Photovoltaic System: How to Choose the Best Products for Efficiency and Savings

Introduction

Choosing the best products for a photovoltaic system is essential to maximize energy yield, reduce costs and ensure a long-lasting investment. In this article we will analyze the key components of a photovoltaic system, providing practical advice on how to select solar panels, inverters, storage batteries and monitoring systems, with a focus on quality, efficiency and reliability.

1. Photovoltaic Panels: Quality and Efficiency

Solar panels are the heart of the system and must be chosen carefully. Here are the main factors to consider:

• Type:

  • Monocrystalline: Higher efficiency (up to 22%), excellent for small spaces.
  • Polycrystalline: Cheaper but with slightly lower efficiency (16-18%).
  • Thin-film: Flexible, lightweight and suitable for unconventional surfaces, but less efficient.

• Efficiency and performance: A good panel must guarantee an efficiency greater than 20% and a low degradation rate (max 0.5% per year).

• Warranty and Durability: The best panels offer a 25-30 year warranty on energy production and at least 10-15 years on materials.

• Brand and certifications: Prefer reliable brands with international certifications (IEC 61215, IEC 61730, TUV, CE).

Recommended choice:
High efficiency monocrystalline panels with PERC or TOPCon technology, ideal for those seeking maximum performance and durability.

2. Photovoltaic Inverters: The Heart of the System

The inverter transforms the energy produced by the panels from direct current (DC) to alternating current (AC), making it usable for the home grid.

• Types:

  • String inverters: Suitable for medium and large systems.
  • Microinverters: Ideal for optimizing production in systems with shading or panels oriented in different directions.
  • Hybrid inverters: They allow integration with storage batteries for greater independence from the grid.

• Efficiency and reliability: A good inverter should have a minimum efficiency of 96-98% and a warranty of at least 10 years.

• Monitoring and connectivity: Choose models with remote monitoring functions via Wi-Fi or a dedicated app to control production in real time.

Recommended choice:
Hybrid inverters with high efficiency and advanced monitoring system, such as ZCS Azzurro inverters, perfect for those who want to integrate storage in the future.

3. Storage Systems: Energy Independence

Storage batteries allow you to store the energy produced to use it when needed, reducing dependence on the grid.

• Battery Types:

  • Lithium Iron Phosphate (LiFePO4): Long life (over 6000 cycles), higher safety and efficiency.
  • Lead-acid AGM or Gel: Economical but with lower duration and performance.

• Discharge capacity and depth:

  • Choose a capacity suitable for the home's consumption, avoiding undersized batteries.
  • Opt for a depth of discharge (DOD) greater than 80% for more efficient use of stored energy.

• Modularity and Scalability: Expandable batteries allow you to increase capacity based on future needs.

Recommended choice:
Modular, expandable LiFePO4 lithium batteries with a minimum 10-year warranty.

4. Mounting Structures and Power Optimizers

• Mounting structures: They must be resistant and made of anti-corrosion materials (anodized aluminum or stainless steel).
• Power Optimizers: Useful in partially shaded systems to maximize the production of each panel.

5. Monitoring and Maintenance Systems

• Remote Monitoring: Checking system efficiency in real time helps identify faults and maximize yield.
• Maintenance: Regular cleaning of the panels and checking the status of the inverter are essential for optimal operation.

Conclusion: What Are the Best Products for Your Photovoltaic System?

Choosing the right components is essential to get the most out of your photovoltaic system. Here is a summary of the best solutions:

• Photovoltaic panels: Monocrystalline PERC or TOPCon with efficiency greater than 20%.
• Inverters: Hybrids with Wi-Fi monitoring, high efficiency and battery compatibility.
• Storage batteries: modular, scalable and long-lasting LiFePO4.
• Mounting structures: Durable, anti-corrosion and suitable for the type of roof.
• Monitoring and Optimization: Inverters with advanced connectivity and power optimizers.
