It is the main such framework that scores solar makers across a wide scope of target models.
The scoring framework has been figured get-togethers conversation with industry pioneers and offers a straightforward and impartial scoring approach for solar brands. It has been utilized interestingly to score the SolarReviews 2021 Top 20 Solar Panel Manufacturer Rankings.
The rankings are intended to give property holders insight into the probable quality and execution of solar panels over their full life. The term ‘full life’ is key here, as solar panels are a drawn out investment with a warrantied life of between 25 to 30 years.
For what reason was a specialist scoring framework required for solar panel producers?
In the wake of running a surveys site for the solar industry for a long time, it was obvious to our publication advisory group that buyer audits alone were sufficiently not to offer reasonable guidance to customers about their decision of solar panel brand. A specialist rating framework was expected to pass judgment on measures not apparent to customers.
We don’t simply pass judgment on a maker’s present product offering, yet additionally its financial wellbeing, the probability it will be around over the course of the following 25 years to respect guarantee claims, and the nature of the solar panel installation companies that decide to install each brand. (Shopper audits, however helpful as they seem to be, are ordinarily composed within the principal year of the panels’ life, and accordingly aren’t as great at predicting solar panels’ exhibition over the long haul).
Peruse on to see the full rundown of ranking variables, alongside clarifications of why they are critical to mortgage holders and how each was scored.
The appraisal was led dependent on realities and information accessible as of June 30, 2021.
The following is a rundown of the standards we used to pass judgment on solar panel companies and the loads we allocated to each.
Worth (30%): Solar panels are a considerable investment, and their high forthright expense deflects numerous property holders from going solar. In that capacity, we think solar panel cost is a huge factor to think about when rating solar panels.
Module quality (20%): This is an evaluation of the spec sheet execution of each organization’s top private solar panel, explicitly their productivity rating and temperature coefficients. Panels that occupy less room and perform all the more reliably in various climatic conditions will procure a higher score.
Financial perceivability and strength (20%): This factor evaluates the financial wellbeing of the solar panel maker. This fills in as the most ideal indicator of whether the organization will be around to respect any guarantee guarantees that might emerge.
Guarantee (10%): Here, we take a gander at both the item and execution guarantee. The previous mirrors the unwavering quality of the module, while the last discloses to you how panel execution will hold up as time passes.
U.S. investment (10%): This factor evaluates how dedicated each brand is to the U.S. market.
Vendor organization (10%): This mirrors the accessibility of the brand among solar installers.
How about we bring a more profound plunge into every class and perceive how we doled out scores for each.

1. Worth – 30%
Points alloted for: Cost per watt
To ascertain the incentive of each solar panel brand, we doled out points dependent on the expense per watt of their lead solar modules as of the hour of scoring (June 30, 2021). The lower the expense per watt, the higher the score.
Comparing solar panel brands dependent on cost per watt is the norm in the solar industry. Cost-per-watt figures are helpful as they permit a like-for-like correlation between solar panels of various force yields, For instance, a 6,000 watt framework worked of 20 x 300-watt panels, or 15 x 400-watt panels; instead of comparing the expense per panel, looking at the expense per watt is considerably more meaningful.
We tracked down that the solar panel brands offering the best worth (AKA the least expensive) were generally half as costly as the brands offering the most reduced worth (AKA the most costly).
Most noteworthy scores for esteem: JA Solar, LONGi, Yingli, Axitec
Most reduced scores for esteem: SunPower Maxeon, Panasonic, Solaria, Seraphim, LG Solar
2. Module quality – 20%
Points relegated for: Panel productivity; Temperature coefficient
When judging module quality, we chose to zero in on the two most significant things on the determinations sheet: panel proficiency and temperature coefficient of Pmax. Each factor represents a large portion of the complete points in this class.
Solar Panel Price estimates the measure of daylight that gets changed over into energy. A panel with a higher effectiveness rating requires less space to create a given measure of energy, reducing its actual footprint, or taking up less space. (We have an inside and out blog explaining panel effectiveness here).
