The Potable Solar Panel – How does it Work?
There are two types: Photovoltaic and Thermal Portable Solar Panel. Photovoltaic panels produce electricity using such light where Thermal Solar panel produces electricity using the heat.
The cells of Photovoltaic panels are made with two layers of silicon. When sunlight hit the surface, photos create an electric field between both layers which is channeled with metallic strips and sent to the battery (for storage or use).
For better efficiency, connect the panel with a charge controller and regulation power output.
How Much Energy can a Single Portable Solar Panel Produce?
The output limit of a portable solar panel depends on the following three qualities: • Size • Efficiency • Sunlight Exposure.
The regular output of a solar panel in Standard Test Conditions. Is between 210-320 watts. However, these panels have a bit lower output as compared to the mentioned rating. You need to consider who many hours the panel will be exposed to sunlight as shade and clouds affect its power output.
The average household energy input is 30 kilowatt an hour. You can expect to meet 5-10% of your household demand with one solar panel. However, these devices are very useful during camping and outdoor trips.
They are very efficient for outdoor use as you don’t have drastic power demands. Following are a few things you can power using a portable solar panel :
• Charge your Smartphone.
• Power LED Lights and even a mini-fridge (using 120-watt panel).
• Power up the basic amenities of RV (160-Watt Panel).
How to Buy a Portable Solar Panel?
When you buy a portable solar panel, consider the following qualities:
Solar Cells.
There are two types of solar cells, monocrystalline and polycrystalline. Monocrystalline panels are the superior breed as they are made with high-quality pure silicone. This improves their durability and performance. These panels are more expensive and last longer compared to polycrystalline.
Polycrystalline panels are more affordable. They stand out thanks to their Dark Blue Color. Polycrystalline panels are made by melting fragments of silicone. This process makes these panels lightweight and portable but hinders their efficiency.
These panels are easy to fold or roll. Their power output is under 20%, but they can be easily installed on curved surfaces.
To make a smart investment with Solar panels, you must understand their specs. Yes, you should know the basics to compared different panels.
• Find Manufacture date because aging costs efficiency
• Buy panels with IEC 61215 Stamp. This stamp indicates the panel can stand to survive harsh weather
• ISO 14001 compliant panels are environmentally friendly and offer better power output
• Consider power ratings with maximum nominal power, voltage, and amperage at max output
• Check weight and dimensions
• See how long warranty covers repairs and defaults
• Consider salt and ammonia resistance if you are close to a beach
• Look for the durable frame as it adds strength to the whole panel
• See performance rating at low lightening
• See the number of cells and busbars
• Check STC Rating and module efficiency to see how well the panel performs under ideal conditions
