Why Solar Energy is Gaining Momentum in Tonga

With over 2,800 hours of annual sunshine, Tonga's tropical climate makes solar power a game-changer. Rising diesel costs and frequent power outages have pushed households and businesses to adopt solar solutions. In 2023, the Tongan government pledged to achieve 70% renewable energy by 2025 – and solar sits at the heart of this plan.

Key Drivers for Solar Adoption:

• Electricity tariffs increased by 15% since 2022
• 40% of outer island communities lack reliable grid access
• Global solar panel prices dropped 30% in the last decade
