Effect of Temperature on Photovoltaic Solar Energy Conversion: 3 Tips for Algarve Homeowners

17 de December, 2024 Voltaicos No Comments

Introduction to Photovoltaic Solar Energy Conversion

Photovoltaic solar energy conversion is the process by which sunlight is transformed into electricity through solar panels. This clean energy technology is a cornerstone for sustainable living, especially in sunny regions like the Algarve, Portugal. However, did you know that temperature can significantly influence the efficiency of your solar panels? In this blog, we’ll explore how temperature impacts photovoltaic solar energy conversion and share insights for maximizing your system’s performance.

Whether you’re a permanent resident in the Algarve or own a holiday home, understanding this phenomenon is vital to ensure your solar panels operate optimally year-round.

How Temperature Affects Photovoltaic Solar Energy Conversion

Solar panels are designed to harness sunlight, but temperature plays a significant role in their efficiency. While many assume that hotter conditions lead to better energy production, the opposite is often true.

The Basics of Temperature Coefficient
- Solar panels are most efficient at specific temperatures, typically around 25°C (77°F). When the panel’s surface temperature rises above this threshold, its efficiency decreases.
- The rate of efficiency loss per degree Celsius is called the temperature coefficient, which is usually between -0.3% and -0.5% for most panels.
High Temperatures and Energy Output
- In hot climates like the Algarve, solar panels can heat up to 60°C or more, leading to a reduction in
  photovoltaic Solar Energy Conversion efficiency by up to 20%.
- This reduction occurs because high temperatures increase the internal resistance of photovoltaic cells, hindering the flow of electricity.
Cold Weather Benefits
- On cooler, sunny days, panels operate more efficiently, producing more electricity for the same amount of sunlight.
- This is why solar installations in the Algarve can still perform excellently during the mild winter months when many international homeowners return to their properties.

Designing Solar Systems for Optimal Performance

To mitigate the impact of high temperatures, it’s crucial to design solar systems tailored to the Algarve’s unique climate. Here’s how:

Choosing High-Quality Panels
- Invest in panels with a low temperature coefficient, such as those from top brands like JaSolar, Trina, and Jinko, which we install at Voltaicos. These panels are engineered to maintain efficiency even in high temperatures.
Proper Panel Installation
- Ensuring adequate airflow beneath the panels can help dissipate heat. Our team carefully positions panels to maximize cooling and efficiency.
Regular Maintenance
- Dust and debris can exacerbate heat absorption. Regular cleaning ensures your panels remain cool and efficient, especially during the Algarve’s hot summers.

Real-Life Example: A Client’s Solar Installation in Albufeira

One of our clients, Anton, owns a holiday home in Albufeira. He wanted a system that could handle the Algarve’s intense summer heat while maintaining performance during winter. Our solution? A 12-panel system using JA Solar panels with a low temperature coefficient and a high-efficiency inverter. Since installation, Anton has enjoyed consistent energy savings and hassle-free operation, even during peak summer temperatures. Learn more about our solar solutions here.

Benefits of Solar Energy in the Algarve’s Climate

Year-Round Sunshine
- The Algarve boasts over 300 days of sunshine annually, providing ample energy production opportunities, even in winter.
Reduced Energy Bills
- Despite efficiency losses in summer, solar panels in this region still generate significant electricity, reducing dependence on the grid.
Environmentally Friendly
- Switching to solar energy significantly lowers your carbon footprint, contributing to global sustainability efforts.

Enhancing Solar Efficiency with Battery Storage

Pairing your solar panels with a high-quality battery system can further optimize energy use. A solar battery allows you to store excess energy generated during cooler hours and use it during hotter periods or at night. Check out our options for solar battery storage and discover how they can complement your system.

Can You Sell Electricity Back to the Grid in Portugal? Earn Up to €0.08 per kWh in the Algarve

10 de December, 2024 Voltaicos No Comments

Can You Sell Electricity Back to the Grid in Portugal?

If you’re an international homeowner in the Algarve, either living there permanently or managing a holiday property, you may be wondering if you can sell surplus solar energy back to Portugal’s electricity grid. The answer is yes—you can sell any excess energy and contribute to the grid while lowering your energy costs. Here’s a guide on setting up a self-consumption system that lets you produce, consume, and even sell solar power back to the grid.

Step-by-Step Guide to Sell Electricity Back to the Grid in Portugal

Setting up a solar system in Portugal that enables you to sell electricity back to the grid involves a few important steps to ensure compliance with regulatory standards:

Step 1: Determine Your Profile

Identify your energy profile and what you aim to achieve with the solar system. Decide if you want to produce electricity just for personal use or if you also want to inject surplus energy into the grid.

Step 2: Consult with an Authorized Technician

Work with a licensed technician to design and install your system. They’ll help you select the right equipment and navigate the registration process. For convenience, check the list of accredited technicians on the DGEG website, or consult our team at Voltaicos.

Step 3: Register on the DGEG Self-Consumption Portal

If your installation exceeds 700W or you wish to sell electricity back to the grid, register on the DGEG Self-Consumption Portal. You’ll need:

Your Point of Delivery Code from your electricity bill
Your NIF Number (tax identification)
Installation details, including the authorized technician’s information

Step 4: E-REDES Analyzes Your Request

After you register, E-REDES will assess the setup. If the requirements are met, they’ll approve the application and provide a link to track the installation’s progress.
