As an Amazon Associate, Ecotero earns from qualifying purchases.

Choosing the best solar panels to buy is a challenging task and one that requires proper research.

This is because unlike other products, it isn’t possible to try a solar panel then request a replacement if you do not like its performance.

And while solar panels are sustainable source of energy and they will reduce your energy consumption at home, solar panels are not cheap.

Hence, it falls to your better judgement to make sure you are getting the value of what you’re paying for.

So to help you out, we round up 10 of the best solar panels you can buy from the market.

When looking for the the perfect solar panel for your needs, make sure to consider these factors:

  • Power – an essential factor to consider. You have to define your electricity consumption to match it with the product’s rated power capacity output.
  • Dimensions – size always matters. If you are investing a significant amount for these, it is important to know how many can you fit in your place.
  • Weight – If you put this on your roof, you need to ensure your roof can take the weight.
  • Efficiency – the next most essential factor refers to the amount of sunlight it can convert to electricity.
  • Cell type – It has three basic types: monocrystalline, polycrystalline, and thin film. (see more info in FAQ)
  • Temperature coefficient – refers to the decrease of efficiency when the panels’ temperature rises.
  • Warranty – as we’ve already said, solar panels are a one-time purchase. It is your assurance to buy solar panels in case of defects or malfunction.

Let’s check out your options.

Solar Panels Frequently Asked Questions

How many solar panels are needed to power a house?

Most consumers buy 20 to 25 solar panels for their homes, but still, it depends on your energy consumption. Having solar panels doesn’t mean you can exceed your normal energy consumption. The number of solar panels you buy should suffice your energy needs since it is not cheap.

Which solar panel produces the most electricity?

The entry-level of efficiency should start at 20%. The most efficient in the market has an efficiency rating of 22.8% but should be complemented with a low-temperature coefficient for much more stable use.

What are the most efficient solar panels?

Currently, the most efficient solar panels are produced by Sun power. They have managed to maintain high efficiency with a low-temperature coefficient. However, there are bifacial types of solar panels with an energy efficiency that can go as high as 25%.

What are the 3 cell types of solar panels?

The three types of solar cells are monocrystalline, polycrystalline, and thin film. Monocrystalline is the most efficient but pretty expensive. Polycrystalline is cheaper with less silicone waste but with only 13-16% efficiency. Thin-film cells are also cheap but a bit delicate making them unideal with a short lifespan and warranty.
