Is solar worth it?

Solar panels cost money upfront but cut your electricity bill for decades. The payback period is how long the savings take to cover the cost.

How it's calculated

Payback = system cost ÷ yearly bill savings. We also project the net savings over a 25-year panel lifetime after recovering the cost.

Frequently asked questions

How long is solar payback in Malaysia?

It varies with system size and usage, but many home systems pay back in roughly 5–8 years, then save money for the rest of their 25-year life.
