Solar powerplants integrated efficiently with commercial real estate

Systems were contracted from Lahti Energia, a local power company by the managing company of the properties, Hämeenmaan Kiinteistöt. The motivation for adopting solar power was the desire to take part in the common good and appeal to customers as well as financial as the company estimated they would gain significant savings.
The panels directly feed into the power system of the store which uses nearly all of the energy consumed with only small amounts sold into the grid, allowing for higher efficiency as grid losses are negated.
For grocery stores, solar power is advantageous as the peak production and peak load are at the same time. Power production peaks are midday in summer when the weather is hottest which is simultaneously the peak load for grocery stores as hot weather drives up cooling demand. Also, unlike residential buildings which consume more energy in the evening as people come home from work, grocery stores mostly consume energy during the day thus getting maximum use out of solar energy.
Additionally, the same corporate group that runs the properties owns a share of wind farms, which supply 65 % of the electricity purchased from the grid giving an even higher fraction of renewables used.
