What we do?


Detra Solar designs commercial and utility-scale solar projects for fortune 5000 companies, utilities, developers and government agencies worldwide.

Our engineers have designed over 9.4GW of renewable projects in 48 countries, gaining in-depth knowledge of the solar industry.

Solar PV Design & Engineering


Our extensive knowledge and experience in solar design and engineering on projects that span the globe, ensure that we employ the best practice methodology and industry standards specific to your project, while staying up-to-date with the latest technologies and advancements.

Our methodology, and our meticulous collaborative approach to working with our clients allow us to identify solutions to problems before they even arise, giving our customers peace of mind throughout the whole design process.

As the minds behind the creation of PVcase, the market-leading solar design software, Detra Solar’s team is able to utilize it to its fullest potential. With PVcase and a clear priority on precision and promptness, our expert engineering team brings solar projects to life at an unmatched pace and degree of accuracy. At Detra Solar, we can support any solar project at any stage, including:

  • Initial design scoping
  • Construction ready drawings
  • Planning application ready drawings
  • As-built drawings

Optimization & Consulting


With a powerful combination of PVcase and yield projection software – PVsyst, our engineering team can create and compare multiple configurations for systems with high accuracy and short time frames. By simulating various electrical setups and the distribution of frames, we often take topography into account, which is further used to foresee capacity and generation limiting factors with high precision.

A comprehensive analysis of topography also allows accurate optimization by evaluating terrain variations and matching that information with inclination tolerance levels of each frame individually. Using advanced analysis methods and running multiple iterations, we can provide feedback and suggestions on how to reduce operational losses, maximize energy output and increase profits. These services include:

  • Equipment analysis using PVsyst
  • Module technology comparison
  • Frame placement iterations
  • Layout based on optimization

Energy Production Simulation


Using our in-depth knowledge of both PVsyst and PVsol, we’re able to create simulations of any solar installation while calculating yearly energy distribution with high accuracy. Available simulations include:

  • Forecast total energy production [MWh/y] to evaluate profitability
  • CEstablish data on performance ratio (PR [%]) to define the quality of the system
  • Assess specific energy [kWh/kWp] data to indicate system’s energy production
  • Create 3D shading scenes to provide an in-depth shading effect analysis

Project Visualization


One of the most efficient ways of moving your solar project a step closer to implementation is using visualized drawings. Making your solar project visually appealing and clearly showing the impact it has on the local environment has been a very successful factor in getting planning permissions for many of Detra’s clients. Whether it’s a large-scale project with a scenic area or a simple design, we can make it significantly more appealing using the following:

  • Rendered photo-realistic images
  • Photo-montages on existing images
  • Rendered fly-through animations
  • SketchUp based visualizations
