The Sungold Story
Frequently
Asked Questions
Q1: Can Solar panels on metal roof produce all the electricity?
A: In most cases, it is normal for solar panels to be unable to provide their full nominal power.
Factors that affect solar panel performance:
Peak sunlight hours, sunlight angle, operating temperature, mounting angle, panel shading, neighboring buildings, etc…
Q2: How to test solar panels on metal roof?
A: Ideal conditions: test at noon, under clear skies, panels tilted 25 degrees to the sun, batteries in low state/less than 40% SOC. disconnect solar panels on metal roof from any other loads and use a multimeter to test the current and voltage of the panels.
Q3: How does temperature affect the efficiency of solar panels?
A: Solar panels are typically tested around 77°F/25°C and are rated for peak efficiencies between 59°F/15°C and 95°F/35°C. Increasing or decreasing temperatures can change the efficiency of a panel. For example, if the power temperature coefficient is -0.5%, the maximum power of the panel will be reduced by 0.5% for every 50°F/10°C rise.
Q4: How to mount our solar panels on metal roof using different brackets?
A: There are mounting holes in the panel frame to facilitate installation using various brackets. Z-mounts, tilt-adjustable mounts, and pole/wall mounts make the panel mounts suitable for a variety of off grid solar systems.
Q5: Can I connect different solar panels together?
A: While mixing different solar panels is not recommended, mismatching is possible with careful consideration of each panel’s electrical parameters (voltage, current, wattage).
Q6: What is A Solar Electric Fence?
Solar electric fence is an environmentally friendly alternative to traditional electric fencing. With a solar-powered electric fence, you can reduce your electric bill while protecting your livestock and crops from damage.
Solar panels convert sunlight into solar energy and are connected to a solar charger to further power the fence energy supply installation. In addition, many solar fences have a battery that is capable of storing electricity during the day and charging the fence at night or when there is no sunlight.
