Solar Energy Insurance in Malaysia: The Complete Coverage Guide for Developers, EPCC Contractors, and Asset Owners

Malaysia approved over 6,000 MW of large-scale solar capacity across six bidding rounds. Rooftop solar hit 1.72 GW by mid-2025, and Solar ATAP launched in January 2026 with no quota cap. Every megawatt commissioned needs insurance from day one of construction through 25 years of operations.

This guide covers the full insurance lifecycle for solar energy projects in Malaysia, from EAR during construction to machinery breakdown and business interruption during operations, so you know exactly what coverage to buy and when.

Whether you're an EPCC contractor bidding on an LSS project, a developer structuring finance for a ground-mounted farm, or a factory owner adding rooftop solar under Solar ATAP, the insurance requirements are different at every phase. Getting them wrong creates gaps that only surface at claims time.

Why solar energy projects need specialised insurance

Solar projects are capital-intensive, exposed to weather, and rely on mechanical and electrical equipment that degrades over time. A 30 MW ground-mounted solar farm can represent RM100 million or more in installed assets. A single severe storm, flood, or equipment failure can destroy millions in value and halt revenue generation for months.

Insurance isn't just risk management. For most solar projects in Malaysia, it's a contractual and financial requirement. Lenders mandate comprehensive coverage as a condition of project finance. Power Purchase Agreements (PPAs) with TNB or corporate offtakers require the project to maintain insurance throughout the contract term. Energy Commission licensing conditions also reference adequate insurance arrangements.

The challenge is that solar insurance isn't a single product. It's a stack of policies that changes depending on whether you're building or operating, whether you own the building or lease the roof, and whether you're a 5 kW residential system or a 50 MW utility-scale farm.

The two-phase insurance framework

Every solar project passes through two distinct insurance phases. The construction phase covers procurement, installation, testing, and commissioning. The operational phase begins at Commercial Operation Date (COD) and continues for the life of the project, typically 25 years or more.

Each phase has different risks, different insurance products, and different stakeholders responsible for arranging coverage. The table below maps the full lifecycle.

Phase	Coverage	What It Protects	Who Arranges
Construction	Erection All Risks (EAR)	Solar panels, inverters, transformers, mounting structures, cabling during installation and commissioning	EPCC contractor or developer
	Contractor's All Risks (CAR)	Civil works: access roads, fencing, substation building, earthworks, drainage	EPCC contractor or developer
	Marine Cargo	Transit of panels, inverters, and equipment to site	Supplier or EPCC contractor
	Third-Party Liability	Injury or property damage to third parties during construction	EPCC contractor
	Workmen Compensation	Worker injuries during construction	EPCC contractor
Operational	Fire Insurance + Special Perils	Physical damage from fire, lightning, explosion, flood, storm, and other named perils	Asset owner / developer
	Industrial All Risks (IAR)	Comprehensive property cover including accidental damage (wider than fire)	Asset owner / developer
	Machinery Breakdown	Sudden internal failure of inverters, transformers, tracking systems	Asset owner / developer
	Business Interruption / Loss of Production Income	Lost generation revenue during downtime from insured events	Asset owner / developer
	Electronic Equipment Insurance (EEI)	SCADA systems, monitoring equipment, communication and control systems	Asset owner / developer
	Third-Party Liability	Injury or property damage to third parties during operations and maintenance	Asset owner / developer

Construction phase: EAR, CAR, and the coverage you need before breaking ground

The construction phase of a solar project is when the highest-value equipment is most vulnerable. Panels are being handled, lifted, and mounted. Inverters and transformers are being installed and wired. Testing and commissioning expose equipment to electrical stress for the first time. All of this happens outdoors, exposed to weather.

Why EAR is the primary cover for solar construction

Solar farms are predominantly mechanical and electrical (M&E) installation projects. The panels, inverters, transformers, mounting structures, and cabling that make up 70-80% of a typical solar EPCC contract value are all erection works, not building construction. This means Erection All Risks (EAR) is the correct primary cover, not CAR.

This is a common mistake in Malaysia. Many EPCC contracts for solar projects specify CAR insurance because the contract template was originally drafted for building construction. Using CAR for what is fundamentally an M&E project can leave critical gaps, particularly around testing and commissioning coverage. For a detailed breakdown of when to use which policy, see our guide to EAR vs CAR for solar EPCC projects.

