Looking at a large solar farm and wondered if anyone had experience doing these? Trying to figure out which is the safest / best / fastest / safest (yeah, I said it twice - its a glass house, kinda) way to approach this thing.

The panels are only about 16-20" off the (sometimes uneven) ground and we have to get back about 3' or so under them. The rows are about 8-10' wide and at least 100 yards long.

The dilemma: How to mow under (the low side), between (down the middle) and under the high side, without throwing a rock or breaking the panels, efficiently. They are at a fixed 30 degree angle. Like I sad, 16+" on the low side and 6' or so on the high side.

I have a batwing, but there is no way it's going to fit under the low side. One small bump and there goes a few hundred dollar panel.

Also, Round up isn't an option.

Thoughts?

Man.....talk about the possibilities for some bad luck! Too many mirrors for me! :)

I wanted to recommend using a flail mower, but I think that'd be more hazardous than anything. We just had a solar farm built on the north end of town within the last month. Rather curious to see how they maintain that area. I know which LCO is handling it, but I haven't seen them mowing through there yet.

Round up isn't an option? You seriously need to sell the property owner on putting gravel with a nice border (edge) or something in underneath these panels to minimize the maintenance. Inform him/her of the dilemma with the danger of the panels being so close to the ground, the reduced long-term maintenance costs, and the aesthetic improvement in general.

Maybe it's the 4th cup of coffee talking, but I'm making myself laugh as I imagine that that the solar panels are used solely as a power source for thousands of cheap, plastic landscaping lights that have their cables buried 1" below the surface, creating what could arguably be considered the toughest lawn servicing bid known to man.

How about using PGR's in some of the hard to cut areas? Do you have any picture of what this looks like? Is it full grass or a field with weeds? Fertilized or not? Expectations from the property owner? Dimensions? Acreage? Google Map?
Sounds interesting and if the money is right I would figure something out.

I was thinking the same thing about the boom flail. Is there a company that makes a bush hog with a boom? Or how about one of those tow behind mowers that are offset to one side? If all else fails and you are making a good profit, just give a couple guys some knee pads and garden shears.

I am sorry but I would be all for convincing this customer that a layer of mulch over top of some weed control fabric would be the way to go because the risk of damage and the liability being so great you really want an area that is as relatively maintenance (and machine) free as possible, before mentioning any of it I would have a price already in mind so I can give them that as well and be prepared that it may not be the answer they want...

But...
And we take on all KINDS of work!
But this is one I wouldn't want to play with.

Lots of good input, but I don't think we have a winner yet. This is close to 100 acres and mulching is not an option. I have included a pic for everyone to get a better idea of what I'm talking about.

Like I said, there is only about 16" to 20" (max) of clearance at the lowest point of the fixed angle panel and I need to get back under the panel about 3 feet or so. I haven't found a rotary mower with that kind of clearance, height wise. Not to mention that the soil is not perfectly level and any little bump could throw it up into the panel.

The only thing that I have been able to come up with is a sickle bar mower (very old school) on the back of a tractor and a rear discharge belly mower underneath. This would allow one pass and cover most of the area.

Down the middle is the easy part. It's getting under the panels, especially the lower side, that's tricky. Not to mention the wires that connect each panel to the next. You can see them if you look closely. They are dangling just enough to be a pain.

Take a look at the pic and see if you can suggest something else that may work.

The problem with a rear discharge mower is that the discharge doesn't just come straight out the rear of the deck...it comes out at a lot of different angles.

Mow the middles with a rear discharge zero turn, get the rest with roundup and soil sterilant. That's the only feasible way I would see to do it.

What about a sickle bar mowers like that. The only problem is it leaves it whole an doesnt mulch it.

If it was me I would go in with a skid steer mounted offset sickle bar then do the center with a flail mower. I know brushhound makes a good flail that doesnt kick much up its got alot of guarding on it witch is nice.

have 1 guy on a stand on or wb to do under everything and one guy on the z-turn or other stand on to do the rest.. or just cit sprinkler lines so the grass dries up and dump roundup all over the place

100 acres of that! Looks like the solar farm just needs to put a person or 2 on payroll to maintain that! Unless they got the money to pay (make it profitable) for a LCO. To much of an obstacle course. Does look like alot of liability there for LCO!

somewhere on the internet (i can't find it) there is a video of a very powerful) walk behind tractor that has a sickel mower attachment on it. this guy was cutting hay with probably a 15' bar and was just flying. it is blue and has metal wheels, I actually saw the units at GIE expo but can't remember the name. this would be a great spot for one of those

Good call! I believe the brand on those is BCS.
