Every solar system is six layers doing six jobs — generation, conversion, storage, protection, structure and connection — and knowing each layer’s price is how you read any quote intelligently. Here is the full anatomy with BTECH shelf prices.
1. Generation — panels
605W bi-facial modules, J$25,000 each. Six to thirty per home depending on ambition.
2. Conversion — the hybrid inverter
6kW (J$220,000), 10kW (J$350,000) or 12kW (J$430,000) — turns DC into household AC and orchestrates grid, battery and panels.
3. Storage — lithium batteries
10kWh J$360,000, 16kWh J$395,000, 15kWh J$450,000. Optional but transformative in outage country.
4. Protection — the layer amateurs skip
DC breakers (from J$3,000), AC breakers (from J$2,650), 600V DC surge protection (J$6,000), AC surge protection (from J$5,200), fuses and enclosures. Perhaps 5% of system cost guarding the other 95%.
5. Structure — mounting
Rails J$6,000, mid clamps J$500, end clamps J$450, L-feet J$700 — hurricane-honest attachment into real structure.
6. Connection — cable and connectors
PV cable J$200–J$250/ft, MC4 pairs J$250, grounding hardware. Sized by maths, not vibes.
FAQ
Which component fails first in the tropics?
Sacrificial protection (by design) and bad connectors (by negligence). Buy genuine, crimp properly.
Can I buy components separately from BTECH?
All of them — live stock at btechj.com/shop, counter sales Mon–Sat in Ocho Rios.
Who makes sure they all match?
We do — free system design: 876-777-5488.
