With the growing environmental concerns of climate change and the decreasing prices of solar PV, solar energy is trending in many sectors, including but not limited to power homes and businesses. Also, portable solar solutions including portable solar chargers or solar phone chargers are trending with increasing awareness about renewable energy. This article attempts to explain five(5) benefits of using a solar phone charger:
- A solar phone charger is portable and uses clean energy to help you charge your electronic devices. Once you have selected your solar cell phone charger, whose cost can be estimated to range anywhere from $50 to $200 depending on the brand and features included, a solar phone charger is very portable as it can be carried anywhere to charge your cellphone. A solar-powered phone charger comes in handy, especially used during traveling or outdoor activities. Since it is portable during the day when there is sunshine you can use it in your picnics, hikes or when camping to use it to charge not only your cellphone but also your iPad, portable speaker, humidifier, etc.
- A lot of people especially in rural areas mostly in the developing world are not connected to the grid. As such, having solar chargers and other solar PV systems like solar panels and solar batteries are being used to produce power for both households and commercials helping to solve the energy access issue.
- A solar phone charger would probably be the main source of energy in off-grid areas to power cellphones. For instance, in Africa, around 640 million people don’t have access to a grid and where some people do have access to the electricity supply is unreliable and unstable. As a result, solar PV has become one of the main sources of energy to power homes and businesses using one of the most consistent and promising approaches to tackling this huge obstacle to energy access, that is, off-grid pay-as-you-go solar power model, now called PayGo.
- A solar phone charger uses solar energy – a renewable energy source. Even though energy from a solar charger might seem trivial or does not have an impact in terms of how much you can save when it comes to energy because cellphones or smartphones use a trivial amount of electricity. For instance, iPhone 5 uses 3.5KWh/year and costing about $0.41/year to charge them while Galaxy S III consumes 4.9 KWh/year at $0.5/year primarily because of the Galaxy’s larger battery. However, this might not impact you, but considering the aggregate impact (about 5 billion cellphones around the world) in terms of energy reduction from the grid and the increasing demand for mobile phones worldwide; your usage of the Sun’s energy to power your phone probably has an impact, if you look at it from a system’s perspective.
- A solar phone charger is one step to energy efficiency when you aggregate the number of cellphones from a system’s perspective. Currently, there are about 5 billion cellphones around the world according to GSM intelligence. Users for smartphones are expected to increase by 2023 to over 7 billion. Smartphones consume more energy depending on how many wireless data the device is using as well as the amount of power consumed in making those wireless connections. As a result, when not using energy from renewables, a solar phone charger can help in reducing your carbon footprint.
From a system’s perspective, electronic gadgets or even electric vehicles powered using solar power will have an impact in terms of greenhouse gas (GHG) emissions reduced while increasing the energy efficiency consumed in the long-term.
Some of the best solar phone chargers have been reviewed on Amazon. When looking for some of the best solar phone chargers, it is important to evaluate the number of devices that can be charged, the time it takes to charge, and overall durability when selecting a model.
