Technology

Since our luminaires must resist over time in the harshest conditions, our products are manufactured with aluminium, the perfect material for natural corrosion.

Beyond materials, we pay a particular attention our surfaces treatments and coating.

We opted for AKZO NOBEL powder coating, offering exceptional resistance performance in the most demanding conditions.

Aluminium and AKZO NOBEL powder coating allows Bullard Solar luminaires to resist high temperatures and humidity, UV discolouration from long sun exposure, and salt corrosion from seaside locations.

Battery is a key component of solar lighting solutions. Quality battery technology determines the performance, lifetime, and price of a solar luminaire

From the beginning, Bullard Solar has successfully opted for the LIFEPO4 Lithium battery which guarantees an operating lifetime of more than 10 years.

Many manufacturers, by lack of knowledge or for cost saving reasons, opt for other technologies, such Lithium Ion or Nimh, resulting in poor product quality and short lifetime.

With over 400,000 products installed worldwide in various climates, Bullard Solar batteries have proven their quality and performance.

Our LED modules must achieve the longest lifespan possible. In our search for excellence, all our luminaires are equipped with PHILIPS LED Chips, well known and recognised for their performance and robustness with more than 80,000 hours lifespan and a performance of more than 196 Lumens per Watt.

In addition, electronic protection devices prevent any overheating of the various components.

Temperature management in our luminaires is deliberately very safe; we keep the temperature of our LED modules much lower than the maximum allowable temperatures resulting in a increased lifetime.

For the sake of performance and reliability Bullard Solar uses monocrystalline photovoltaic panels high performance.All our cells are selected with the greatest attention and only GRADE A and an efficiency greater than 19.4%.

Bullard Solar luminaires are equipped with microwave detectors.

The microwave detectors that use the Doppler effect (like car radars) to detect a presence and measure the distance. The sensor emits a high frequency wave to bounce off and analyze the presence.

Since the microwaves only detect specific objects, detection reliability increases resulting in:

• Much better reliability compared to the Infrared detector
• Up to 360° Directivity
• Insensitivity to other environmental variations such as light, color, temperature, etc.
• Long and stable detection range

The charge controller is the brain of the solar lighting system.
It allows regulation and protection of the battery charge as well as the management of lighting and its programming.

The electronics of the Bullard Solar controller is completely encapsulated in an aluminum box providing it with tightness and perfect heat dissipation.

The controller also acts as a protection element for all components against:
Overload / Overcurrent / Overtemperature /
Overvoltage / Overload / Overdischarge

In order to facilitate all maintenance operations and especially to diagnose any possible problem without having to intervene mechanically on the luminaire, Bullard Solar luminaires are equipped with a Wireless diagnosis system via remote control.

With a simple click get real-time information such as:

• Automatic diagnosis in the event of a malfunction
• State of charge and history of the Battery
• Real-time charging and History of production of the Solar Panel
• Age of the product and date of installation
• Temperature and its history

As part of its continuous development effort, the Bullard Solar team is proud to have developed a special tool for surveillance to distance of our solar street lights. Bullard Solar Bridge uses low frequency LORA or Zigbee technology to monitor a batch of solar street lights in real time.

BULLARD SOLAR BRIDGE allows the control of luminaires such like:
Programming / Real-time operation monitoring / Fault alert / Location / Operation history
