400 Watt Solar Panel FAQs
Efficiency is the ability of a solar panel to convert sunlight into electricity. The efficiency of a solar panel is usually expressed as a percentage of how much light energy is converted into electricity.
Standard 400 watt solar panels typically have an efficiency of between 18% and 22%. This means that they can convert about 18% to 22% of the sun’s rays into electricity.
Sungold 400w solar panels HP-D-400w have an efficiency of up to 22.%, which allows them to produce more electricity under the same light conditions, which provides electrical support for limited installation space or where there is a specific electrical energy requirement. As solar technology evolves and Sungold products are upgraded, even higher efficiency solar panels may be available in the future.
Installation and maintenance of traditional 400 watt solar panels requires some specialized knowledge and skills. However, Sungold HP-D-400W is very easy to install and maintain.
Simply unfold the solar panels and secure the mounting bracket, connect the energy storage and adjust the angle to start generating electricity.
Regular Cleaning: keep the surface of the solar panel clean, remove dust, dirt and weeds etc. regularly, which will help to improve the power generation efficiency of the panel.
Regular Inspection: Check the panels and brackets for looseness or damage every once in a while, and repair or replace them in time.
Prevent shadows: Ensure that shadows do not cover the panels in the surrounding environment, as even partial shadows can drastically reduce the power generation efficiency of the entire panel set.
Regularly check the power output: You can check the power output of the solar panel regularly through the inverter monitoring system or other power monitoring equipment to ensure its normal operation.
Different brands and models of 400wt solar panels may have different quality and durability, regular cleaning and maintenance is also key to keep your solar panels waterproof and durable, regular inspection and maintenance of your solar panels can ensure the long-term efficient operation of your solar panels.
The surface of Sungold 400wt solar panel HP-D-400w is covered with ETFE material, which is splash-proof. If you use the MC4 connector, the waterproof The whole product can be completely immersed in water without affecting the work of the product.
Sungold 400wt solar panel HP-D-400w has a 5 year warranty and a 10 year service life.
400 watt solar system can be used in different environments, but its performance and suitability may be affected by some factors. The following are some of the environments in which 400 watt solar system is suitable for use:
High sunlight areas: 400 watt solar panels are particularly suitable for use in high sunlight areas as this maximizes the power generation potential of the solar panels. The local sunlight is abundant and more electricity can be generated.
Homes with large roof or floor space: For homes with large roof or floor space, 400w solar panels can be relatively easy to install and set up to meet some or all of a home’s electricity needs.
Commercial and industrial applications: 400 watt solar systems are also suitable for commercial and industrial applications, especially for small to medium sized businesses where a system consisting of multiple solar panels can be installed on the roof or grounds.
Off-grid systems: If you are located in an area where there is no stable grid power, the 400 watt solar system can be used as an off-grid system to help you obtain an independent power supply.
Systems in parallel with the grid: For areas with stable grid power, 400 watt solar systems can be connected in parallel with the grid, backfeeding excess power through the grid, thus lowering the cost of electricity for your home or business.
The size of cable needed for 400 w solar panels depends on several factors, including the distance between the solar panels and the charge controller or inverter, as well as the amount of current (in amperage) produced by the solar panels.
To determine the proper cable size, consider the following factors:
Current: Find out the maximum current output of 400 w solar panels. The solar panel specifications or data sheet should have this information.
Distance: Measure the distance between the solar panels and the charge controller or inverter. This will help determine the voltage drop across the cable.
Cable Type: Select the type of cable suitable for the installation, e.g. copper conductor or aluminum conductor.
Voltage Drop: Calculate the voltage drop across the cable. Excessive voltage drop can lead to power loss and reduced efficiency, so it must be kept within acceptable limits.
Amperage: Ensure that the cable’s ampacity (current carrying capacity) is sufficient to handle the maximum current output of the solar panel.
Temperature Rating: Consider the temperature conditions of the installation area and select cables with an appropriate temperature rating.
For most residential solar installations using 400 watt solar panels, the appropriate cable size for short distances is usually between 10 AWG (U.S. wire gauge) and 12 AWG. However, for longer distances or higher current outputs, thicker cables and lower AWG values may be needed to minimize voltage drop.
Solar panels are typically required to meet a range of international certification standards and safety regulations to ensure their quality, performance and safety.
Sungold 400 watt solar panels HP-D-400W have obtained ICE63163 certification, RoHS, EMC CE, LVD CE professional certifications, which are in line with international certification standards, and the quality and performance of the product can be trusted.

Multiple LED lights or CFL bulbs.
Fans, such as ceiling fans or table fans.
Small household appliances like laptops, phone chargers, and small TVs.
Small household appliances like laptops, phone chargers, and small TVs. Camping equipment, such as lights and portable refrigerators.
Water pumps (small ones).
Charging batteries for later use.
Yes, 400w portable solar panels are suitable for both on-grid and off-grid systems.
Grid-tie system: In a grid-tie system, solar panels convert solar energy into electricity and inject it directly into the grid. This way you can use the power generated by the solar panels and at the same time get additional power from the grid (e.g. at night or when the weather is cloudy). In this case, you can connect your 400-watt portable solar panels to an inverter, which converts the DC power to AC power and injects it into the grid.
Off-grid system: In an off-grid system, portable solar panels convert solar energy into electricity and store it in a battery. You can use the electricity stored in the battery for power supply without relying on the grid. This type of system is ideal for use in areas without grid power or in situations such as camping in the wilderness. You can connect your portable solar panels to the battery via a charge controller to safely store the power.
Whether you choose a grid-tied system or an off-grid system, 400-watt portable solar panels can provide you with a clean, renewable power solution.
