Photovoltaic

 

Photovoltaic (PV) systems are transforming energy generation. While solar panels generate electricity, they need a reliable way to store and manage that energy.

Overall reasons to choose primary lithium battery and HPC battery on photovoltaic systems:

  • PV farms face extreme temperature swings (deserts, snowy areas, rooftops).
  • Many regions (EU, US, China) require long-term data logging and reliable monitoring of PV performance for subsidies, carbon credits, and compliance.
  • 24/7 and safe power solution for no more than 10 years on Virtual Power Plant, even during a grid outage.

Primary lithium batteries and HPC (Hybrid Pulse Capacitor) batteries are playing a growing role in powering photovoltaics. Their unique capabilities enhance energy storage and supply in PV setups.

Photovoltaic systems

Is photovoltaic the same as solar?

Often, the terms “photovoltaic” and “solar” are used interchangeably but they are not exactly the same.

Solar energy is a broad term that includes all technology harnessing energy from the sun, including solar thermal and photovoltaic.

And what is photovoltaic? Photovoltaic specifically refers to converting sunlight directly into electricity using solar panels through photovoltaic solar cell.

These panels are the core of a photovoltaic system, which includes not just the panels but also batteries and other electronic components to store and manage energy.

So, while all PV is solar, not all solar is photovoltaic.

Understanding this definition helps clarify the critical role of batteries like primary lithium and HPC in PV systems, ensuring continuous power supply even when the sun isn’t shining.

Primary Lithium Batteries in Photovoltaic Systems

Primary lithium batteries are widely used in PV systems for their high energy density, long storage life, and low maintenance. These batteries do not recharge but offer reliable backup power.

In PV applications, primary lithium batteries serve well in off-grid and remote photovoltaic solar power setups, where maintenance accessibility is limited.

Primary lithium and HPC batteries are not used for large-scale energy storage like home backup systems, which rely on rechargeable batteries.

Instead, they power the small, critical components that monitor, manage, and secure the photovoltaics itself.

They power control units, monitoring devices, and remote sensors that keep solar photovoltaic systems efficient and safe.

These batteries provide a steady and durable power source to keep the photovoltaic system components running optimally under varied environmental conditions.

HPC Batteries Supporting Photovoltaic Systems

HPC batteries combine lithium-ion chemistry with capacitor technology for superior performance in fast charge and discharge conditions.

This makes them ideal for smoothing out power fluctuations in PV systems caused by changing sunlight or load demands.

HPC batteries’ resilience in harsh conditions and ability to deliver high pulse currents help maintain stable energy supply and protect sensitive electronics in solar PV installations.

They are increasingly used in solar power backup devices, smart energy meters, and grid-connected photovoltaics to enhance power quality and reliability.

Industries Using These Batteries in PV
  • Off-grid solar lighting and communications equipment
  • Residential and commercial solar home energy storage systems
  • Solar-powered IoT devices used for environmental and agricultural monitoring
  • Smart solar street lighting and public infrastructure
  • Remote telemetry, weather monitoring stations, and marine buoy systems
  • Grid-tied solar inverters and uninterruptible power supplies (UPS) for clean energy
  • Solar panel monitoring and optimizers
  • Security and Surveillance
  • Weather Stations and Environmental Sensors
  • Other smart grid components

Industries benefiting include renewable energy providers, smart city planners, agriculture, marine research, and telecommunications.

These batteries enable uninterrupted photovoltaic system operation, especially in remote or off-grid areas.

Examples of These Batteries Used in PV

  • Smart Junction Boxes:

    The junction box on the back of a solar panel contains bypass diodes and wiring.

    Smart junction boxes use sensors and a primary lithium battery to monitor the performance of the diodes.

    They can report on a diode failure, which helps technicians fix problems faster.

  • Wireless Data Loggers:

    Data loggers are used to track a solar panel’s performance over time.

    A wireless data logger can be placed in a remote area and left for years.

    It uses a primary lithium battery to record data and transmit it periodically to a central system.

  • Load Monitoring:

    In off-grid systems, a battery can be used to monitor the power consumption of a load.

    This helps users manage their energy more effectively

    The battery in the monitoring device ensures it can continue to collect data even if the main solar battery is low on charge.

  • Security Locks and Alarms:

    The physical security of solar panels and power storage units is a concern.

    Electronic locks, alarms, and sensors on gates or equipment enclosures can be powered by these batteries.

    They provide a reliable, long-term power source for a device that is rarely used but must be ready to function at a moment’s notice.

  • Safety and Emergency Systems:

    In case of a fire or other emergency, a PV system might have a special rapid shutdown switch.

    A small, primary lithium battery can be used to power the wireless signal for this switch.

    This ensures that a fire crew can safely disable the system even if the main power is compromised.

  • Solar panel charge & discharge battery:

    Not for storing solar energy, but powering supportive devices inside the photovoltaic ecosystem.

    Primary lithium battery ensure reliable operation of PV monitoring boxes, smart meters, communication gateways, and IoT sensors.
  • Heliostat: 

    When sunlight hits the solar receiver, it generates superheated steam, which is used to turn a turbine and generate electricity.

    Our rechargeable battery pack will drive the heliostat motor and power the device communication.

    Rechargeable batteries help eliminate the expensive cables and wiring required to power the heliostat motor and control module.
