What specific type of early solar application was experimented with around the 1890s?

Answer

Solar-powered street lighting

Records from the late 1800s indicate that rudimentary forms of solar-powered lighting were explored, specifically mentioning early implementations of solar-powered street lighting around the 1890s. These initial endeavors utilized the core components of photovoltaic cells and basic battery storage, although they were established as fixed, large-scale installations, significantly different from the personal, portable devices developed much later.
