You are considering installing a photovoltaic (PV) system on the roof of your one-storey home. Discuss four (4) factors that need to be taken into consideration with the installation of a PV system for providing electrical power to the home.
1. Amount of energy needed to power your house: It is very important to know average electricity consumption of your household to assess how many panels will be sufficient to provide the whole house with electricity.
2. The amount of direct sunlight is very crucial factor that will assess number and type of panels you should use. Of course, the main factor that impacts this is the region you live in, but tall buildings and trees can also seriously affect your panel’s sun exposure. Different panels have different reactions to shadow – some reduce the output while some shut down entirely. The more hours your panels will be exposed to full sunlight, the more efficiently energy will be produced.
3. How do you connect to the grid: In addition to the structure and shape of your roof, you also need to consider how you are going to connect your solar power system to the grid.
4. Don’t forget about maintenance: Installing solar panels require you to create holes in the roof. If these holes are not created or sealed properly, you will damage your roof and cause leaks. Keeping your solar panels working and your roof in good condition is all about establishing proper maintenance procedures
5. Wiring Problems: This is a job that requires you to work with electrical elements. If setup incorrectly, you can generate electricity shocks that are harmful to you and everyone around you. Always consult an electrician for any electric work.
