FAQ

If your sias solar panels can work in hot area?

Yes – optimized for high temps (tested at 50°C+). Ask for our heat-resistance specs!

Will hail damage the panels?

Qualified panels are IEC 61215 certified and can withstand 25mm hail at 80km/h. The tempered glass is shatterproof and has a breakage rate of less than 0.1%.

Does it need regular cleaning?

Typically, 1-2 times per year (more frequently in dry, dusty areas). Dust can cause a 5-15% loss in efficiency. Self-cleaning coatings or tilted mounting can reduce maintenance.

What is the lifespan of solar panels?

The typical lifespan is 25-30 years, but can be much longer. The efficiency decay rate is approximately 0.5-0.8% per year, and after 25 years, it can still maintain 80%+ of its initial power.

Will they work on my roof?

Probably. We check your roof's direction, strength, and shading during a free inspection and provide you suitable mounting system.

What is your warranty?

We offer a 25-year performance warranty, a 10-12 year equipment warranty, and a workmanship warranty.

Can I add more panels later?

Yes, but it's easier and cheaper to plan for the right size from the start.

How is the module shipped and packaged?

Each module is packaged with reinforced protection using wooden pallets and corner guards. A 40HQ container typically ensuring safe transportation and optimized loading.
