What is a “Solar Energy Generation System?”

A solar energy generation system utilizes solar irradiation and allied equipment to generate electrical energy for use in homes, offices, factories, school, etc. A solar energy generation system is made up of solar modules, solar modules mounting structures, solar inverters, cables and safety features, such as overvoltage protection. Solar technology is also known as photovoltaic (PV).

Roof mounting solar arrays in Ghana have to be installed south-facing. Alternatively an East- and/or West-facing roof could be used in combination. In some cases (e.g. solar powered water pump on farms) solar modules are ground mounted.

How does a “Solar Energy Generation System” work?

The output power (Direct Current, DC) generated by the solar modules is converted into Alternating Current (230 AC) with the help of a solar inverter, which is connected to the solar modules by UV-resistant cables.

The system is configured in such a way, that the electrical current, converted by the solar inverter, is transferred directly to the electricity consumers such as light bulbs, fridges, computers, via the electrical distribution panel at the home, office, hospital, factory etc.

The advantages of a “Solar Energy Generation System”

The biggest advantage of using solar power is the reduction of the electricity bill. This will be achieved by replacing every unit of power delivered by the public grid (ECG or NEDco) with power from the solar system.

Solar electricity will always be consumed preferentially, so that the purchase of electricity from the public grid can be reduced accordingly and therewith the costs.

By scaling up the solar system the electricity bill can be brought to “Zero”.
