Solar PV Module Buyer's Guide

By SB Staff

For the PV Module Buyer's Guide, we sent a questionnaire to every major solar panel manufacturer. This Guide is a snapshot of their global and U.S. capacity, what's new this year, and their top product lines. Click products to expand for more information.

If you want to learn more, please visit our website.

The solar module market is more competitive than ever in terms of pricing and power rating. So, what else should residential and commercial solar installers and procurement teams consider when selecting solar modules?

 'With the Inflation Reduction Act (IRA) expected to accelerate residential and C&I solar deployment, thanks to more certainty around the long-term extension of the Investment Tax Credit (ITC), demand for high-power and high-efficiency modules with long-term warranties will grow more competitive. Installers must ensure they have access to a dedicated module supply to avoid project delays, procurement problems, and customer dissatisfaction,' ' Melissa Cavanagh, Marketing Manager, North America, Trina Solar.  

'The variety of solar modules available in the U.S. market, from both established and new players, is growing. Installers know that not all modules are created equal, and selecting a relatively unknown module company comes with risks in terms of warranty, reliability, performance and customer service. Established, bankable brands ' whose modules go through rigorous third-party testing by labs like PVEL and RETC ' offer peace of mind and a proven track record,' Elena Zhang, General Manager of DG North America for LONGi Solar.

'As the solar industry grows in importance, so does our responsibility to become more sustainable too. Consumers are far more cautious about the environmental footprint of the products they are buying and want to make more responsible choices. Installers must be aware of sustainable aspects of their modules' portfolio, on top of technical features.' ' Cary Hayes, President, REC Americas.

Other key trends to note when scrolling this year's PV Module Buyer's Guide:

• The switch from p-type cells (PERC) to n-type (TOPCon and HJT) is on. Learn more about the difference in performance and failure points here.
• Larger format modules are coming to residential and commercial rooftops. RETC explains the reason for the large-format revolution and what it means for DG installers. Learn more about why that matters for off-grid solar projects right here.
• Domestic manufacturing capacity is on the rise. We asked for that stat in this year's questionnaire. You can get a more detailed outlook for U.S. PV supply here. However, given the complex preliminary guidance for the domestic content adder, the source of the PV cells at that plant will be key to understand in future years. Get more insight on 'domestic content' challenge here.

How to Choose Macaroni Production Line?

1. Choose an MCS-Accredited Installer

The base line standard accreditation for solar is MCS (Microgeneration Certification Scheme). This is the only recognised industry watchdog for solar installers in the UK. Accredited installers undergo annual audits covering installation standards, warranties, and after-sales care. They also maintain a database of approved panels and ensure your system meets all legal and safety requirements.

To check if an installer is MCS accredited, visit MCS Certified. If an installer isn't MCS-approved, walk away. You wouldn't hire a non-accredited gas engineer to fit your boiler'why risk it with your solar system?

At Solarfix, we go beyond industry standards, proudly achieving ISO , , and certifications. These globally recognized accreditations reflect our commitment to excellence in health and safety, environmental management, and quality assurance. We continuously strive to be the best, ensuring our customers receive top-tier service, reliable installations, and the highest quality products.

2. Check for an Insurance-Backed Warranty

A reputable installer should offer an insurance-backed warranty scheme, which protects your investment in two ways:

• If the installer ceases trading before your installation, the policy refunds your deposit.
• If an issue arises during the warranty period and the installer is no longer in business, an accredited installer will carry out repairs free of charge.

At Solarfix, we use IWA'one of the most recognised and rigorous providers of insurance-backed warranties. They thoroughly vet our financial status, supplier payments, and customer documents. Learn more at IWA.

3. Ask for Local References

A trustworthy installer should have a portfolio of completed projects in your area. Ask for references and speak to previous customers to get honest feedback on their experience. We've installed over 2,000 systems, and you can find our customer reviews here.

Many of our customers come from referrals, which is a testament to the quality of our work and customer satisfaction. We believe that word-of-mouth recommendations are one of the strongest indicators of a company's reliability and expertise. Our customers trust us enough to recommend us to friends and family, and that speaks volumes about the service we provide.

4. Don't Get Hung Up on Panel Brands

Many salespeople will push a particular panel brand, but in reality, there's little difference in real-world performance between Tier 1 manufacturers. Chinese manufacturers dominate the market, producing some of the highest-quality panels globally. JA Solar is a great choice, offering an excellent balance of price, performance, and UK support.

5. Plan for Battery Storage

Home storage batteries offer a smart and efficient solution for households that are unoccupied during daylight hours'precisely when solar panels are generating the most solar power. Without a battery, surplus solar energy is often exported to the grid, only for homeowners to buy back electricity at higher rates in the evening when energy demand peaks.

By integrating home storage batteries, you can store excess solar power generated during the day and use it in the evening or overnight, reducing reliance on the grid and maximising the benefits of your solar investment. This not only lowers electricity bills but also ensures you're making the most of your renewable energy.

While solar power in Northern Ireland is less abundant in winter due to shorter daylight hours, you can still optimise your energy use. Charging your battery overnight on a cheaper night tariff allows you to take advantage of off-peak electricity rates, ensuring greater savings even during months of reduced solar generation.

It's important to invest in quality when choosing a home battery system'buy cheap, buy twice is especially true in the solar industry. A home battery is a significant investment, and you want a reliable system that will stand the test of time. At Solarfix, we only supply top-tier battery solutions, including the Duracell home battery and the SolarEdge Energy Bank.

We have strong partnerships with both manufacturers, and as a Platinum Installer for Duracell Energy and a Preferred Installer for SolarEdge, we can offer priority support and hassle-free resolutions should any issues arise. This ensures you get not only a high-quality product but also the best aftercare and long-term reliability.

 6. Install an EV Charger with Your Solar Panels

If you own or plan to own an electric vehicle, installing an EV charger alongside your solar system can save on labour costs. The My Energi Zappi car charger is an excellent choice, allowing you to charge your EV directly from solar power.

The My Energi Zappi car charger offers three flexible charging modes, allowing you to power your EV using grid electricity, solar energy, or a combination of both. Whether you want to maximise solar self-consumption, adapt to changing weather conditions, or ensure a full charge for longer journeys, Zappi gives you the freedom to choose.

And when the darker months set in, you can charge your vehicle overnight using a cheaper off-peak tariff, further reducing your energy costs. Designed and manufactured in the UK by MyEnergi, the My Energi Zappi car charger is built to last, offering exceptional reliability and performance for years to come  (If you have multiple MyEnergi devices (such as the MyEnergi Eddi immersion heater controller, you can control them all from one app.).

7. Don't Rush ' Make an Informed Decision

Going solar is a long-term investment, and the process should be enjoyable, not stressful. You should never feel pressured into making a decision on the spot. A reputable solar company will give you time to think through your options and ensure you're comfortable before proceeding.
