Your solar developer's 25-year performance warranty is not insurance. It promises a level of output. It will not pay you for a lightning strike that destroys your inverters, a fire that starts at a DC arc fault on your roof, or the electricity savings you lose while a damaged system sits idle for three months.
Whether your solar project needs its own insurance comes down to one question: who owns the asset, and therefore who carries the risk when it is damaged or stops generating.
This guide is a decision framework for Malaysian businesses installing solar, whether that's a rooftop commercial and industrial system under net energy metering or a utility-scale plant under the Large Scale Solar programme. It explains when your existing cover is enough, when it isn't, and what to check before you assume you're protected.
Installing solar and unsure what your current policy actually covers?
The most common gap is a factory that adds a rooftop array worth millions without updating its fire and property programme. Emerge reviews solar exposure for Malaysian businesses and places dedicated cover where it's needed.
The decision: does your solar project need its own cover?
Start with ownership, because it determines everything else. Under most rooftop solar arrangements in Malaysia, you either buy the system outright as a capital expenditure, or you take it under a solar-as-a-service lease where a developer owns the hardware and sells you the power. Who insures what flows directly from that choice.
| Your situation | Who owns the asset | What you need to do |
|---|---|---|
| Bought the rooftop system outright (CAPEX) | You do | Extend your property cover or arrange dedicated solar cover, including business interruption |
| Leased under solar-as-a-service or a lease | The developer | Confirm in writing that the developer insures the asset, and check your liability for the roof and building |
| Developing a Large Scale Solar plant | You do, usually with debt | Arrange a bankable construction and operational programme; lenders will require it |
| Producer under the Corporate Green Power Programme | You do | Insure the asset and the contracted revenue under the virtual power purchase agreement |
If you lease the system, your job is verification, not procurement. Get the developer's insurance confirmed in writing, including whether it covers damage to your building caused by the array, and whether you carry any liability for a fire that starts in their equipment. A handshake is not a loss payee clause.
If you own the system, the rest of this guide is for you.
Why your fire policy probably isn't enough
A standard Malaysian fire policy covers three perils: fire, lightning and explosion. Flood, storm and tempest are not included automatically. They are special perils that must be added for an additional premium, and even the flood extension carries its own excess and excludes subsidence and landslip.
Now add a solar array to that building. You've increased the insured value of the property, sometimes by millions of ringgit, and you've changed its risk profile. Solar introduces direct-current fire risk at the panels, combiner boxes and inverters, a failure mode that standard commercial property underwriting was not written around. If you don't tell your insurer and update the sum insured, you risk underinsurance and a disputed claim.
Two perils matter more in Malaysia than buyers expect. Lightning density across parts of Peninsular Malaysia is among the highest in the world, which makes surge protection and proper earthing a genuine loss driver, not a formality. And ground-mount and floating solar are directly exposed to the flood and storm risk that the December 2021 floods showed can run into billions in national losses.
| Risk | Covered by standard fire policy? | What's needed |
|---|---|---|
| Fire and lightning | Yes, if sum insured is updated | Increase the sum insured to include the array |
| Flood and storm | No | Add special perils extension |
| Inverter or transformer breakdown | No | Machinery breakdown cover |
| Lost income or electricity savings | No | Business interruption cover, properly quantified |
| Theft of panels or cabling | No | Theft extension or all-risks cover |
| Serial or systemic component defect | No | Serial loss cover, where available, plus warranty management |
When underwriters price a solar risk in Malaysia, a handful of site factors do most of the work. Knowing them tells you where to invest before you buy cover.
| Pricing factor | Why it matters |
|---|---|
| Location and flood exposure | Ground-mount and floating systems in flood-prone areas carry materially higher expected loss |
| Surge protection and earthing | In a high-lightning country, proper protection is a real loss-control measure, not a formality |
| Component quality and track record | Panel and inverter brand history affects both breakdown risk and serial-defect exposure |
| Fire detection and DC isolation | Arc-fault detection and rapid shutdown reduce the most damaging rooftop fire scenarios |
| Business interruption values | Properly quantified income or savings let the policy actually replace what you lose offline |

The revenue you don't see until it's gone
For most solar buyers, the system pays for itself through avoided electricity cost or, under net energy metering, through export credits on the bill. That value disappears the moment the system goes offline, and property cover alone won't replace it.
