Best Solar Panels for Cloudy Days

Solar energy provides the only solution to our rapid energy usage and keeping the environment safe. With renewable energy, you’ll always have enough power for your day-to-day work. As it’s based on sun rays, cloudy days might give you a reason to concern over, but if you get solar panels that were designed to perform efficiently in cloudy weather, then you have nothing to worry about. And that’s why we’ve put a lot of the best solar panels for cloudy days just for you.

Buying Guide

Before diving into our top picks of the best solar panels for cloudy days, we need to discuss what makes a solar panel prioritized as one of the best options for a cloudy day.

Efficiency Type

Depending on their efficiency, solar panels that are good for cloudy days can be divided into three types. These three are:

  • Monocrystalline Solar Panels
  • Polycrystalline Solar Panels 
  • Thin-Film Amorphous Silicon Solar Panel

Monocrystalline Solar Panels

Monocrystalline Solar Panels are the best options among the three types if we consider efficiency as it provides almost 20% efficiency rate. It is also the costlier of the other two types. 

These solar panels come with a black tint which gives them a great exterior design and exclusive look that just says premium at the get-go. The cells have one silicon at the center, which helps a monocrystalline solar panel to have that extra efficiency over its competitors.

Polycrystalline Solar Panels

Polycrystalline Solar Panels are second best when it comes to efficiency and performance. It guarantees an efficiency rate of 15% and a straight forward overall performance. They come with a blue tint coating over the panels.

The downside of this type of solar panels is longevity and high-temperature issues. This increases the chance of malfunction, which must be avoided if you rely solely on solar panels as your power supply. These solar panels are also heavier than most.

If you are on a tight budget but want good features, then this is the type of solar panels you should go for.

Thin-Film Amorphous Silicon Solar Panel

If you want the cheapest solar panel type out there, you should go for a Thin-Film Amorphous Silicon solar panel. Their efficiency rate is the lowest among the three types. It has an efficiency rate of 10%. This type of solar panels is very light and can be used in mobility situations.

Being the cheapest solar panel out there, Thin-Film Amorphous Silicon solar panels has several issues. They have very bad durability and tends to have a short lifespan than most other solar panels.

You should only go for this type of solar panels if you are on a real tight budget and want to have the most affordable option in the market. But be prepared to handle the flaws that it comes with it.

Solar Panel’s Suitability with Your Roof  

If you buy a solar panel that doesn’t fit with your roof’s proportion, then you just wasted a lot of credit for solar panels that you won’t be able to properly use. 

The first and the most important thing you need to look out is for the size of your solar panels and their suitability. The number of panels that you’ll need is also dependent on this decision. 

Output per Panel

It is also essential to know how much output you’ll get from the estimated panels you’ll have to buy. Talk with the manufacturer's customer support or the seller’s engineers to get an accurate number. Because depending on your need, you should buy solar panels. You don’t need to waste money on the energy that you don’t need.   

Warranty Period

Last but not the least is the warranty period. A warranty period ensures that the manufacturer believes that the product will last for at least this time. There is 3 to 4 type of warranties in play when you will buy a solar panel, so make sure you got all of them right.
