The Innovation

Dual Energy
Harvesting

The world's first solar tile that generates electricity AND heats your water through a passive thermosiphon system requiring zero external power.

Photovoltaic Generation

Monocrystalline silicon cells with -0.30% to -0.40% per °C temperature coefficient, optimised for UK conditions.

Thermosiphon Cooling

Passive fluid circulation through natural convection—no pump required, no energy consumed, no mechanical failure points.

Temperature Optimisation

Cells maintained at 15-35°C optimal range, delivering 8-15% more electricity than uncooled alternatives.

Standard UK Dimensions

Direct replacement for cement tiles conforming to BS EN 490/491. No roof structure modification required.

Temperature vs Efficiency

15-35°C OPTIMAL 0% to -5%
35-45°C ACCEPTABLE -5% to -10%
45-65°C DEGRADED -10% to -20%
>65°C CRITICAL >-20%

Hobson Tiles actively regulate cell temperature to maintain peak efficiency

The Advantages

Why Choose
Hobson Tiles?

01

Zero Structural Changes

Direct replacement for standard UK cement tiles. Your existing roof structure remains untouched.

02

Passive Operation

The thermosiphon requires no pump, saving 50-100W versus active systems. Nothing to fail, nothing to maintain.

03

Dual Energy Harvest

60-75% combined efficiency versus 15-22% for PV-only. Generate electricity AND heat your water.

04

Optimised Efficiency

Active cooling keeps cells in the 15-35°C sweet spot, delivering 8-15% more electricity than standard panels.

05

Extended Lifespan

Lower operating temperatures reduce thermal degradation. Expect 30-35 years versus 25-30 for conventional systems.

06

Significant Savings

40-70% reduction in summer water heating costs. 10-30% annual reduction overall.

07

Standard Installation

Any qualified roofer can install. No specialist solar training or equipment required.

08

UK Climate Optimised

Cell selection and cooling parameters specifically tuned for temperate maritime conditions.

The System

How It
Works

A complete passive solar system that generates electricity, heats water, and regulates itself—all without pumps, controllers, or external power.

Thermal Storage Hot (35-50°C) Cool (15-25°C) ΔH ≥ 1.5m ⚡ To Grid/Battery
1

Solar Absorption

Sunlight passes through low-iron tempered glass to monocrystalline PV cells, generating electricity and heat.

2

Heat Transfer

Copper thermal interface conducts heat from cells to serpentine tubing, warming the circulating fluid.

3

Natural Circulation

Heated water rises to loft-mounted storage tank. Cooler water descends to replace it. No pump needed.

4

Dual Output

Electricity flows to your home or grid. Pre-heated water reduces your boiler's workload by up to 70%.

Installation Configurations

Series Connection

Maximum temperature rise (ΔT = 15-20°C). Ideal for hot water priority.

Parallel Connection

Uniform efficiency across all tiles. Best for electricity priority.

Recommended

Hybrid Series-Parallel

Balanced performance. Moderate temperature rise with consistent efficiency.

Rapid Installation

Quick-Connect
Coupling System

Tool-free push-fit connections enable installation in under 3 seconds per tile. Glass-reinforced polymer housings with stainless steel collet rings ensure leak-free operation at up to 90°C and 10 bar pressure.

  • 500+ connect/disconnect cycles
  • EPDM O-ring seals rated to 90°C
  • 8mm nominal bore for unimpeded flow
  • No specialist tools required
