Thin-Film Solar Cells: Definition, Types & Costs
Thin film solar cells typically cost $0.50 to $1 per watt on average, but they typically have a shorter lifespan of 10-20 years compared to other types of solar panels.
Thin-film solar panels offer a lightweight, flexible alternative to traditional solar options, making them a smart choice for large roofs, commercial spaces, and unconventional surfaces. These panels typically cost around $0.75 per watt, with total system prices for an average home ranging from $9,000 to $15,000, depending on installation needs.
As solar energy adoption accelerates in 2025, a new generation of panels is gaining momentum: thin film solar panels. Known for their flexibility, low weight, and minimal material usage, these panels are increasingly finding their place in commercial and industrial settings.
Thin film technology comes in several variants, each designed for specific needs, from handheld gadgets to utility-scale solar farms. Below is a detailed look at the most popular types used in 2025: This is the oldest and most basic type of thin film solar cell.
Amorphous silicon solar cells cost between $0.50 to $1.50 per watt, while CIGS is in a range of $0.60 – $0.70. GaAs are more costly, with their price being around $50 per watt. The cost of a portable thin-film station, which is a common application of thin-film solar technology, ranges from under $1,000 to around $5,000.
