Solar Panel Reviews
Here at reneenergy.com, we collect information from various sources and recommend online tools and knowledge to make the initial decision to decide to go solar or not. We recommend solar panel calculators because of their capability to provide you with reasonable estimates, although not exact figures. Hence, it is upon the user to get with their solar developer or solar installer to get more actual data before they make the final decision to go solar.
When it comes to solar panel reviews, no size fits all when it comes to selecting the best solar panels for your home or business. Users are different and have different needs and want based on their specific design requirements, solar potential, budgetary requirements, financing, solar panel costs and other specific considerations that a user might want to factor in.
In the article, the best solar panels, we noted that the EnergySage Marketplace had developed ranking criteria that can be used to rank different solar panels based on three aspects of solar panels, including solar panel efficiency, temperature coefficient, and solar panel warranty.
These factors are a good starting point and can be used to compare different solar panels from different solar manufacturers or solar brands among other aspects of solar panels such as real field data that capture the performance and reliability of different solar panels.
A good starting point to assess whether This can help to answer questions like are these solar panels reliable in the field, do we have reports of system failures and so on as captured below.
Our solar panel reviews will capture the above factors (i.e., solar panel efficiency, temperature coefficient, and warranty) and other aspects to enable users to make the initial questions of going solar such as:
- How many solar panels do I need?
- How much solar electricity can I produce on my rooftop?
- How much do solar panels cost?
- How to go solar today? etc
Solar panel reviews provided here also provide links to solar manufacturers data sheets to enable users to base their judgment on technical specifications provided by the solar manufacturer. Solar panel data sheets are usually located in the websites of most solar panels manufacturers and are a great source of information relating to electrical data, test and certifications, operating conditions & mechanical data, warranties for materials as well as solar panel efficiencies. This data is useful in informing solar design, solar electricity production, and other aspects relating to a solar PV system.
Solar Panels Performance of Different Brands.
Furthermore, when talking about solar panel reviews, we should consider the performance of different solar PV models and brands in the field. However, there is not enough field data to make more informed conclusions and base our judgment on what brands seem to be performing well according to DNV GL Releases The 2017 PV Module Reliability Scorecard. According to DNV GL, there is about 300 GW of installed global PV capacity while about 78% of this capacity has been in the field for less than five years and hence, it should take more than 20 years from now before actual lifetime field data for the majority of today’s capacity is collected.
As such, this presents a data challenge when it comes to solar panel reviews and knowing what solar manufacturers or brands have the best performing solar models, and that is reliable based on the actual data on the ground. By breaking this barrier, this will be useful information to solar investors, solar developers, as well as anyone who desires to get the best solar panels for their business or their homes. This information is essential especially in this day and age when the cost of solar panels is reducing at a faster rate; hence increased competition among solar manufacturers that might lead to compromising quality at the expense of reducing the solar panel price.
At the moment, there are hundreds of solar panel manufacturers with different factories in different places and this means some brands may want to manufacture the cheapest solar panels at the expense of the price to be able to compete in the market. These are the issues that systems like DNV GL are trying to solve using their PV Module Reliability Scorecard. The DNV GL PV Module Reliability Scorecard aims to address this critical challenge, and with its supplier specific performance analysis, the scorecard can help investors and developers generate quality-backed procurement strategies to ensure long-term project viability.
DNV GL Report
Besides, the DNV GL report notes that field failures of PV equipment can stem from materials issues fundamental product design flaws, or faults in quality control during the manufacturing process. DNV GL gathers data from its lab from a large group of panel manufacturers and has been testing solar modules for more than six years and has accumulated a lot of historical data.
According to the report, a good quality management strategy should help to avoid procuring equipment that exhibits early lifetime failure and to select a PV system that performs successfully over the long-term because nowadays there are hundreds of PV modules globally active today. These solar manufacturers have different or utilize a broad range of materials, manufacturing techniques, and quality control techniques that can result in various or a wide range of solar panels quality as well as reliability.
