Reading the specifications

Detailed specifications for SunGold Power 500W Mono Black PERC Solar Panel | UL 61730 + CEC Listed | 21.05% Efficiency | 1500V | SG500WM | 25-Year Warranty have not been published yet. Sungold lists this solar panel in the Solar Panels, and we add fields as the manufacturer releases them — in the meantime, ask your distributor for the datasheet before ordering.

For a solar panel, the figures that matter most are physical dimensions and weight, which decide what fits your roof and mounting, open-circuit voltage (Voc) and short-circuit current (Isc) for string design, rated power in watt-peak (Wp) measured at standard test conditions and module efficiency, typically 19–23% on current products. Panels are the generating half of the system and the part that determines how much energy is available at all. They are also the longest-lived component, routinely still producing over 80% of their original output after 25 years.

What to check before ordering

The checks below apply to any solar panel. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Prefer a lower (closer to zero) temperature coefficient in hot climates. Panels lose output as they heat up, and on a 45 °C roof the difference between −0.34 %/°C and −0.29 %/°C is real energy over a year.
Read both warranties. The product warranty (typically 12–15 years, up to 25 on premium modules) covers manufacturing defects; the separate performance warranty guarantees output — commonly 87–92% remaining at year 25.
Check the physical dimensions against your usable roof area before ordering. Modern modules are large, and a layout that works on paper can fail against obstructions, walkways and setback rules.
Consider N-type TOPCon or bifacial modules where space is tight or the mounting is elevated and reflective — bifacial gains of 5–15% are realistic over a light-coloured flat roof or the ground, and close to zero flush against a dark tile roof.

Where buyers lose money

Buying the highest wattage available without checking the inverter's MPPT voltage window — a string that sits outside the window produces less, or nothing.
Assuming rated power is what you will see. Real-world output at midday is typically 75–85% of the nameplate figure after temperature, soiling, wiring and inverter losses.
Underestimating shade. A single shaded cell can suppress an entire string unless you use module-level optimisers or microinverters.

Price and availability in United States

SunGold Power 500W Mono Black PERC Solar Panel | UL 61730 + CEC Listed | 21.05% Efficiency | 1500V | SG500WM | 25-Year Warranty is listed at $ 1,390 (USD) for United States. Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in United States: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Sungold locally before ordering.

SunGold Power 500W Mono Black PERC Solar Panel | UL 61730 + CEC Listed | 21.05% Efficiency | 1500V | SG500WM | 25-Year Warranty is listed at $ 1,390 (USD) for United States. The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

SunGold Power 500W Mono Black PERC Solar Panel | UL 61730 + CEC Listed | 21.05% Efficiency | 1500V | SG500WM | 25-Year Warranty is a Sungold product, listed under solar panels with model reference SG-500WMx4. The Sungold brand page lists the rest of its range so you can compare across the catalogue.

That depends on what it has to connect to. For a solar panel, check cell technology — mono PERC, N-type TOPCon, HJT, or bifacial, temperature coefficient of power, usually −0.26 to −0.35 %/°C and first-year and annual degradation, and the performance warranty that guarantees them against the rest of your equipment before price enters the decision. Consider N-type TOPCon or bifacial modules where space is tight or the mounting is elevated and reflective — bifacial gains of 5–15% are realistic over a light-coloured flat roof or the ground, and close to zero flush against a dark tile roof.

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in United States — buying in-channel is what keeps the manufacturer's warranty valid.