Consider what happens after an insured event. Your property policy pays to repair or replace the damaged panels and inverters. But the three months your array sits idle while parts are sourced and installed, the savings or export credits you lose in that window, are not covered unless you arranged business interruption cover and quantified the income stream. For a large rooftop system on a manufacturing site, that lost value can be material.
Where the revenue depends on generation resource rather than the asset working, a different tool applies. A parametric policy can pay out when measured solar irradiance falls below an agreed level, addressing a low-generation year that no property policy would ever respond to. This is more relevant to utility-scale plants with revenue obligations than to a rooftop saver, but it's worth knowing the option exists.
Large Scale Solar and financed projects
If you're developing a utility-scale plant, the decision is already made for you. The Energy Commission's fifth Large Scale Solar round opened with a 2,000 MW quota, including a new floating solar category, with projects commissioning across 2026 and 2027. These are debt-financed assets, and lenders do not lend against an uninsured project.
The programme here mirrors any major construction project. During the build you need Erection All Risks cover with Delay in Start-Up protection, so that a flood or fire that pushes back commercial operation doesn't also blow up your debt service. Once operational, you move to property, machinery breakdown and business interruption. The bank will want to be named as loss payee and will review the programme against the facility terms.
Floating solar deserves a specific note. It concentrates value on water, adds marine and mooring exposures, and has a thinner global loss history, which makes underwriters more cautious and the placement more specialist. This is one of several cases where the broader renewable energy insurance market, including international capacity, becomes relevant rather than a standard domestic policy.
| Project phase | Core cover | What it protects on an LSS plant |
|---|---|---|
| Construction | Erection All Risks plus Delay in Start-Up | Damage to works during the build, and revenue lost if commissioning is delayed by an insured event |
| Operation | Operational property and machinery breakdown | The array, inverters and transformers against fire, storm, flood, lightning and sudden failure |
| Operation | Business interruption | Contracted revenue lost while the plant is offline, protecting debt service |
| Throughout | Lender-required structuring | The bank's security, with the lender named as loss payee and the programme reviewed against facility terms |
FAQ
Does a solar panel system need separate insurance in Malaysia?
It depends on who owns the system. If you bought it outright, your standard fire policy usually won't fully cover it, and you need to extend cover or arrange a dedicated solar policy. If you lease it under a solar-as-a-service arrangement, the developer typically owns and insures the asset, but you should confirm that in writing and check your liability for the roof and building.
Does a standard Malaysian fire policy cover rooftop solar?
Not automatically. A standard Malaysian fire policy covers only fire, lightning and explosion, and flood and storm must be added as special perils for an extra premium. A newly installed array also raises the building's value and changes its fire risk, so the sum insured and the terms need to be reviewed rather than assumed.
Is a solar developer's performance warranty the same as insurance?
No. A performance warranty is a promise about output, subject to its own conditions and the issuer's solvency. It doesn't pay for fire, storm or lightning damage, and it doesn't cover the revenue or savings you lose while a damaged system is offline. Warranties and insurance solve different problems, and you generally need both.
What insurance does a Large Scale Solar (LSS) project need in Malaysia?
An LSS project needs Erection All Risks and Delay in Start-Up cover during construction, then operational property, machinery breakdown and business interruption once it's generating. Lenders financing the project almost always require a bankable programme with the bank named as loss payee before releasing funds.
What are the main risks to solar panels in Malaysia?
The main risks are fire, including DC arc faults at the array and inverter, lightning damage in a country with very high lightning density, storm and flood damage to ground-mount and floating systems, and theft. Equipment breakdown of inverters and transformers, and the revenue lost while a system is offline, are the financial consequences that follow.
Does solar insurance cover loss of income or electricity savings?
It can, through business interruption cover, but only if that cover is arranged and the income or savings are quantified. For a system under net energy metering or a power purchase agreement, the lost export credits or contracted revenue can be insured, but the policy has to be structured for it. Standard property cover pays for the damage, not the lost income.
Emerge Conclusion
The solar decision is really an ownership decision. If you own the asset, your existing fire policy almost certainly doesn't cover it properly, and the revenue you're saving is exactly what's exposed when the system goes down. If you lease it, your job is to verify the developer's cover in writing rather than assume it.
The question to ask before your next installation is simple: if this array burned tomorrow, would my current policy pay to rebuild it and replace the electricity savings while it's down? If you're not sure, that's the gap to close.
