*Kilowatt Peak (kWp) is the unit used to measure the maximum power output a solar panel can produce under Standard Test Conditions (STC) in a laboratory, not actual production.
It's important to note that kWp represents theoretical peak output, not actual production. In real-world operation, the actual power generated can vary significantly due to numerous factors such as: Weather conditions (e.g., cloudy, rainy), Higher panel temperature, Panel orientation and tilt, Partial shading, Panel cleanliness, Time of day.

4 kW Home Solar Panel Installation Project in Sai Mai District, Bangkok
The PUMA SUNERGY team brings you an update on a solar power system installation project for the household sector in Bangkok. For this project, we were trusted to assess the structure and install a 4 kW solar panel system for a residence in the Sai Mai District area.
In an era of hot and humid weather, and with many families having a Work From Home lifestyle as well as elderly or small children staying at home during the day, turning on the air conditioner is inevitable. Installing solar panels on the home roof is therefore the most worthwhile and sustainable method to solve the problem of expensive electricity bills.
Make the Most of Every Square Meter with Safety from Microinverter
The challenge of installing solar panels for urban homes is "limited roof space." From the top view of the site, it can be seen that our engineering team has designed the layout to arrange the solar panels tightly together in a neat square to utilize the roof space for maximum efficiency in receiving sunlight.
Even more important than aesthetics is "the safety of family members." Therefore, we chose premium-grade equipment:
- 580W Solar Panels (8 Panels): Generates a total output of 4.64 kWp, which is enough to power 1-2 air conditioners and a refrigerator during the day.
- Inverter Model HM-1500 (2 Units): We chose Microinverter technology, which separates power conversion directly under the panels. This prevents high Direct Current (DC) voltage accumulation on the home's roof, eliminating the risk of electrical short circuits or fire, giving homeowners 100% peace of mind.
How much electricity cost can a 4 kW home solar panel installation save?
The 4 kW system is considered a highly worthwhile standard size for medium-sized residences. The system can generate an average of approximately 450 units (kWh) of electricity per month:
- Reduce monthly electricity costs: Saves approximately 2,250 THB.
- Reduce annual electricity costs: Saves around 27,000 THB.
With this level of electricity savings rate, the Payback Period will be approximately 4 - 4.5 years. After that, you will get to use electricity during the day for free for more than 20 years.
