Disadvantages of Rooftop Solar Installations
1. Roof Condition and Space Limitations
A rooftop solar system depends heavily on the condition of your roof. If your roof is old or requires repairs, you’ll need to address these issues before installation, which can add to the overall cost. Additionally, if your roof lacks sufficient space for the number of panels you need, your energy production may be limited.
2. Accessibility for Maintenance
Maintaining rooftop solar panels can be more challenging compared to carport installations. Since the panels are located on the roof, cleaning and inspecting them for damage or debris requires additional effort. If you’re renting your holiday home, you might not always be around to keep an eye on the condition of your system.
Key Factors to Consider
1. Roof Space vs. Open Space
For international homeowners in the Algarve, the choice between a solar power carport and rooftop solar often comes down to available space. If you have a large, unobstructed roof, a rooftop system might be the better choice. However, if your roof is small or shaded, a solar carport offers more flexibility.
2. Energy Production
Both options provide excellent energy production, especially in a sunny region like the Algarve. However, if you’re limited by roof space, a solar carport can offer additional room for panels to increase your energy output.
3. Aesthetic Preferences
For those who value design and aesthetics, solar carports offer a modern, visually appealing solution. On the other hand, rooftop solar panels are generally more discreet, as they are installed on top of the house and are less visible from the ground.
4. Future-Proofing with Hybrid Inverters
Both solar carports and rooftop systems can be future-proofed with hybrid inverters, allowing you to add a battery later. This gives you the option to first focus on producing electricity and then, after seeing savings in your energy bills, invest in battery storage to maximize self-consumption.
Proof of Concept: A Happy Client in Lagos
At Voltaicos, we installed a solar power carport for an international homeowner in Lagos, Algarve. The client wanted to maximize energy production while providing shade for their vehicles. After conducting a detailed site assessment, we designed and installed a 12-panel solar carport that generates enough energy to power their holiday home and charge their electric vehicle. This setup not only reduces their energy costs but also adds a stylish, eco-friendly feature to their property.
Conclusion: Solar Power Carport or Rooftop Solar?
Choosing between a solar power carport and a rooftop solar installation depends on your specific needs and property. If you have a spacious, sun-drenched roof, rooftop solar might be the ideal solution. However, if you’re looking for added flexibility and a dual-purpose structure that provides shade for vehicles while generating clean energy, a solar power carport could be the better choice.
