KIEV, Oct. 16 – The capacity of power accumulation systems integrated into photovoltaic modules will grow exponentially in the coming five years and at the end of 2017 will reach five gigawatt-hours, Activ Solar Chief Operating Officer Johann Harter said, referring to the forecast of IHS international company.

"Despite the fact that Ukraine remains a new solar power market, it's important to start discussing the possibilities of accumulating power now. Inexpensive and large-scale solutions will be the Holy Grail for renewable energy, as they will allow solar and wind power plants to ensure the continuous flow of energy to the power grid," he said at the Renewable Energy & Energy Efficiency Forum in Kiev on Tuesday.

Harter said that today there are several efficient solutions allowing the accumulation of power generated by solar power plants during the day that can be realized in Ukraine –pumped-hydroelectric storage, storage of compressed air, and the power-to-gas solution.
