Services
We design, supply equipment, and build solar plants turnkey.
Solar Plant Design
We develop the technical foundation on which the entire plant is built.
Site Analysis
On-site specialist visit: topographic survey, insolation level assessment, shading analysis from buildings and vegetation, surface orientation and tilt angle. Based on the data, the optimal plant configuration and location are determined.
Generation Calculation
Computer modelling in PVSyst and PVWatts: annual electricity output forecast, capacity utilisation factor (CUF) calculation, loss analysis and payback period assessment. The client receives a detailed 25-year projection report.
Equipment Selection
Comparative analysis and selection of photovoltaic modules, inverters, mounting systems and cable products for the specific facility requirements. We consider climatic conditions, budget and warranty requirements, and work with leading global manufacturers.
Project Documentation
Full set of design and working documentation: schematic and installation electrical diagrams, equipment layout plans, cable schedules, foundation and structural drawings. Documentation is developed in accordance with current standards and regulations.
Approvals & Grid Connection
Preparation and submission of applications for technical conditions, coordination with the grid operator at all approval stages. We ensure all permits are obtained and manage the grid connection procedure on a turnkey basis.
Cost Estimation
Detailed cost breakdown by line item: equipment, materials, installation and commissioning works. Bill of quantities, material specification, financial model with ROI and payback period calculations.

PPA — Solar Energy With Zero Investment
We build the plant at our own cost — you simply buy electricity at a lower rate.
Design
Site analysis, consumption and generation calculations, optimal solution selection. All technical work is performed by BTT.
Supply & Construction
BTT finances and implements the full cycle: equipment supply, construction and installation at the client's facility.
Launch & Operation
Commissioning, connection, monitoring and maintenance throughout the contract period — without client involvement.
Energy Sales
The client receives electricity at a fixed below-market rate for 25 years. Zero capital investment, predictable costs, savings from day one.
