How to Compare Solar Panels

Product Warranty

It is important to research both the quality and the product warranty of your solar panels before you make your investment. The best way to do this is to check out their in-depth review on our solar panel product review page. Pay particular attention to the length and type of warranty as well as the efficiency and output of the panels. So please make sure you check the type of warranty before buying.

Performance Warranty

The warranty is one of the most important elements of your solar panels, as this is the part that will safeguard your investment in case something goes wrong. A performance warranty is a guarantee that your panels will continue to perform to a certain standard over the lifetime of the warranty. This is expressed in an expected loss of power output capacity (ie: 10-20% over the first 25 years). These warranties aren’t always as straightforward to redeem, but they provide a good indicator of the expected degradation of the panels.

Cell Efficiency

Cell efficiency is determined by the cell structure and base silicon material used which is generally either P-type or N-type. Cell efficiency is calculated by what is known as the fill factor (FF), which is the maximum conversion efficiency of a PV cell at the optimum operating voltage and current. The cell design plays a significant role in panel efficiency. Key features include silicon type, multiple busbars (MBB), and passivation type (PERC).

Panel DImensions

When looking to place solar panels on your roof, one of the key factors you’ll have to consider is their size and output. Solar panels come in the standard 1.70m x 1.0m dimensions with an output ranging between 250 – 340 watts. While output varies, in most cases the size of the single solar panel will not change.

Temperature Coefficient

The temperature coefficient measures the amount of power reduction per degree rise of temperature above 25 degrees that your panels experience. As your panels overheat, their efficiency and power output drops. The temp coefficient indicates how the panels will perform in hot conditions.

Brand Reputation

Most of the solar panel manufacturers use is the “Tier 1” rating. The Tier rating was developed by Bloomberg New Energy Finance Corporation and is basically used to rate solar panel manufacturers in terms of financial stability. With most established panel manufacturers now rated as Tier 1, it is more important than ever to know how to distinguish a high quality and reliable panel by other means which we explain in more detail in our solar panel quality review. Based on our international rankings, below is our list of the best residential solar panel manufacturers rated according to quality, reliability, performance, warranty and service, along with feedback from solar industry professionals.

Monofacial vs Bifacial

Monocrystalline (mono) solar panels are a premium solar panel technology with higher efficiency rates than their poly panel alternatives. As a result, mono panels tend to have a higher starting price. Unlike the poly technology, mono panels use a single crystal of silicon that is cut into wafers. This gives the electrons more room to move and results in a more efficient solar panel. Mono panels have a more sleek design, more efficient solar generating capacity and therefore a higher price point. Mono panels can be identified by the black hue on the face of the panels.
Bi-facial solar panels produce power from both the front and back ‘faces’ of the solar panel. While both the poly and mono panel technologies are ‘monofacial’, bi-facial solar panels leave the rear of the panel exposed so that light can reach the solar cells from both directions. The result is a highly efficient solar panel that has increased durability due to the UV resistance on both sides of the panel. The technology used in bi-facial panels is generally monocrystalline, though there are some polycrystalline bi-facial solar panels on the market.

P Type vs N Type

All crystalline solar cells (mono and poly) are made using a very thin wafer of base silicon with the two main types being p-type and n-type. These are made when the silicon is ‘doped’ with specific chemical elements to create a positive (p-type) or negative (n-type) charge.
N-type silicon cells are more expensive to manufacture but offer higher performance and a lower rate of light induced degradation, plus an improved temperature coefficient.
