ā”Key Themes
š¹ The Best System Isnāt the BiggestāItās the Smartest Fit
Hereās where things almost went sideways:
š§ Ignored shading ā No microinverters = major performance loss
š Maxed out system size ā Left no room for EV or future load growth
š Mismatched load profile ā Peak usage at night, no battery = lost savings
š Misunderstood warranties ā ā25-yearā promise wasnāt for hardware
š Trusted a generic quote ā No site-specific design = roof mismatch
š” Lesson? The numbers only matter if they match your actual home and habits.
š¹ 5 Smart Moves That Could Save You Thousands
ā
Ask how shading is managed ā Microinverters or optimizers might be essential
ā
Plan for the future ā Design with future appliances, EVs, or growth in mind
ā
Get a load profile match ā Use your utility data to align production + usage
ā
Read both warranties ā Know the difference between performance vs. product
ā
Demand a roof-specific design ā Not just a spreadsheetāan actual model
ā”Discussion Questions
š¬ Have you used an instant solar calculator?
How much did it reflect your actual roof and energy usage?
š¬ Did your installer explain inverter optionsāor just pick one?
š¬ What surprised you most in your solar research?
š¬ Would you feel more confident with a third-party design review before signing?
ā”Action Steps for Smarter Solar Buying
ā
Check your roofās sun accessāuse a solar assessment tool or get a pro shading analysis
ā
Review your last 12 months of energy usage to size the system properly
ā
Ask your utility about net metering rules and TOU rates
ā
Request quotes that show system layout, shading impact, and future add-ons
ā
Confirm whatās included: module-level optimization, monitoring, warranties, and upgrades
ā
Always ask: Does this system fit my actual roof, my future usage, and my goals?
ā”Reflection
Solar isnāt just about chasing the best specs or the cheapest quote.
Itās about precisionādesigning a system that fits your roof, your lifestyle, and your future.
This near-miss didnāt end in regretāit ended in clarity.
Now, the author knows what questions to ask.
And soon? They'll go solar smartānot solar sorry.
