and can be installed on rooftops or in open spaces.
  1. Inverter: An inverter is a device that converts the direct current (DC) electricity produced by solar panels into alternating current (AC) electricity that can be used to power household appliances and devices.
  1. Kilowatt-Hour (kWh): A kilowatt-hour is a unit of energy equivalent to one kilowatt (kW) of power consumed for one hour. It is used to measure electricity consumption and storage capacity.
  1. Battery Storage System: A battery storage system stores excess electricity generated by a solar PV system for later use. These systems typically consist of lithium-ion batteries housed in a storage unit.
  1. Depth of Discharge (DoD): Depth of discharge refers to the percentage of a battery’s total capacity that has been discharged. For example, a battery with a DoD of 80% has discharged 80% of its total capacity.
  1. Cycle Life: Cycle life refers to the number of charge-discharge cycles a battery can undergo before its capacity begins to degrade. It is an important factor to consider when evaluating the longevity of a battery storage system.
  1. Round-Trip Efficiency: Round-trip efficiency is a measure of the efficiency of a battery storage system in terms of energy input versus energy output. It indicates the percentage of energy that can be retrieved from the battery compared to the energy that was originally stored.
  1. Grid-Tied System: A grid-tied solar system is connected to the electricity grid, allowing surplus energy generated by the solar panels to be exported to the grid for credit or compensation. 


By familiarising yourself with the key terms and concepts in the solar storage market, you can confidently navigate the landscape and make informed decisions about your energy needs. Whether you’re considering installing a solar PV system, evaluating battery storage options, or exploring hybrid solar solutions, understanding the jargon of the solar storage market is the first step towards harnessing the power of solar energy for a sustainable future.
