Solera Technologies

At the heart of every high-performing solar panel lies a component that quietly does the heavy lifting. Solera’s TRIO SPLIT Solar Junction Box is engineered to ensure safe, stable, and efficient power transmission, even under the most demanding operating conditions.

With a robust design, advanced insulation, and high resistance to heat, dust, and moisture, the TRIO SPLIT minimises power losses while enhancing long-term module reliability. Its compact, installer-friendly structure makes it a trusted choice for modern solar applications where performance cannot be compromised.

PV Junction Boxes play a very important role in ensuring the service life of solar photovoltaic modules to meet the 25-year promise. Despite their small and compact design, Solera Junction Boxes are among the most crucial components for reliability. Our product steals the show with its compact and robust design, ensuring minimal leakage currents and increased efficiency while accommodating the latest technology demands. The integrated module diode ensures thermal stability under high-voltage conditions.

Solera Junction Boxes come with an integrated module diode, providing superior heat dissipation and maintaining a controlled junction temperature. The premium-grade plastic material used for the enclosure has thermal endurance of up to 125°C, a flame class of 5VA, and an ingress protection rating of IP68, making the product more robust for harsh conditions and superior to any similar product in the market.

At Solera Technologies, we are leading the way in technological advancements in the industry. We have recently implemented cutting-edge technology in our Junction Boxes, achieving superior efficiency. To enhance our testing capabilities, we have expanded our heat testing chamber and dust testing chamber to ensure our commitment to quality and innovation.

From the start, the quality of the product has always spoken in favour of the organisation, driving us forward to become the most preferred and reliable choice among clients. Solera promises high reliability and unrivalled customer-oriented service.

We continuously upgrade our product range and offer solutions. These solutions also increase system performance. In the production line, we have greatly benefited from relying on our core technologies and high-quality manufacturing processes, improving product performance, conversion efficiency, and product reliability while reducing technology-related costs.

The module industry is adapting new technology on a daily basis, and we do the same at Solera. Keeping ourselves one step ahead, we have introduced 30A and 35A JB for high-watt-peak bifacial modules, ensuring that our customers get a one-stop solution for Junction Boxes.
