When comparing solar quotations, 90% of homeowners look at the "Total Price" first. That’s normal—everyone wants to save money.

But a solar system isn't a standardized product like an iPhone. It's more like a "Custom PC"—assembled by the installer using various components (panels, inverters, cables, mounting). If cheap components are used, the RM5,000 you saved today might be lost in Year 5 due to system failure.

Today, Solar100 teaches you how to see through the price fog and identify the true "Hardware Quality" in a quotation.

1. What is a Tier-1 Solar Panel? Why Does It Matter?

You often hear salespeople say, "We use Tier-1 panels." But this isn't just a marketing buzzword; it’s a financial stability standard defined by Bloomberg NEF.

• • Definition: Only manufacturers with their own factories who have supplied financing for multiple large-scale projects make the list.
• • Meaning: This indicates the brand is financially solid and unlikely to go bankrupt in 25 years. If you don't choose Tier-1, and the manufacturer shuts down, your "25-Year Warranty" becomes a worthless piece of paper.

2. The Inverter: The "Brain & Heart"

Solar panels generate electricity, but the Inverter converts it into usable AC power for your home and monitors safety. It is the most complex and fragile component.

"Cheap inverters not only have low conversion efficiency (meaning less electricity generated) but are also prone to overheating and failure. Always stick to top global brands like Huawei, Sungrow, Growatt, or Solis."

Solar100 Standard: We only accept installers who offer Global Top 10 Inverter brands, ensuring your system's "brain" is smart and robust.

3. Invisible Details: Mounting & Cabling

The devil is in the details. Many "cheap" quotations cut costs here:

• • Inferior Mounting: Non-aluminum or thin galvanization leads to rust after a few years, causing roof leaks.
• • Generic Cables: Not using specialized DC Solar Cables (UV resistant) causes the insulation to crack under the sun, creating fire hazards.
