Rudimentary. Simple. Lacking.

The app is poorly engineered and poorly executed. It is impossible to get data on individual panels and historical performance. The graphs are simple but lacking. I’ve seen zero improvement in the 9 months since installation. Zero new features.

Melhorou muito mas pode mais

Pra o que era melhorou muito mas ainda faltam recursos de concorrentes

Can’t Reset Password

This is probably one of the worst apps I’ve used. You literally can’t even reset your password on the app. It pops up with a blank error box and gives you the option to cancel or confirm.

Difícil

Na versão antiga era mais fácil verificar geração nos dias anteriores

New app

The new app is terrible. The old version was offline frequently, but much more user friendly. At some point that one just stopped showing each panel and what it was producing. Go back to the old version or perhaps go back to the drawing board and start over.
