Ø UP TIME REQUIREMENT – Every telecom tower MUST have continuous energy 24hours per day, every day. The Mobile Network Operators require UP-TIME of 99.95%.

Ø PROVEN 100% UP TIME - The Apollo Solar systems have proven UP-TIME at 100%. No other manufacturer can match that.

Ø 10 YEARS OF FIELD EXERIENCE – The Apollo Solar T80HV MPPT Charge Controller, the heart of the Energy System, has been manufactured since 2006. There are many thousands running throughout the World with great reliability.

IIAN TECH= Reliable Continuous Energy

ousands running throughout the World with great reliability.

Ø PROVEN TRACK RECORD IN AFRICA – The climates and logistics in Africa are challenging for remote electronic systems. The Apollo Solar Telecom Energy Systems are tested and proven all over Africa.

Ø EXPERIENCE AND FEEDBACK – Apollo watches the performance of our installationsusing our Remote Monitoring software. We have the feedback of the performance overyears on hundreds of sites so we can be certain about Battery and PV Array sizing.

Apollo is the Leader in Solar Energy InstallationsIIAN TECH and Apollo Solar has deployed more Pure Solar systems than any other company!

Pure Solar sites must be ultra-reliable since there is no generator for back up.Many sites are in desert or jungle climates. The ma-ps show some of our 700 locations in Africa andMa-dagascar.

Components of the IIAN TECH Hybrid Energy System

1The Tower

runs from a Battery 24/7

2We Recharge the

Battery using Free Energy from the Sun

3The IIAN TECH Cabinet includesall the electronics to control the Charging and Discharging with Remote Monitoring

On rainy days, we Recharge the battery with a Diesel Generator.

Only if the room for the PV array is limited, a Diesel Generator fills in the difference.


With Solar added, we run the generator at 3 to 4 times better efficiency than DG only.Ø A typical site using diesel generators has 2 generators that are 12kW to 24kW each.Ø The avg tower load is 2kW, so the generators are running at 8% to 17% of full power.Ø From the chart below, we see that the fuel consumption at 10% of full power is about

1.2 Liters per kWh.Ø We add solar and batteries and run the Generator at 100% full power so the fuel

consumption is only 0.3 Liters per kWh – a full 4 times improvement.

Ø OPERATING EXPENSE – Energy created by Diesel Generators is 50% of the costs to operating a tower. Solar can cut that OPEX to close to zero.

Ø THE REASON TO USE SOLAR –Diesel Fuel costs, including delivery and theft alongwith the costs of maintaining and replacing the diesel generators can be eliminated.

Ø RESPONSIBLE ENERGY GENERATION – The cost to the environment of the greenhouse gases from continuous diesel consumption at every site is a large problem.

IIAN TECH Systems Lower OPEX at Minimum CAPEX

greenhouse gases from continuous diesel consumption at every site is a large problem. Each IIAN TECH 2kW Pure Solar system avoids about 4 tons of CO2 every month.

Ø THE CAPITAL COST OF SOLAR – IIAN TECH systems maximize the life of thebattery which reduces the long term capital costs.

Ø TOTAL COST OF OWNERSHIP – IIAN TECH Energy System can pay for itself in 12to 24 months, depending on the local costs of diesel fuel.

Control of the generator and our Remote Monitoring was created by our engineers.

IIAN TECH– Key Differentiators

Control of the generator and our Remote Monitoring was created by our engineers.

4. COMPLETE SOLUTION – Our EPC partners are the best in the business. Together, we provide a single point of responsibility from design through installation, commissioningto operating and long term maintenance. Our customers are free from the problems of multiple vendors with competitive maintenance providers avoiding responsibility.

5. FINANCING OPTIONS – Our financial partners can often provide long term paymentplans for the credit worthy customer.


Ø COST – The battery can often be 50% of the cost of the energy system. Proper sizing and selection of the battery type makes a big difference in the cost of your energy.

Ø CAPACITY – The price of the battery is based on its rated capacity. Our Charge Controllersmake sure 100% of the rated capacity is used effectively.

We measure the battery voltage at the battery terminals continuously for accurate char-ging. When the battery needs equalization, we provide that automatically.

Ø LIFETIME – If the battery is not charged properly, the lifetime will be reduced. Our Charge Controllers optimize the battery life. The voltage and temperature are monitored accurately and charging voltages are adjusted automatically.

These are Battery Based Systems

accurately and charging voltages are adjusted automatically.

Ø SIZING – We use a separate cabinet for the batteries so the size of battery bank can be optimized for each site.

Ø EXPERIENCE AND FEEDBACK – Our monitors the sites that are installed using ourelectronics. We have the feedback of the performance over years on hundreds of sites sowe can be certain with battery or PV array sizing to optimize cost and perform-ance.

Ø CELL CHEMISTRY – The T80HV is designed to charge all available battery types including: AGM, GEL and Flooded Lead-Acid, Ni-Cad, Nickel-Iron and Lithium Ion including LiFePO4.As Lithium Ion batteries become more cost effective, we are ready to use them.

IIAN TECH Solar Hybrid Power Systems

The Gen 4 PVT Systems include all of the electronics in a single cabinet for easy installation.

The cabinets are powder coated steel and sealed to meet IP65 and are intended to be outdoors, typically in the shade, under the PV array.

The cabinet is 1000mm wide x 300mm deep x 1200mm tall. It is shown The cabinet is 1000mm wide x 300mm deep x 1200mm tall. It is shown here with 450mm legs. They can also be hung from the ground-mounted PV support system.

All of the cables exit from the bottom using water- proof glands. The cables can be covered in optional rodent-proof metallic braded shields.

Multiple cabinets can be installed side by side, or back to back as shownhere.

Let IIAN TECH quote systems for you….We just need to have a few facts for your specific tower sites:

1. DC Load of the BTS in kW2. Cost of diesel fuel – including delivery charges to the remote sites3. Cost adder to compensate for fuel losses (slippage, theft, etc.)4. Size of the existing diesel generators in kW5. Cost for periodic maintenance of the diesel generators

How to get the optimum OPEX / CAPEX mix

5. Cost for periodic maintenance of the diesel generators6. Approx location of the sites for solar irradiance calculations7. Any restriction on the size of a PV array in square meters of real estate8. Number of towers to be converted to Solar, or Solar/Diesel Hybrid

We will calculate the best choices of OPEX / CAPEX and present a proposalfor your specific needs.
