PV System

Climate changes in recent years have brought ecological alert. To reduce energy reliance and lower costs,development of renewable energy, particularly of solar technology, has attracted increasing attention.A typical solar photovoltaic cell applies P/N type semiconducting materials to form two(positive and negative) electrodes.

1. Electricity can be extracted from the solar cell by connecting to its positive and negative electrodes.

2. Upon absorbing the photon energy supplied by sunlight, electrons and holes inside semiconducting materials are excited from their current atomic orbital and travel through the cell till they reach an electrode.

3. Solar energy can then be generated and stored via photo-thermal conversion (e.g. solar collectors) and photovoltaic conversion (e.g. photovoltaic modules).


Tatung Company provides three options of power supply:

1. Grid-connected System: To be connected to the electrical grid in case of power shortage or output fluctuations.

2. Stand-alone System: Rechargeable batteries are integrated into the PV system for power storage and stabilization.

3. Emergency-based Hybrid Module: The system supplies power to the grid during the day, then draws power for the grid at night. In case of power interruptions, the hybrid module can draw power from integrated batteries.


Tatung offers the following service for setup and commission of PV systems.
1. Site planning and surveying
2. Software simulation
3. Design evaluation
4. System implementation
5. System on-Grid applications
PV-ESCO offers a brand new business model for the energy service industry. Candidate sites including new and existing buildings are vetted and chosen for construction and setup of PV systems. The generated electricity can then be sold back to the grid as source of income for the property owners.
Our experts utilize the wide range of tools available to them to customize PV system on a case by case basis.
Tatung's Smart Energy Management System is integrated into all new PV system to maximize energy efficiency and cost reductions.
Tatung coordinates the supply, construction, installation and maintenance of PV systems and obtains secure financial backing the feasibility studies from its partner banks.

Main Achievements

With growing awareness of the effects of climate change, environmentally friendly technologies have come to the forefront of dealing with this pressing issue.

Photovoltaic or solar cell technology has come down greatly in price while continuing to become more efficient.

When sunlight strikes a PV cell, electrons inside the semiconducting materials are excited out of their orbitals and travel through the cell to a contacting electrode. This energy can also be generated and stored via photo-thermal conversion in addition to conventional PV generations.
