MLT Power

What MLT Power does

MLT Power is a South African turnkey solar energy solutions provider headquartered in Cape Town (97 Garfield Rd, Claremont, 7708) with service coverage across the Western Cape and the Johannesburg/Gauteng region. Founded in 1986 by Prof. Michel Malengret — an Emeritus Professor at the University of Cape Town specializing in power systems and inverters — the company is a family-owned business currently led by CEO Gerard Malengret and solar energy expert Jean-Claude Malengret. MLT Power sells and installs photovoltaic solar systems, inverters, battery storage, and microgrid control equipment, organized across three product lines: residential (6-50kW), commercial (30-200kW), and utility-scale (215kW+). Its technology stack is a multi-vendor, component-integrated architecture rather than a unified proprietary platform, combining branded components including Solis S6 Hybrid Inverters, Ario 215kW inverters, Weco and Juel lithium batteries, ARTSolar and Canadian Solar panels, and Lumax mounting systems. The company is a certified Tesla Powerwall 3 installer and offers proprietary integration through its Micro Grid Controller (MSC), which centralizes monitoring and control of grid, loads, solar inverters, battery inverters, and diesel generators with DNP3 protocol support for South African municipal requirements.

MLT Power generates revenue through two streams: hardware sales of solar panels, inverters, batteries, and mounting systems from a broad vendor portfolio, and professional installation services including system design, council approvals, compliance documentation, engineering sign-offs, and electrical certification. Pricing is quote-based and customized per project; system sizes and capacity ranges are disclosed but no unit pricing is publicly available. The go-to-market motion is sales-led, combining website quote requests, phone and email inquiry handling, on-site energy assessments, and direct consultations. Marketing channels are modest: SEO-optimized website, blog content, Facebook organic social, email communication, and a solar-branded vehicle wrap for mobile visibility in Cape Town. MLT Power claims more than 1,000 completed installations across South Africa over its 40+ year operating history and has 11-50 employees.

In 2014 the company received an undisclosed international capital investment that 'significantly boosted growth and market share,' coinciding with the leadership transition from the founder to Gerard Malengret as CEO. Operating geographies remain limited to two South African regions, with no indication of international expansion, additional institutional funding, or significant headcount scaling since 2014. No revenue, ARR, or financial performance figures are disclosed.

System monitoring is provided through the Solis Cloud Monitoring System and Micro Grid Controller (MSC). Panel options include ARTSolar (residential, South African-made) and Canadian Solar (commercial/utility, 500-630W). Mounting solutions come from Lumax Solar. The company also installs premium Tesla Powerwall 3 batteries, Deye hybrid systems, and Sigenergy high-capacity systems as part of their technology partnerships. Solar installation, compliance certification, and ongoing after-sales support are provided as services.

Direct peers

• ARTSolar: South African solar panel manufacturer that also operates an installation business. MLT Power is a customer of ARTSolar panels, but both compete in the residential and commercial solar market in South Africa with overlapping offerings.
• Traxsol: South African solar EPC serving residential, commercial, and industrial customers. Comparable in business model and product mix, with a similar focus on turnkey solar solutions in the South African market.
• Sunworx Energy Solutions: South African solar installer and energy solutions provider serving residential and commercial customers. Directly comparable in business model, customer segments, and regional market positioning to MLT Power.
• SolarAfrica: One of South Africa's largest residential, commercial, and utility-scale solar installers with a multi-region footprint. Directly competes with MLT Power across all three customer segments, with broader geographic reach and larger headcount.
• SolarJuice: South African solar retailer and installer focused on residential and small commercial systems. Competes with MLT Power in the residential segment with a more standardized, retail-oriented go-to-market model.
• Genergy: South African solar EPC and energy solutions provider serving commercial and industrial customers. Directly comparable in business model (turnkey solar installations) and target market (South African businesses seeking energy independence).

Broad incumbents

• Rubicon: South African energy and lighting distributor of which MLT Power is a certified channel partner. Rubicon offers solar and energy efficiency solutions across a broader portfolio, making it a broad incumbent that overlaps with MLT Power's offerings.

Others

• Canadian Solar: Major global solar panel manufacturer whose products MLT Power sells and installs. Not a direct competitor in installation but is a key supplier and an enabling ecosystem participant whose strategy impacts MLT Power's access and pricing.
• Tesla Energy: Global energy storage and solar manufacturer whose Powerwall products MLT Power is certified to install. Tesla is a strategic partner, but it could also enter the South African installation market directly, creating both upside and disintermediation risk.

Emerging players

• Sustainable.co.za: South African online retailer of solar, backup power, and energy efficiency products. Partially overlaps with MLT Power's residential solar offering but focuses more on equipment retail than full installation services.
