Solar Panels Not Producing
When a system underperforms, output drops below what the panels should produce.
Cell Efficiency Losses From High Heat
Phoenix arrays lose output on hot summer afternoons as cell temperatures rise.
Flush-Mount Restrictions on Bifacial Arrays
Installing bifacial panels flush against a roof blocks airflow and rear-side reflection, eliminating potential 10%-30% power gains.
Soiling From Dust and Pollen
Dirt, dust and pollen cut light transmission on Phoenix arrays.
Bird Droppings and Hotspot Precursors
Bird droppings create severe thermal hotspots in individual cells and fire risks that string-level monitoring misses.
Cell Micro-Cracking
Thermal cycling and physical stress crack silicon wafers and cut output over time.
Inverter Thermal Overheating
Phoenix heat causes inverter thermal derating and early failures.
Inverter Power Clipping
Array-to-inverter mismatch clips solar power in Phoenix.
Battery Capacity Decay Over Cycles
Solar batteries lose capacity over cycles, and Phoenix heat accelerates the decay.
Reduced Value Under Net Billing
Net billing cut what exported solar is worth in Phoenix.
Inverter and Distribution Grid Voltage Rise
High rooftop solar density raises voltage on Phoenix feeders and trips inverters at midday.
Free Government Solar
Ads promising 100% free government solar in Phoenix are lead-generation bait, not a program.
Pressure Sales Tactics
High-pressure solar sales rely on artificial deadlines, fake discounts and rushed tablet signatures.
Unnecessary Roof Replacement
When an installer insists a sound Phoenix roof must be replaced before solar, the recommendation is usually about the invoice.
Hidden Loan Dealer Fees
Solar loans advertising low rates often hide 15% to 30%+ dealer fees inside the financed amount.
Lease and PPA Escalators
Leases and PPAs keep the tax credits with the third-party owner and often carry 1% to 3% annual escalators.
Unvetted Subcontractors
The company selling you solar may never send an employee to your roof.
Orphaned Warranties
When a Phoenix solar installer closes, workmanship and labour warranty claims have nowhere to go.
