Description:

The Center for Creative Ecology's EcoCampus Photovoltaic System www.kibbutzlotan.com/solar

The system was installed by Yarok4U www.yarok4u.co.il. It is a 16.485 kWp array of 58 ET Solar panels, each with a rated production of 280-295 Watts. A single SMA Sunny 15000TL three phase inverter connects the system to the grid at 240 volts.

The panels are mounted 2.2 to 3.3 meters above the ground which allows for them to dissipate heat more effectively than when mounted on a rooftop. The array has a slope of 5 degrees (most arrays in Israel are mounted at an incline of 30 degrees) in order shift production from a yearly maximum yield to a summer maximal production to correspond with the peak demand due to air conditioning for cooling.

The 100 square meters of solar panels doubles as a shade shed atop the community's recycling collection station and ecology education classroom. It provides electricity to the 10 Dome-atories and communal facilities of the EcoCampus Neighborhood (over 250 square meters of living space) and also offsets the carbon associated with the Green Apprenticeship Permaculture and Ecovillage Design programs and the Peace, Justice & Environment Academic Semester.

The EcoCampus dome-atories are exceptionally energy efficient, passive solar buildings. They are heated solely by sunlight in the winter and use less than half of the electricity needed to cool conventional buildings in this extreme desert climate. The walls are earth plastered straw bales on an earthquake resistant geodesic framework of steel pipe. The EcoCampus serves as an active example of combining efficient solar systems with energy conserving buildings constructed from sustainable materials to make carbon neutral neighborhoods.
