Solar panels for businesses: reduce your company's energy costs
Cost reduction and stable supply
Companies with electricity consumption during business hours can directly use a large part of the energy produced by their solar panels.
This allows you to:
- Reduce electricity purchases from the grid.
- Lower exposure to rising energy prices.
- Improve operating cost forecasting.
- Make use of unused roofs and spaces.
- Reduce your activity's carbon footprint.
Profitability studied before investing
An industrial photovoltaic installation should be approached as a business investment. We prepare a technical and financial study that may include:
- Estimated solar production.
- Self-consumption percentage.
- Annual energy savings.
- Investment required.
- Estimated payback period.
- Return on investment.
- Accumulated savings during the system's lifespan.
- Comparison of different scenarios.
Turnkey solar panel installation
SolarTradex handles all phases of the project so the company doesn't have to coordinate different suppliers:
- Study and design: we analyse the energy profile and design the most suitable installation.
- Engineering: calculations, plans, technical projects and studies to execute with safety and guarantees.
- Installation and legalisation: we coordinate the work, install the equipment and manage permits, registrations and inspections.
Maintenance that protects the investment
A breakdown or an undetected drop in performance directly reduces the installation's savings. Our maintenance plans may include:
- Production monitoring.
- Alarm and incident detection.
- Panel, inverter and protection inspection.
- Thermographic inspections.
- Technical cleaning.
- Performance reports.
- Preventive and corrective maintenance.
How we install solar panels in your company
1. Technical and financial feasibility study
We analyse bills, consumption curve, roof surface and structure to prepare a personalised profitability study.
2. Engineering project and financing options
Plans, sizing, quote and options tailored to your company: direct purchase, leasing, renting or PPA.
3. Installation with in-house team and legalisation
We carry out the installation with no subcontracting, coordinate the work to minimise the impact on your activity and handle permits and inspections.
4. Industrial monitoring and maintenance
Monitoring system with alarm detection and preventive maintenance plans to protect the profitability of your investment.
Real cases of industrial self-consumption
Real cases of companies that are already reducing their electricity bill with solar energy in Catalonia and the Balearic Islands. We have developed projects for industries, logistics centres, cold storage warehouses, food companies, printing companies, cooperatives and public facilities. Discover in each project the installed power, the type of roof and the particularities of each industrial installation.
Drastically reduce the cost of your installation by combining the current grants available in Catalonia and the Balearic Islands. At SolarTradex we take care of the study, paperwork and complete management so you get the maximum tax benefit available.
- Personal income tax deduction up to 60% (RDL 7/2026): the new Royal Decree-Law extends deductions for homes: up to 20% for renewable self-consumption and up to 60% for energy renovation (combining photovoltaic + heat pump).
- Municipal IBI and ICIO reductions: most municipalities in Catalonia and the Balearic Islands apply reductions of up to 50% on IBI for 3-5 years and up to 95% on ICIO for projects integrating renewables.
- FACTOR 2026 programme · exclusive to the Balearic Islands: Balearic regional call with specific grants for photovoltaic, heat pumps, batteries and charging points.

Frequently asked questions about industrial self-consumption
How much can a company save with a photovoltaic installation?
Savings depend on electricity consumption, business hours, available roof space and the percentage of solar energy that can be used directly. At SolarTradex we analyse invoices and the hourly consumption curve to estimate annual savings and the real profitability of the photovoltaic project for companies.
How long does an industrial photovoltaic installation take to pay off?
The payback period varies depending on the investment, the current cost of electricity, the self-consumption level and the financing conditions. Each proposal includes an estimated return on investment based on the company's specific energy profile. Thanks to RDL 7/2026, companies can write off 100% of the investment in the first year.
Is it necessary to stop business activity during the installation?
Normally not. Work is planned to minimise any impact on productive activity. Specific actions that may temporarily affect the electricity supply (final grid connection, testing) are coordinated in advance with the company and are usually carried out outside working hours or during low-activity periods.
Does SolarTradex handle engineering and legalisation?
Yes. We offer a turnkey service: we handle the technical study, design, engineering, installation, permits, legalisation and system commissioning. The company doesn't have to coordinate different suppliers.
What maintenance does an industrial installation need?
It's advisable to monitor production in real time, periodically inspect the equipment and detect possible performance losses. An undetected breakdown directly reduces savings. SolarTradex offers maintenance plans with monitoring, preventive and corrective maintenance to protect the installation's profitability.
