Saving Material – The Right Way
In a market with increasing price pressure, solar installers are looking for ways to reduce their material costs. This is understandable and often possible – as long as quality doesn't suffer. Because those who cut corners in the wrong places will pay significantly more in claims and rework.
Where Savings Potential Lies
1. Efficient String Planning
Thoughtful string planning reduces cable lengths on the roof. Fewer cables mean less material for fastening and shorter installation times. The number of required roof penetrations can also be minimized through clever planning.
2. Fewer Penetrations Through Larger Variants
Instead of installing three individual penetrations for two cables each, a single 6-way penetration can be the better choice. NEXCAPE offers variants for 2, 4, and 6 PV cables. One penetration instead of three means: less material usage, less assembly time, and fewer potential leaks.
3. Utilize B2B Quantity Discounts
Installers who regularly install should procure consumables in larger quantities. NEXCAPE offers B2B conditions from 20 units with a quantity discount. A well-stocked material warehouse also avoids costly individual orders and delivery delays.
4. Standardization in Operations
Companies that commit to a few proven products reduce sources of error and accelerate assembly. If every installer knows the same penetration and can install it blindly, the assembly time per roof is significantly reduced.
Where You Should Not Save
- Roof penetrations: Cheap no-name products without UV resistance become a claim trap
- Cable ties: Only use UV-resistant quality ties – white household ties decompose in months
- Sealing material: High-quality butyl tape and sealant are cheaper than water damage
- Grounding: Inadequate grounding is a safety risk and a warranty problem
Calculation Example: Penetration Costs Per System
A typical single-family home system with two strings requires a 4 PV+PE penetration. The material effort is manageable – as is the labor time for assembly, since NEXCAPE penetrations are installed without tools. No MC4 removal, no drilling, no sealing. In total, the quick assembly saves more than the material price.
Quality as an Investment
NEXCAPE roof penetrations made of TPU are manufactured in 3D printing in Germany. The material is UV-resistant, flexible, and durable. Three lengths (105, 125, 150 mm) and six variants cover all installation scenarios. Cost optimization here means: invest correctly once, avoid subsequent costs in the long term.
