TASK 1
John has decided he wants to use Solar energy.
But because of the cost associated with it,
he wants to start with a Backup system
before divulging into Stand Alone System.
John is also working on the limited budget
of to 2kva system at most.

Here are the list of his appliance
10 Energy Saving Bulb (20w)
3 Standing Fan (50w)
1 Celling Fan (120w)
10 Phones (10w)
2 LCD TV (150w)
1 Decoder (30w)
1 Microwave (600w)
1 Air Condition (1000w)
1 Laptop (75w)

Based on his budget, John wants to know
His Energy consumption
Inverter size
Number of batteries

interesting....please go ahead op

TASK 2
John is impressed with the system.
But the backup time is to small.
In other to increase the back up time
We have to increase number of batteries.
John also use a petrol generator
To charge his battery when there is no power
From the national grid (PHCN)
John wants to spend 10 hours of charging the battery daily.
If he has an average of 4-6 hours of power from the grid daily

Question 1
How many batteries will be needed in order
To attain 24hrs supply.

Question 2
Configure the Batteries into series-parallel configuration

Use 200ah Battery rating.

TASK 3
1 years later, John wants to upgrade to Solar Panels
Petrol is scarce and Public power supply has dwindled
The cost of running petrol generator is expensive.
Because this is a Solar upgrade,
We are going to use the hybrid feauture for this task.


Question 1
Assuming a 5 hour power supply from national grid daily
How many panels and charge Controller Rating
will be needed to charge 6 Batteries of 12v 200ah

TASK 4
Edward built a 5 bedroom Duplex In a remote village
and wants to go completely off- grid.
He knows the project will cost him a lot,
So he is looking for a solar company that will
Finance his project for a period of 12 months.

List of Appliance
15 Energy Saving Bulb (20w)
5 Standing Fan (50w)
2 Celling Fan (120w)
4 LCD TV (150w)
15 Phones (10w)
1 Decoder (20w)
1 Fridge (150w)
1 Freezer (300w)
1 Microwave (600w)
1 Air Condition (1000w)
2 Laptop (75w)
1 Inkjet Printer (50w)
1 Electric Iron (1000w)
1/2 HP Water Pump (1500)





Question 1
Energy consumption
Inverter size
Number of batteries
Nos of Panels
Charge Controller Rating



Question 2
If after Energy Audit and costing
$20,000 is needed to purchase the system.
Edward only has $5,000 at the moment.
If the solar company is offering him 15℅ rate
How much is Edward expected to pay per month?

Bro good day. I think I might need your help asap as regards solar PV installations and everything that comes with it. My location is Lagos.

Can I mail you here?

Anticipating your response.

Thanks.
