What are the main components of a solar energy system that comes to your mind when you think of solar energy? Our guess is: you’re definitely thinking of some of these.

There is really so much to a solar system than the panels. The solar system has multiple components but we shall be discussing the key ones.

There are four key components of a solar energy which are: the panels, inverter, battery and racking.



The panels are the most visible components of the solar system. In other words, they are the face of solar. Wherever you see panels, solar comes to mind right away. And just by the positioning of the panels alone, you will know which house is using solar in your street.

How Panels Works: panels generate DC electricity as sunlight. Contrary to majority view that it’s the heat that generates electricity, it’s the sunlight itself that actually does. As matter of fact, over heated panels can be less efficient, similar to a computer overheating. There are lots of solar panels in the market by various brands. So, when choosing, you need to know exactly what you want and what to get. Our team of professionals at Vesselnet Solar will always assist when you contact us.

There are majorly two types of panels which are the monocrystalline  and the polycrystalline panels. On average, solar panels can last between 25 years to 30 years.

Monocrystalline panels is made up of singular large crystals and dark in colour.

Polycrystalline panels are made up of multiple smaller crystals and it’s usually of a light or blue colour.how long do solar panels last?


The major function of inverter is to convert the DC electricity to 240V AC electricity for safe usage. Inverter never stop working throughout the life time of the solar system since it’s always converting DC to AC electricity. This also means that, it’s the component that will mostly develop a fault. This is why you need to choose the best brand. Usually, average life span of an inverter is 10 years.


There are major two types of inverter which are string inverter and Microinverters.


String Inverter: these are installed unto a wall usually in a shaded area and converts the energy from a string of panels into AC electricity for home usage.

Microinverters: they are installed on the back of each of the panels. This allows for energy of the panels to exist independently.



As we all know, batteries are for storage. In this case, they are used to store solar energy during the day to be used throughout the night. With batteries, your solar system can run for 24 hours due to energy saved during day from solar light. Batteries are very important and quality shouldn’t be compromised. This is why, here at Vesselnet Solar, we have some of the best battery with 3 Years warranty.

The rack is what attaches the panels to the roof. Quality should be the watch word when buying solar system rack. A high quality racks is needed to ensure maximum safety of the panels on the roof top.
