Core Components of PVT solar electric and thermal system
A complete PVT hybrid solar electric and thermal system is an integrated solution consisting of:
Hybrid PVT solar collectors: High-efficiency monocrystalline solar cells laminated onto a specialized thermal heat exchanger.
Insulated Storage Tank: A pressurized tank (typically 200L to 500L) with dual coils for heat exchange and backup heating.
Smart Control Station: A centralized hub featuring a circulation pump, pressure gauge, and a microprocessor to manage energy flow.
Pre-insulated Piping: Specialized lines designed to transport heat-transfer fluid with minimal energy loss.
How It Works
Electricity Generation: Sunlight hits the solar pv panels on the top layer, generating DC power for home use or battery storage.
Heat Absorption: Simultaneously, the thermal absorber underneath the cells captures the infrared heat that usually causes panels to overheat.
Active Cooling: A heat-transfer fluid (water or glycol) is pumped through the back of the panel. This fluid absorbs the heat, cooling the solar cells.
Water Heating: The warmed fluid travels to the storage tank's heat exchanger, transferring its energy to the domestic water supply.
Efficiency Loop: The cooled fluid returns to the panel to repeat the process, maintaining the PV cells at an optimal operating temperature.

General Questions & Operation
What exactly are PVT hybrid solar panels?
PVT (Photovoltaic Thermal) solar panels are a single, integrated module that generates both solarelectricity (PV) and solar heat (thermal energy) simultaneously from the same surface area. They combine solar cells with a thermal collector/heat exchanger on the back.
How do PVT systems improve efficiency?
By flowing a fluid (water or glycol mixture) through the back of the panel, the system captures excess heat that would otherwise be wasted. This process also cools the PV cells, which makes them operate more efficiently and can increase electricity generation by up to 15% in warm weather.
Can I produce hot water and electricity at the same time?
Yes. The core design of the PVT solar system is to produce both hot water and electricity for households.
Do they work on cloudy days or in winter?
They still generate energy (both electric and thermal) on cloudy days, though less than on sunny days. A backup electric element or conventional boiler should be integrated into the storage tank to ensure a consistent hot water supply during prolonged periods of low sunlight.
How much roof space is needed?
A major advantage of PVT systems is their space efficiency. A single PVT panel produces 2-3 times more total energy than a standard PV panel of the same size, making them ideal for homes with limited roof area. Sizing depends on household size and hot water needs, but generally 2-3 panels are sufficient for a 200L domestic hot water system.
Can a PVT system be integrated with an existing water heating system?
Yes, the PVT solar system is designed to work alongside existing conventional water heaters as a pre-heater, reducing the load on your traditional system and thus significantly cutting costs.
Does PVT solar installation affect water pressure?
No, the solar heating system typically operates in a closed loop (split system) and does not affect your home's main water pressure.
How much do they cost compared to standard solar panels?
PVT solar systems typically have a higher upfront cost than separate PV and thermal systems. However, the combined energy savings and high overall efficiency can lead to a good return on investment over the system's long life.
What maintenance is required?
Maintenance is generally minimal and similar to standard solar thermal systems: periodic cleaning, checking fluid levels (glycol mixture in cold climates), and ensuring the pump station is functioning correctly. They have a long lifespan of 20-25 years or more.
To help you decide if a PVT system is the right fit, could you share details about your estimated daily hot water usage and your home's roof orientation?