Coverage Feature	EAR	CAR
Solar panel installation	Covered (core scope)	May not adequately cover M&E erection works
Inverter and transformer erection	Covered (core scope)	May be excluded or limited
Testing and commissioning	Covered (standard inclusion)	Typically not included for M&E
Civil works (roads, fencing, earthworks)	Not primary scope	Covered (core scope)
Substation building	May need extension	Covered
Maintenance visit period	Standard (12-24 months typical)	Defects liability period

When you need both EAR and CAR

Most solar farm projects involve both M&E works and civil works. A typical ground-mounted installation includes access roads, perimeter fencing, a substation building, drainage systems, and earthworks alongside the panel arrays and electrical systems. The best approach is either a combined EAR/CAR policy or separate policies covering each scope.

For rooftop solar installations on existing buildings, EAR is usually sufficient. However, Section III (existing property coverage) must be included to protect the building itself from damage during installation. If the EPCC contractor's EAR policy doesn't include this, any damage to the factory roof during solar panel installation falls on the building owner's existing fire or IAR policy, or worse, falls into an uninsured gap.

Marine cargo and advance loss of profits

Solar panels and inverters are typically imported. Marine cargo insurance covers physical damage or loss during transit from the manufacturer to the project site. For large-scale projects where construction delays directly impact revenue, Advance Loss of Profits (ALOP) can be added as an extension to the EAR policy. ALOP covers the projected revenue that would have been earned during the period of delay caused by an insured construction loss.

Operational phase: protecting your solar assets for 25+ years

Once a solar project reaches COD, the EAR policy expires and operational coverage takes over. This transition is critical. There should be no gap between the expiry of construction coverage and the inception of operational policies. Some developers fail to have operational cover in place by COD, creating an uninsured window where their most expensive assets are exposed.

Fire insurance and special perils

Fire insurance is the baseline operational cover. It protects against fire, lightning, and explosion. For solar projects in Malaysia, lightning coverage is particularly important. Malaysia sits in the tropical thunderstorm belt with one of the highest lightning densities in the world. Lightning strikes can damage panels, surge through inverters, and destroy transformer insulation.

Standard fire insurance does not cover flood, storm, or windstorm. These must be added as special perils extensions, and for solar farms in Malaysia, they're essential. The December 2021 floods demonstrated the scale of flood risk to industrial and energy assets nationwide. Solar panels submerged in floodwater, inverters waterlogged, and erosion undermining mounting structures are all realistic scenarios.

Each item on the fire schedule carries its own sum insured, and the average clause applies independently to each item. If your panels are adequately insured but your inverters are underinsured, only inverter claims get penalised. Structure your fire schedule carefully with separate items for panels, inverters, transformers, mounting structures, and cabling.

When to upgrade to Industrial All Risks (IAR)

IAR provides broader coverage than fire insurance. Beyond the named perils in a fire policy, IAR covers accidental damage from a wider range of causes. For high-value solar installations, IAR is often the better choice because it covers scenarios that fire plus special perils would miss.

The key advantage for solar: IAR typically includes machinery breakdown as a covered peril, meaning you may not need a separate MB policy. It also offers an 85% co-insurance tolerance, so if your sum insured is at least 85% of the actual value, the average clause doesn't apply. For a deeper comparison, see our guide on when fire insurance isn't enough.

Machinery breakdown: the most critical operational cover

Inverters are the heart of a solar installation and the component most likely to fail. While solar panels are designed to last 25 years or more with gradual degradation, inverters have a typical operational lifespan of 5 to 10 years. Replacement costs range from tens of thousands to millions of ringgit depending on capacity. Transformers, while more robust, can fail from overheating, insulation breakdown, or lightning-induced surges.

Machinery breakdown (MB) insurance covers sudden and unforeseen physical damage from internal causes: electrical faults, short circuits, mechanical failure, centrifugal force, and defective materials. It does not cover wear and tear, gradual deterioration, or routine maintenance items. For solar-specific applications, the key equipment covered includes inverters (string, central, and micro), step-up transformers, tracking system motors and actuators, switchgear, and battery energy storage systems (BESS).

If you're running a solar project without MB coverage, you're self-insuring the most failure-prone component in your installation. For a detailed look at what MB covers and how it works, see our machinery breakdown guide for solar energy systems.

Business interruption and loss of production income

Solar farms generate revenue every hour of sunlight. When equipment fails or physical damage halts generation, the revenue loss is immediate and unrecoverable. Unlike a factory that can run overtime to catch up on lost production, every kilowatt-hour a solar farm doesn't generate during an outage is gone permanently.

