This is normal winter performance. Depending on the location of your modules, snow can build up heavier on modules which are near a roof valley and take longer to clear than the modules on the top and sides of your roof.
If you are sure that your system is free of snow and you still are not seeing any production, please email us at serviceyyc@livezeno.com for Calgary andย serviceyeg@livezeno.com for Edmonton so we can investigate the issues further.
