Likely increase in performance of your panel compared to a panel with the least favourable choices for all the parameters. Performance is an indicator of both qualitative aspects such as reliability and quantitative aspects such as generation.
The benchmark generation is the generation of the solar panel with the least favourable choices for all the parameters.
The benchmark cost is the cost of the solar panel with the least favourable choices for all the parameters.

Solar Panels

Electricity producing unit in a solar plant

A solar panel converts sunlight to electricity. It is an assembly of solar cells that absorbs sun’s energy and converts it into electric current. Solar panel is the most important component of the solar plant and its selection has the highest significance on the overall performance of the plant. Each and every aspect of the panel needs to be carefully chosen in order to ensure optimal output from it.

1. What range of power tolerance does the panel have?

Positive tolerance ensures expected power is generated at standard conditions

.A positive tolerance ensures that at standard conditions the generation from panels is equal or greater than its rated power. Negative range for tolerance indicates that the generation can be lower than the specified power rating
Data is available in the datasheet

2. What module efficiency range does the panel have?

Higher the efficiency, lower the area required for same yield.

.A high efficiency panel stands for a high quality manufacturing process and requires less area than a lower efficiency panel for the same output.
Data available in the datasheet of the panel

3. What is the nominal operating cell temperature of the panel (NOCT)

Lower the NOCT, better the performance in high temperatures

.NOCT indicates the temperature developed within the solar cells at realistic atmospheric conditions. Lower NOCT indicates a lower dependence on outside temperatures which gives a better output
Data is available in the datasheet

4. Does the panel have an Anti-PID or PID Resistant feature?

Anti-PID feature reduces the likelihood of panel degradation

.PID effect refers to the degradation of panels which occurs due to stray currents. This can cause up to 30% performance output loss in the first year.
If the feature is present, it will be specifically mentioned in the datasheet. If you can't find it, please enter the choice as "No".

5. Is the panel warranty covered by an insurance provider?

Third-party Insurance is to guard against the panel maker going out of business

.A Third-party Insurance from reputed companies can offer warranty solutions for the panels. A third-party insurance will prove useful when the product manufacturer is not able to honor the warranty provided by it.
Data is available in the datasheet

6. Does your panel offer a high performance at low irradiance?

A high performance at low irradiance ensures a higher average output

.Panels that promise a high performance at low irradiance can have a relative high efficiency levels even at low irradiance levels of around 200 W/m2
If the feature is present, it will be specifically mentioned in the datasheet. If you can't find it, please enter the choice as "No".

7. What is the protection rating of the module junction box?

Higher the IP number, greater the resistance to water and dust

.IP 67 protection ensures that the junction box is completely resistant against dust and temporary immersion in water.
. IP 65 is a lower level of protection against these factors
Data available in the panel datasheet.

8. What type of performance guarantee does the panel offer?

Higher yield more likely with linear guarantee

.Standard Guarantee usually comes as a two-slab guarantee - 90% performance guaranteed for the first ten years and 80% for the subsequent 15 years.
. Linear Performance Guarantee typically comes with a degradation of around 2.5% in the first year and a linearly decreasing performance (about 0.7%) from then on.
Data available in the datasheet of the panels

9. Is the glass used in the panel of high transmission/with anti-reflective coating?

Anti-reflective coating ensures lower energy loss and higher output

.Glass with anti-reflective coating ensures that the energy lost by light reflection from the panels is reduced by 3-4%
If this feature is present, it will be specifically mentioned in the datasheet. If you can't find it, please enter the choice as "No".

10. What is the maximum power temperature co-efficient of the panels?

A low value ensures better performance in high temperatures

.Should be as small a value as possible to minimize output losses with increase in temperature beyond 25 deg C
Data available in the datasheet of the panels
