Photovoltaic solar panels for self-consumption can produce part of the electricity needed for your home, reducing dependence on the grid and helping control energy costs.

Before moving forward with an installation, it is important to understand how this type of system works and which factors should be assessed in order to choose a solution suited to your needs.

How photovoltaic solar panels work

Solar panels capture energy from the sun and convert it into electricity. This energy can be consumed directly in the property during the day, at the moment it is produced.

For this reason, the main goal of a photovoltaic self-consumption system is to match solar production as closely as possible to the household's consumption profile. The better this balance, the greater the use of the energy produced.

Assessing the property's energy consumption

Before choosing solar panels, the property's electricity consumption should be analysed, especially during daytime hours. Equipment such as heat pumps, air conditioning systems, washing machines, water heaters or electric vehicle chargers can strongly influence system sizing.

An oversized system may produce energy that is not fully used. On the other hand, a system that is too small may not deliver the expected savings.

Installation conditions

The orientation, inclination and solar exposure of the roof are essential factors. It is also important to check whether there are shadows caused by trees, buildings, chimneys or other structures.

Even small shaded areas can reduce system performance, which makes an on-site technical assessment essential.

Panel power and system sizing

The choice of system power should not be based only on the number of panels. It is necessary to consider the property's real consumption, available space, inverter type, peak usage hours and the possibility of adding batteries in the future.

A properly sized system helps improve return on investment and increase the property's energy efficiency.

The importance of a technical assessment

Every home has different needs. Before installing solar panels, a technical visit should be carried out to collect information about consumption, installation conditions and the customer's goals.

With this information, it is possible to propose a safe, viable solution adjusted to the real needs of the property.