Business interruption (BI) insurance for solar projects covers lost generation revenue during downtime caused by an insured event. The revenue calculation is based on projected generation (using historical solar irradiance data and system capacity) multiplied by the applicable tariff rate. For projects under PPA contracts, the financial exposure extends beyond lost revenue to include potential penalty clauses for failing to meet minimum generation commitments.

A related but distinct cover is Machinery Loss of Profits (MLOP), which specifically covers revenue loss caused by machinery breakdown events. Since inverter and transformer failures are the most common cause of extended solar farm downtime, MLOP is often as important as standard BI for solar operators. The indemnity period must account for equipment procurement lead times: replacement inverters can take 3 to 6 months to source and install, and custom transformers may take even longer.

Key risks for solar projects in Malaysia

Understanding the specific risks that affect solar installations in Malaysia helps you structure coverage appropriately. The risk profile here differs from temperate markets. Hail, which is the number one cause of solar insurance claims globally, is rare in Malaysia. Instead, the dominant risks are flooding, lightning, and equipment failure.

Risk	Impact on Solar Assets	Insurance Response
Flooding	Panel submersion, inverter waterlogging, mounting structure erosion, cable damage	Fire + special perils (flood extension) or IAR
Lightning and electrical surge	Inverter damage, transformer insulation failure, SCADA system destruction	Fire insurance (lightning is a standard peril) + MB for internal equipment damage
Windstorm	Panel displacement, mounting structure failure, debris impact	Special perils extension (storm/tempest)
Inverter failure	Generation halt for affected strings or entire farm; 3-6 month replacement lead time	Machinery Breakdown + MLOP for revenue loss
Transformer failure	Complete generation halt; 6-12 month lead time for custom units	Machinery Breakdown + MLOP
Theft	Cable theft, panel theft at remote ground-mounted sites	IAR (typically includes theft); fire policy may need specific endorsement
Thermal cycling and degradation	Micro-cracking, hotspot formation, gradual efficiency loss	Generally excluded (wear and tear); manufacturer warranty applies

Structuring coverage by project size

The insurance approach varies significantly depending on project scale. A 10 kW rooftop system on a shophouse has fundamentally different insurance needs from a 50 MW LSS farm. Here's how to think about coverage by project tier.

Project Type	Typical Size	Recommended Coverage
Commercial rooftop	10 kW - 1 MW	Add solar PV to existing fire policy as separate schedule item + MB for inverters. Consider a packaged Solar PV All Risk policy for simplicity.
Industrial rooftop	1 MW - 5 MW	Fire + special perils (with solar as separate item) + MB + BI extension for savings/revenue protection. Review existing IAR if already in place.
Medium ground-mount	5 MW - 30 MW	IAR (preferred over fire for breadth of cover) + MB/MLOP + CGL + EEI for monitoring systems.
Large-scale solar (LSS)	30 MW+	IAR + MB + MLOP + BI/Loss of Production Income + CGL + EEI. Lender-mandated structure with minimum coverage requirements, assignment clauses, and agreed indemnity periods.

For factory owners adding rooftop solar under Solar ATAP, the process is more straightforward than it appears. In most cases, you're updating your existing fire or IAR policy rather than buying new coverage from scratch. See our dedicated guide on rooftop solar insurance for factory and building owners.

What lenders and PPAs require

If your solar project involves bank financing or a corporate PPA, the insurance requirements are not optional. They're contractually embedded. Lenders and offtakers need assurance that their investment or supply commitment is protected even if something goes wrong with the physical assets.

Requirement	Typical Lender Expectation	Why It Matters
Property All Risks / IAR	Full reinstatement value coverage for all project assets	Protects collateral value
Machinery Breakdown	Coverage for all critical M&E equipment	Inverters and transformers are the highest-risk components
BI / Loss of Production Income	Minimum indemnity period (often 18-24 months)	Ensures debt service can continue during extended outages
Third-Party Liability	Minimum coverage limit (varies by project size)	Protects against litigation that could impair project viability
Policy assignment	Lender named as loss payee and/or co-insured	Ensures claim proceeds go toward project restoration, not diversion
Broker's undertaking	Insurance intermediary confirms coverage in place and will notify lender of any changes	Provides lender with ongoing insurance monitoring without direct policy access

Getting the insurance structure right at the financing stage saves significant renegotiation later. If your lender's insurance advisor flags gaps after financial close, resolving them under time pressure almost always costs more than structuring properly upfront.

