A Reddit DIYer says a simple switch made a clear difference for a four-panel solar array at a shop. The quick change was so successful that it prompted plans for a more permanent roof mount.
Here's what to know
In a Reddit post, the original poster shared before-and-after photos of their setup's output and credited the move from the west wall to the south wall.
"I have a four panel array that I lazily set up this summer using Obama era panels and some plug-ins," they wrote. "I decided to invest a bit of time into moving them and damn, still a very temporary B game install but damn, huge improvement."
Several Redditors suggested the seasonal timing was part of the improvement. One commenter wrote, "Sun is getting lower every day! Good move!" as a reminder that panel direction becomes more important through winter.
For homeowners considering a more permanent setup, going solar is one of the best ways to save on home energy, and solar leases in particular can deliver hundreds of dollars in monthly savings with no upfront costs.

More background
Rather than putting the system on a roof rack or a ground mount, the DIYer simply shifted the panels to a different exterior wall. For people working with older equipment and tight budgets, that kind of low-cost change can be especially appealing.
The conversation also turned toward seasonal panel setup. One commenter pointed to two winter-specific advantages of the south-facing position: "With the sun this low, south facing makes a big difference through winter. If you can tilt them steeper for the cold months you'll get a bit more again, and snow slides off easier." From there, the discussion focused on orientation and tilt.
The original poster didn't share a dollar amount, but getting more production from the same four panels can extend the value of a modest system without buying new hardware. For people piecing together plug-in solar projects, that performance boost may matter as much as adding another panel.

What can be done?
Trying a different location before committing to a permanent mount can be a smart move.
"They're just leaning against the wall to my shop, works great!" the user shared. "I'm reconsidering mounting them on the roof honestly but I know that'll be way better come spring."
The roof may still be the long-term plan, but the original poster suggested waiting for the right time.
