Things To Consider When Running A Computer On Solar Power

Things To Consider When Running A Computer On Solar Power

With the right setup and positioning, it is now possible to run your computer on solar power. The more exposed your solar panel is to direct sunlight, it will provide you with an interrupted power supply. Since there are different types of computers available in the market (desktop, laptop, palmtop, macs), they all have additional energy requirements. Also, the power consumption tends to vary from one system to another. 

Therefore, here are few things which you should consider before you switch over to solar-powered computing.

1. Power Consumption

As we mentioned above, the power consumption tends to vary from system to system. Every type of computer in the market needs a different amount of power. For example, a laptop uses comparatively less power than a desktop. If you need to switch to solar computing, you will first need to calculate the overall energy consumption. A standard computer needs between 200-300 Wh per hour, whereas a high-end gaming PC will need between 400-500 Wh every hour. Therefore, it is essential to consider your system’s power before switching over to solar-powered computing. 

It is essential to know the power consumption of your laptop as it helps calculate the number of solar panels required to recharge the laptop. So, how many solar panels to power a computer? For most laptops, 2 solar panels with a capacity of 300 watts should be enough to charge your laptop. This has been calculated by keeping the power usage of the laptop in a range of 60 – 320 watts.

If you have a desktop, you may also need a keyboard. Check out these solar keyboards to add to your eco friendly work pack.

2. Battery Power

Another critical factor to consider is battery power. The capacity of your battery ultimately decides how long you can run your system before finally running out of power.
