Installations of photovoltaic solar energy for industrial self-supply
Industrial companies have two assets that make photovoltaic energy an especially profitable investment: a work rhythm that coincides with solar time, and large roof areas. Thus, a lot of electricity can be generated and consumed at the same time, which maximizes its value. The electricity production achieved is what it will no longer be necessary to buy on the grid: between 35% and 50% of current consumption. The cost savings go further, being able to reduce the contracted power, and sell / offset the surpluses in the network.
We also work for the public sector (city councils, county councils, etc.): both executing the final work after a tender, as well as performing prior technical advisory services.
How does the solar panel installation for companies work?
The sunlight impacts the panels and creates a current. We recover this current to electrify your company.
It gathers the solar production from all the modules and transforms it into alternating electricity of 230V – 400V, which will be poured into the internal network of the building.
Because the surplus is poured into the network, you will not need to store energy in them. Batteries are mainly used in homes and isolated installations.
It is not only telematic (distance reading), but it also calculates the electricity poured into the network so the distributor company can pay you for it.
How long will it take to recover the investment?
Investing in solar energy is one of the best decisions you can make. It allows you to control a key factor in the production: the energetic costs.
The repayment is quite quick: in just 5 years the investment will be recovered. Or, from another perspective, the internal rate of return is between 15 and 20%.
The economies of scale are the key factor: you can use the outdoor areas of your company and generate the energy you need, without having to pay tolls or taxes for it. We install an equipment with 25-year warranties (although it can last 40 years), so the economic efficiency is guaranteed, and the fixed maintenance costs are very low.

Grants or subsidies to install solar panels
Solar energy is worthwhile for itself, but some cities and towns encourage companies to take the plunge.
There are three types of grants: property tax, trade income tax, and construction permit tax grants. Depending on these grants, you can recover your investment in less than 5 years.
From SUD we will help you to manage these permits and will provide the documents you need to complete to receive the city council’s grant.

Frequently Asked Questions
Yes, we have technical solutions for all sorts of roofs. Inclined roof with simple overlays, with sandwich overlay, flat waterproof roof…
Yes, although you will need the authorization of the owner to do so. You can try to reach an agreement with the owner to share the installation costs.
All options are possible, but we advise you to create your own energy in situ. We can do it in different ways: through a rise in the rent price or through a service agreement by which the owner sells the solar kWh to the tenant, at a private and agreed price.
Not at all: its mission is to be up there for 25 years, so you do not have to worry. That’s why it is installed by professionals. You won’t need to do anything: the rain will clean away the dust piled up in the gaps. If it hails, do not worry, the glass is designed to stand and hold (a car window breaks easier than many solar panels).
