Solar energy
Part of the Energy & Raw Materials sector
Solar energy covers converting sunlight into electricity or heat, along with the panels, inverters, mounting systems and the installers and EPC companies behind each project. This hub explains the main technologies and how to find and compare verified solar companies on Digibition.

Overview
Solar energy splits into two main families. Photovoltaic (PV) systems use semiconductor modules to turn light directly into electricity, paired with inverters, mounting structures, cabling and increasingly battery storage. Solar thermal systems instead capture heat, for hot water, process heat or, at larger scale, concentrated solar power.
PV is the most widely sourced on a B2B directory. A typical project combines products — modules, inverters, mounting systems, optimisers and storage — with services such as design, permitting, installation and ongoing operations and maintenance. Suppliers may specialise in one layer or deliver the whole system.
On Digibition, module and inverter manufacturers, component suppliers and solar installers or EPC companies publish verified profiles, so buyers, developers and asset owners can discover and compare them by specialization and country. This is general information, not legal, technical, or regulatory advice.
What to check when sourcing
For solar hardware, read the datasheet carefully: rated power, efficiency, temperature behaviour, and warranty terms for both the product and its performance. Confirm certification to recognised standards and ask how long the manufacturer has supplied the product and whether spares and support are available over its service life.
For installation and EPC services, check the provider’s licences, grid-connection experience and references on comparable projects, and clarify who handles permitting and grid code compliance. Be cautious with output or savings figures — real generation depends on location, orientation, shading and weather, so ask how any estimate was produced rather than treating it as a promise.
Use the directory to shortlist companies by specialization and country, then contact several and compare their scope, credentials and responses before you commit.
What to check when sourcing solar energy
| Criterion | What to look for |
|---|---|
| Technology | PV or solar thermal, and the specific products you need |
| Datasheet | Rated power, efficiency, temperature behaviour and tolerances |
| Warranty | Separate product and performance warranties, clearly stated |
| Certification | Compliance with recognised module, inverter and safety standards |
| Installer credentials | Licences, grid-connection experience and project references |
| Service scope | Design, supply, install and operations-and-maintenance coverage |
Frequently asked questions
- What is the difference between PV and solar thermal?
- Photovoltaic (PV) systems turn sunlight directly into electricity using semiconductor modules and inverters. Solar thermal systems capture heat instead — for hot water, process heat or concentrated solar power. The two use different equipment.
- What products make up a solar PV system?
- Typically modules, inverters, mounting structures, cabling and protection, and often battery storage and monitoring. A single supplier may provide some or all of these, or a project company may assemble them from several sources.
- How do I find solar suppliers and installers?
- Use the Digibition directory to filter by this specialization and by country, then open each company profile to review its products, services, certifications and specializations. You can message companies directly, or add several to a quote list and request quotes from all of them at once.
- How should I treat output or savings estimates?
- With caution. Real generation depends on location, orientation, shading and weather, so ask how any estimate was produced and under what assumptions rather than treating it as a guarantee. This is general information, not legal, technical, or regulatory advice.
- What should I verify before buying?
- Confirm the datasheet specifications and warranty terms, the certifications your market requires, and the installer’s licences and references. Clarify permitting and grid-code responsibilities, and compare several offers before committing.
