Key Factors to Consider When Purchasing Solar Panels

If you’re planning a DIY solar installation, it’s important to remember that the cheapest option isn’t always the best. Beyond price, consider these key factors for buying solar panels:

Panel Efficiency

Efficiency refers to how effectively a solar photovoltaic panel converts sunlight into usable electricity. Most modern panels have efficiencies of at least 20%. Higher efficiency means more power from limited roof space, which is especially valuable for smaller or shaded roofs.

The type of solar PV panel you choose impacts efficiency:

  • Monocrystalline solar panels are the most efficient and durable, often making them the best choice for maximising output in limited space.
  • Polycrystalline panels tend to be less efficient but are usually more affordable, suitable for larger roofs where space is less of a concern.
  • Thin-film panels have lower efficiency and shorter lifespans but can be flexible and lightweight, ideal for unconventional installations.

Warranties and Product Lifespan

A robust warranty is important to protect your investment. Look for panels that offer at least a 25-year performance warranty and a 10–12-year product warranty. This ensures long-term reliability and manufacturer support if issues arise. 

Keep in mind, panels from providers with longer or more comprehensive warranties often come with a higher upfront cost, reflecting their quality and durability.

Manufacturer Quality and Reputation

Panels from reputable, Tier 1 manufacturers—such as JA Solar, Canadian Solar, LONGi Solar, and Jinko Solar—are built to higher quality standards and are backed by established supply chains and customer support. Choosing a trusted brand can offer peace of mind and stronger long-term performance.

System Compatibility

Solar panels are just one component of a complete system. You’ll also need a compatible inverter, mounting system, and potentially a battery. Purchasing through a reputable provider helps ensure that all elements are properly matched and integrated, reducing the risk of performance issues down the line.

Are DIY Solar Installations Worth It?

For those looking to save money, a DIY solar installation can be tempting. However, while the savings can be substantial, there are several important considerations before taking the DIY route.

Limited Access to Incentives

To qualify for most UK government incentives—including the Smart Export Guarantee (SEG)—your system must be installed by an MCS-certified professional. DIY installations typically don’t meet this requirement, meaning you could miss out on ongoing payments or other financial support.

Safety and Compliance Requirements

DIY installers must still comply with Part P of the Building Regulations, which governs electrical safety in homes. If your system connects to the grid, you’re also legally required to notify your Distribution Network Operator (DNO).

Even if you install most of the solar panel system yourself, certain aspects—like electrical work and grid connection—must be completed or signed off by a qualified electrician. Failing to meet legal and safety standards can result in fines, disconnection from the grid, or the need to remove and redo the work.

Warranty and Insurance Limitations

Most manufacturers offer limited warranties on DIY kits, and many will void the warranty entirely if the system is not installed by an accredited professional. Likewise, home insurance providers may not cover damage or liability arising from self-installed systems, especially if the work isn’t certified.

Risk of Poor Performance or Damage

Incorrect installation can lead to a loss in efficiency, underperformance, or safety hazards such as electrical faults or fire risk. Without the proper experience or support, troubleshooting these issues can become costly and time-consuming.

Although purchasing panels independently and installing them yourself might appear more cost-effective initially, the expenses associated with installation, system design, and compliance often surpass those savings. For this reason, most homeowners opt for full-service providers to ensure a reliable and hassle-free solar installation.

Alternative Options to Purchasing Solar Panels Individually

If buying solar panels outright isn’t the best fit for your budget, there are several alternative options to help make solar more affordable and accessible. From flexible financing to government-backed incentives, these solutions can help you get started with solar PV panels without the full upfront cost.

Solar Panel Financing

If the upfront cost of solar is holding you back, solar panel financing can help. Many UK homeowners are now choosing to spread the cost over time using options such as:

  • Interest-free loans offered by some banks and local councils
  • Installer-backed payment plans
  • Buy-now-pay-later or low-APR financing options

With the right plan, your monthly payments could be offset by the energy savings you make. Just be sure to review all terms carefully—including interest rates, repayment periods, and any early exit fees. For a full breakdown of your options, check out our guide to solar panel financing.

Government Schemes and Local Incentives

Several government-backed schemes and local initiatives are designed to reduce the cost of solar PV panels, especially for low-income or energy-inefficient households. These include:

  • The Energy Company Obligation (ECO4) scheme, which offers funding for eligible homes to install solar panels and other energy efficiency measures.
  • The Warm Homes Plan provides grants to support households in need with renewable energy upgrades such as solar installations.
  • The Solar Together scheme, a group-buying program organised through local councils that helps residents secure competitive prices and flexible financing options.
  • The 0% VAT rate on solar panel installations, available until , which can only be claimed if your system is installed by an MCS-accredited installer.

Taking advantage of these incentives can significantly lower your upfront costs and improve the rate of return on your solar panel investment.

Let's Recap

Finding solar panels for sale has never been easier, but making the right choice requires careful consideration. The cheapest panels aren’t always the best—look for quality, efficiency, and reputable brands backed by solid warranties. 

While DIY installations might seem cost-effective upfront, they typically do not qualify for important government incentives like the Smart Export Guarantee (SEG) or 0% VAT unless installed by an MCS-certified professional.

Full-service installations, on the other hand, provide expert design, professional fitting, and certification—ensuring your system is safe, efficient, and eligible for all available financial benefits. Choosing a professional installer not only protects your investment but also maximises your long-term savings and peace of mind.
