Introduction & Mission

Introduction

Welcome to BST.SOLAR — your trusted partner in advanced renewable energy solutions.

We provide high-quality solar and energy storage products, combined with professional engineering and control system expertise, across Europe. Beyond standard installations, we specialize in tailor-made, fully controlled energy systems designed to meet the exact technical, operational, and regulatory requirements of each project.

We are ComAp Experts, with deep experience in controlling and integrating diverse energy assets into reliable, intelligent systems.

What We Do Best

At BST.SOLAR, we go far beyond equipment supply. Our core strength lies in system-level control and optimization:

  • Design and implementation of custom-controlled BESS installations
  • Zero feed-in protection and grid-compliant control logic
  • Installation of energy audit-ready measurement and monitoring systems compliant with ISO 50.001

Intelligent control of multiple energy sources, including:

  • Solar PV systems
  • Battery Energy Storage Systems (BESS)
  • Diesel and gas generators
  • Grid-connected and island-mode microgrids

In short: we know how to control complex energy systems reliably and efficiently.

Our Mission

Our mission is to empower our partners with sustainable, innovative, and dependable energy systems that:

  • Reduce long-term operational and energy costs
  • Increase energy independence and system resilience
  • Comply with local grid codes and regulatory frameworks
  • Are ready for future market services and flexibility opportunities

We believe that the future of energy is not only about generation — it is about intelligent control.

about us

About Bright Sustainable Technology (BST)

At BST.SOLAR, we build on a strong foundation of hands-on experience and technical expertise in the renewable energy sector.

Our journey started with Genezis Electronics, delivering solutions across green energy, engineering, and system integration. Over the years, we developed and operate our own PV power plants, later expanding them with aFRR-capable power plants, gaining real operational insight into modern energy systems.

Through our Operation & Maintenance (O&M) activities, our team evolved into a group of professionals who deeply understand the systems we design, install, and supply. This is why we work exclusively with proven, high-quality technologies from leading manufacturers such as CATL, EVE Energy, SERMATEC, SUNNIC, DELTA, KEHUA, SINEXCEL, Huawei, and ComAp.

Today, we combine engineering, control systems, and operational know-how to deliver advanced, integrated energy solutions for a rapidly evolving energy market.

Advanced storage, control, and conversion technologies from trusted manufacturers.
