Time is Money – Especially on the Roof
Every minute a solar installer spends on the roof costs money. Scaffolding rental, personnel costs, and lost order capacity quickly add up. Reducing installation time per system increases the entire operation's profitability. An often-underestimated lever for this is the roof penetration.
Time Comparison: Conventional Method vs. NEXCAPE
With conventional cable penetration using sealing sleeves, several work steps are required that are eliminated with a specialized PV penetration:
| Work Step | Conventional | NEXCAPE |
| Disassemble MC4 connectors | 5–10 Min. | Eliminated |
| Process/drill tiles | 5–10 Min. | Eliminated |
| Adjust sleeve | 3–5 Min. | Eliminated |
| Feed cable | 3–5 Min. | 2–3 Min. |
| Reassemble MC4 connectors | 5–10 Min. | Eliminated |
| Check for leaks | 2–3 Min. | 1–2 Min. |
| Total per penetration | 23–43 Min. | 3–5 Min. |
ROI Example Calculation for a Solar Installation Company
Assumptions for the calculation:
- Average of 2 roof penetrations per system
- 15 systems per month
- Installer hourly rate (internal): €55/h
- Time savings per penetration: 25 minutes
Monthly Savings
30 penetrations × 25 min. = 750 minutes = 12.5 hours
12.5 hours × €55/h = €687.50 per month
Annual Savings
€687.50 × 12 = €8,250 per year
This does not yet include the possibility of taking on additional orders due to the freed-up time.
Further Savings Potential
In addition to the pure installation time, there are further economic advantages:
- Less tools: No drill, no MC4 tool needed for penetration
- Lower error rate: Without MC4 disassembly, a common source of error is eliminated
- Shorter scaffolding times: Faster assembly means shorter scaffolding rental
- Fewer complaints: Professional penetrations made of UV-resistant TPU last longer
B2B Volume Discount from 20 Units
NEXCAPE offers volume discounts from 20 units – ideal for solar installation companies that install regularly. With higher quantities, the ROI improves even further. All variants – 2, 4, and 6 PV cables, with and without PE – are available from stock in Germany in lengths of 105 mm, 125 mm, and 150 mm.
