PV Installation on Terraced Houses: Special Requirements
Terraced houses present specific challenges for PV installers. Limited roof areas, fire protection requirements for party walls, and confined spaces necessitate well-thought-out solutions, especially for cable routing.
Typical Challenges
- Small Roof Areas: Often only 30 to 50 square meters are available, requiring efficient module placement.
- Firewall Clearances: Clearances to neighboring buildings must be maintained, further reducing the usable area.
- Restricted Cable Routes: The path from the roof to the inverter is often narrow and winding.
- Neighborly Consideration: Work on the roof must not damage adjacent roofs.
Compact Systems, Compact Feed-throughs
For typical terraced house systems with 4 to 10 modules, two to four solar cable pairs are often sufficient. The NEXCAPE 2 PV or 4 PV variants are ideal here: They bundle multiple cables in a single, compact feed-through, minimizing the number of roof penetrations.
Don't Forget Grounding
Especially in terraced houses with metallic roof structures, grounding is particularly important. The PE variants (2 PV+PE, 4 PV+PE) offer a separate opening for the grounding cable, without requiring an additional feed-through.
Tool-free Installation Saves Space and Time
On the cramped roof of a terraced house, every step counts. The NEXCAPE feed-throughs made of TPU (Thermoplastic Polyurethane) are installed without tools, and the MC4 connector does not need to be removed. This not only saves time but also reduces the risk of damaging neighboring tiles.
Choosing the Right Length
Terraced houses have different roof structures. With the three available lengths of 105 mm, 125 mm, and 150 mm, the feed-through can be precisely adapted to the roof covering height. Made in Germany and produced with 3D printing, NEXCAPE guarantees consistent quality.
B2B Tip for Installation Companies
Companies that regularly equip terraced houses should maintain a mixed stock. NEXCAPE offers quantity discounts for orders of 20 pieces or more, even for mixed variants.