Temperature coefficient of Pmax reveals to us how well a panel will act in true temperatures. The lower the temperature coefficient, the better – as this implies there is less force misfortune for each 1°C that the panel is more sultry than 25C. (Panels run about 20°C more sweltering than the surrounding open air temperature, so your panel will in all likelihood be running at higher than 25°C for the greater part of the year).
These two elements are not only meaningful all alone; they additionally address the solar panel system general creation quality. For an organization to accomplish high effectiveness rating and low temperature coefficients, they need to utilize progressed, profoundly mechanized manufacturing measures.
Most elevated scores for module quality: LG Solar, SunPower Maxeon
Least scores for module quality: Hyundai, Boviet
3. Financial perceivability and strength – 20%
Points alloted for: Public listing; Availability of financial articulations; Operating income and benefit
This classification could similarly too be called, ‘How probably is it that the solar panel maker will be around for the following 25 years?’
This inquiry is significant on the grounds that solar panels are a special item – they are intended to work for quite a long time, and makers ensure a certain degree of execution for a time of 25 years.
We answer the inquiry by looking at a few indicators of financial wellbeing.
The initial step is to determine whether the organization’s financials are noticeable, and accordingly simple to survey. Companies that distribute their financial assertions, or are traded on an open market, get more points.
Then, we take a gander at income. We relegate points to companies dependent on the size of their general income, as we consider bigger producers bound to endure. Enormous producers with income north of $2 billion acquire the greatest number of points, while more modest players with under $100 million in income procure the least.
Finally, we take a gander at benefit. We dole out additional points to companies that detailed a net benefit in the latest financial year. The rationale here is basic: companies that are productive have the most obvious opportunity with regards to staying in business and expanding, while those that are unfruitful have less ruddy future possibilities.
A portion of the makers we’ve appraised are private or completely possessed auxiliaries of bigger gatherings that offer zero ability to see into their financial position. Where this was the situation, we took a gander at the financials of their parent organization, however limited these scores significantly. Our rationale is that while an auxiliary can profit with the assets of the parent organization, and merits a few points for being essential for a huge as well as productive organization, an auxiliary is additionally in danger of being turned off in case it isn’t beneficial.
Most elevated scores for financial perceivability and strength: LG Solar, QCells, LONGi, Jinko Solar, Canadian Solar, JA Solar, Trina Solar
Least scores for financial perceivability and strength: Silfab Solar, Axitec
4. Guarantee – 10%
Points doled out for: Product guarantee length; 25-year execution guarantee
The producer’s guarantee is a significant thought when buying an item like solar panels, since they are totally solid for 25 years or more.
With regards to item guarantees, we’ve granted higher points to the brands that cover the most significant length of time periods, for example between 20 to 30 years. [We examine the guarantees of leading brands in this article].
For the exhibition guarantee, we’ve additionally allocated the most elevated points to solar panels that have the least debasement rates, which implies they will see the littlest yield drop-offs over their warrantied lifetime. The panels that scored most elevated here indicate that they will deliver 90% or higher of their appraised yield at the 25-year point.
You might be wondering why we’ve chosen to restrict the weightage of guarantee in our scoring framework to simply 10%. The explanation is straightforward: while guarantee guarantees are valuable, we accept that the organization’s capacity to respect the guarantee is the main thing, a reality which is best reflected by their financial perceivability and strength score.
Most noteworthy scores for guarantee: SunPower (Maxeon), REC Group, Panasonic, LG Solar
Most reduced scores for guarantee: Hyundai, S-Energy, Boviet, Yingli
5. U.S. investment – 10%
Points appointed for: Headquarters or workplaces in the U.S.; American manufacturing; Attendance at U.S. career expos and occasions
Numerous buyers place need on buying nearby and supporting the neighborhood economy. Accordingly, we’ve appointed more points to companies that have their worldwide central command in the U.S., with lesser points on the off chance that they just have workplaces here. We likewise granted additional points to makers with solar panel creation offices here in the U.S., just as for ongoing participation at significant American career expos and industry occasions.
The companies that score most elevated in this class are American-settled companies with nearby creation offices. In any case, some enormous unfamiliar producers score somewhat exceptionally also, having burned through hundreds
