Photovoltaic installation in Mallorca: process, registration and setup

Intro

A photovoltaic installation in Mallorca is more than just mounting panels. For a solar energy system to work reliably and actually reduce your electricity bill, the roof, consumption, electrical system, registration, feed-in tariff, and electricity plan must all match up.

For many English-speaking and international owners, Spanish bureaucracy is the main source of uncertainty. What documents are needed? Does the local municipality need to be involved? When does the feed-in tariff become active? Sunglow Energy guides you through these steps locally and explains them clearly in English.

Step 1: Solar Check and Electricity Bill

Everything starts with a property assessment. This includes roof area, orientation, shading, the condition of the electrical installation, and your electricity consumption. The electricity bill is particularly important because it shows how large the system should ideally be and whether the tariff or the Potencia (contracted power) can be optimized.

Particularly in places like Sóller, Deià, Valldemossa, or other locations with unique topography, shading, roof pitch, and visibility can play a larger role. That is why planning should never be one-size-fits-all.

Step 2: Technical Planning

Based on the gathered data, the suitable PV system is planned. This includes:

• Module output and inverter

• Battery storage options

• Wallbox or EV charging

• Cable routing and electrical connection

• Maintenance access

• Monitoring via app or portal

For properties with a pool, air conditioning, or holiday rentals, we also check when electricity is actually needed. This makes it easier to decide whether a battery storage system is practical.

Step 3: Registration and Documentation

The installation is only one part of the project. In Spain, technical documentation, registration, and, depending on the case, coordination with the relevant authorities are essential. Which documents are required depends on the property, system capacity, municipality, and type of system.

Sunglow Energy clarifies the approval path before making an offer and assists with all necessary steps regarding documentation, registration, and feed-in activation.

Step 4: Installation and Commissioning

Following the final planning, the installation of the PV system takes place. Sunglow communicates a typical assembly time of 5-7 days for the installation, depending on the scope of the project, roof, electrical work, and availability. Please note: This is not automatically the entire project duration including registration or subsidy approval.

After commissioning, the monitoring system should be set up and explained. This allows you to track yield, consumption, and feed-in.

Step 5: Tariff and Bill Check

After the system is activated, the first electricity bill is highly important. It shows whether the feed-in, compensation, Potencia, and tariff are correctly reflected. That is exactly why Sunglow Energy combines photovoltaics with electricity tariff optimization.

Conclusion

A photovoltaic installation in Mallorca works best when it is cleanly planned from a technical standpoint and fully supported administratively. For owners, this means: less uncertainty, better comparability, and a system that is not just installed, but actually works properly.
