Description
Natural Green Energy (NGE) is a company specializing in the distribution and implementation of ultra-lightweight, thin-film photovoltaic panels based on CIGS technology, manufactured in Europe. We deliver modern energy solutions for commercial and industrial buildings as well as the mobility sector, focusing on applications where traditional photovoltaic systems cannot be installed due to weight limitations, structural constraints, or technical challenges.
Our modules feature an ultra-thin design (approx. 2 mm) and an exceptionally low weight of around 3 kg/m². This allows installation on roofs with limited load-bearing capacity without the need for structural reinforcement. The panels are mounted directly by bonding to the roof surface – without frames, without ballast, and without penetrating the waterproofing layer. This makes them particularly suitable for membrane roofs (PVC, TPO), steel structures, logistics centers, and industrial facilities.
CIGS technology offers high resistance to microcracks, and the absence of glass eliminates common mechanical damage risks associated with conventional crystalline panels. The flexible structure also enables installation on slightly curved surfaces. The modules perform efficiently in diffused light conditions and maintain stable output at higher temperatures, ensuring reliable energy production under European climate conditions.
An important part of our portfolio is the mobile and off-grid segment. NGE panels are used in trucks, trailers, motorhomes, monitoring systems, and autonomous 12V and 24V installations. Their lightweight construction and vibration resistance make them an ideal solution for transport and mobile power applications, supporting fuel savings and reduced CO₂ emissions.
We are committed to environmental responsibility. The products we offer are characterized by a low carbon footprint, high recyclability, and a European production chain. This makes them fully aligned with ESG strategies and the expectations of modern investors and developers.
Natural Green Energy is more than a product supplier – we are a technology partner. We support our clients in system selection, technical evaluation, and project implementation. Our mission is to develop lightweight, sustainable solar solutions that open new possibilities for modern architecture and the future of mobility.

BOLD Photovoltaic Panel – CIGS Technology
BOLD Photovoltaic Panel – CIGS Technology
BOLD Photovoltaic Panel – CIGS Technology
BOLD is an ultra-lightweight photovoltaic panel based on CIGS (Copper Indium Gallium Selenide) technology, designed for roofs with limited load-bearing capacity and specialized applications. Its glass-free, frameless construction eliminates the risk of microcracks, enhances mechanical durability, and ensures stable performance throughout the year.
With a weight of approx. 3 kg/m², it can be installed without reinforcing the roof structure. Installation is carried out by bonding – without drilling and without affecting the roof’s waterproofing layer. The panel operates efficiently under partial shading, in diffused light conditions, and during winter periods. Ideal for roofs, façades (BIPV), transport applications, and 12V off-grid systems.
BOLD – CIGS Thin-Film Photovoltaic Panel (BOLD 6 / BOLD 8)
BOLD is an ultra-lightweight photovoltaic panel based on CIGS (Copper Indium Gallium Selenide) technology, designed for low load-bearing roofs. Available in two variants: BOLD 6 (1.0 m width) and BOLD 8 (1.3 m width), with lengths from 1.7 to 6.0 m. Thickness is 2 ±0.5 mm and weight is 2.9 kg/m². Minimum roof pitch is 2°, minimum bending radius 0.25 m.
Nominal power: 240 W (B6) / 500 W (B8); power density: 120 / 131 W/m². VMPP: 37.4 / 75.0 V, IMPP: 6.6 A, VOC: 45.7 / 91.3 V, ISC: 7.6 A. Maximum system voltage 1000 V DC, design load ±3600 Pa, operating range –40°C to +85°C.
Bonded installation (butyl tape) – no drilling or ballast. Glass-free construction ensures microcrack resistance, walkability, and high UV durability. BROOF (t2) certified. 25-year product warranty (90% after 10 years, 80% after 25 years). 98% recyclable materials, 63% recycled content, carbon footprint approx. 6 g CO₂/kWh.
