I'm new to working with solar and experienced a fantastic working experience with A1Solar. I ordered 6 pcs of Q Cells 400W solar panels from them and supply was quick / customer support was good! I look forward to purchasing from them once again Sooner or later. ขอบคุณที่มา : กรมพัฒนาพลังงานทดแทนและอนุรักษ์พลังงาน https://nimmansocial.com/story10684381/indicators-on-%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-you-should-know
