Electricity plays a vital role in the wellbeing of human beings. There are very many sources of electricity today. Some of these sources are unfriendly to the environment while others are friendly.

Over the years man has been trying to invent clean and more efficient energy sources because global warming is on the rise. One of the best innovations that had happened to the world is the invention of solar energy.

In this article, you will learn some of the key factors to consider before installing a solar energy system in your home. Keep reading the guidelines below.

Efficiency

The first aspect to look at before making a decision on installing a new energy panel system is the energy efficiency of the solar panel system. Make sure that you invest in a high-efficiency solar panel. When we are talking about the solar panel efficiency, we mean the ratio in percentage of the energy from the sun.

For instance, if your solar panel can capture half of the energy supplied by the sun, then the panel efficiency is 50%. Now, in reality, most conventional solar panels have efficiencies ranging from 12% up to over 21%. In this case, you can choose to buy a solar panel with an energy efficiency of about 15% and above.

You should understand that the more the efficiency of the panels, the more the watts you get. Although high-efficiency solar panels are costly they are worth the money. If you want to install a solar energy system as an alternative to the grid energy, then you can invest in low-efficiency panels. However, for those who want to install a solar energy system as the sole source of electricity, it is vital to invest in a high-efficiency solar panel.
