*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 Residential 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 a household in Bangkok. For this project, we were trusted to design and install a 4 kW solar panel system for a residence in the Sai Mai area.
For families with a lifestyle of staying at home during the day, whether it's Work From Home or having elderly and small children who need to turn on the air conditioner to cool down, Installing solar panels on the home roof is considered the best helper in sustainably reducing monthly expenses.
Panel Arrangement Matching the Hip Roof with Safety Using Microinverter
A challenge with many housing estates is that the roof structure is often a Hip Roof, which has sloped areas in multiple directions and complex joints. From the top view, it can be seen that our engineering team has designed the arrangement of all 11 solar panels to beautifully and perfectly match the angles of the roof.
Due to the roof characteristics where panels might face different angles to receive light, choosing Microinverter technology is the most ideal solution. Because the system separates the operation of each panel independently; whichever side receives strong sunlight generates full power without dragging down the efficiency of panels on the other side. Furthermore, this system does not accumulate high Direct Current (DC) voltage on the roof, so you can be 100% confident that it is safe from fire risks.
How much electricity cost can a 4 kW home solar panel installation save?
The 4 kW system is a very popular size for medium-sized homes. It can generate an average of approximately 450 units (kWh) of electricity per month for home use:
- Reduce monthly electricity costs: Saves approximately 2,250 THB.
- Reduce annual electricity costs: Saves around 27,000 THB.
The Payback Period of this system will be approximately 4 - 4.5 years, which is considered a very worthwhile investment because after breaking even, you will get to use electricity during the day for free for over 20 years.
