Review of Jinko Solar 310W Poly Solar Panel

Categories: Review and Solar PV Panels.

If you are looking at solar panels for your home, consider the JinkoSolar 310W Poly solar panels as part of your solar electricity generating system. 

JinkoSolar 310W Poly solar panel

There are some things you might keep in mind. JinkoSolar panels have been around for a while. They’ve been manufactured in China since 2006. The company has a global export reach to 23 countries.


The model of JinkoSolar we reviewed below is the 310W Poly SLV/WHT 1000V Solar Panel. JinkoSolar 310W Poly solar panels are sold on Amazon in packs of 4. 


JinkoSolar 310W Poly Solar Benefits

JinkoSolar's 310W Poly solar panel is a 60 cell panel. (Their 72 cell panel (JKM315PP-72) Poly Solar Panel power production is just a notch higher at 315Wp).

  • This is a polycrystalline cell
  • They are certified to withstand high wind loads (2400 Pascal) and high snow loads (5400 Pascal)
  • They have a 10-year product warranty and 25-year performance warranty
  • The JinkoSolar 310W Poly solar panel offers efficiency rates of up to 16.5%

If you have ample roof space the return-on-investment with a lower efficiency array may be irrelevant. JinkoSolar panels will be a cost efficient choice if you can fit enough of these panels on your roof. They will meet your power needs at a reasonable price. That assumes the installed price remains proportionately lower compensating for a higher unit price of higher efficiency panels.


Compare the lifetime value of JinkoSolar panels against other similarly priced or similar output brands. JinkoSolar panels are high on quality ratings. Do your cost analysis before making your final buying decision. Remember that more panels will need more racking and labour to install.

JinkoSolar 310W Poly Solar Panel Quality

JinkoSolar was the first Chinese manufacturer to receive the Qualification Plus (Q+) certification. TÜV Rheinland's Positive Quality™ Program promotes solar PV module brands proven to meet their high manufacturing quality standards.


TÜV Rheinland does independent certification for solar modules. To be able to install solar panels in most countries, the panels need to meet IEC61215 and IEC61730. Q+ by TÜV Rheinland is a rigorous test, particularly for mechanical robustness. It also tests hot spots, insulation and wet-freezing cycle.


By all means compare the solar panels from many of the top solar companies but do those comparisons fairly. The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is Australia's national science agency. CSIRO did a full year of independent consumer tests using their facilities in Newcastle. This means this panel was being assessed for Australian coastal weather conditions. They tested ten solar panels and their independent testing showed the JinkoSolar 310W Poly solar panel came second overall. It was one of the two modules to receive an “excellent” performance rating. It was better than all other modules in its price range.


The JinkoSolar 310W Poly solar panel has excellent low-light performance. They also have high-heat tolerance compared to other popular brands within the CSIRO test. Most fixed panels spend more time in lower light than in direct lighting conditions of STC. The testing chamber for Standard Test Conditions (STC) are in laboratories. They found JinkoSolar's 310W Poly solar panel performs well on practical rooftop conditions. It had a higher output at Nominal Operating Cell Temperature (NOCT) than many panels in the test.


What People Had To Say

We looked at what people had to say about the JinkoSolar 310W Poly solar panel. Most customers shared that they had good experiences with the installed panels.


Customers were impressed that they didn’t experience problems with the installation in their first year. They also liked that they can check the output knowing whether they have power going to the house or the grid.


Some customers commented that they liked the appearance of ​JinkoSolar 310W Poly solar panels on their roof, and were confident with the warranties given. With this investment, buyers got savings without worrying about too many lifestyle adjustments.


A lot of the reviews I have read about this panel were positive for the most part. A few customers did leave some negative feedback. Some negative feedback was about their experience with their panels. Those customers were disappointed that they had not installed sufficient generating capacity. They said that despite getting energy savings they still got monthly utility bills. This means they were generating less power than they used as they had underestimated their power need.


It’s worth pointing out that there were only a few people with this problem and not due to shading. It could be an issue with particular lot and roof orientations not being at optimum. Also, the array installation size might not have fully considered all household electrical loads. This is an important part of the design required before buying the solar system.


Our Recommendation

There are many solar panels available on the market.  The JinkoSolar 310W Poly solar panels stand out on price and test performance. This particular Poly 60 cell panel is a steady robust unit that have the same kinds of specification as others costing more money.


We like this JinkoSolar 310W Poly solar panel because it's designed well. The Chinese manufacturer has a history of checking its quality. It's also acknowledged as a manufacturer adopting innovation in this industry. If you’re looking for a low price point solar panel and a brand with a good reputation then this unit hits a sweet spot. The units are well made from high quality, durable materials. 


This Jinko Poly solar panel is a great option at their price and are well worth buying for installation.
