Concept Design Level Projects
One of our core strengths lies in our ability to develop comprehensive concept designs for large-scale solar projects. To date, we have successfully designed over 3GW of solar energy capacity at the concept design level. Our approach to concept design is rooted in a thorough analysis of site conditions, environmental impact assessments, and advanced modeling techniques. By integrating cutting-edge technology and best practices, we create designs that maximize energy output, optimize land use, and ensure long-term sustainability.
Our concept design services include:
Parcel Selection Analysis
Including yield generation comparison.
Conceptual PV & BESS Layout
With main equipment included. Co-located battery storage (BESS) on request.
Single Line Diagram
PV and PV + BESS grid connection options (LV and MV).
Construction Design and Ready-to-Build Projects
In addition to our expertise in concept design, we excel in preparing detailed construction designs for ready-to-build solar projects. Our team has meticulously engineered and prepared over 300MW of solar projects for construction, ensuring they meet the highest standards of quality, reliability, and safety.
Our construction design services encompass:
Detailed Engineering
Creating precise and comprehensive engineering drawings and specifications for PV and battery storage (BESS) sites that guide the construction process.
Permitting and Regulatory Compliance
Navigating the complex landscape of permitting and regulatory requirements to ensure projects are compliant with local, state, and federal regulations.
Procurement Support
Assisting with the selection and procurement of high-quality materials and equipment to ensure project success.
Construction Management
Providing on-site management and supervision to ensure projects are completed on time, within budget, and to the highest quality standards.
Fixed-price design packages
Most of our work is sold as a package with a fixed scope, a fixed turnaround and a fixed price agreed before we start. Send us the site or the drawing set and you get a quote within 24 hours.
| Package | What you get | Turnaround |
|---|---|---|
| Site check | Indicative layout, realistic MWp and MWh, grid options, the three constraints most likely to cost money later | 5 working days |
| Concept design | Optimised PV and BESS layout, single line diagram, yield estimate, equipment list for tendering | 10 working days |
| Independent design review | Second read of an existing layout or SLD: clashes, over-specified items, anything likely to become a change order on site. NDA first if needed | 5 working days |
| Construction design | Detailed engineering package in your templates and standards, ready for tender and build | Scoped per project |
| BESS add-on | Co-located or standalone storage added to any package above | +5 working days |
Technical partner for investors and developers in the Baltics
Investors entering Lithuania, Latvia and Estonia rarely have a local engineering team. We act as that team on a monthly basis: site and portfolio screening, grid connection analysis with Litgrid, ESO, AST and Elering, permitting and subsidy roadmap, concept design, EPC and equipment tender support, construction supervision. One monthly fee, one point of contact, a one-page status report every two weeks. We work with no more than five retained clients at a time.
First step: send us one site or one project. Within 10 working days you get a written screening with our recommendation, free of charge.

Testimonials
We choose to keep our customers confidential
Our internal team was overworked so we partnered with Solid Solar for the full construction-ready design package support for 68Mw Ground mount project, and we couldn't be more satisfied. Their team provided detailed, high-quality designs that met all regulatory requirements for UK and set the stage for a smooth construction phase. Solid Solar’s dedication to excellence and precision truly sets them apart.
Solid Solar played a crucial role in the successful planning of over 500Mw portfolio in 2023. Their ability to create comprehensive, forward-thinking designs at planning pahse ensured that every aspect of the project was meticulously planned and executed to achieve construction permit. Their commitment to delivering top-notch service and support throughout the process was exceptional.
Biggest respect to team Solid Solar for taking over a design project in the middle of the project as our team could not find proper design engineering solutions to fit the required DC capacity and deliver project up to Investor requirements.
