1. PV Modules (Solar Panels)

Main Types:

Monocrystalline Silicon (PERC, TOPCon, HJT) – Most common for residential, commercial and utility-scale projects.

Bifacial Modules – Capture light from both sides; increasingly used in ground‑mount and agrivoltaic plants.

Flexible / Lightweight Modules – Designed for metal roofs, RVs, marine applications, and building-integrated PV (BIPV).

2024/2025 Trends:

n‑type TOPCon and heterojunction (HJT) are rapidly replacing traditional PERC.

Module power ratings now routinely exceed 600 W for utility projects.

Efficiency records for perovskite‑silicon tandem cells have reached 34.6% in the lab.

2. Inverters & Power Electronics

Main Types:

String Inverters – Centralized units, cost‑effective for simple roof layouts.

Microinverters – Module‑level optimization; ideal for roofs with shading or complex orientations.

Power Optimizers – Combine module‑level MPPT with centralized inversion.

Hybrid Inverters – Integrate battery storage; essential for self‑consumption and backup power.

2024/2025 Trends:

1500 V inverters are standard for large ground‑mount plants.

Grid‑forming capabilities are becoming a key feature for grid stability.

AI‑driven energy management software is increasingly embedded in inverter platforms.

3. Mounting Systems

Main Types:

Roof Mounts – Rail‑based, rail‑less, ballasted, and clamp‑based solutions for sloped, flat, and metal roofs.

Ground Mounts – Fixed‑tilt, adjustable‑tilt, and single‑/dual‑axis tracking systems.

Specialty Systems – Agrivoltaic high‑clearance mounts, floating PV structures, and flexible / cable‑supported systems.

2024/2025 Trends:

Non‑penetrating (ballasted, clamp‑based) systems are growing rapidly for commercial rooftops.

Screw piles / ground screws are replacing concrete foundations for faster, removable installations.

Flexible mounts with spatial cable‑net structures have demonstrated resilience up to Category 17 typhoons.

4. Energy Storage Systems (Batteries)

Main Types:

Residential Batteries – Typically 5–20 kWh; AC‑coupled or DC‑coupled.

Commercial & Utility Storage – Containerised lithium‑iron‑phosphate (LFP) or emerging sodium‑ion systems.

Thermal Storage – Molten salt systems, often paired with CSP.

2024/2025 Trends:

Lithium‑iron‑phosphate (LFP) dominates for safety and cycle life.

Sodium‑ion batteries are entering commercial production as a lower‑cost, resource‑abundant alternative.

DC‑coupling between PV, storage, and inverters improves round‑trip efficiency.

5. Balance of System (BOS) Components

Key Components:

Cable Management – Cable trays, hangers, clips, and trunking systems designed for UV resistance and long service life (25+ years).

Connectors & Fasteners – MC4 connectors, stainless steel bolts, grounding clamps, and anti‑loosening hardware.

Monitoring & Control – SCADA systems, weather stations, and AI‑powered performance analytics platforms.

Bird Deterrents & Security – Physical barriers (brushes, mesh), bird spikes, and perimeter fencing.

6. Specialised & Emerging Products

Agrivoltaics Solutions – Elevated mounting structures (≥2.5 m height) with wide spans to accommodate farming equipment.

Floating PV (FPV) – Modules, floats, and mooring systems for reservoirs, lakes, and ponds.

BIPV (Building‑Integrated PV) – Solar tiles, glass, and facade elements that replace conventional building materials.

Off‑Grid / Portable Kits – Pre‑assembled ground‑mount kits, balcony solar systems (800 W plug‑and‑play), and deployable solar arrays for temporary sites.
