Discover how much solar panels would cost for your home by answering a few quick questions

What makes the best solar panel?

What qualifies as the “best solar panels” will vary from house to house, but quality and efficiency will be important universally (Adobe)

It’s important to balance the power output, efficiency and cost of any panel you’re considering, and if you have a house that isn’t in a shaded area and doesn’t experience regular harsh weather, you might benefit from a more basic solar panel with a lower output and efficiency level.

However, many top-rated designs consider roof orientation, potential for degradation, and light levels. Most older solar panels typically only worked well in sunlight, for instance, but the latest enhanced models can now use daylight,. This is ideal if your panels face a direction other than south, or if you have a tree nearby that could decrease your panels’ direct access to sun.

Similarly, if you’re looking to go more off-grid or maximise return on your solar panel investment – which you can do by exporting energy back to the National Grid using the Smart Export Guarantee (SEG) – looking for the highest output and best efficiency percentage will be vital to finding the best solar panels for you.

Make sure you speak to suppliers and national and regional installers from the start to clearly explain your requirements and to better understand how they can accommodate those needs. You can do this quickly and easily with our free quote-finding form – simply fill it out to be paired with the best solar panel rates from leading UK suppliers.

Finally, don’t be afraid to compare, or even to walk away, when the suggested solar panels installation doesn’t suit your home or budget; solar panels are a big investment and you should be informed and confident in your decision.

The following are the key attributes all the best solar panels have, including efficiency, power output, guarantees and degradation, plus their smart and sustainable credentials.

Solar panel efficiency

Solar panels are given efficiency ratings, which tend to range between 18 and 22 per cent. The higher the rating, the better, as this will correspond to how much electricity the solar panels will produce.  

Different factors, such as roof pitch, location, and size of the solar array, will also affect the efficiency of even the best solar panels. The aim is to ensure the panels are exposed to as much sunlight as possible, and choosing solar panels with added features to prevent elements that could impact their efficiency, and therefore power output, is important.

Solar panel power output

Output is how much energy you can expect your panels to generate. The Pmax, as marked up on data sheets, defines the maximum power output of a module in clear and bright conditions. As with efficiency ratings, the higher the number, the better. Most brands share both the Standard Test Conditions (STC) and Nominal Operating Cell Temperature (NOCT) in their data sheets. The latter measurement tends to be more realistic as it considers fluctuations in temperature, weather conditions and time of day. 

Below are the values you can expect in terms of energy generation per day, per module, based on the Pmax provided by these manufacturers using standard test conditions:

*based on 4.25h UK sunlight hours

Guarantees and solar panel degradation

Solar panels can last for up to 50 years, but typically there will be degradation over a 25- to 30-years period. This means that even the best solar panels’ efficiency will decrease over time. 

There are different types of degradation and suppliers and brands will mark up the estimated degradation on data sheets; it’s usually over a period of years from the onset or after a specific period, such as one year. Keep an eye out for enhanced PID resistance when picking solar panels for your home, as this should help maintain the panel’s generation rates over time. Without this, the panels are more prone to reducing in power output year after year. 

Solar panel guarantees are also an important detail to look out for. Examine how long the power output efficiency will be covered for so that, should the efficiency of your solar panels decrease far quicker than expected due to a manufacturing fault – or should they break – you’ll be able to get a replacement or another form of compensation.

Most domestic solar products come with a 12-year warranty; linear power warranties tend to start at 25 years, and some manufacturers offer a combined guarantee. However, read the terms and conditions carefully, as warranties will vary; and know how to report any complaints you have with your solar panels.

Smart and sustainable credentials

When investing in solar panels, it’s important to keep brand credibility in mind, as well as customer service, ease of installation, good ethics and the manufacturer’s stance on sustainability. Ensure that the panels are thoughtfully manufactured and look out for low/no lead or fluorine use in production. Similarly, check reviews, online ratings from websites such as TrustPilot, and certifications from industry bodies, like Trustmark.

Most solar panels can also be connected to smart meters and solar monitoring apps, so ask your supplier or solar panel installer for details about this; it’s a good way to keep track of how much energy your panels are producing, and how reliant you still are on the National Grid. It’s also especially useful if you’re eligible for the SEG, where you could make cash back for any energy you put back into the grid.

Do you need the best solar panels?

Finding the best solar panels is all about finding which product is right for your home and individual circumstance. Take into account your home position, orientation and energy usage. You should also consider any location concerns, for instance overhanging trees, shade from other buildings, or if you’re often exposed to harsh weather. Your decision to find the best solar panels should also include if you want to export excess energy back to the grid, or if you want to install solar battery storage alongside your array.

Frequently asked questions about best solar panels

The best solar panels for your home will depend on your budget, property size and orientation and your household’s energy usage . Start your search by comparing quotes and speaking to various installers about what they have in stock, costs, and what will work best for your home. 

The key elements to be aware of when researching the best solar panels are efficiency, power rating and enhanced design, like for example, if it’s built with Passivated Emitter and Rear Contact (PERC) cell technology and whether it runs off a string or microinverter system.

Researching the supplier you’re buying from is important, too – so be sure to thoroughly explore existing customer reviews and speak with neighbours who have installed solar panels for an honest, accurate perspective.

This year (2024) is a great year to invest in solar panels. As we approach net zero targets, you’ll be playing a significant role in offsetting CO2 emissions. Solar panels are costly to install, but have experienced a sharp cost decrease over the years, especially considering the solar panels grants available, and the investment is a great way to save on energy bills long-term and be generally less reliant on the grid.

The best angle for solar panels is between 30 and 40 degrees. During the solar panel installation process, your installer should consider the angle of your roof. The orientation and angle of your roof affect how much sunlight your solar panels will receive. Roofs at optimal angles maximise sunlight exposure and tend to convert more solar energy into usable electricity.
