How do Project Solar Evolution Elite solar panels work?

The Project Solar Evolution Elite solar panels are made up of two types of materials: monocrystalline and polycrystalline. Polycrystalline solar cells are made from multiple crystals of silicon, whereas monocrystalline solar cells are made from just one.

The company claims that its panels are more efficient because they use a type of solar cell that allows the panels to absorb more sunlight. In fact, the Project Solar Evolution Elite solar panels are able to convert up to 21% of the sunlight that hits them into electricity. This is a significant increase over the efficiency of traditional solar panels, which typically only convert around 15% of the sunlight they receive into electricity.

The higher efficiency of these solar panels means that they can produce more electricity, even in areas with lower levels of sunlight. This makes them ideal for use in the UK, where light levels are often not high enough to power traditional solar panels.

Project Solar also claims that the Evolution Elite solar panels can withstand higher temperatures than traditional solar panels. With the increasing frequency of heatwaves in the UK, the product’s tolerance for hot weather conditions might be a plus point to consider.

How does the Project Solar Evolution Elite compare to other solar panels?

We compared Project Solar with three of the top solar panel competitors in the UK. The table below indicates that Project Solar provides the best (and only lifetime) warranty. It offers an output second only to the LG Neon R, which is best on the market. While they’re one of the more expensive solar brands, the cost includes a combination of good output and efficiency – as well as that extensive warranty. So in our view Project Solar’s Evolution Elite solar panels are a worthwhile investment.

How much do Project Solar Evolution Elite solar panels cost?

Project Solar does not give prices for individual panels on its website. Instead, the company provides prices on a quote-by-quote basis, which depends on the number of panels needed and any specific installation requirements. However, as stated in our table above, a typical system consisting of 14 panels costs around £8,000. Other online estimates place the price per panel at about £350. This makes the Project Solar Evolution Elite one of the more expensive options on the market, but its lifetime warranty makes it worth the price.

How to maintain Project Solar Evolution Elite solar panels

As a homeowner, you’ll want to make sure that your solar panels are always in optimal condition. After all, they help you save money on your energy bills and they’re also good for the environment. Here’s our advice on how you can maintain your Project Solar Evolution Elite solar panels:

Check the panels regularly

Make it a habit to check your solar panels at least once a month. Inspect for any cracks, scratches or corrosion. If you do notice any damage, it’s best to call a professional to have the panel repaired or replaced. Attempting to carry out your own repairs may void your warranty.

Keep the panels clean

Dirt, debris or leaves accumulating on the panels can impact their efficiency. It’s important to have them cleaned at least once a year so they can receive maximum sunlight exposure. You may need to do this more often if you live near a busy road or an area prone to dust.

You can simply use a low-pressure garden hose to clean the panels, which should not involve getting on the roof. However, to ensure the job is done in a safe manner, and to avoid any possible damage, we recommend hiring professionals to clean your solar panels.  

By following these simple tips, you can help ensure that your Project Solar Evolution Elite solar panels stay in good condition for many years to come.

What the professionals say

“Project Solar’s monocrystalline solar modules employ a high-efficiency cell technology called passivated emitter and rear contact, or PERC. It promises to improve cell voltage and current and generate up to 10% more power per square metre compared to standard solar panel modules. Interestingly, it also promises better low-light performance to help you generate more energy in darker months of the year.

“If you’re living in your forever home, these could be the best panels for you. However, if you think you might move within the next 10 years, then a less expensive option with a shorter warranty could be preferable.”

“A lifetime warranty is a very attractive feature when investing in something as costly and permanent as solar panels for your home. And with a promise of 80% performance after 30 years, Project Solar UK’s solar panels seem a safe investment you can count on. If you’re living in your forever home and don’t plan to move, the Evolution Ultramax 345MB-66 could be the best solar panel in the UK for you.

There’s a lot to like about Project Solar Evolution Elite 400 solar panels. They offer good efficiency and high power outputs that will last for decades. Sure, there are a few panels in this price class that can beat their output and performance over time, but none offer a lifetime guarantee. Their lucrative cash referral bonuses means you could put cash back into your pocket through energy savings and recommendations.”

What customers say

Project Solar has a good rating of 4.7/5 on Review Centre and 4.1/5 on Trustpilot. Here’s what Project Solar’s customers are saying about their products:

“My experience of PSUK was/is excellent and I would thoroughly recommend it to family and friends. The team arrived on time to install. Installation went very smoothly and was well explained afterwards. Was making my own energy as soon as the system was switched on. One very happy customer – thank you.”

“Impressed with the information provided. The customer service is good and they check in with you to make sure it all goes smoothly every step. Really quick and easy installation. Very happy with our new panels.”

“From the beginning Project Solar offered a no pressure sale. Whilst they were not the cheapest I was happy with the support of Andrew the salesperson and the information provided by PSUK. The installation was done on the agreed date by the installation team. They were quick, professional and informative. I have now recommended PSUK to my sister.”

Our recommendation

If you’re looking for a top-of-the-line solar panel, the Project Solar Evolution Elite is a great option, and you’ll be impressed with its high efficiency. 

Project Solar Evolution Elite solar panels are built to withstand even the harshest weather conditions, and they come with a lifetime warranty, so you can rest assured they’ll keep working properly for a long time.

The only downside to the Evolution Elite is that it is one of the more expensive solar panels on the market.