Common mistakes in solar energy insurance

These are the gaps we see most frequently when reviewing solar project insurance in Malaysia.

Mistake	Consequence	How to Avoid
Using CAR instead of EAR for solar EPCC	Testing and commissioning of M&E not covered; claims during energisation declined	Ensure EPCC contract specifies EAR as primary cover for M&E scope
No operational cover at COD	Gap between EAR expiry and operational policy inception; assets uninsured	Arrange operational policies to incept on or before COD; coordinate with EAR broker
No machinery breakdown cover	Inverter failure (most common claim) is entirely self-insured	Add MB policy or use IAR which typically includes MB as a covered peril
Underinsured sum on fire schedule	Average clause reduces claim payout proportionally	Declare full reinstatement value for each item; review annually as equipment costs change
BI indemnity period too short	Revenue loss continues after BI coverage expires; custom transformer replacement can take 12+ months	Set indemnity period based on worst-case equipment replacement time, not average
Rooftop solar not added to building's fire schedule	Solar PV system is completely uninsured under existing building policy	Notify insurer and add solar PV as separate item on fire schedule immediately after installation
No flood extension in special perils	Flood damage to ground-mounted panels and inverters not covered under basic fire policy	Always include flood, storm, and tempest as special perils for Malaysian solar projects

FAQ

What insurance does a solar farm need in Malaysia?

A solar farm needs EAR or CAR insurance during construction, then fire or IAR plus machinery breakdown, business interruption, and third-party liability during operations. The exact structure depends on project size, financing requirements, and whether the project is ground-mounted or rooftop.

Is EAR or CAR the right insurance for solar EPCC construction?

EAR is the correct primary cover for solar EPCC projects because the work is predominantly mechanical and electrical installation, not building construction. CAR may be needed alongside EAR for civil works like access roads and substation buildings. Many EPCC contracts mistakenly specify CAR only.

Does fire insurance cover solar panels?

Fire insurance covers solar panels against fire, lightning, and explosion only if the solar PV system is declared as a separate item on the fire schedule with an adequate sum insured. It does not cover mechanical breakdown, theft, flood, or storm damage without additional extensions or a separate policy.

What is the most common insurance claim for solar farms?

Globally, natural catastrophe damage (particularly hail and storm) accounts for the majority of solar insurance claims by value. In Malaysia, the more relevant risks are flooding, lightning surge damage, and inverter or transformer failure. Machinery breakdown claims for inverters are among the most frequent operational claims.

Do I need machinery breakdown insurance for solar panels?

Solar panels themselves rarely suffer from mechanical breakdown, as they have no moving parts. However, inverters, transformers, tracking system motors, and battery storage systems do fail. Machinery breakdown insurance is essential for these components, which represent significant replacement costs and long lead times.

What insurance do I need to add rooftop solar to my factory?

You need to update your existing fire or IAR policy by adding the solar PV system as a separate item on your fire schedule. You should also consider machinery breakdown for the inverter and a business interruption extension for lost energy savings. During installation, verify that the EPCC contractor's EAR policy includes Section III coverage for your existing building.

What is loss of production income insurance for solar?

Loss of production income insurance covers lost generation revenue when a solar farm cannot produce electricity due to an insured event. The payout is calculated based on projected generation (kWh) multiplied by the applicable tariff rate, minus any actual generation during the outage period. It's distinct from standard BI in that it uses energy production data rather than accounting-based gross profit calculations.

Does solar panel insurance cover degradation or efficiency loss?

No. Gradual degradation and efficiency loss over time are considered wear and tear, which is a standard exclusion in all property and machinery breakdown policies. Panel performance degradation is covered by the manufacturer's product warranty, not by insurance. Insurance responds to sudden and unforeseen events, not gradual processes.

Foundation Conclusion

Solar energy insurance in Malaysia isn't a single product but a structured stack that evolves from construction through decades of operations. The projects are getting larger, the regulatory framework is maturing, and the financial stakeholders demand comprehensive coverage as a baseline.

Getting the insurance structure right from the start, choosing EAR over CAR for construction, ensuring operational coverage is in place before COD, and building a machinery breakdown and business interruption layer that reflects actual equipment lead times, is what separates a bankable project from one that discovers its gaps at claims time.
