WT 250P is a robust photovoltaic panel, composed of 60 solar cells. The photovoltaic module can be included in on/off grid applications. In the WT 250P panel production process only Kiwa and ISO 9001:2015 certified raw materials are used to provide high long term performances. The rigorously performed quality control on the entire technological flow ensures the high quality of the Wattrom photovoltaic panels.
All the WT series photovoltaic panels are distinguished by high efficiency of up to 16.50% and output power tolerance of 1.6%.
The excellent sunlight transmission capacity is the main advantage of the WT 250P module. This contributes to obtaining a higher rate of sunlight absorption with beneficial effects on the overall efficiency.
