We only remain stubborn when it comes to quality. Whatever leaves our production halls has been proved and always complies with the highest international required standards. These are only changed if it’s for the good of quality. Then and only then can we guarantee you long durability.

Shading Resistant Smart Modules with Hot-Spot free technology

Power Range: 5W-680W

Available in mono and polycrystalline

- Supreme design and quality.

- Individual bypass diode for each cell. With Hot-Spot Free technology protects each cell by an individual bypass diode.

- When the current of a single cell does not match the current of the whole string, that cell has a reverse voltage, so when measured more than 0.6V, it will automatically activate the bypass diode. As a result, the rest of the cells will not be affected by the disruption.

- Increased performance ratio up to 30%.

- We provide all international standards' certificates, 30 years performance guarantee and 12 years product warranty.

With a large selection of module dimensions and performance classes you will find exactly the right one for your project
