PVinsights:Upstream in Deadlock

Polysilicon prices remain stable this week since the strength of the current solid demand is still not strong enough to enhance price further. Moreover, as the expectations of the possible severe downturn in June, polysilicon suppliers prefer to hold the prices in order to secure more orders in the coming month, instead of raising prices. On the other hand, the prices outside China remain stable as well, pressured by ample supply and demand doubt.

Introducing RockIt Smart Slide

Introducing RockIt Smart Slide

Introducing RockIt Smart Slide - the ultimate solution for fast and easy installation of the rail-less RockIt racking system on composition shingle roofs. Smart Slide conforms to UL 441 and TAS 100 (A)-95 for wind and wind-driven rain, providing a super-strong watertight seal that is achieved through compression, in most cases without the need for additional sealant. The waterproofing sealant is embedded deep into the granules of the shingle, thanks to the integrated flexible foam layer that provides cushioning. This ensures a secure fit that conforms to any architectural-style shingle. With UltraGrip Technology™, you can rely on a secure installation, as it absorbs the movement created by thermal expansion and contraction. The pre-installed sealing pads are compatible with all composition shingle roofs, making it the ideal choice, even in ambient temperatures as low as 5 degrees.
