SunRoof is a technology company.
SunRoof develops and manufactures integrated solar roofing systems, creating building-integrated photovoltaics (BIPV) that function as both roof and efficient energy generator. Their product embeds photovoltaic cells directly within the structure, offering sleek aesthetics, high electricity generation, and thermal insulation. This innovative approach transforms buildings into self-sufficient energy producers, seamlessly integrating renewable energy into architectural design without compromising functionality or visual appeal.
Founded in 2013 by Marek Zmysłowski, Karol Kaniuk, and Martyn Szczepankowski, SunRoof emerged from the insight to move beyond traditional bolt-on solar panels. The founders envisioned roofs as active power sources, aiming to design solar solutions that fully replace conventional materials. This integrated approach combines advanced technology with architectural demands for both structural protection and optimal energy efficiency.
SunRoof's integrated solar solutions cater to private homeowners, property developers, and managers of commercial and public buildings. Customers seek sustainable materials that perform robustly and enhance aesthetic appeal. The company's vision is to facilitate a global transition to renewable energy by making every building a potential power plant, fostering energy independence, and significantly reducing carbon footprints worldwide.

SunRoof is a technology company specializing in building-integrated photovoltaics (BIPV), developing 2-in-1 solar roofs that replace traditional roofing while generating renewable energy. These products serve private homes, commercial buildings, developers, and public structures in the renewable energy and construction sectors, solving the problem of inefficient, high-carbon roofing by providing energy-efficient, weatherproof alternatives with low carbon footprints.[1][2][3] With over 1,000 solar roofs sold worldwide and operations in Sweden, Germany, and Poland (with a hub in Poland), SunRoof has raised over €35 million from investors like Nordic Alpha Partners and Klima Energy Transition, achieving exponential growth as the fastest-growing BIPV company.[2][3][5]
SunRoof was founded by brothers Karol and Lech Kaniuk, with Lech serving as CEO, driven by a mission to enable green transformation through innovative solar tech. Sources vary slightly on the founding year—2013 per some records or 2020 per others—but the company originated in Vänersborg, Sweden, as a solar roof developer merging construction with digital energy management.[1][2][5] Early traction came from proprietary roof-tile technology that powers homes and links them into virtual power plants for selling surplus energy, leading to €4.5M seed funding in 2019 and a €15M round later. Pivotal growth hit in recent years, expanding to Poland and Germany amid rising BIPV demand.[2][5]
SunRoof rides the global shift to renewable energy and BIPV, fueled by climate goals, EU green policies, and demand for carbon-neutral buildings amid energy crises. Timing aligns with solar cost drops and construction electrification trends, positioning it against competitors like Solarstone and Autarq in a market projected for rapid BIPV adoption.[1][2] It influences the ecosystem by pioneering 2-in-1 solutions that merge digital energy management with physical infrastructure, inspiring decentralized grids and reducing reliance on fossil fuels while supporting community climate initiatives.[2][3]
SunRoof is poised to dominate BIPV expansion, targeting deeper penetration in Poland/Germany and new markets with its proven model. Trends like AI-optimized energy grids, stricter carbon regs, and home electrification will accelerate growth, potentially scaling to utility-level virtual plants. Its influence may evolve from niche innovator to mainstream enabler of fossil-free buildings, building on current momentum to redefine roofing as energy infrastructure.[2][3]
