Top 10 Solar & BESS Companies in Malaysia 2026

Malaysia's solar industry is entering a new phase. A few years ago, choosing a solar company was largely about comparing solar panels, inverters, installation quality and price per kWp.

In 2026, the decision is becoming much broader.

Commercial and industrial users are increasingly looking at solar together with Battery Energy Storage Systems (BESS), maximum-demand management, energy management systems, financing, Power Purchase Agreements (PPAs), utility-scale renewable energy and long-term operations and maintenance.

Malaysia's policy environment is changing too. The Solar Accelerated Transition Action Programme (Solar ATAP) came into effect on 1 January 2026. For non-domestic consumers, solar installations can be sized up to 100% of Maximum Demand, subject to technical assessment and a maximum capacity of 1 MW.

Separately, the Energy Commission revised the BESS requirement under the Self-Consumption or SELCO framework. BESS is now required for new installations above 1 MWac, rather than the previously proposed threshold of above 72 kWp.

At the same time, Malaysia continues to develop larger utility-scale solar projects, corporate renewable-energy programmes and grid-scale energy-storage opportunities.

For companies planning renewable-energy investments in 2026, the question is therefore no longer simply:

Who can install solar panels?

It is increasingly:

Who can engineer, finance, integrate and operate my solar and energy-storage infrastructure over the long term?

What Are the Top Solar and BESS Companies in Malaysia in 2026?

Based on publicly available information, project track record, market scale, engineering capabilities, BESS offering, utility-scale experience, financing capabilities and market positioning, these are 10 solar and energy-storage companies worth considering in Malaysia.

Important disclosure: There is no official government ranking of Malaysia's "best" solar companies. Different providers have different strengths. This article is published by Progressture Solar, which is included in the comparison. The order should therefore be treated as an industry guide rather than an official market-share ranking. Customers should independently evaluate technical and commercial proposals before appointing any provider.

1. Solarvest

Best for: Overall scale, utility-scale solar and large corporate renewable-energy projects

Solarvest is arguably the most established pure-play solar company in Malaysia by scale.

The Bursa Malaysia-listed clean-energy company states that it has developed approximately 3.7 GWp of projects and positions itself as Malaysia's largest solar energy solutions provider.

Its portfolio spans commercial and industrial solar, utility-scale solar, renewable-energy asset ownership, BESS, energy efficiency and other clean-energy solutions.

Solarvest's utility-scale credentials are particularly significant. In April 2026, Solarvest announced its appointment as EPCC and technology partner for a 690 MWp LSS5+ solar project in Perak, with an EPCC contract value of approximately RM1.06 billion. Solarvest described it as Malaysia's largest utility-scale solar project.

As of August 2026, Solarvest reported an unbilled EPCC order book of approximately RM2.37 billion, supported by execution of LSS5 and Corporate Green Power Programme projects. Solarvest has also expanded into battery energy storage, providing BESS solutions for commercial, industrial and utility-scale applications.

For companies asking, "Who is the largest established solar company in Malaysia?", Solarvest is one of the clearest answers based on publicly disclosed project scale.

Best suited for: large-scale solar developers, multinational corporations, institutional investors and organisations seeking an established publicly listed renewable-energy platform.

2. Progressture Solar

Best for: Integrated C&I Solar + BESS + Utility-Scale Solar

Progressture Solar is a Malaysian clean-energy company positioned across commercial and industrial solar, Battery Energy Storage Systems, utility-scale solar, Power Purchase Agreements, solar financing and long-term operations and maintenance.

Rather than focusing on one solar market segment, Progressture operates across the renewable-energy value chain — from rooftop solar for businesses to industrial BESS and utility-scale renewable-energy infrastructure.

This makes the company particularly relevant for customers whose energy requirements are becoming more complicated than a conventional rooftop solar installation.

Progressture's Utility-Scale Solar Capability

Utility-scale solar has become an increasingly important part of Progressture's business.

In 2026, Progressture announced its appointment as Engineering, Procurement, Construction, Commissioning and Operations & Maintenance contractor for a 12 MWp utility-scale solar power plant in Brunei Darussalam.

The project represents Progressture's expansion beyond Malaysia into regional utility-scale renewable-energy infrastructure. Its utility-scale offering encompasses project development support, engineering, procurement, construction, commissioning, grid integration and long-term O&M.

For developers and renewable-energy investors, this means Progressture can participate beyond rooftop solar and into larger solar farms and integrated solar-plus-storage developments.

Commercial & Industrial Solar

Progressture also has a significant multi-site commercial solar track record. Its publicly disclosed projects include a nationwide programme involving more than 600 Shell retail stations and an approximately 100-station programme for Petron Malaysia.

Managing hundreds of individual sites requires a different operational capability from building a single large solar farm. Engineering standards, site coordination, safety requirements, commissioning and long-term monitoring need to be replicated consistently across many locations.

