1. Photovoltaic system - Altamira

2. Global analysis
1. Seven portals with their own electricity meter and two for each garage:
- all the lights on the external side are connected in a mixed way with the portals
- portal THREE is the entrance for the electricity of the garden = BIG consumer.
- the costs are: 1. “potencia": fixed and important amount depending on the
maximum you may need
2. real consumption
3. “impuestos” (taxes)
2. Lights:
- about 90% of the lamps are replaced during the last three years by LED-lights.
Needs to be examined which are the other 10% (for example: large garden lights?).
Remark : potencia: has it been adapted to a lower consumption?
- light sensor: on the garden lights.
3. Switch: separates the lights from the basement and the hall

3. What may be done? Measures to reduce consumption.
Lights in the garage of building 1: split in (at least three) zones and initiated by motion detectors. Now all the lights are always ignited. (Antonio)
All the light bulbs should be replaced by (Philips/Osram) LED-bulbs: 10% still conventional. Within less than a year or two positive cost/benefit. The life time of LED-lights is now also considerably longer.
Most important consumer = motor for the water supply (building1 - garage).
Full power everytime when somebody opens a water tap = a very frequent, very intense and short peak current. Reduce the consumption by 50 % = 10 years (at the actual electricity price!) to get a break even.
The life time of the motor will be extended considerably.

5. What may be done? Measures to reduce consumption.
Consumption of portal 1-7 varies between 199 to 300 kWh/month: reasonable explanation for this difference of 50%?
Elevators of portal 6 and 7: install a motion detector/switch (now: 24h/24h enlightened)
Reduce the number of electricity meters?
The potencia of every portal 1-7 and the garages should be revaluated after the changes.

6. Solar panels Location 2. roof (blue): (visual) problem for some people
1. about 70 m² in front of the building (white)
next to the dental clinic
- cleaning / eliminate IUCA ‘s
- NOT ENOUGH for general
consumption
  2. roof (blue): (visual) problem for some
people
- roof tile colour (price!)
- general consumption
- ev. private consumption (division
of costs?)

7. Solar panels: Location roof is the unique option
  Connection mostly not a problem
Price 5 companies – not interested (at the moment)
Problem - large price difference between in (consumption)/out (storage
on the grid) = NOT profitable AT THE MOMENT
- battery = disconnection from the grid
Proposal allocate 50 E/unit/sem. from the actual community fee
to a “solar panel reserve”

No legal problem
