BEKA SOLAR
IP 65
IK 10
The most customizable solar solution for road and urban applications
Our solar street light for outdoor residential and public applications gives you a full customizable option to suit all your off-grid solar lighting requirements.
The BEKA SOLAR, combined with the ZIYA luminaire, provides a reliable lighting solution with a high Ingress Protection level (IP 65) that withstands high ambient temperatures and vandalism (IK 10). The ZIYA range is a sustainable off-grid performer with a superior lumen/watt ratio.
The photovoltaic process is optimized by efficient Polycrystalline solar module technology to maximise solar energy. This in turn offers the best energy storage options and autonomy available on the market with our range of battery options, namely Lead, Lithium and the new SuperCapacitor. This SuperCapacitor removes the depth of discharge (DOD) issues, and furthermore offers extended life and discharge cycles.
Controlling the whole system and using this solar energy by programming the MPPT charge controllers protects and optimizes the system from any internal and external factors, like thermal environmental changes when charging the batteries.
The BEKA SOLAR offers the renewable lighting solution to cover your geographical and application needs with extended lifetime and optimization.

Technical Definitions
Lead-based AGMLead-based batteries remain the most widely used battery technology to date. With the introduction of AGM (Absorbent Glass Mat) technology, it has become maintenance free for the lifetime of the battery. With the introduction of solar technology, the lead-based battery has become a reliable and very cost efficient storage device for this type of deep cycling application.
Battery pack operating temperature: -20°C to +60°C
SuperCapacitorSuperCapacitor technology, a non chemically-based technology, allows a depth of discharge (DOD) of 100% without any reduction of charge capacity. It offers an extreme long lifetime capability and strong thermal resistance of a capacitor technology with an integrated Battery Management System (BMS) that controls the charging and discharging cycles of the capacitor bank. This combination offers a highly durable industrial and robust battery pack to store solar energy with the added advantage of an expected 1 000 000 cycles, resulting in the battery pack lasting for the lifetime of the system.
Battery pack operating temperature: -30°C to +80°C
Solar module
Lithium-ionLithium-ion based battery packs have the added advantage that they have a higher power density than lead, which means they have more available power for the same mass of a lead battery. This advantage, combined with the longer life expectancy and higher rate of depth of discharge (DOD), offering an attractive option for solar lighting applications, resulting in a longer battery lifetime. Our renowned Tier 1 branded cells ensure the highest quality product. In addition, all Lithium-ion battery packs have an integrated Battery Management System (BMS) which monitors the health, charging and discharging of the battery pack. This safeguards the cells so that they are not over charged or discharged, maximising their lifetime.
Battery pack operating temperature: -20°C to +50°C
The solar panels are ISO and TÜV certified and carry a 10-year product warranty. Hail-resistant and corrosion-proof. Rated outputs on the panels are 90% minimum for the first 10 years and 80% minimum after 25 years. Panel outputs are designed to cater for all annual environmental conditions.
Battery options
Please note: Batteries require special storage. Please consult us for more information.
Intelligent luminaire drivers are programmed if required in the factory with complex dimming profiles. Up to 5 combinations of time intervals and light levels are possible. This feature does not require any extra wiring. The period between switching on and switching off is used to activate the preset dimming profile.

Charge controller
The MPPT charge controllers can harvest up to 30% more energy in clouded sky conditions compared to PWM charge controllers. The charge controllers have a load output connection that can be programmed to switch the luminaires off when the battery voltage drops to critical levels. This allows for the batteries to be protected from over discharge. The charge controllers have integrated temperature sensors that can compensate for thermal environmental changes when charging the batteries. The charge controllers use a 3-step charging process with all three charge levels programmable depending on the battery technology selected. They offer a 5-year warranty.
Autonomy Days
Autonomy Days refers to the number of nights/cycles a luminaire will continue to work without receiving a charge/being charged from the solar panel, due to overcast weather conditions. The number of autonomy days is aligned to the battery depth of discharge resulting in sufficient capacity after a night/cycle.
