2026-02-04

Txawm hais tias ob qho tib si ua haujlwm rau lub zog hnub ci, lub zog hnub ci concentrated hom pej thuam (CSP) thiab photovoltaic (PV) fais fab tsim ua haujlwm ntawm cov ntsiab cai sib txawv kiag li, ua rau muaj qhov sib txawv tseem ceeb hauv lawv cov kev xav tau kev hloov pauv, cov lus qhia, thiab lub luag haujlwm ntawm lub kaw lus.

Hais yooj yim xwb: cov PV transformers yog "cov neeg koom tes nrog cov inverters," thaum cov tower-type CSP transformers yog "cov neeg koom tes nrog cov steam turbine generator sets."

Rau kev sib piv kom meej, qhov sib txawv tseem ceeb tau muab sau ua ke hauv lub rooj hauv qab no:
