Solar Performance Guarantee Malaysia: What Homeowners Get

[Article updated June 2026]

Key Takeaways:
A solar performance guarantee in Malaysia ensures your solar system produces the energy it was designed to deliver, protecting homeowners from underperformance risk. GetSolar strengthens this with daily monitoring and compensation if output falls below 80% of the written projection..

What happens of the solar system on your roof produces less energy than promised? Under most contracts, that shortfall is your problem alone.

GetSolar's performance guarantee works differently. If your system's actual output falls below 80%  of the projection we commit to in writing, we compensate you for the difference — no technical disputes, no separate claim process.

Here's what causes underperformance in the first place, how the guarantee works, and how it fits into GetSolar's Rent-to-Own plans.

What Is a Performance Guarantee?

A solar performance guarantee is a promise that your solar system will produce a minimum expected amount of energy over time. It’s different from the warranties that come standard with any installation:

• Product warranty: covers defects in panels or inverters.
• Workmanship warranty: covers installation issues.
• Performance guarantee: ensures your system actually produces the energy you are promised.

In Malaysia, where landed homes vary widely in roof angles, shading, and weather exposure, this guarantee closes the gap between “your system should perform” and “if it doesn’t, you’re protected.”

Why Solar Performance Drop in Malaysia

Malaysia’s tropical climate creates real-world variables that can affect output:

• Heat and humidity reducing panel efficiency
• Heavy rain seasons decreasing sunlight hours
• Dust and haze, especially in urban areas
• Shading from trees or nearby structures
• Natural panel degradation over time

None of this means solar isn't worth it, Malaysia is becoming a solar leader in Southeast Asia, with strong government support and rapid growth in rooftop adoption. But a performance guarantee gives you added peace of mind, especially with policies like Solar ATAP (the scheme that replaced NEM 3.0 for new installations) still settling in through 2026.

How GetSolar's Performance Guarantee Works in Malaysia

GetSolar's guarantee is built around your actual energy yield, not just equipment condition:

• Your solar system’s expected performance is calculated using  Malaysia-specific data based on your roof's orientation, tilt, and shading profile.
• We monitor your system’s output continuously.
• If your system performs below 80% of that projection, we compensates you for the shortfall.

This guarantee sits on top of, not instead of:

• your panel warranty
• your inverter warranty
• free maintenance included in GetSolar’s Rent-to-Own (RTO) plans

In other words, the technical and financial risk of underperformance sits with us, not you.

Hardware Warranty vs. Performance Guarantee: What's the Difference?

A manufacturer warranty fixed a broken panel. A performance guarantee makes sure the system pays you back when the numbers fall short.

How the Guarantee Process Works

1. System Modelling: Before installation, we calculate a baseline energy projection using your roof's dimensions, orientation, tilt, and shading profile.
2. Continuous Monitoring: Your system's output is tracked on an ongoing basis.
3. Corrective Action: If a dip or fault is detected, our technical team services or repairs the system at no cost to you.
4. Performance Verification: Actual output is checked against the 80& baseline.
5. Compensation: If the system falls short of the threshold, the value of the missing energy is calculated and paid to you directly.

Real Malaysia Scenarios Where the Guarantee Helps

1. Unexpected Shading in a Subang Jaya Home

A neighbour builds a new extension that casts shade. System output drops below expectations.
→ GetSolar detects the drop and compensates the homeowner.

2. Higher-than-expected Dust Build-Up in Penang

Urban dust reduces efficiency more than estimated.
→ Output dips; compensation in triggered automatically.

3. Faster Panel Degradation in Johor’s Coastal Areas

Panels degrade quicker due to salty air.
→ Homeowner stays protected financially.

Across all three, the homeowner avoids loss and keeps their expected savings.

How This Fits With GetSolar’s Rent-to-Own Plans

GetSolar’s Rent-to-Own (RTO) plans already remove the biggest barrier to going solar: high upfront installation cost.

• 10-Year RTO: From RM267 monthly, RM0 upfront, 10 year workmanship warranty, performance guarantee and free maintenance included.
• 5-Year RTO: From RM167 monthly, ~50% upfront, 5 year workmanship warranty, performance guarantee and free maintenance included.

With the performance guarantee included, your RTO plan gives you a predictable monthly payment, continuous monitoring, and a financial backstop if output underperforms without needing to track any of if yourself.

Why First-Time Homeowners Should Care

If you’ve never installed solar, it’s normal to wonder what happens if something goes wrong, if the numbers don't add up, of it you don't end up saving as much as expected.

A performance guarantee addresses each of those directly: you get the energy you were promised, you're compensated if you don't, your long-term savings stay protected, and you don't need any technical knowledge to monitor the system yourself, GetSolar does that for you.
