How about a solar car port on a budget?

[Crossy]

The car port is really, really full now.

 

At least until ...

So, we have a total of 28.8kWp spread over the three areas.

 

I've still got 2 x 540W and 1 x 340W panels spare.

 

Where to get them in ...

How's about making it a double decker ...........

That a lot of unused energy, imagine if you could use all of that all of the day.. 

Are you planning to open an EV charging station for the neighborhood? 😉

Would be good but don't forget that the amount of energy Crossy's potentially harvesting is not constant all day. The power output is quoted as 28.8kWp which only happens when the suns light  is perpendicular to the panels. But by any standards that's a lot of power.

Do you think it might might be a world record?

What is the highest Voc voltage on any of your strings?

Do you keep the Vmp right under the 425 max?

I compared his April numbers to mine and I had 1500KWh from solar and  55KWh from PEA. My panels output are half of his ie 14.4KWp and my batteries are fullly charged just after midday. I don't know what to do with the sunshine in the afternoon, guess I have to get an EV soon..😃

I tell ya, the guy is a living power plant..

Panels are 340W, Voc = 46.3V, Vmp = 38.7V

 

Longest strings (2) are 10 panels so Voc = 463V, inverter spec. is 500V max. In reality they never get anywhere near that even on a "cool" morning.

Vmp of these strings is 387V, the MPPT range is 150-425 (max power is 300-425), but once again they tend to run well below that.

 

Snapshot just now, nowhere near max power generation this late in the day, trees and house get in the way 😞
