Benefits

Residential Scheme

Rexfield Green helps homeowners understand the right solar scheme before committing — from Solar ATAP to self-consumption options — ensuring every system is designed for compliance, efficiency, and long-term savings.

Solar ATAP helps homeowners offset electricity usage with solar energy while receiving export credit based on the Energy Charge Rate. Rexfield Green handles the design, SEDA and TNB submissions, and compliance process.

SELCO allows solar energy to be generated for own use, helping reduce dependency on the grid while maximising internal energy consumption through a simplified regulatory process.

What is Solar ATAP?

Old Incentive

NEM 3.0

New Incentive

Solar ATAP

Quota

›

Limited and ended

›

Starts on 1^st December

System Size

›

80%-90% of your TNB usage

›

Can be sized up to 100% of maximum demand, offering more flexibility for high-usage customers. (Subject to ATAP rules)

Program
Structure

›

Divided into three sub-programs (NEM Rakyat, NEM GoMen, NEM NOVA) with fixed quotas

›

A single, unified scheme for all TNB customers (domestic and commercial). Although still being finalized, it’s expected to be more flexible with no strict quota limits.

Offset/Export
Credit Rate

›

1-to-1 Retail Tariff Offset – Exported solar power is credited at the full retail electricity rate

›

System Marginal Price (SMP) Offset – Exported energy is credited at the wholesale SMP rate, which is at avg 20+ sen/kWh

Value
Proposition

›

Higher savings due to the 1-to-1 credit rate, resulting in a faster return on investment.

›

Focus on higher self-consumption – savings depend on how much solar power is used directly on-site.

Role of
Battery

›

Less important, since the grid effectively acted as a “virtual battery.”

›

Battery systems (BESS) become more valuable – allowing users to store excess solar energy for night-time or cloudy-day use, boosting savings.
