The Government of Thailand is planning to reserve 10,000 MW of rooftop solar capacity for households under the forthcoming Power Development Plan 2026 (PDP2026). Individual systems would be capped at around 5 kW, with surplus electricity purchased by the state and credited against household electricity bills. The government is also considering financial assistance and loan mechanisms to reduce installation costs.

The proposed scheme would simplify approvals through electricity distribution utilities and introduce online applications, while utilities would inspect installations before grid connection. PDP2026 is also expected to increase the share of clean energy in Thailand’s power mix from around 20 per cent to nearly 50 per cent within 10 years, with a longer-term target of at least 65 per cent.
