Installing solar panels is one of the smartest decisions for those looking to reduce energy costs and increase the sustainability of their home or business.

But before moving forward, there are important concepts you should understand to ensure that your investment is secure, efficient, and tailored to your needs.

In this article, Enbiente explains 5 essential points about solar panels and self-consumption that will help you make the best decision.

1. Any consumer can benefit from a self-consumption system

Whether you are an individual or a business, you can generate your own electricity through photovoltaic solar panels.
In addition to reducing your electricity bill, it helps to decrease your environmental footprint and increases your energy independence.

Tip: The return on investment is more visible when consumption aligns with solar production hours (during the day).
For businesses, where activities are typically daytime, self-consumption is particularly advantageous – often without the need for storage batteries.

2. Analyze your electricity consumption

Each building has its own energy profile. Consumption can vary between:

• Weekdays and weekends;
• Day and night;
• Summer and winter.

Therefore, it is essential to evaluate your consumption patterns before determining the system's sizing.

Enbiente conducts a personalized self-consumption study, identifying the optimal point between production and consumption to maximize returns and minimize energy surpluses.

3. Savings are real and growing

With the installation of a solar system, you start generating energy at zero cost and lock in the electricity price for years to come – protecting yourself from constant market increases.

According to Eurostat, in the last 10 years, the cost of kWh has increased by:

• 50% for industrial consumers;
• 61% for residential consumers.

Self-consumption is, therefore, an ally of efficiency and profitability, reducing monthly expenses and increasing energy independence.

4. There is specific legislation for self-consumption

Decree-Law No. 153/2014 regulates distributed energy production and defines two main types:

• Self-consumption Production Unit (UPAC) – for self-use;
• Small Production Unit (UPP) – for total sale to the grid.

These regulations ensure that the installation meets the technical and legal requirements for safe operation.

5. Simple maintenance and long durability

Photovoltaic systems are robust and require minimal maintenance.

With basic care – such as periodic cleaning of the modules and checking the condition of the connections – it is possible to ensure optimal performance for 25 years or more.

Whenever technical maintenance is needed, you should rely on certified companies like Enbiente, ensuring safety and efficiency in the service.
