Tiếng ViệtOPERATION & MAINTENANCE
FOR SOLAR POWER SYSTEMS
Why do you need professional O&M service?
Solar power systems after 3-5 years of operation typically lose 15-25% efficiency due to dust, oxidation, loose connections or component failure. Regular O&M service helps maintain stable power output and extend equipment lifespan to 25+ years.
