A solar-powered laptop is an innovative technology that makes its power independent of AC outlets. Powerful batteries are attached to the laptop and connected to solar panels. These solar panels receive sunshine and convert their energy into electricity. When this solar-powered laptop is equipped with a satellite link GPS or any other wireless internet access, it becomes a fully independent workstation you can take anywhere without any network or power issues.
Solar-powered laptops may work in different mechanisms with solar panels attached to the computer or detachable solar batteries that can be charged with solar panels. So, you need to choose the best option according to your requirements.
What is A Solar Powered Laptop
Like any other solar-powered device, a laptop comprises solar panels, an inverter, and batteries. Solar panels are the most critical component of a solar computer because they receive sunlight and convert it into electricity.
A futuristic solar-powered laptop design uses photovoltaic cells embedded on the top of the notebook. These cells obtain energy from the sunlight and use it to power the laptop battery. However, it is important to consider the charging hours of the battery and whether it offers pass-through charging. Pass-through charging means the battery is charged, and the computer uses the energy simultaneously. We also need a cooling mechanism for the laptop because placing it in direct sunlight may adversely affect the hardware.

Solar Powered Laptop FAQs
1. What size of solar generator do I need to power a laptop?
The average power requirement of laptops is in the range of 65 to 200 watts. So, you can support it with small Jackery solar generators like Jackery Solar Generator 600 Plus, Jackery Solar Generator 300 Plus, and Jackery Solar Generator 240 v2. You can calculate the working hours of all solar generators by yourself if you know the capacity of the generator and the watt requirement of your laptop.
For example, if we take Jackery Solar Generator 1000 Plus with a capacity of 1264Wh.
Working time = 1264Wh * 0.85 / operating wattage of your laptop.
As we discussed already, we take only 85% of the capacity to incorporate power loss during operation. Hence, multiplication with 0.85 in the above equation.
If your laptop needs 65 watts, then;
Working time = 1264Wh * 0.85 / 65 W = 16.5 hours.
2. What to consider when running a laptop on solar power?
The main factors that help you in choosing and running a laptop on solar power are;
- The wattage of your laptop.
- The safety of your equipment in case of fluctuation.
- The mechanism to use solar power, i.e., you are using a solar-powered laptop,solar-powered laptop charger, or a solar generator.
- The working hours of your laptop.
3. How many solar panels do I need to run my laptop?
It is important to know your laptop's power consumption to calculate the number of required solar panels. So, how many solar panels to power a laptop?
For most laptops, 2 to 3 Jackery solar panels with a capacity of 200 watts are good options. We recommend the Jackery solar panels because they offer the highest 23.7% efficiency. You can pair them with the Jackery solar generators to run your equipment and save solar power in batteries.
4. How to build a DIY solar laptop charger?
-
Acquire a portable solar panel system, depending on your requirements.
-
Choose a battery pack that is compatible with your laptop.
-
Connect your solar panel with the battery pack and then the battery pack to your laptop.
a. Connect the output/positive terminal of the solar panel system with the input/positive terminal of the battery pack.
b. Connect the output/negative terminal of the solar panel system with the negative input terminal of your battery pack.
-
Voila! Your solar laptop charger is ready.
Final Thoughts
Solar-powered laptops aim to harness solar power to power your laptop without needing AC outlet charging. However, some limitations include temperature control, using the laptop in sunlight, and battery safety. These limitations are the reasons why solar-powered laptops are not very popular. However, you can use solar power to run your computer safely using Jackery solar generators because they are cost-effective, safe, and reliable. Since they offer pass-through charging, you can run your laptop and charge your generator simultaneously. Also, they have temperature sensors, and the primary cells and inverters are equipped with an independent air duct design. These features make these generators very safe.
