Pv panels location, ground level behind house.

A roof is a free mounting system already there. For a large array, throw in a few hundred quid in parts (plus the PV panels) and you're done. The same system as a ground mount would cost a few thousand in materials alone (plus the PV panels).

Not saying you shouldn't do it, if your roof isn't feasible or not enough and you have the land, by all means go for it. Make sure you do your sums though, it will take a lot longer to pay for itself particularly if you don't fully DIY it. Possibly twice as long.

You posted a similar picture before Lar and have to say, still impressed with that.

One thing I noticed though is that you might have some shading (at least in the picture there) on a few panels. This will probably go away when the months progress in the year, but have you considered or found the need for optimizers?

@irishchris did a DIY job and has photos up somewhere on the forum.

My recommendation is to forget the "tracking" and just go for a 1-axis adjustable "tilt".

Why? Because it's simply not worth the complexity for the gains that 2x axis gives you.

Solar Trackers: What You Need to Know | EnergySage

Specifically.....

The biggest benefit of a solar tracking system is that it offers a boost in electricity production. Generally, a solar panel system with a single-axis solar tracker installed sees a performance gain of 25 to 35 percent. A dual-axis tracker bumps performance up by another five to 10 percent.

It's a return on investment thing. The complexity is higher with the gimbals, the equipment is more costly. It's easy enough to do something with some angle iron and make an adjustable 1x mount with (say) 3 settings. Winter, Spring/Autumn and Summer. This will give you a nice boost in generation for relatively easy investment and maintenance. You manually change the settings every 3 months and your done. If you really want the an extra 10%, just add on an extra panel €150 to your array and your done! (11 panels instead of 10 etc)

Just completed final array this week on new ground mount. A further 2.6kwp and should be the final one bringing my arrays in total up to 10kwp.

Unfortunately didn't take any photos when doing it other than this one when finished but it is similar design just done a bit tidier and more efficiently as the original install which I put photos up in recent thread.

The new array is the furthest one in this photo and is 380w x 7 panels. This is one string and the other string on this inverter is the existing 12 X 360w panels.

Also then have the SAAS 2.88 on the roof.

The ground mounted array made a tidy 27kwh today considering it was a shower filled day. Now the fun part of kerbing them off and stoning the area begins.

Thanks for the link.

@irishchris nice set up. I like the idea of slightly different angles on the arrays. I'm going to have to build it into my design.

Where did you get the kit?

Seems to be a, shadow at the end of the first array.

Did you have to set up a way to limit export?

Is that a solis? Can I ask where you got the CT for it?

I bought the K2 brackets for roof mounting, they had an 8mm hole for the bolts, drilled that out and used 120mm M10 Stainless Steel coach screws, bit of overkill perhaps but its done now.
