  • Solar PV array installed on roof top of a house in Sri Lanka. This system consists of 6 solar PV modules each with 250 W capacity, an inverter and other accessories. This system is designed to produce 1500 W at its maximum operating conditions.



    โซล่าเซลล์ต่อปั๊มชักดูดน้ำขึ้นถัง (Solar cell and water pump)นำการใช้งานโซล่าเซลล์ต่อตรงมอเตอร์DCขับปั๊มชัก1นิ้ว ดูดน้ำขึ้นถังสูงประมาณ3เมตร หลังใช้งานมาประมาณ6เดือน ประมาณสัปดาห์ละ1ครั้ง การใช้งานยังเป็นที่น่าพอใจ แต่น้ำในบ่อต่างหากที่เริ่มแห้งลงไม่ค่อยพอดูด ถ้าต่อตรงโดยไม่ต่อแบตเตอรี่จริงๆถ้ามีบ่อน้ำเพียงพอสามารถใช้งานได้ตั้งแต่ 11.00น ถึง 15.00 น เลยครับ
