Portable Power Stations VS DIY
What are the advantages of a diy solar systems over off the shelf portable power stations. Is it just price? Or are there other advantages?
Solar energy is a renewable energy source that utilizes light and heat from solar radiation, which has the advantages of non-pollution, non-depletion and wide distribution, and is one of the important energy sources for sustainable development in the future. However, the utilization rate of solar energy is affected by many factors, such as geographical location, climatic conditions, and equipment performance. In a world that is increasingly focused on sustainability and self-sufficiency, the choice of DIY solar systems and commercial portable power stations has become an important consideration for individuals who are looking for reliable and environmentally friendly energy solutions.
There are many portable solar power stations on the market today that can power a variety of devices, but they are more expensive, have less capacity, and are less flexible. Some people will choose to make their own solar systems to save money, increase efficiency, have fun and spread the idea of environmental protection. This article is going to discuss the differences and advantages and disadvantages of homemade solar power systems and off-the-shelf portable power stations, as well as the steps and considerations on how to make your own solar power system.
1. Composition and working principle of homemade solar energy system
Homemade solar systems are generally categorized into two types: off-grid and grid-connected:
Off-grid solar systems mainly consist of solar panels, inverters, batteries, controllers, etc., which can provide you with independent power where there is no grid.
Grid-connected solar system mainly consists of solar panels, inverters, which can save your electricity bill or get subsidized by connecting the electricity converted from solar energy to the grid.
Main Component
- Solar panel: It is the core component of a solar system that converts sunlight into direct current electricity. The performance and quality of the solar panel determines the efficiency and longevity of the solar system in generating electricity. You can choose different types of solar panels such as crystalline silicon, thin film, copper oxide, etc. depending on your space and budget.
- Inverter: It is an important part of the solar system which converts DC power into AC power for your home appliances. The type and performance of the inverter determines the output voltage and frequency of the solar system and how well it matches with the grid. You can choose different types of inverters, such as off-grid inverter, grid-tie inverter, micro-inverter and so on, according to your electricity needs and grid conditions.
- Battery: It is a necessary component of an off-grid solar system, which stores the excess power generated by the solar panels for use at night or on cloudy or rainy days. The capacity and performance of the battery determines the energy storage capacity and stability of the solar system. You can choose different battery types, such as lead-acid batteries, lithium batteries, nickel-metal hydride batteries, etc., according to your power needs and environmental conditions.
- Controller: It is the key component of off-grid solar system, which can control the charging and discharging of the battery by the solar panel to protect the life and safety of the battery. The type and performance of the controller determines the charging and discharging efficiency and management of the solar system. You can choose different controller types, such as PWM controller, MPPT controller, etc., according to your battery type and system size.
2. Features and functions of off-the-shelf portable power stations
An off-the-shelf portable power station is a type of mobile power supply that can provide AC or DC power to various electronic devices, which usually consists of lithium-ion batteries or lithium iron phosphate batteries that can be recharged via the grid, solar power, or automobile.
The features and functions of off-the-shelf portable power stations mainly depend on their capacity, output, input, charging method, and other parameters, and different brands and models may have different performance and prices. Below are some common features and functions:
- Size and weight: The size and weight of off-the-shelf portable power stations are related to their capacity and battery type; in general, the larger the capacity, the larger the size and weight. For example, the Niuess NE-1200 Portable Power Station has a capacity of 1228Wh, measures 15.8 x 8.7 x 11.7 inches, and weighs 39.6 pounds. The ETEKWARE PA-1200 power station, on the other hand, has a capacity of 1200Wh, measures 12.6 x 7.9 x 8.7 inches and weighs 15.4 pounds.
- Capacity and Lifespan: The capacity and lifespan of off-the-shelf portable power stations determines how long they can power how many devices, and is generally expressed in watt-hours (Wh) or amp-hours (Ah). The higher the capacity, the longer the life. For example, the Niuess NE-1200 Portable Power Station can power a 150W refrigerator for 8 hours or charge a 60W laptop 20 times. The ETEKWARE PA-1200 power station can power a 100W TV for 12 hours or a 50W fan for 24 hours.
- Outputs and inputs: The outputs and inputs of off-the-shelf portable power stations determine the type and number of devices they can connect and charge, and typically include AC outlets, DC ports, USB ports, etc. Different outputs and inputs have different voltages and currents. For example, the Niuess NE-1200 Portable Power Station has 2 AC sockets (110V/1200W), 2 DC ports (12V/10A), 2 USB-C ports (100W Max), 4 USB-A ports (5V/12W Max), and 1 car power outlet (12V/10A). While the ETEKWARE PA-1200 station has 2 AC outlets (110V/1000W), 2 DC ports (12V/10A), 1 USB-C port (45W PD), 2 USB-A ports (5V/3A), 1 car power outlet (12V/10A).
- Charging method: The charging method of off-the-shelf portable power stations determines the route by which they can recover their power, typically grid, solar or automotive, with different charging methods having different charging times and efficiencies. For example, the Niuess NE-1200 portable power station can be charged for 2 hours via the grid, 2.5 hours via solar and 5 hours via car. The ETEKWARE PA-1200 station can be charged for 6 hours from the grid, 8 hours from solar and 10 hours from a car.

There are significant differences between homemade solar systems and portable power stations in terms of cost, efficiency, reliability, environmental friendliness, safety and flexibility. Homemade solar systems are typically lower in cost, have efficiencies that depend on the quality of materials and assembly, are highly customizable, and are environmentally friendly. Portable power stations, however, offer higher overall efficiency and stability, but are correspondingly more costly and less flexible. Choosing the right option should be based on individual needs, taking all factors into account to achieve the optimal energy solution.
Conclusion
Overall, homemade solar systems and off-the-shelf portable power stations have their own advantages and disadvantages, depending on individual needs and priorities. Homemade solar systems are superior in terms of cost, environmental friendliness, and flexibility for individuals who are looking for sustainability, are open to customization, and have some technical skills. However, off-the-shelf portable power stations may be more convenient for those who are focused on overall efficiency, portability and don't want to get too involved in the technical details.
There is no one option that is the absolute best choice, but rather one that suits different purposes and needs. With enough time and technical knowledge, a homemade solar system can be a fun and rewarding project. However, for those looking for convenience and overall performance, a portable power station may be a more suitable option. Whichever option is chosen, it should be researched carefully to ensure that the final energy solution meets individual needs and fulfills long-term expectations.
