This project is based on the design and calculation about a solar photovoltaic installation for
three residential buildings. Each residential building is made up of 10 houses located at the
north of Tenerife, concretly in Los Realejos. This document explains and analyzes the diferent
aspects that must be taken into account to develop a photovoltaic installation in residential
buildings.
We have to comment that the installation is carried out with the aim to produce savings in
electrical energy for the residents. For this, we have carried out an investigation on the available
space in each building, to determine the number of modules that we can place, and therefore,
the maximum power that we will install. Subsequently, we have estimated the energy
consumption of the 30 households to see if we can satisfy that demand with the calculated space.
Finally, we evaluated various installation options and opted for the most effective in both the
energy and economic fields.
After evaluating what we have commented, we conclude that we can install a total of 206
modules. Knowing that we have used LG modules whose nominal power amounts to 340 W,
the total installed power will be 70,04 kW.
Therefore, we can affirm that we will have a photovoltaic installation with connection to the
electrical grid with compensation, since we have a power of less than 100 kW. In this modality,
there is an economic incentive for the sale of surplus energy, so it adapts perfectly to our
conditions by having several hours throughout the day in which this phenomenon occurs.
Finally, it is important to comment that this project includes planes for the installation of the
modules, protections and cables, which provide very useful information for the people who will
carry out the installation. In addition, a budget has been calculated where all economic aspects
are taken into account.
