The Types segment classifies residential panels by cell technology, influencing both performance and cost structures. Monocrystalline modules, characterized by high efficiency (18‑22 %) and superior temperature coefficients, command the largest market share, estimated at around 60 % of total units, due to their ability to generate more power per square metre on limited roof space. Polycrystalline panels, with efficiencies of 15‑18 % and lower material costs, occupy roughly 30 % of the market, appealing to price‑sensitive homeowners willing to accept larger array footprints. Thin‑film technologies, including amorphous silicon and CdTe, hold about 5 % of installations; they are favored in niche applications where flexibility or low weight is critical, despite lower efficiencies. Bifacial panels, a sub‑category of crystalline silicon that captures light on both faces, are emerging with an estimated 5 % share, driven by modest efficiency gains in reflective environments. Together, these type classifications delineate the market taxonomy that determines pricing dynamics, adoption rates, and overall market growth.
