Sistemas fotovoltaicos de autoconsumo para los sectores residencial, terciario e industrial

Multisistemas Energías Eficientes is a Canary Islands company specialising in the study and execution of self-consumption PV systems for the residential, tertiary and industrial sectors. With a cumulative experience of over 10 MW, the company is committed to quality in both the choice of leading component manufacturers, as well as their assembly and commissioning.

One of the most emblematic installations from Multisistemas Energías Eficientes is the 70 kWp facility at the Roque de los Muchachos Astrophysics Observatory. This exemplary industrial sector installation is a reference thanks to its location, constructed at an altitude of over 2,500 metres in a natural park on the island of La Palma (Canary Islands). 272 modules were installed from manufacturer QCells, each with an output of 285 W, along with four Fronius inverters (2 x 20 kW and 2 x 15 kW). This is a very interesting installation, not only because of the energy saving it provides, given the high number of solar hours per year of the site, but also because it is a showcase facility for every visitor to the observatory.

Another industrial sector installation undertaken by Multisistemas Energías Eficientes has been for the AGUSA banana cooperative. The cooperative wanted to reduce environmental pollution to achieve clean production. Multisistemas Energías Eficientes implemented a 33 kWp self-consumption installation using 320 W mono-PERC modules from JA Solar. A total of 104 units were installed, along with two 15 kW Fronius Symo inverters and a structure angled at 18º made of anodised aluminium from Extrugasa. Thanks to this installation, the cooperative has achieved a 34% saving in the cost of electricity. The facility generates an estimated 59,799 kWh per year.
