Laptops, mobile phones and all other gadgets that we use every day require constant charging. Most people charge their laptops at least twice a day. While a fully charged laptop can last for 4-5 hours, it often doesn’t, leaving you in a lurch. However, there is an alternative. You can buy a portable solar panel for laptop charging.

First, let us clear some of the most basic doubts about using solar panels for laptop charging before we move on to the buying guide.

Frequently Asked Questions about Solar Laptop Charging

1.   Can solar panels be used to charge laptops?

Yes, solar panels can be used to charge laptops. Small solar panels the size of power banks are a popular replacement for chargers. However, they’re popular for mobile phone charging and aren’t efficient for laptop charging. Instead, you can opt to install a rooftop solar system in your home specifically for laptop charging. Or, you can also buy a portable, medium-sized solar panel to charge your laptop.

2.   How can solar panels be connected to your laptop?

While it isn’t possible to connect a solar panel directly to your laptop, you can get a solar system for laptop charging. This would require a solar panel that connects to an inverter battery. You can then connect your laptop directly to this inverter or battery to charge your laptop.

3.   How many solar panels are required to charge one laptop?

The number of solar panels varies from model to model. A standard laptop requires 200 Wh (watt-hours) to 400 Wh. A single solar panel has a 100 Wh to 300 Wh charging capacity. Therefore, you will require one to two solar panels to charge your laptop. You can also opt to buy a portable solar power station customized for your laptop.

4.   Which components will you require to connect your solar panel to a laptop?

If you have bought a solar panel for laptop charging, you will require the following components:

  1. Batteries and inverters
  2. Charge controllers
  3. DC wires
  4. Adapters

Adapters are one of the basic requirements in this list and change from model to model. HP, Dell and Mac products often require model-specific adapters to connect solar system

5.   Do I have to buy all these components individually?

Thankfully, the answer is no!

You don’t need to buy each product and ask a technician to install the system for you. Instead, you can opt to buy a portable solar power station. This product comes with all the components you will require. All you need to do is find a sunny spot to charge the laptop!

6.   How long does it take to charge the laptop?

The charging time depends entirely on the size of your laptop’s battery and the capacity of your solar panel. Furthermore, the compatibility of your laptop and solar panel also affect your charging time. It can take anywhere from 2 hours to 10 hours.

Solar panels have become popular because they are an efficient, clean source of energy. Installing a solar panel for laptop charging is one of the best ways to reduce your carbon footprint. Now that we’ve answered your questions about solar panels for laptops, let’s understand how to find the right system.

How to find the solar panel perfect for your laptop?

You can find the right solar panel for charging your laptop in six simple steps. Ideally, these steps should be followed for any solar product that you buy.

Step 1: Understand your laptop requirements.

The first thing to do before you start searching for solar panel prices is to understand your laptop requirements. Each model has a different power requirement. You can find your laptop’s voltage requirement on the underside of your laptop. You can also find this information on your laptop’s adapter.

What to do if you can’t find laptop stickers?

If you’re using a laptop with no visible stickers or faded stickers, you can look up the power requirements online. Find the model number on your laptop, visit the manufacturer website and input the information. You can also contact customer care to find out more details.

Step 2: Understand the types of solar panels.

There are three ways you can get a solar panel for laptop charging:

  1. You can install a rooftop solar system and use it to charge your laptop.
  2. You can buy a small, portable solar charger.
  3. You can buy a portable power station or generator.

We recommend option #3: the portable power generator. This product is generally the size of your laptop. It is customized specially for laptop charging and includes two solar panels. Furthermore, manufacturers like Loom Solar also include all the other components that you need: wires, adapters, charge controllers, etc. All you need to do is connect the laptop to the generator and it will start charging.

Step 3: Do thorough online research.

Online research is one of the best ways to find brands and manufacturers. Review blogs that focus on solar or renewable energy products are a gold mine of information. Reading these will also help you find the names of popular solar manufacturers in the area. You can then search through their online stores or website to find a product that suits you.

Step 4: Select a product.

Once you’ve found appropriate blogs or narrowed down the list of products, you should check the compatibility. Is the solar system you choose compatible with Dell laptops? Or is it good only for HP products? If you can’t find the required information on the website, reach out to individual manufacturers with queries. When you buy a solar panel for home or laptop charging, it can easily last for 10-15 years. So, before you invest, be sure it’s compatible with your system.

Step 5: Read online reviews.

Most of us are used to reading online reviews for all online products. However, for solar products it’s much more important to read these. A solar panel can last up to 25 years with proper maintenance which means you want to be sure it’s good. Read reviews on marketplaces like Amazon, eBay as well as on the manufacturer’s website. We also recommend going through 2-3 review blogs that focus on the pros and cons of the product.

Step 6: Buy the product.

Solar panels for laptop charging can be bought online, which means you may not have to go to a shop. However, various manufacturers have shops or channel partners who sell their products. Once you’ve decided on the product, search for which option suits you best.


Finding a solar system to charge your laptop is as simple as finding any product. These systems require low maintenance, are cost-effective and can easily provide you with the energy backup you need. Investing in a portable solar power station is the perfect way to get ahead of any last-minute disasters. They are portable, lightweight and can be used when you’re travelling. With all the advantages of solar energy behind them, you should start searching for your solar panel for laptop charging now!
