2. INTRODUCTION. Solar energy is an efficient alternative energy source.
Solar energy also being renewable promises a lifelong supply of energy.

3. PRESENT DAY APPLICATION.
Street lighting.
Load powering.
Power source for homes.
Back-up for accidental light-outs in Hospitals.

4. STREET LIGHTING.
Illumination stands today as one of the factors for determining the level of development of an environment.
Solar-powered street lighting as a method of illumination on the streets of Nigeria is a major step forward.
This will contribute positively to the development of this nation.

5. “THE STANDALONE SYSTEM”.
This system consists of the following:
Battery
Solar panel module(s)
Solar charge controller - needed to power the light fixture all attached to the luminaire forming a single unit.

6. CHALLENGES OF THE STANDALONE SYSTEM
It is difficult to maintain.
Weight of battery affects the poles.
Susceptible to harsh weather.

7. PRPOPSED CORRECTIVE SYSTEM
The proposed system sums up the power requirements of all the lighting fixtures and supplies them together.
​The luminaires in this system are all connected in series.
​ The power requirement of the whole set up will be calculated and catered for by a battery bank.

8. PRPOPSED CORRECTIVE SYSTEM
The battery bank will be able to supply the needed power as the number of batteries to supply the said power will be connected together to supply the loads. Connected to the battery bank will be an array of solar panels capable of charging the battery bank effectively and efficiently. This system like the standalone will also have solar panel module(s), solar charge controller(s), batteries and inverter(s) if necessary.

9. PRPOPSED CORRECTIVE SYSTEM
​The solar charge controller will ensure that the right amount of charge is flowing to the battery at every given time and will also ensure that optimum amount of charge is always available in the battery at all times.
​The inverter can be connected to the battery bank to convert the DC stored in the batteries to AC for AC powered loads.

11. BENEFITS OF THE PROPOSED SYSTEM
Maintaining a setup with the standalone system is very stressful.
The proposed system has an added advantage of being very attractive.
The proposed system will have a proper shelter for the units in the system to prevent the harsh effects of weather changes.

12. CONCLUSION
The proposed system is very reliable and a viable replacement for the standalone system.
