Find the answers to common questions regarding solar panel wiring and performance.
(1) The nominal rated power Pmax is the test data under Standard Test Conditions (STC), but the sunlight intensity, temperature, dust shielding degree, and installation angle in the actual environment might be different from the testing environment.
Under the same working conditions, the power generation of the two can be regarded as consistently similar.
It depends. It does not work well in overcast conditions. In cloudy but periodic sunlight conditions, although it might not be able to achieve the highest efficiency, the panel can still perform.
The rated power of the solar panel multiplies the system efficiency equals the solar panel’s real-time output of electricity. Under sufficient lighting, the actual power equals:. rated wattage x system efficiency x effective sunlight hours. The syste
(1) When the temperature rises, it will lower the output power of solar panels and the capacity to generate. (2) Stronger the sunlight intensity and the longer the sunline time, the more power the system will generate. (3) During the power generation
It is related to the selection of various parts of the system:. - Using MPPT controllers other than PWM will increase the system's efficiency. - Using a battery with a higher voltage rather than a lower one. - Using a connecting wire that loses less
Mono and poly panels will have color differences. For the same type of panel, there might be a slight color difference which is a normal phenomenon and will not affect the power generation.
We have standardized 12V and 24V solar panels, which can generate 20+V and 30V voltage. Working in 12V, 24V, or 48V depends on the rated voltage of the controller and battery in the system. The solar panel can meet the charging voltage requirements b
Some controllers can work in a 12V system, as well as a 24V one. They do not need manual adjustments since it has an auto-switch function.
It is not recommended to do so. Under appropriate conditions, panels with small wattage can directly charge the battery, However, the battery should not be left unattended. It should be disconnected manually when the battery is about to be fully char
The connection shall be in the following order except for the connection instruction specified by the system: connect the battery to the charge controller first, then the solar panel, and finally connect the load (optional). Disconnect the load first
The working temperature of the panel is -40°F to 194°F, which satisfies outdoor usage under extreme conditions.
The solar panel has been certified by international professional authorities for their resistance and working conditions under other harsh environments. Maximum hail and snow resistance is 5400Pa, and maximum wind resistance is 2400Pa.
Our panels will last you roughly 25 years depending on how they are used and maintained. For a manufacturer defect on the panels, we have a 2-year workmanship warranty. We also have a 90% power output warranty for 10 years and an 80% power output war
The solar panel is waterproof, the brackets can be used outdoors. Other non-waterproof will need a waterproof cover.
After the fully charged battery sits a while, the voltage will be kept in a range based on the battery’s condition, rather than a floating charge point. The normal range is from 12.5V to 13.2V. 12.6V after sitting a while is a normal rate, which is b
Other than charging for the first time, the controller detects the recharging voltage is too low when the system is not disconnected. The current is 12.5V which makes the controller determine that there is sufficient voltage. Thus, it will not start
(1) Other than the panel, other components should avoid direct sunlight. (2) All components need to be installed securely. (3) Be mindful of waterproof covers for outdoor installation. (4) Connectors should use the same specifications, make sure each
Damage to the surface could lead to irregular power generation, which can lead to electricity leakage.
There are many reasons for leakage. The system is designed based on photovoltaic system installation designs. The wiring is secure with a good grounding system, which shouldn't cause any electrical leakage.
