While it varies from home to home, US households typically need between 10 and 20 solar panels to fully offset how much electricity they use throughout the year. The goal of most solar projects is to offset your electric bill 100%, so your solar system is sized to fit your average electricity use. [pdf]

Estonia's electricity sector is interconnected with regional energy markets, particularly through connections with and . The direct electrical interconnection with Finland was established in 2006 and was further strengthened by the interconnector in 2014. Estonia joined the market by 2012, securing its own price area within this regional electricity market. [pdf]
