Renewable Power AND Hot Water in One System

Solar Photovoltaic Thermal (PVT) systems offer significant efficiency dividends for hot water-intensive businesses by converting solar irradiance into both electricity and usable heat. These systems harness the solar spectrum more effectively than traditional photovoltaic (PV) panels by mitigating thermalization losses-where excess heat is not converted into electricity and is usually wasted. PVT systems capitalize on this otherwise lost thermal energy by transferring it from the PV cells to a fluid, yielding additional thermal energy that can be used for heating purposes.

The technical advantage of PVT systems lies in their ability to achieve considerable thermal efficiency, typically around 60%, despite the presence of optical losses where some sunlight is reflected or not transmitted through the panel's cover. Electrical gains in PVT systems are also notable, standing at around 15%.

These figures underscore the system's capability to transform a substantial fraction of the solar spectrum into electrical energy, which is crucial for the overall energy yield of the system. Meanwhile, heat losses through conduction, convection, and radiation are an area of focus to ensure thermal efficiency remains high.

Minimizing these losses is critical to enhancing the PVT system's performance and maximizing the return on investment through efficiency dividends. The dual functionality of PVT systems to provide both heat and power makes them a financially and environmentally attractive choice for businesses requiring large quantities of hot water.

Solar Electric-Thermal CHP Adoption in Europe

Solar electric-thermal CHP systems have gained traction across Europe, offering a dual solution for electricity and heat generation. Notable examples include:


Germany's Solar District Heating Projects: In Germany, several municipalities have implemented solar electric-thermal CHP systems to provide district heating. Freiburg's Vauban district stands out, where solar panels not only generate electricity but also capture excess heat for space heating and water heating purposes.


Spain's Solar Industrial Parks: In Spain, industrial parks have embraced solar electric-thermal CHP solutions to meet their energy needs sustainably. These systems provide a reliable source of electricity while simultaneously catering to industrial processes requiring heat, such as food processing and manufacturing.

Solar Electric-Thermal CHP Adoption in Asia

Asia is also witnessing a surge in solar electric-thermal CHP adoption. Countries like China, India, and Japan are leveraging this technology to address energy security concerns and combat climate change. Examples include:


China's Solar-Powered Industrial Facilities: Chinese industries are increasingly integrating solar electric-thermal CHP systems into their operations. Manufacturing plants, textile factories, and chemical processing facilities utilize these systems to reduce reliance on fossil fuels and lower operational costs.


Japan's Solar CHP Residential Communities: In Japan, residential communities are turning to solar electric-thermal CHP solutions for energy independence. These integrated systems provide electricity for households while utilizing excess heat for water heating, space heating, and other domestic needs.
