1. What is Solar Electricity or Photovoltaic (PV)?

Solar electricity is generated from sunlight. Photovoltaic is a technical term, which refers to a technology whereby sun light is converted into electricity. The process of conversion is achieved by use of devices called solar cells, which in most cases people call them solar panels.

2. What solar electricity cannot do?

Use of Solar PV technology is not economical for highenergy consuming appliances such as electric cookers, iron, and three phase machines. In this case you are advised to use other sources of energy such as grid electricity and diesel Generators.

3. How long will a solar system last?

A solar module will last for more than 20 years, a charge controller for 10 years, lights for 7 years (tubes might be replaced after 2 years), battery

4. How much does a solar system cost?

Cost of a solar system will depend on energy demand of specific system user. Energy demand is determined by power consumptions of appliances to be used in your system and the duration you use them every day.

5. Why use a solar system and not petrol generator?

Solar system’s major investment is done once and maintenance costs are not significant (less than 2% of system cost per year) as there are no any moving parts. Petrol generators might have lower initial investment cost as compared to that of a solar system but it requires high operation costs including fuel, repair and maintenance.
