How do you think of PV Power Optimizer? Do you think if it is necessary to install? what is its market prospect?
We have been planning to research a power Optmizer to improve the efficient of Panels with MPPT function since last year. We found that some company have already launched this production, though we still want to research it by ourself.

So how do you think of it, do you think if it is necessary to install an optimzer for each module, how do you think of its future market? what is your most concern? What's other function do you want it has?
