OpenSolar Partner UK – Power Solar Projects with Alternergy

We’re excited to announce that Alternergy is now an official partner of OpenSolar, one of the most powerful and widely used solar design software platforms for installers in the UK.

At Alternergy, our focus is to support installers not only with high-quality products but with the tools and systems needed to design, quote, and deliver projects efficiently. As the solar market continues to grow, having the right combination of PV design tools and reliable solar product supply is essential to delivering projects on time and to specification.

This collaboration helps UK installers and EPCs better connect solar system design and management with reliable product supply, supporting more accurate proposals, smoother project delivery, and fewer last-minute changes.

By aligning OpenSolar’s design, sales and management tools with Alternergy’s trusted range of solar panels, inverters, battery storage, and mounting systems, we’re helping installers save time, reduce complexity, and deliver projects with greater confidence.

What This Means for Installers

• Live Alternergy pricing, availability and product data in OpenSolar
• Build proposals that match exactly what you’ll order
• Reduced duplication and fewer design-to-quote mismatches
• Fewer redesigns and smoother installations
• A faster, clearer workflow from initial design through to delivery

OpenSolar offers a wide range of product options to support system design and comparison, giving installers flexibility when planning projects.

If customers want to explore additional options or refine a system further, the Alternergy team can help. Alongside the products available within OpenSolar, we can support with a broader range of components and system configurations from our wider portfolio.

Our team works closely with installers to align system designs with available stock, suggest suitable alternatives where required, and ensure that every project is practical, deliverable, and cost-effective.

Working with Alternergy ensures your design can be translated smoothly into a real-world installation, with access to a reliable supply chain and expert support throughout the process.
