Solar lighting by Novéa Designed to last
A solar standalone lamp incorporates a battery that stores the energy accumulated during the day. This battery is dimensioned (unit in Wh, Watt hour) according to the need of lighting, and the number of days of desired autonomy without sun. By experience, Novéa offers a range of between 3 and 10 days autonomy depending on the geographical area. This autonomy allows to illuminate in the desired way, all the year. Concretly, is the lighting has to operate at 20 W during 6 hours every night, we size the battery of our solar lamppost to ensure this consumption (20W during 6 hours) during 5 nights (example for city of Denver, at the worst case of the year). This autonomy is clearly indicated in the energy studies that Novéa provides for each project.
In addition, in order to offer maximum autonomy, Novéa offers optimized lighting management (presence detection, lowering of power, time slots).
And if the days covered are prolonged and the battery reaches a critical level, Novéa has developed a calculation algorithm to reduce the power of lighting to increase the autonomy.
The Novéa concept of Endurance + Technology batteries, developed for more than 7 years with the CEA of Grenoble, allows to announce a life of more than 20 years and to guarantee them 10 years on the temperate zones (France, DOM – TOM, for example).
This concept combines scientifically analyzed Lithium Iron Phosphate batteries with dedicated and patented electronic management. The perfect mastery of these essential components, offers the greatest durability of the market.
These batteries have been scientifically recognized as the most successful for the solar lighting market.
A solar streetlight remains public lighting furniture. It is therefore subject to the same maintenance conditions as traditional public lighting (regular checking of the bolts, cleaning of the luminaire protection…).
However, so-called “heavy” maintenance is non-existent since :
Our Endurance + batteries are not sensitive to heat (operating up to +65 ° C).
For very cold areas, our technology includes a heating system to always leave the battery in optimal conditions (> 0 ° C).
This heater takes a little energy from the battery to warm it up. This energy is taken into account in our energy balance to ensure perfect operation all year round.
The purpose of a stand-alone street lamp is to illuminate. It is therefore very important to use the best technologies in public lighting.
By approaching the Ragni Group, which has its own lighting development office, Novéa offers high quality LED luminaires worthy of the standards required in public lighting.
Cast aluminum fixtures, flat tempered glass protection and IP and IK ratings ensure a very long service life for luminaires.
From a photometric performance point of view, Novéa integrates the latest LED technologies of recognized brands and offers outputs of more than 160 lm / W at the output of the luminaire.
Novéa proposes 6 different standard optics in order to optimize the lighting study and thus the lighting power and the number of luminous points.
The only difference with grid-connected public lighting products is the need to manage energy consumption well and often to offer lighting management systems (detection, lowering, time slot …).
Several operating programs are possible (presence detection, dimming mode, time slots, etc.).
Depending on your project, the program will be defined when ordering. This will be validated by our energy balance to ensure smooth operation throughout the year.
The lamp post will be programmed in the factory. There will be no specific commissioning to perform.
In case of reprogramming, we will provide you with a key integrating the new program. This key will be connected to the product’s electronic management. It will be necessary to inform us beforehand of your wish to modify the program. This will be validated by our design office. Once validated, this key will be sent to you.
Our NoveaControl system allows remote reprogramming.

Our solar panels are tilted mainly at 15° or 30°, depending on the latitudes, to optimise energy production at the worst case of the year. The impact of the mechanical sizing, due to the wind factor of the solar panel, is also considered to choose the inclination.
The final objective is to size the power of the solar panel according to the energy needs of the project, its geographical area and its inclination.
As part of the Ragni Group, which is approved EN40 (standard on the mechanical strength of masts) Novéa is able to size the masts according to wind resistance and weight. Indeed this very important and reassuring competence for the end customer makes it possible to ensure a perfect holding of the mast for all the wind areas.
The Novéa masts are therefore dimensioned and manufactured specifically according to the wind resistance and the total weight of the equipment. Our regular installations and for several years, in the Antilles or Reunion which are in the most critical wind areas, prove that our sizing is adequate.
In addition, Novéa will be able to systematically provide the calculation notes on the behavior of the solar street lamp and the sizing of the concrete block, in order to ensure a safe installation, made in the rules of the art.
