Estimate your consume
There are different Solar Kits depending on the daily consume needed (W·h).
We have to take into account basically the consume of the element we have multiplied by the use time. If we have, for example, a light bulb that consumes 11W during 5 hours, we will have a total consume of 11W x 5 hours = 55W·h
Watts of the element (W) x time of daily use (hours) = daily consume (W·h)
We show as follows some examples of consumes in housing depending on the device or electrical appliance used:

Example in housing:
Lets imagine we want to calculate the consume in a house with the principal elements:
- 10 bulbs low consume 11W: 1 hours a day every light
- 1 TV of 32” of LED of 70W: 4 hours a day
- 1 Fridge Type A Combi with a daily consume of 950 W·h
This last information of the fridge consume can be found in the instructions.
The light bulbs consume using them 1 hour a day is a medium consume. What means that could have some of them working at the same time, but the summ of all the times can't exceed 10 hours:
1 unique bulb working 10 hours consumes the same than 10 bulbs working one hour.
The consume will be : 10 bulbs x 11 W x 1 hour + 1 TV x 70W x 4 hours + 1 Fridge 950 W·h/day = 1340W·h/day
This will be the medium consume in the housing and will need a kit according to the consume.
