The opportunity cost of roofs

Published: Friday, 12 July, 2019


If the business or industrial activity takes place in facilities over which we have rights of access and use of the cover, we may be missing an excellent opportunity to make the business profitable: install a photovoltaic self-consumption system on its roof that allows generating electricity with the that feed the consumption in lighting, air conditioning, machinery …

Photovoltaic technology has evolved in such a way that for several years now, it is the cheapest way to generate electricity and the most widespread in the world in new plant installations. Obviously, it is also the cleanest modality.

. A photovoltaic installation with double glass modules provides electricity at a fixed cost, less than a quarter of the price that is currently paying to the grid, with no fixed term or taxes.
. These modules are guaranteed for 30 years, their power also, and the whole installation enjoys a total guarantee insurance for 5 years.
. They are simple installations that are carried out in a very short time.
. Virtually no maintenance, no moving parts, no fluids, no gears, no vulnerable mechanism.
. Spain is a country with a privileged solar irradiation. The energy that is able to give a photovoltaic installation can represent a very high part of your consumption and your energy bill.

But not all panels are the same. The components and materials that make up a panel, as well as the industrial processes that require its manufacture, can be of many, little or no quality. The physical appearance of the module in the eyes of the layman produces the mistaken feeling that they are the same.

Before taking the step, it is essential to be informed, compare qualities and prices and analyze guarantees. As in any industrial product, quality goes hand in hand with higher prices and, normally, with those higher prices we buy tranquility and guarantee of response.
