MPPT at each solar panel
 
At the 2011 Midwest Renewable Energy Fair I saw for the first time a Maximum power point tracking (MPPT) that fit to the back of each solar panel, I've seen the MPPT that my parents have on their array boost the output above the labeled rated output many times along with allowing them to run a higher voltage wiring saving the cost of wire and the cost of extra panels to cover the losses, it all works quite well! so I was excited to see their solar panels on the EV charging station car port using this brand new MPPT device, I was told that the cost is about the same as having a central inverter but that install is a little extra because of the multiple devices that get wired in thing is the end output apparently is at or above the rated output of the panels while outperforming a central MPPT with an inverter next to it.

do you recall any of the product information so that we may google it on the internet?

Sorry, I forgot to link to them.

Solaredge is the one that I saw and I think they are the first ones out with a product like this but I was told that in 6 months to a year the price will either drop or they will come out with a new model, I'm broke right now because of a new water heater and other house projects but in a year I should have enough saved up to do a solar awning as that would keep my house cooler in the summer and be the cheapest way to mount them, cheaper then ground or roof mounts.

I'm in the middle of a pseudo-solar awning for my storage shed. It sits on an asphalt pad, and the sun's heat just gets bounced back onto the south wall for extra heat. After using temporary tarps to shade the south wall, I've come to the conclusion that I need something which doesn't impede air flow as much as a solid sheet, so I'm looking for enough camouflage netting to cover the same area. I can buy huge tarps, but not huge netting, These I've got to piece together. So far I've found poles and spreaders locally, but the netting is scarce.
