Misinformation is expensive. Let's clear up the myths surrounding photovoltaic systems in our country.

Myth 1: "Solar doesn't work when it rains or is cloudy."

Fact: Solar panels work on light, not heat. While output drops during heavy rain (to ~10-20%), they still generate power during cloudy moments. Malaysia receives 4-5 peak sun hours daily on average, which is sufficient for high returns.

Myth 2: "It makes my house too hot."

Fact: The opposite is true! Solar panels act as a second roof shade, absorbing the sun's heat before it hits your tiles. Many customers report their upstairs bedrooms are 2-3°C cooler after installation.

Myth 3: "I will have electricity during a blackout."

Fact: Standard grid-tied systems shut down during a blackout for safety (anti-islanding). Unless you have a hybrid inverter with a battery backup, you will also lose power.

Myth 4: "Maintenance is difficult."

Fact: Systems have no moving parts. Aside from occasional cleaning (handled by rain or yearly service), they run themselves.

Don't let myths hold you back from real savings. Calculate your exact savings in under 2 minutes, or see current solar panel prices to understand exactly what a system costs in 2026.