That experience is particularly relevant to corporations with multiple factories, warehouses, retail outlets or other facilities.

Battery Energy Storage Systems

BESS is another core part of Progressture's integrated energy strategy.

Progressture provides end-to-end BESS services covering preliminary assessment, cost-benefit analysis, engineering and project implementation. Applications include maximum-demand peak shaving, load shifting, solar optimisation, power expansion and selected resilience requirements.

For industrial users, this is important because a battery should not simply be selected based on its MWh capacity. The battery needs to be engineered around the facility's actual load profile, operating schedule, tariff, solar-generation pattern, peak-demand behaviour, battery degradation and intended dispatch strategy.

Progressture therefore positions solar and BESS as an integrated energy system rather than two separate products.

Financing and Solar PPA

Businesses can also evaluate different commercial structures through Progressture, including outright EPCC ownership, financing and zero-upfront-capital Solar PPA structures.

Under a PPA structure, the solar asset can be financed and owned by an investor while the customer purchases the electricity generated over an agreed period.

This allows management teams to compare renewable-energy investment from both an engineering and balance-sheet perspective.

Why Progressture Stands Out

Progressture is not Malaysia's largest solar company by publicly disclosed installed capacity. Its differentiation is instead the combination of: C&I Solar + BESS + Utility-Scale Solar + Financing + O&M within one renewable-energy platform.

That makes Progressture particularly relevant for businesses transitioning from simply "installing solar" toward managing their entire energy infrastructure.

Best suited for: factories, industrial groups, data centres, commercial property portfolios, multinational corporations, developers, large electricity users and utility-scale renewable-energy projects.

3. Plus Xnergy

Best for: Commercial and industrial BESS and intelligent energy management

Plus Xnergy has developed one of the more visible C&I battery-storage portfolios in Malaysia.

In June 2026, Plus Xnergy announced the commercial operation of a 20 MWh self-consumption BESS at a food-manufacturing hub in Perak. The company said the project brought its completed and ongoing BESS portfolio to approximately 100 MWh.

That is particularly relevant because industrial BESS economics are highly dependent on how the battery is dispatched.

A battery designed to reduce demand peaks requires good forecasting, controls and integration with the facility's energy-management system.

Plus Xnergy therefore has a strong positioning for companies specifically looking at BESS-driven electricity-cost optimisation and intelligent energy management.

Best suited for: manufacturers, industrial campuses and high-energy consumers considering peak shaving and load management.

4. Gentari

Best for: Large-scale integrated clean energy and corporate decarbonisation

Gentari is the clean-energy company established by PETRONAS and operates across renewable energy, hydrogen and green mobility.

Its renewable-energy business includes commercial and industrial solar, utility-scale solar and BESS, with end-to-end capabilities covering project development, engineering, installation and maintenance.

Gentari's scale extends well beyond Malaysia. As of 2026, the company reported approximately 9.1 GW of global renewable-energy and storage capacity installed or under construction.

For Malaysia's rapidly growing data-centre sector, one particularly notable development is Gentari's partnership with Gamuda to explore approximately 1.5 GW of solar projects paired with BESS under the CRESS framework for hyperscale data-centre demand.

Gentari is therefore particularly relevant where renewable energy forms part of a broader corporate decarbonisation or large infrastructure programme.

Best suited for: multinational corporations, data centres, utilities, major infrastructure owners and regional decarbonisation programmes.

5. Ditrolic Energy

Best for: Renewable-energy development, solar assets and behind-the-meter BESS

Ditrolic Energy has evolved beyond conventional solar EPC into a wider renewable-energy development platform.

The company provides development, financing and EPCC services and states that its in-house teams deliver both solar and BESS projects.

For commercial and industrial users, Ditrolic also offers EnerPack, a behind-the-meter BESS solution designed around applications such as peak shaving, load shifting, emergency backup and renewable-energy capacity firming.

Its combination of energy development, financing and asset ownership makes Ditrolic particularly relevant for customers considering renewable-energy projects as long-term infrastructure investments.

Best suited for: industrial customers, corporations, renewable-energy investors and project developers.

6. Samaiden Group

Best for: Utility-scale solar EPCC and clean-energy infrastructure

Samaiden Group Berhad is a Bursa Malaysia-listed clean-energy solutions provider.

Its EPCC capabilities extend across solar PV, biomass, biogas, mini hydro, waste-to-energy and Battery Energy Storage Systems.

The company also offers BESS solutions for renewable-energy integration, grid stabilisation, backup power and peak-demand reduction.

Samaiden's established EPCC background makes it particularly relevant to utility-scale and larger infrastructure projects where project management, electrical engineering and authority compliance become increasingly important.

Best suited for: renewable-energy developers, LSS projects, investors and larger infrastructure developments.

