A. Photovoltaic/INVERTER Systems:

We specialize in manufacturing and marketing of power solutions products and systems (Solar Powered Off Grid and Hybrid Systems, Inverters /Ups, etc), Our high-quality solar street lights are commercial quality lighting systems for residential streets, parking lots and security lighting. The applications for solar powered outdoor lighting systems are endless. These units can be used for: Security and safety lighting, rural area lighting, Dock lights and so on. The costs of trenching and installing underground wiring often   make a solar street lighting system an economically feasible lower cost option.

B. Solar Street Lighting Solution

 Our solar street lighting systems are a complete turn key solution. All components needed for installation are included (except for the mounting pole). The systems are designed for easy installation. The efficient microprocessor automatically activates from sunset to sunrise. The in-built timer regulates the hours the light stays on; also regulates the battery, preventing it from overcharging and over discharging. The system is able to operate for at least 3 consecutive days without sunlight.

The luminaries are available with either, low pressure sodium (LPS), fluorescent (FL) lamps, or LED’s. The LPS lamp is a monochromatic (yellow-orange) light source, delivering the highest possible lumens per watt. Compact fluorescent lamps provide slightly less lumens, but produce a white light (4100K), which appears brighter than low pressure sodium lamps and should be used in areas where co lour rendition is desired.

Efficient Solar Street Lighting using LED

We also offer street lighting systems which use LED lights that are extremely efficient, and durable light sources. Only 1/10 the power is required with LED fixtures to produce the same light intensity as an incandescent bulb. Four packages are available that allow you to choose the lighting solution that best meets your needs.   The LED Street Light is available with either 3000 lumens to 4600 lumens, which are equivalent to 150 W and 450 W incandescent light bulbs respectively.

Powerful Solar Module

The solar modules feature high efficient solar cells, and industrial construction with a rugged tempered glass face and aluminum frame. Plus, the power output warranty ensures that, the lighting system will generate power for decades into the future. The LED Street light has the option of one or two panels depending on the application.

Solar Controller

The solar controller is perfect for lighting control functions. This controller protects against reverse current and carries a 6 months warranty. The solar controller provides 10 different options. For example, after the sun sets the controller can operate the light for two or for three hours then turn on one hour before sunrise or run dusk to dawn.

WHY SOLAR?

The answer is simple Safety, Health & Environment.
Free and Clean electricity from the Sun would appear to be the future power of our generation. Now solar photovoltaic modules are available at much lower prices then ever before, it would be cheaper to obtain electricity directly from the sun.

Each stand-alone, solar powered generating system can provide power for up to 24 hour a day. Solar lights can be designed to provide illumination automatically from dusk to dawn. Each system can charge itself, store and produce electricity even on dull days.
Recreation parks and gardens Solar powered lights are safer if as they operate at 12V DC. At this voltage there is no danger of electro-caution, a most beneficial safety feature in places frequented by children.
Moreover solar powered lights can be installed almost anywhere: in rugged terrain, offshore, in remote areas where electricity is needed but not available.

The basic goal of street lighting and road way lighting is to patterns and level of horizontal pavement luminance and of horizontal and vertical luminance of objects. Lighting design is concerned with the selection and location of lighting equipment so as to provide improved visibility and increased safety while making the most efficient use of energy within minimum CAPEX and most importantly OPEX.

The preferred solution is based on lighting illumination concept, which is universally used. It is based on the premise that, by providing a given level of illumination and uniformity of distribution, satisfactory visibility can be achieved.

Design process, by definition lighting designs according to illumination methods relies on the amount of flux reaching the pavement and the uniformity of the light on the pavement surface .The steps are:

  1. Determination of the foot-candle value by assessing the facility to be lighted.
  2. Selecting the type of light source
  3. Selecting the source size and mounting height
  4. Selecting Lumina ire type
  5. Determining Lumina ire spacing and location
  6. Checking for design accuracy/ adequacy with either 2,100 lumens to 8,400 Lumens, which are equivalent to 150 W and 450 W sodium light bulbs respectively.

Facilities analysis (FA) sites survey is the most important aspect of an engineering design/project. If you do not perform a thorough facilities analysis (FA), the project of installation of solar powered street and roadway lightings, installed according to the facilities analysis (FA), might never work properly, and government could spend millions of Naira on hardware that doesn’t do the intended job.

We will conduct Facilities Analysis (FA) which will enable us recommend to the government utility an adequate luminance values and uniformity ratios for Road Classification

Facilities analysis will be used for Roadway lighting designs bearing in mind:

     [a] Vertical Light Distribution

     [b] Lateral Light Distribution.

     [c] Control of Distribution Above maximum candle power.

     [d] Selection of mounting height.

     [e] Light system Depreciation,

     [f] Co-efficient of utilization.

     [g] Luminary spacing.

C. INVERTER SYSTEM:

An Inverter is a device that changes direct current (DC) into alternating current (AC). For example, that part of a UPS that converts the battery DC output to AC. A power inverter changes DC power from a battery into conventional AC power that you can use to operate all kinds of devices. The inverter needs electricity/ standby generator to charge up its batteries when they discharge. An inverter serves as a back up to electricity.

For example if Power holding company of Nigeria gives light in a building for about 12 hours in a day, an inverter can be installed in that building to back up the remaining 12 hours. An inverter has the following features and advantages:

Features & Advantages:

-Automatically switches from mains power to inverter power and vice versa
