„Gebalis goes solar“

It‘s not if we can‘t pay it, is like we don‘t want to!

2

Main purpose Help people from low-income urban zones to save

money

Simulate a PV-System production to see if it can match the energy consumed by a typical family

Analyze daily routine

Changing consumer behaviors

Decreasing energy

consumption

3

Stakeholders Gebalis:

- Public Housing Authority – born in 1995 – around 2500 houses in Lisbon

- owns 23 PV-Systems connected to the grid-> the returns are invested for the buildings

Families:- low income people living in residences managed by

Gebalis- see the PV-Systems of Gebalis as a private business-

>look askance at it

Project planStep

1• Meeting with Gebalis + see the PV-System

Step 2

• Meeting with a family, living in a Gebalis flat: interview and installation

Step 3

• Installation in our flat for tests

Step 4

• Meeting with a family: interview and installation

Step 5

• Monitoring and analysis the energy consumptions

Step 6

• Simulate the working of a standard PV-System and compare the amount of energy produced with the amount of energy consumed by a family

Step 7

• Communicate results and advices to the people involved using graphical communication tools

6

explain our project to Gebalis

ask for support to identify the families and work with them

Meeting with the family (Gebalis) Gebalis put us in contact with a family that lives

in one of their flat in Lisbon.

We installed the device (“Cloogy – Home”) to measure the energy consumption and to collect data about the family that lives there, through a brief interview.

The family is made up of only one woman, since her daughter is at the moment studying abroad.

“Cloogy – Home”

- Clamp and Transmitter: is connected to the electricity meter of the flat and send the information to the Hub - Power Plug: measures the consumption of one domestic plug and send the information to the Hub - Hub: is connected to the internet modem and send the information from the Transmitter and Power Plug to the Web Portal (http://ienergy3.isa.pt:8o8o) - Display: shows the real time information and the accumulated consumption

Monitoring and analysisThe values measured by the Cloogy-Home device are continuously monitored and studied in order to define the profile of the family concerning the “energy behaviors”.

The graphs that show these values are very useful to identify when the main energy consumption occurs and what amount of it could be avoided.

Simulation of the PV-System using the software PVSYST V5.0 - select: panels, inverter, angle, location, period of the year,

etc.

Gebalis PV-Systems:- 24 Multicrystalline-Panels per System (best cost-performance ratio)- 160Wp per Panel - Inverter: SunnyBoy3800- 1 System produce about 550kWh (~400€) during a summer month

Compare the simulated PV-System to the existing Systems from Gebalis
