How Much Can a 6 kW Home Solar Cell Installation Save on Electricity Bills?
The 6 kW system for this project can generate an average of approximately 800 units (kWh) of electricity per month for home usage, clearly helping reduce family expenses:
- Reduce monthly electricity costs: Saves approximately 4,000 THB
- Reduce annual electricity costs: Saves around 48,000 THB
The payback period for this system will be approximately 3.5 - 4 years, which is considered a highly worthwhile investment. Because after reaching the break-even point, you will get to use electricity during the daytime for free for over 20 years according to the solar panels' lifespan.
