Villa roof
20KW Grid-Connected System on Truncated Villa Roof
20 KW PV grid-connected Power System features in long life expectancy(25 years), noiseless, no electromagnetic wave radiation, clean and no pollution, etc. Built-up area is 150 kms or so; daily electricity generation is 50-80 degrees, deversified in different areas; cost returns in 5-7 years; and with national electricity subsidies: 0.42 Yuan/Degree.
The project adopts Poly C-Si high-efficiency PV modules 50KW,outputs and connects to grid by inverting to 380V. According to practical construction condition, fixed concrete pillar, water-proof treatment on villa roof, immobilized by using color steel tile as tiling fixture, this project taks use of 50KW high-efficiency stable grid-tied inverter, 380V outputing, through specific grid-connected switchgear and access.The scope of service on this program is limited to inverter triphase output end.
Module: 20KW POLY C-Si(or MONO) modules
Inverter: One piece of 20KW Triphase Inverter
Support Bracket: One set (customized design according to practical size)
Cable: One set of PV direct current and alternating current cable
