Solar system cost isn’t just about the panels themselves — labor, permitting, financing, and profit margin all add up to the total price homeowners see on a quote. Panels now represent only about 15-22% of total installed cost, with “soft costs” like labor and permitting making up the majority of what you pay.
Cost Breakdown
| Cost Component | Approximate Share of Total |
|---|---|
| Panels/modules | 15-22% |
| Inverter and electrical equipment | 10-15% |
| Racking/mounting hardware | 5-10% |
| Labor/installation | 15-25% |
| Permitting, design, overhead, profit | Remaining balance (often largest single share) |
Labor Costs
Skilled solar installation labor has become more expensive as wages have risen industry-wide, and this labor cost is now one of the largest components of total system price — unlike panel hardware, labor costs don’t benefit from the same manufacturing scale efficiencies.
Soft Costs: Permitting, Design, and Sales
“Soft costs” — permitting fees, system design/engineering, sales and marketing, customer acquisition, and company overhead — collectively represent a substantial share of total installed cost and have proven more resistant to decline than panel hardware prices over time.
Tariffs and Trade Policy
Tariffs on imported panels and components can add meaningfully to hardware cost independent of manufacturing efficiency — trade policy has been a significant, somewhat unpredictable factor in overall solar pricing in recent years.
The Expired Homeowner Tax Credit’s Effect on Net Cost
With Section 25D expired for homeowners as of December 31, 2025, the effective net cost of solar has increased for buyers who previously would have received a 30% credit — this change, rather than any hardware price increase, is a major reason solar can feel “more expensive” than it did in recent years.
Why Panels Alone Aren’t the Full Story
Understanding that panels represent a minority share of total cost helps explain why installed solar prices haven’t fallen as dramatically as headline panel price declines might suggest — labor, soft costs, and policy changes now drive pricing trends more than panel manufacturing costs alone.

Frequently Asked Questions
Why are solar panels so expensive?
Total cost includes labor, permitting, design, and overhead, not just panel hardware, which represents only 15-22% of the total.
What percentage of solar cost is the panels themselves?
Only about 15-22% — the majority of cost comes from labor and soft costs.
Why hasn’t installed solar cost fallen as much as panel prices?
Labor and soft costs haven’t declined at the same pace as panel manufacturing costs.
Do tariffs affect solar panel prices?
Yes — tariffs on imported panels and components can add meaningfully to hardware cost.
Has the expired tax credit made solar more expensive?
Effectively yes for homeowners — without the 30% credit, net cost has increased even though hardware prices haven’t.
What are “soft costs” in solar pricing?
Permitting, design/engineering, sales, marketing, and company overhead.
Will solar installation costs keep rising?
Labor and soft costs may continue rising with inflation, even as panel hardware costs decline gradually.
