Definition:
A solar battery is a type of electrical device that stores energy from the sun. It is made up of many small solar cells that work together to capture sunlight and convert it into electricity. This electricity can be used at a later time, even when the sun is not shining.
In more technical contexts, you might discuss the efficiency of solar batteries, their capacity (how much energy they can store), or the technology behind the solar cells.
In general, "solar" refers to anything related to the sun. While a "solar battery" specifically relates to energy storage, the term "solar" can also be used in other contexts, such as "solar energy" (energy from the sun) or "solar power" (the power generated from solar energy).
While there are no specific idioms or phrasal verbs directly related to "solar battery," you might come across phrases related to energy or sunlight, such as: - "Run on fumes" - This means to be almost out of energy or resources, similar to a solar battery running low on stored energy. - "Burn the midnight oil" - To stay up late working, similar to using stored energy at night when the sun is not shining.
A solar battery is an essential part of using solar energy effectively, allowing us to store the sun's power and use it when we need it.
