Solar Panels on the Market Today: A Buyer’s Guide

Now that you have read through our list of some of the most efficient solar panels UK stores have to offer, let’s explore some of the reasons we chose the solar panels we did and what makes particular models stand out amongst the crowd so you can make a decision and start saving on your energy bills as soon as possible.

What to Look For in the Best Solar Panels

While solar panel manufacturers follow standard test conditions and are rather forthcoming with product information, we think it’s helpful to know which specific traits are most important, aside from the PV cells themselves. The following traits helped us to narrow down the choices for our best-of list.

Efficiency

Solar panel efficiency is extra important for people with limited roof space on top of their homes or for anyone with limited or less than ideal sun exposure. The module efficiency is greatly affected by exposure conditions. The higher the efficiency rating, the better solar panel efficiency will be.

All of the options on our list feature decent to high solar panel efficiency.

Temperature Coefficient

The temperature coefficient assigned to solar panels also describes how well they work in shady areas or extreme temperatures, both hot and cold. If you exceed the temperature coefficient range, they will not perform as expected. Therefore, the temperature coefficient of a solar panel is more important when it comes to functionality in particularly hot or cold climates. Make sure to look for the temperature coefficient associated with panels if you expect to be using them in the climate conditions described above.

Accessories

Many, but not all solar panels come with added accessories and bonus port capability. Common accessories included with solar panels include connection cables which vary greatly in length, a charge controller to regulate energy and protect against power surges, and mounting brackets.

Some solar panels, a few of which are concluded on our list, also come with adapters like alligator clips so you can easily attach the panels to a car battery or USB ports so you can charge smaller devices like your phone or tablet.

Ease Of Use

Ideally, your solar panels should also be easy to use and easy to install. Considering the rapid growth in solar panel use, many people are beginners when it comes to using them. That’s why we aimed to pick beginner-friendly panels backed by a company with good customer service.

Installation ease is extra important if you plan on travelling with your solar panel system and will need to assemble and disassemble it frequently.

If installing solar panels just isn’t your thing, you can always opt to pay for a variety of professional installation services. For some, this may be well worth it but we specifically chose solar panels for our list that are easier to install so most people should not need help from professional installers.

Benefits of Solar Panels

Solar panels are an excellent way for you to lessen your energy bills. By harnessing the power of the sun with the best solar panels on the market today you can counterbalance some expenses associated with electricity bills for your home. Or, you can bring energy to remote areas while camping, boating, or any other type of off-grid adventure.

A smaller, portable style solar panel is also great for charging your phone, laptop or other devices on the go. They can even be used to jump-start a car if the battery drains.

Types of Solar Panels

There are three main types of solar panels: polycrystalline, monocrystalline, and thin film. All of the options on our best solar panels list feature monocrystalline cell technology but it helps to be aware of the complete range of solar PV systems on the market so you can make an informed decision for your energy needs.

Monocrystalline (Mono) Solar Cells

Monocrystalline panels are the ones most people are familiar with and have seen in and around their communities. Mono cells feature a uniform appearance. Mono cells are also easy to link into a PV system.

  • Most efficient
  • Less sustainable

Polycrystalline (Poly) Solar Cells

Poly cells are also common for homes. Poly cells have a broken appearance. Poly cells are recognizable by their blueish colour.

  • Less efficient
  • More sustainable

Thin Film Solar Cells

Just as the name suggests, thin film solar cells are thin and many are somewhat flexible. Considering their lower efficiency range, we chose to exclude these types of panels from our list.

  • Most sustainable
  • Least efficient

Which Solar Panel Works Best In Shade?

Considering all we have learned from our solar panel reviews, monocrystalline cell technology possesses the greatest efficiency range and will therefore perform the best in shade. However, even the best solar panel need some direct sunlight to work.

To maximise power output and efficiency potential, try to install your solar panels facing south, where they will get the most exposure to sunlight. Additionally, your solar panels should be installed or set up at an angle so that more of the surface is exposed for a longer amount of time.

Choosing the Right Solar Panel for Your Home

Not all panel manufacturers on the market today provide you with a range of results so it can be tricky narrowing down the best solar panels. Choosing the best solar panel for your home or mobile roof should be easier than ever thanks to our reviews and helpful buyer’s guide.

Our favourite choice is the ECO-WORTHY 150W solar panel. These solar panels provide you with a durable aluminium frame that makes installing solar panels easy and beginner-friendly. They also have great efficiency and energy output. However, they don’t come in the best packaging or with mounting equipment.

If the ECO-WORTHY 150W solar panels aren’t the best choice for your roof or home, one of the other options on our list may be better suited to your specific needs. Whichever company you decide to go with let us know what you think in the comments below.
