Detailed Installation Process by HEP

Site Assessment and System Design

Every project begins with a comprehensive site survey, where HEP’s surveyors use irradiance meters, digital pitch gauges, and LIDAR-based shading analysis tools to determine the roof’s solar potential. From these data points, the design team builds a detailed layout using PV*Sol or similar software that simulates annual yield and financial return. The outcome is a tailored proposal featuring:

• Panel count, orientation, and tilt for optimum solar exposure
• DC string configuration to maintain voltage within inverter input ranges
• Inverter selection (single-phase or three-phase) appropriate to property supply
• System losses accounting for cable length, irradiance variance, and temperature coefficients

Electrical Integration and Safety Protocols

HEP approaches electrical integration with an emphasis on safety and longevity. Cables are routed through UV-resistant conduit, secured by stainless steel clips to withstand Newport’s maritime environment. Surge protection devices (SPDs) are installed on both DC and AC sides, protecting sensitive electronics from lightning-induced transients common along coastal locations.

Key steps in the integration process include:

1. Isolating the consumer unit and safely establishing connection points for the solar circuit
2. Installing a dedicated AC isolator adjacent to the inverter for emergency shut-off
3. Commissioning Generation Meters and, where requested, smart metering platforms
4. Performing insulation resistance and polarity tests in accordance with BS 7671, Part 712

Mounting Solution Choices for Newport Roof Types

Newport’s housing stock ranges from Edwardian terraces to modern new-builds, each presenting unique structural considerations. HEP selects mounting systems based on roof covering, rafter spacing, and wind-loading calculations:

• Slate roofs: Stainless steel hooks paired with aluminium rails to minimise slate breakage
• Concrete tile roofs: Adjustable brackets that fit between battens without tile cutting
• Metal standing-seam roofs: Non-penetrative clamps that preserve waterproofing integrity