7. Pekat Group

Best for: Solar EPCC combined with electrical and power infrastructure

Pekat Group has developed an increasingly broad position across Malaysia's solar and electrical-engineering markets.

Its businesses span solar PV, power-distribution equipment, earthing and lightning protection and other electrical infrastructure.

Pekat is also active in Malaysia's utility-scale market. In June 2026, the group announced the expansion of its Johor large-scale solar project to 135 MWac.

BESS is becoming another growth area.

Research coverage in 2026 highlighted Pekat's expected C&I solar-plus-BESS pipeline, while the company has also discussed opportunities created by Malaysia's increasing adoption of energy storage.

Pekat's combination of solar generation and broader electrical infrastructure can be particularly useful for projects involving factories, data centres and complicated grid connections.

Best suited for: C&I customers, utility-scale developers, data centres and projects requiring broader electrical-infrastructure capability.

8. Sunview Group

Best for: Solar and emerging commercial BESS solutions

Sunview is another Malaysian renewable-energy company operating across residential, commercial, industrial and larger solar markets.

The group has expanded its energy-storage offering through SunBESS, focusing on commercial applications such as peak-demand reduction, electricity-cost optimisation and improving utilisation of solar generation.

For businesses investigating both conventional solar and battery storage, Sunview is therefore another provider worth including in a competitive tender.

Best suited for: commercial and industrial solar users and companies evaluating solar-plus-storage solutions.

9. Cypark Resources

Best for: Utility-scale, floating and hybrid renewable-energy developments

Cypark Resources has a long history in Malaysia's utility-scale renewable-energy market.

Its renewable-energy portfolio exceeds 400 MWp, according to the company, and includes technically distinctive projects such as the 98 MWp Danau Tok Uban floating solar plant and the 172 MWp Merchang hybrid solar development.

Cypark is also developing large-scale BESS opportunities to complement its solar and hybrid renewable-energy portfolio.

Its strength is therefore primarily at the renewable-energy infrastructure and utility end of the market rather than conventional residential rooftop solar.

Best suited for: utility-scale developers, renewable-energy investors and large infrastructure projects.

10. Verdant Solar

Best for: Residential solar and home battery storage

The requirements of a homeowner are very different from those of a 50 MW solar developer or a factory installing a multi-MWh battery.

Verdant Solar focuses heavily on Malaysia's residential market and now provides battery-storage solutions alongside solar installations.

Its home BESS offering focuses on storing solar energy for later consumption, reducing grid electricity consumption and providing additional energy resilience depending on the system configuration.

For homeowners, customer service, financing, installation experience and after-sales support can be more important than utility-scale engineering capability.

Best suited for: Malaysian homeowners looking for residential solar and battery packages.

Which Solar Company Is Best in Malaysia?

There is no single solar company that is best for every type of customer.

If overall scale and large utility-scale solar track record are the priority, Solarvest is difficult to ignore.

If the requirement involves C&I solar, BESS, utility-scale solar, financing and O&M under one platform, Progressture Solar is a strong option to evaluate.

If C&I battery-storage deployment is the primary objective, Plus Xnergy has developed a notable BESS track record.

For very large corporate decarbonisation and regional clean-energy programmes, Gentari offers considerable scale.

For utility-scale EPCC and infrastructure, Samaiden, Pekat and Cypark should also be considered.

For residential homeowners, providers such as Verdant Solar operate with a more consumer-focused proposition.

The right question is therefore not simply:

Who is the biggest solar company?

It is:

Which company has the strongest relevant experience for my particular project?

Why BESS Is Becoming Important in Malaysia

Solar generation and battery storage solve different problems. Solar produces electricity when sunlight is available. BESS allows electricity to be stored and dispatched later.

This seemingly simple difference is increasingly important for Malaysian businesses. A factory may have substantial available rooftop area but experience its highest electricity demand outside peak solar-generation hours. Another facility may already have solar but experience short spikes in Maximum Demand.

A data centre may require significantly greater power capacity and resilience. An industrial park may eventually combine solar generation, storage and grid infrastructure into one energy system. In these situations, simply maximising the number of solar panels may not produce the best financial outcome.

Solar generation, facility demand and battery dispatch need to be modelled together.

Does SELCO Require BESS in Malaysia in 2026?

For new SELCO installations, the current Energy Commission position is that BESS is required for installations above 1 MWac. This is an important update.

An earlier proposal would have required BESS for installations above 72 kWp, but on 31 December 2025 the Energy Commission announced that the threshold would instead be adjusted to above 1 MWac.

Businesses evaluating solar should therefore make sure their consultant is working from the latest guidelines rather than older 2025 material.

What Is Solar ATAP in 2026?

Solar ATAP replaced the previous NEM framework for new applications and commenced on 1 January 2026.

