Frequently Asked Questions
Q
What is the difference between PERC and TOPCon technology in 500–550W solar panels?
PERC (Passivated Emitter and Rear Cell) technology adds a reflective layer to the rear of the cell to capture more sunlight, improving efficiency over standard cells. TOPCon (Tunnel Oxide Passivated Contact) is a newer generation that further reduces electron recombination losses, achieving higher efficiencies — often exceeding 21%. Both options are available across the brands we supply, and our team can help you select the right technology for your project requirements and budget.
Q
Are 500–550W solar panels suitable for residential rooftop installations?
Yes, while 500–550W panels are commonly used in commercial and utility-scale projects, they are increasingly being adopted for larger residential rooftops. Their higher wattage means fewer panels are needed to achieve the same system output, reducing installation time and hardware costs. Our technical team can advise whether this panel range suits your specific roof size, load capacity, and energy targets.
Q
How do I ensure the 500–550W panels are compatible with my existing inverter?
Compatibility depends on your inverter's maximum input voltage, MPPT voltage range, and maximum input current. All panels we supply come with full electrical datasheets. Our technical team can cross-reference your inverter's specifications — whether it's Sungrow, Growatt, GoodWe, Huawei, SolarEdge, Enphase, or others — to confirm compatibility and recommend the optimal stringing configuration.
Q
What warranties are included with the 500–550W panels you supply?
All panels we supply carry the manufacturer's original warranties, which typically include a 10–12 year product (workmanship) warranty and a 25-year linear power performance warranty guaranteeing at least 84.8% of rated output. First-year degradation is guaranteed at ≤2%, with annual degradation thereafter at ≤0.55%. As authorized distributors, we coordinate directly with manufacturers for any warranty claims.
Q
Can I order a mixed container with panels from different brands?
Yes. We offer flexible procurement options, including mixed container shipments combining panels from multiple brands. This is particularly useful for distributors or installers who serve diverse customer needs. Contact our sales team with your volume requirements and preferred brands, and we will provide a tailored quote with competitive pricing.
Q
Do you provide support for customers in East Africa, including Uganda?
Absolutely. We are actively expanding our presence in East Africa with an upcoming Uganda branch designed to provide localized warehousing, faster delivery, and on-the-ground technical assistance. Whether you are a developer, installer, or distributor in Uganda or the wider East African region, our team is ready to support your solar projects with genuine products, competitive pricing, and responsive after-sales service.
