## 4. Government Incentives & Regulations in Thailand

- **Personal Income Tax Deduction (Up to 200,000 THB)**: Thai tax residents who install residential solar rooftops with VAT-registered certified contractors and obtain legal grid-connection permits are eligible for personal income tax deduction up to 200,000 THB.
- **Government Solar Support Budget (50,000 THB - Solar for 1 Million Households)**: Official 50,000 THB subsidy per household from the 50,000M THB national energy transition decree (1,000,000 households target). Cabinet approval on 26 Oct 2026; official registration opens early November 2026 via MEA and PEA. Average installation cost ~140,000 THB, net customer payment **90,000 THB**. Financed by 3 state banks (GSB, GHB, BAAC) at 2.5% special interest for 7 years (zero upfront cash needed, repaid via solar savings and 2.20 THB/kWh feed-in tariff). Over 1,000 certified contractors participating. 1 meter = 1 right; subsidy disbursed after utility grid connection. Details: https://evpowerenergy.com/solar-rooftop-50000

## 5. Frequently Asked Questions (FAQ)

### Q: Does an On-Grid solar system work during a power outage?
**A**: No. Standard On-Grid solar inverters shut down immediately during grid outages (anti-islanding safety feature) to prevent hazardous power back-feeding into the utility grid while technicians are conducting repairs. To maintain uninterrupted power during blackouts, customers must install a **Hybrid Solar System with a Battery Energy Storage System (BESS)** such as the Huawei LUNA2000 or Sigenergy SigenStor.

### Q: Which roof types in Thailand are suitable for solar panel installation?
**A**: Solar panels can be installed on almost all standard roofs, including CPAC concrete tiles, flat concrete slab rooftops, and metal sheet roofs (both screw-fixed and seamless Klip-Lok standing seam clamps with no drilling required). Old corrugated fiber-cement tiles older than 10-15 years or rusted zinc roofs require structural inspection or replacement before installation.

### Q: What is the optimal roof orientation and tilt angle for solar in Thailand?
**A**: Due to Thailand's geographic location slightly north of the equator (latitudes ~6°N to 20°N), the ideal orientation is **facing true South** with an inclination tilt angle of **10° to 15°**. East and West facing roofs are viable secondary orientations, yielding ~85-90% of south-facing output.

### Q: Do I need a second electrical meter (TOU) to install an EV Charger at home?
**A**: If your existing electrical service has sufficient capacity (e.g. 30(100)A Single Phase or 15(45)A Three Phase), a separate meter is optional. However, applying for a dedicated **2nd TOU (Time of Use) meter** from MEA or PEA is highly recommended because it offers substantially discounted off-peak electricity rates on weekday nights and all day during weekends/holidays, reducing EV charging costs to approximately 2.60–2.80 THB/unit.
