A homeowner planning a DIY solar setup sparked a useful debate after laying out a careful, low-cost way to test three possible panel locations before committing to a full installation.
In a Reddit thread in r/SolarDIY, the poster said they were considering a trial run: putting one panel in each possible location and tracking the results for a few months before deciding how large the full system should be.
Here's what to know
Because meeting the home's current electric demand may require panels across "three locations (two roof pitches, one ground)," the poster said it was not easy to estimate the eventual array size. With each area offering different tilt and sky access, they wanted production data from the actual sites before making a larger purchase.
To get that information, they planned to buy three panels and spread them across the possible mounting spots for monitoring.
"This should give me some good insights into the production of each location and let me plan out the size of my array accordingly," they wrote.
Not everyone thought the experiment was necessary.
"Just buy all the panels you can fit/afford, they are cheap, stop being an optimizer (often called a maximizer), one who seeks the absolute best possible choice by analyzing every option, instead be a satisficer, one who chooses the first option that meets their threshold of 'good enough,'" one commenter wrote.
Other replies suggested outside mapping tools and installer-grade modeling instead.

"Have you checked projectsunroof for your address?" one commenter asked. "My output varies wildly by month and season."

More background
When that suggestion came up, the poster replied that projectsunroof was "a bit out of date" for their property because landscaping changes had improved roof exposure and opened more ground space. Solar estimates can shift when shade patterns change, trees come down, or site conditions change.
A small test like the one they described can reveal whether a section of roof that looks promising on paper consistently produces less power in daily use, potentially helping someone avoid overspending on a layout that underdelivers in practice.

Adding battery storage to a solar setup is one of the best ways to protect your home during outages, save money on energy, and go off-grid. It can also let homeowners store extra electricity for later instead of relying entirely on live production.
