this project is ongoing since year 2010.

napenergiához kapcsolódó tevékenységek. a rendszer 200wp panelből, szigorú 12v-os dc hálózatból és 540ah @ 12v mélykisüthető akkuból áll. ez táplálja a lakás lapanet.hu/led oldalon részletezett világí­tását, valamint a lapanet.hu/kompjuta/v7 oldalon tárgyalt számí­tástechnikai rendszert.

progress with solar energy. the implementation consists of 200wp pv panels and a strict 12v dc system backed up by 540ah@12v deep-discharge batteries. the system serves the lighting of the house as found on page lapanet.hu/led, and also the home computing infrastructure found on lapanet.hu/kompjuta/v7.
