Summer is the season with the highest solar incidence of the year — a known fact. But what isn't always considered is that this characteristic directly influences the performance, financial return and technical use of a photovoltaic system.

At Geoclima, we monitor various residential and business projects and notice that those who install during summer tend to obtain faster and more efficient results. 

In this article, we explain why.

Maximum production right from startup

A solar system's performance depends directly on solar radiation and the number of daily exposure hours. In summer months, the average production increases significantly, which guarantees maximum use from the first day of operation.

In Portugal, a 5 kWp system can produce more than 900 kWh just between June and August — equivalent to almost 40% of a house's average consumption in the same period.

By installing at this time, the system immediately enters operation at its highest performance point, with direct impact on the energy bill.

Faster investment return

During summer, energy consumption is also higher, especially with the use of air conditioning systems and equipment connected for longer periods. This means that produced energy is used more intensively — and the return on investment accelerates.

On average, systems installed in summer reach break-even up to 6 months earlier than systems installed in winter — just due to consumption and production differences.

Additionally, it's possible to monitor system behavior early, adjusting use according to the residence or business consumption patterns.

Facilitated installation and greater technical predictability

More stable weather conditions in summer favor planning, reducing delays and interference. Additionally, there's greater availability of installation windows and technical scheduling.

At Geoclima, we guarantee a complete process:

1. Technical study and viability analysis
2. Personalized project
3. Installation with certified professionals
4. After-sales monitoring and assistance

Integration with intelligent air conditioning

Another relevant factor at this time is the possibility of integrating efficient air conditioning solutions with solar systems, like heat pumps, electric vehicle chargers and thermal management systems.

With this integrated approach, it's possible to maximize the residence's energy autonomy and optimize the return of all installed solutions.

Conclusion

If you're considering installing solar panels, summer offers ideal conditions:
☀️ more sun, more production
💶 more consumption, more return
🛠️ more technical predictability