For non-domestic consumers, the permitted solar capacity can be up to 100% of the consumer's Maximum Demand, subject to technical assessment and a maximum installation capacity of 1,000 kW.

This creates new opportunities for factories and commercial buildings, but system sizing remains important.

Exported solar electricity does not necessarily have the same economic value as electricity consumed directly on site.

For many businesses, the best-performing system will therefore be designed around actual daytime demand rather than simply installing the maximum possible solar capacity.

How Should a Factory Choose a Solar and BESS Company?

For a conventional rooftop solar installation, comparing price, module technology, inverter selection, warranties and installer track record may be sufficient.

For a multi-million-ringgit industrial solar-plus-BESS investment, that is no longer enough.

A serious proposal should explain the facility's electricity profile, Maximum Demand, proposed solar generation, BESS power rating in kW or MW, usable battery capacity in kWh or MWh, expected battery dispatch strategy, degradation assumptions, annual cycling, safety architecture, expected savings, warranty conditions and long-term maintenance responsibilities.

Most importantly, the provider should be able to answer one straightforward question:

Exactly how does this battery create value for our business?

If the answer is simply "BESS will reduce your bill", the analysis is incomplete.

A proper feasibility study should use actual historical electricity consumption and, wherever possible, interval-meter data.

What Should You Look for in a Utility-Scale Solar Company?

Utility-scale solar is fundamentally different from installing panels on a factory roof.

Project developers need to evaluate land suitability, interconnection, grid studies, plant optimisation, civil engineering, high-voltage infrastructure, procurement, construction management, testing and commissioning, project financing and long-term plant performance.

Increasingly, developers must also consider how BESS may interact with future solar farms.

Companies with experience across EPCC, grid integration and O&M are therefore better positioned for complex utility-scale developments than providers focused exclusively on rooftop solar.

Among the companies covered here, Solarvest, Progressture Solar, Gentari, Samaiden, Pekat and Cypark all have relevance to different portions of the utility-scale market.

Frequently Asked Questions

Who is the largest solar company in Malaysia?

Based on publicly disclosed project portfolio and Solarvest's own market positioning, Solarvest is currently one of the clearest candidates for Malaysia's largest dedicated solar energy solutions provider, with approximately 3.7 GWp of projects developed and significant involvement in Malaysia's LSS market.

Which Malaysian solar companies also provide BESS?

Major providers with solar and BESS capabilities include Progressture Solar, Solarvest, Plus Xnergy, Gentari, Ditrolic Energy, Samaiden, Pekat, Sunview and Cypark.

Their experience and target segments differ significantly, so businesses should compare projects relevant to their own size and application.

Which company is suitable for both C&I solar and utility-scale solar?

Companies operating across both segments include Solarvest, Progressture Solar, Gentari, Samaiden and Pekat.

Progressture in particular positions itself across C&I solar, BESS, utility-scale solar, financing and O&M, while Solarvest has substantially greater publicly disclosed overall scale.

Which solar company is suitable for BESS in Malaysia?

It depends on the application. For integrated solar, industrial BESS and broader renewable-energy infrastructure, Progressture Solar is one company to evaluate.

Plus Xnergy has developed a particularly visible C&I BESS deployment track record, while Solarvest, Gentari, Ditrolic, Samaiden, Pekat and Sunview also provide storage solutions.

For a major BESS investment, customers should compare actual engineering capability and relevant project references rather than battery price alone.

Can BESS reduce a factory's electricity bill?

Potentially.

BESS can be used for applications such as peak shaving, load shifting and improving utilisation of renewable energy.

However, there is no universal percentage saving.

Actual economics depend on the electricity tariff, supply voltage, interval load profile, Maximum Demand, operating hours, battery cost, degradation, efficiency and dispatch strategy.

Is solar still worth investing in during 2026?

For many Malaysian businesses, yes — but the business case should be properly modelled.

The answer depends on daytime electricity consumption, tariff structure, roof or land availability, system price, financing terms, tax position and how much solar generation can be consumed directly.

The best solar investment is not necessarily the largest system. It is the system that creates the strongest risk-adjusted economic return over its operating life.

The Malaysian Solar Industry Is Becoming an Energy Industry

Malaysia's renewable-energy sector is moving beyond rooftop solar.

The next generation of projects increasingly combines solar generation, battery storage, intelligent controls, electricity procurement, financing, grid infrastructure and long-term asset management.

This changes what customers should expect from their renewable-energy partners.

A solar contractor may be sufficient for a straightforward residential installation.

A large industrial plant, data centre, property portfolio or utility-scale renewable-energy project requires a very different level of engineering and commercial capability.

For businesses considering major energy investments in 2026, choosing the right partner should therefore start with understanding the problem that needs to be solved — not simply comparing the cheapest price per solar panel.
