It was really great and adventurous for me today. 
Here are some of the pictures of the installation.
The inverter and charge controller. The 1.5kva inverter would convert the DC (direct current) from the battery to AC (alternating current) so as to power the AC appliances in the house. It also converts the AC form the grid and fuel generator to DC so as to charge the battery. The charge controller on the other hand makes sure that the battery does not get overcharged. It cuts off further supply of current from the solar panels when the battery is fully charged.
The DC cables from the battery (the thick black and green) are connected to the positive and negative terminal of the inverter while the cables for all the appliances put together (the thin red and black) are also connected.
The DC cables that go to the inverter and the charge controller are connected to the right terminals of the battery.
After the connection of the battery to the inverter and charge controller had been done, the charge controller was able to detect the voltage of the battery as 11.4 volts which ideally should be 11.9 or 12 volts for a new battery.
After those connections, the next task done was to mount the panel onto the roof. It was quite challenging as the roof was steep and hot because the sun was intense.
After the successful mounting of the panels on the roof, the DC cables from the charge controllers were connected to the right terminals of the panels. Each of the solar panels is 100watts and the their combination will sufficiently charge the battery and when one more battery is added in a few months from now.
After the set up was complete, two bulbs and a fan were switched on to test if the connections were rightly done and they when they came on we were delighted of the successful installation.
With the solar system having been successfully installed in the housed, the owner would enjoy savings from the reduced electricity bill from the grid companies and not buying fuel very often to power his fuel generator- thereby reducing noise and air pollution to the environment.
Overall, it was pure delight and joy that the installation was successful. It was also a great feeling that we had been able to contribute on our own little way to the sustainability of the environment by promoting renewable energy.
It would be a very huge step that the costs of the solar materials are subsidised so that more people can enjoy electricity where access to grid is not available.
