ABSTRACT
Photovoltaic (PV) systems are becoming more and more popular around the world, and
Latvia is not an exception. This is mainly due to the increased efficiency and reduction
in price of PV modules. However, Latvia still ranks below most European Union countries
in the use of PV modules for electricity production. A significant problem for many farms
and households in Latvia which use PV modules, is the lack of storage for the produced
electricity. As a result, large amounts of electricity are sold for a relatively low price and
while being bought from the main grid for a relatively high price. The aim of the study is to
determine and compare the electricity consumption and PV systems producing electricity
each month on the Jasmini Farm during 2020. The study shows that during the year, only
25.4% of all the electricity used on the Jasmini Farm was from PV modules, but the rest of
the electricity was bought from the main grid. Furthermore, from all the electricity which
PV modules produced in 2020, only 29.5% was used on the farm, while the rest was sold
to the main grid.
