🧾 Comparing Electricity Bills: With Solar vs Without Solar (Real Case Study)

Published 2025-08-31

β€œIs the savings really that big after installing solar?”

βœ… Let’s look at a real example from a Malaysian homeowner β€” before and after going solar β€” so you can see the numbers for yourself.


πŸ“Š Case Study: Family in Selangor

Before Solar Installation:

  • Monthly TNB Bill: RM620–RM700
  • Household: 2-storey terrace, 2 airconds, water heater, WFH usage
  • Usage: ~1,400–1,600 kWh/month

After Solar (6.82kWp, NEM 3.0):

  • Monthly TNB Bill: RM20–RM80
  • Solar Generated: ~750–800 kWh/month
  • Monthly Savings: ~RM550+
  • Payback Period: ~4.5 years

πŸ’° What Made the Difference?

βœ… Smart solar design matched to usage pattern
βœ… High daytime self-consumption (fridge, fans, appliances)
βœ… NEM program allowed selling unused solar back to TNB
βœ… Monitoring via app to adjust usage habits

It’s not just about the panels β€” it’s about using the right setup and strategy.


🧠 What This Means for You

Even homes with RM350+ monthly bills can see major results:

  • Cut electricity costs by 80–90%
  • Save RM5k–RM7k per year
  • Break even within 4–6 years
  • Enjoy 20+ years of low-cost energy after that
