I'm new to applying solar and experienced an excellent working experience with A1Solar. I requested 6 pcs of Q Cells 400W solar panels from them and shipping was rapid / customer care was good! I stay up for purchasing from them once again in the future. ขอบคุณที่มา : กรมพัฒนาพลังงานทดแทนและอนุรักษ์พลังงาน - https://listfav.com/story22388061/top-%E0%B8%82-%E0%B8%AD%E0%B8%84%E0%B8%A7%E0%B8%A3%E0%B8%A3-%E0%B8%81-%E0%B8%AD%E0%B8%99%E0%B8%95-%E0%B8%94%E0%B8%95-%E0%B8%87-solar-rooftop-secrets
