Are you considering installing solar panels at your company and unsure where to start?
The transition to solar energy is now one of the smartest decisions: it reduces costs, strengthens energy independence and shows your company’s commitment to sustainability.
1. Can I install solar panels at my company to produce my own energy?
Yes. Since the publication of Decree-Law no. 153/2014, any company can install a self-consumption production unit.
This means you can produce part, or all, of the electricity you consume daily.
2. Do I need to change or create an electrical project?
No, as long as total installed capacity does not exceed 350 kW.
In these cases, installing photovoltaic panels does not require an electrical project.
Enbiente’s technical team carries out all checks and ensures the system complies with legislation and safety standards.
3. Does my solar system need to be registered?
Yes. All self-consumption installations must be registered with DGEG.
Enbiente handles the entire process, from registration to full legalisation.
4. What happens to the energy I produce and do not consume?
Production surplus can be injected into the public grid and later compensated.
At Enbiente, we assess each project so solar production matches real consumption as closely as possible, avoiding waste and maximising return.
5. How can I purchase solar panels for my company?
Enbiente handles the entire process: study, sizing, supply and installation.
We use high-quality equipment and provide technical support throughout every stage of the project.
6. What is the return on investment?
Return depends on several factors:
- Company energy consumption;
- Installed capacity and number of panels;
- Daily usage profile;
- Contracted tariff and available incentives.
In general, business systems have an average payback between 3 and 6 years.
7. What are my rights and duties as an energy producer?
As a producer, you must ensure the system’s technical and legal compliance, as well as installation safety.
Conclusion
Solar energy is no longer a trend. It is now a smart business strategy.
Enbiente has proven experience in business self-consumption solutions, combining precision engineering, premium equipment and close support.
