SOLAR ENERGY SYSTEM CALCULATIONS
1. SOLAR PANEL TYPE
BC 670W Half-cut Monocrystalline PV Modules Aiko Solar brand (Tier 1 Solar PV Panel, China)
2. SOLAR SYSTEM CAPACITY
Power per pc: 670W
No. of panels: 12
System capacity = 12 x 670 /1000 = 8.04 kWp
3. ESTIMATED MONTHLY ELECTRICITY GENERATION FROM SOLAR
Assume: Sun hours per day/year: 3.30 hrs.
Monthly electricity generated = 8.04 x 3.30 x 30 days = 796 kWh
4. POTENTIAL SAVINGS ON ELECTRICITY COST PER MONTH
Assumption: 30% solar generation for self-consumption during daytime and 70% export to TNB Grid
Rate for savings in daytime: RM 0.4443/kWh
Rate from export (energy charge): RM 0.2703/kWh
Solar usage consumed in daytime = 30% x 796 = 239 kWh
Balance solar export to TNB = 70% x 796 = 557 kWh
Saving in daytime = RM 0.4443 x 239 = RM 106
Saving from export = RM 0.2703 x 557 = RM 150
SST (daytime saving) = 8% x RM 106 = RM 8
KWTBB (daytime) = 1.60% x RM 106 = RM 2
-----------
Total saving per month RM 266
5. RETURN OF INVESTMENT (ROI)
Solar system investment: RM 19,000
Simple payback period = 19000 / 266 / 12 months = 5.95 years

MY ROOFTOP SOLAR PHOTOVOLTAIC (PV) INSTALLATION
Four (4) Registered PV Service Providers (RPVSP) were approached, viz. Brilliant Solar, Green Innotech, Pathgreen Energy and Eco Hybrid Solar. Three of them came for site inspection using a drone to check the roof and advise on the required quantity of panels based on the existing single-phase power. The other service provider came without using drone.
It is decided that a system of 12 pieces of solar panels and 3 nos. of micro-inverters is to be used and the prices varied from RM19,000 to RM24,000.
I have resorted to DeepSeek and ChatGPT to provide evaluations and recommendations on all 4 proposals received, considering financial value, technical & brand strength, programme choice, provider's credibility & experience and etc. Both AI models impressed me very much for their instantaneous responses with very detailed and comprehensive feedback.
I finally decided to select Pathgreen Energy for submitting the most competitive quotation in view of the following factors:
1. Lowest price per kWp / Best price-to-size ratio
2. Strong after-sales support including:
(a) 5-year free O&M / monitoring / annual maintenance
(b) 5-year workmanship warranty
3. Premium hardware stack
4. Commercial-grade installer discipline
5. Good ROI / payback estimate
Pathgreen Energy’s package comprises 12 pc. AIKO 670Wp and 3 no. Hoymiles micro-inverters 8.04 kWp for a total amount of RM19,000.
ChatGPT also provided a technical audit by stating that AIKO 670W is viewed as premium/high-efficiency (Tier-1, 30-year performance), and Hoymiles micro-inverter has good smart monitoring ecosystem and strong growth / adoption in Malaysia.

Half-day Visit to Kuala Pilah, N.S. on May 27, 2026
They came to BSL to fetch Soh Ai and I at 2.40pm and used LEKAS Highway to go south. We reached Tokong Si Thian Kong at 3.50pm for the first-time ever visit for all of us.
This temple was built on 4.8 hectares of land, dedicated to various deities and showcases beautiful traditional architecture adorned with intricate carvings and vibrant colors. Surrounded by lush greenery, it serves as a peaceful retreat for worshippers and visitors alike.
The site is also known for its spiritual significance and cultural heritage, making it an interesting destination for those keen to learn about local customs and practices. It is a place to worship the Nine Emperor Gods (九皇大帝) and other Taoist deities.
One attraction is the Shouting Fountain (喊泉) which is an interactive voice-activated fountain. The louder and longer one shouts through a wired pipe, the higher the water fountain goes.
We left the temple at 5.45pm to look for a restaurant for dinner. I used my mobile phone to Google-search a seafood restaurant in Tmn Desa Melang, Kuala Pilah. Unfortunately it was closed when we reached there.
After driving around town for a while, we discovered most if not all of the shops were closed. We finally found a one-man eatery on the ground floor of a clan association building Moon Kee Bak Kut Teh (滿记肉骨茶)near Bazar Melayu Pasar Rabu at about 6.30pm.
We savored yellow wine chicken (黄酒鸡 RM50), black vinegar pork trotter (猪脚醋 RM20), dry Bak Kut Teh (干肉骨茶 RM22), claypot Bak Kut Teh (瓦煲肉骨茶 RM20) and boiled choy sum (油菜心 RM10). The total cost including 5 bowls of rice amounted to RM132, paid by me in appreciation of fellowship.
Saw sent Soh Ai and I back home at 9.00pm, concluding a pleasant half-day trip to Kuala Pilah.
