Installing solar panels can reduce your dependence on fossil fuels and reduce your greenhouse gas emissions. It can even reduce your electricity bills, saving you more money in the long run. It is, however, more important to install the right number of solar panels to run your house.

How Many Solar Panels Do I Need?
The number of solar panels you need depends on how much power you use in your home and the times of the day you will use your solar panels. Therefore, the number of solar panels you install should generate enough electricity to cover your house’s power usage.
What are the Factors to Consider?
If you have a freestanding house, your roof area can support the solar panels you need to power your house. However, an unusual pitch and more shaded sections can reduce the number of solar panels you can install on your roof. It is, therefore, important to make the most of the available space on your roof.
Size of Inverters
The solar panels generate direct electricity. You need an inverter to convert the direct current (DC) to alternating current (AC) since almost all house appliances use alternating current. The size of your inverter must, therefore, match the size of the solar PV array.
Orientation of the Solar Panels
Your solar panels should face north to maximise the amount of sunlight falling on them. You can talk to your installer to determine the best orientation for the solar panels on your roof. Once you determine the orientation, you can get enough solar panels to fit the available space.
