Why PVT Type E?

Traditional solar systems face a major challenge:

PV panels generate electricity, but most of their heat is wasted.

Solar thermal systems produce heat, but cannot supply electricity.

As a result:

Energy utilization remains low

Module temperature rises, accelerating aging

Power output decreases due to "hot spot effect"

PVT Type E completely breaks this limitation.

It integrates photovoltaic + photothermal technologies within one module, functioning both as a power station and a thermal energy plant, pushing the overall solar utilization rate up to 60% and enabling a true high-efficiency, low-carbon energy system.

Four Core Advantages

1. Dual-Energy Synergy — Zero Energy Waste

Integrated thermo-PV coupling technology

Real-time temperature control keeps the module below 45°C

Solves hot-spot and high-temp power decay

Extends system lifespan and improves long-term ROI

📌 Result: Up to 50% higher total energy yield compared to traditional PV.

2. Vacuum Lamination — Stronger Thermal Output

A vacuum-assisted lamination structure provides:

Lower thermal resistance

Faster heat transfer

Up to 40% higher thermal utilization efficiency

🛁 Supports high-demand usage: Hot water / winter heating / heat pump supply without energy waste.

3. Intelligent Temperature Control — Higher Efficiency, Longer Life

Monitors and regulates surface temperature in real time

Maintains uniform temperature difference within ±1°C

Thermal output can reach 2× electrical generation

💰 One investment, double returns: Electricity + heat recovery = far greater economic benefits than standard PV.

4. Smart Connectivity & Lower O&M

Built-in sensors + intelligent control module

Connects with building energy management (BEMS)

Adaptive matching of heating and electricity load

📉 Operation & maintenance cost reduced by up to 35%

Multi-Scenario Applications

Application Scenario	System Benefits
Office / Residential Hot Water Supply	24/7 low-cost hot water, replaces electric/gas heaters
Swimming Pool Heating & Seasonal Extension	Low-cost heating during spring & autumn, longer pool usage period
