9.2 MW Solar Expansion at Malaysian HVAC Plant

Panasonic Corporation Heating & Ventilation A/C Company has expanded its on-site solar generation capacity at Panasonic Appliances Air-Conditioning Malaysia Sdn. Bhd. (PAPAMY), increasing total installed capacity to 9.2 MW. The project supports the company’s strategy to establish net-zero factories and reduce operational CO₂ emissions in manufacturing.

Expansion of On-Site Solar Infrastructure
PAPAMY operates two production facilities in Malaysia: an air-conditioning factory manufacturing room air conditioners, commercial HVAC systems, and air-to-water heat pump systems (A2W), and a compressor factory producing air-conditioning compressors.

A 5.2 MW solar photovoltaic (PV) system was commissioned at the air-conditioning factory in November 2024. Since June 2025, additional PV installations have been implemented at the compressor factory. The newly installed system, with approximately 4.0 MW capacity, began supplying electricity on January 26, 2026.

With both installations operational, total on-site generation capacity at PAPAMY has reached 9.2 MW, representing the largest solar installation within the Panasonic Group.

Annual Generation and CO₂ Reduction
The combined systems are expected to generate 10,338 MWh of electricity annually. Based on internal calculations, this output corresponds to an estimated annual CO₂ emissions reduction of approximately 6,703 tons.

When operating at full capacity, the solar installations are projected to supply 18 % of the factory’s total electricity consumption. On-site generation reduces reliance on grid electricity and contributes to lower Scope 2 emissions, particularly in energy-intensive manufacturing processes such as compressor production and HVAC system assembly.

Integration into Net-Zero Manufacturing Strategy
The solar expansion aligns with Panasonic Group’s long-term environmental vision, Panasonic GREEN IMPACT, which targets virtually net-zero CO₂ emissions from its own operations by 2030.

For HVAC manufacturing operations, electricity consumption represents a significant portion of operational emissions due to testing lines, metal processing, motor assembly, and heat pump system validation. Increasing on-site renewable generation directly lowers the carbon intensity of these processes while providing greater energy cost predictability.

By combining photovoltaic capacity expansion with ongoing energy reduction and cost optimization measures in production processes, the HVAC Company is advancing its net-zero CO₂ roadmap within industrial manufacturing.

The PAPAMY installation demonstrates how large-scale rooftop or on-site solar systems can be integrated into high-volume HVAC production environments to reduce emissions while maintaining operational continuity.
