Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the core technology?Flexible thin-film photovoltaic array designed for rollable deployment
2. What is the primary use cases?Military operations, disaster relief, remote power, and temporary energy solutions
3. What is a Roll Out Solar Array (ROSA)?A ROSA is a flexible solar system that can be rolled up like a blanket and then unrolled to generate electricity. It uses thin‑film solar cells on a polymer film that can be compactly stored and quickly deployed.
4. How does a ROSA roll out and make power?The solar cells are wound around a spool. When the unit is activated, a motor or other mechanism unrolls the film, exposing the cells to sunlight so they can produce power.

Thin-film photovoltaic cells: Solar cells manufactured by depositing thin layers of photovoltaic material onto a substrate, offering flexibility and lower production costs.
Photovoltaic effect: The phenomenon where light energy striking a semiconductor material generates an electric current.
Scalability: The ability of a system or process to be expanded or reduced in size or capacity to meet changing demands.
Greenhouse gas emissions: Gases released into the atmosphere that trap heat, contributing to climate change.
