Avoid costly errors and wasted investment — I share the 10 biggest mistakes I’ve seen (and made) when installing solar panels, plus how to plan smarter for a more efficient and future-proof system.
If you’re planning to install solar panels, take it from someone who’s been there — it pays to do your homework. I’ve spent years experimenting with solar setups, from rooftop arrays to a full-fledged solar carport. Along the way, I’ve made (and witnessed) just about every mistake possible.
In this blog post, I’ll walk you through 10 crucial pitfalls to avoid — so you don’t waste thousands of dollars or end up with a system that underperforms.
One of the most common rookie errors I see is sizing your system based on a single month’s utility bill. That’s a huge mistake.
Solar isn’t cheap, so proper planning makes or breaks the return on your investment.
Early on, I skipped batteries to save money — and regretted it the first time the power went out.
If energy independence is your goal, make room in your budget for batteries upfront.
If someone offers you free solar, run.
Solar is an investment, not a giveaway. Transparency matters.
Your solar system is only as good as the roof it’s installed on.
Fixing a roof post-installation is expensive and risky. Get it inspected first.
Skipping permits is a shortcut to disaster.
I once built a solar wall only to learn it couldn’t be permitted in my area. Don’t be me — check before you build.
Cheap gear may seem appealing until something breaks.
Quality pays for itself in peace of mind and system longevity.
Installation quotes can be all over the map. Trust me, I’ve seen them range from $18K to $80K.
You don’t want to overpay for the same result.
Solar isn’t a “set it and forget it” system.
Performance tracking equals savings and longevity.
Your energy needs will grow — plan for it now.
Think long-term. Your future self will thank you.
Local knowledge can make or break your solar journey.
Avoid out-of-town sales reps pushing cookie-cutter solutions. Go local and get it done right.
Solar power can be life-changing — but only when done right. From estimating energy use to choosing the right hardware and installer, every decision matters. I hope this guide helps you avoid the most common solar installation mistakes I’ve seen (and made). Be informed, be critical, and don’t rush. Your solar system is a long-term asset — make it one you’re proud of.
