Bifacial solar panel JA Solar 575W silver frame jam66d42-575 / mb

Benefits of the solar panel JA Solar 575W JAM66D42-575 / MB

JA Solar it is one of the largest manufacturers of photovoltaic modules of the world, and the range DeepBlue 4.0 Pro it is your bet for large format facilities. The JAM66D42-575 / MB it is designed for projects in which each square meter and each euro of structure count: by concentrating 575 W in a single module, the number of panels, staples, rails and hours of mounting by KWP installed is reduced.

Bifacial production: extra energy from the back face

The big difference of this module in front of a monofacial panel is in its transparent back glass. Thanks to a 80% bifiality ± 10%, the back face takes advantage of the light reflected by the ground or the deck. The card itself JA Solar quantifies: with a 10% rear irradiance ratio of 10%, the model of 575 W delivery 621 W, that is, some 46 W Additional by Panel (approximately 8% more).

This gain is greater the more reflective the surface is under the module: covers with white sheet, , clear gravel or concrete floors favor rear production, especially in facilities on high or tilted structures where light comes without obstacles to the back.

N-TYPE technology with low degradation and less heat losses

Cells n they present a light-induced degradation (Lid) Very reduced faced with the ancient P-type cells, something that is reflected in the power guarantee: 1% degradation the first year and a 0.4% per year for 30 years, which leaves the power guaranteed in the 87.4% at the end of the period. According to the comparative curve of JA Solar, a standard module would stay at the 83.1% in the same period, a difference of more than 4 points of guaranteed production.

The temperature coefficient of -0,300%/°C limit the loss of power in summer. By way, with the cell 65 ° C (40 ° C above STC conditions), the theoretical loss would be from 12%, a remarkable behavior for a module of this size exposed to the midday sun in Spain or Portugal.

16BB technology and better response with low light

The 16 busbars (16bb) they shorten the path of the current within each cell, reduce resistive losses and make the cell more tolerant to microfixes. JA Solar highlights a best answer with low irradiance, which translates into more useful hours of production at sunrise, at sunset and on cloudy days.

Where to install the JA Solar JAM66D42 575W?

Flat covers and industrial ships

With 2278 x 1134 x 30 mm and 31.8 kg, this panel is designed for installations commercial and industrial self-consumption on flat or sheet metal covers, where it is mounted on structures for solar panels triangular or inclination that let the light pass on the back face. The load on the cover is one of some 12.3 kg / m² by the weight of the module, not counting the structure.

Solar orchards and soil structures

In ground plants, the high-power format reduces the number of strings and field wiring. The maximum system voltage of 1500 V DC it allows long series and, therefore, less connection boxes and less losses in direct current.

Pergolas, Marquee and Carports

The double glass of 2.0 mm lets part of the light between cells and take advantage of the reflection of the soil, which converts this module into a good option for photovoltaic pergolas and parking marquees.

Inverters compatible

With a IMP of 14.30 A in STC and one ISC from 16.37 A with a 10% rear gain, it is convenient to choose inverters solar with MPPT inputs prepared for high current modules. In self-consumption projects with storage inverters hybrid three-phase combined with lithium batteries they allow you to move the production of noon at the pizes of consumption.

Orientation sample of Strings sizing

On VOC 47.98 V and a vOC coefficient of -0,260%/°C, to -10 ° C the open circuit tension of each module would rise up to some 52.4 V. With a inverter of 1000 V DC they could theoretically connect up 19 modules in series, and even 28 modules in systems 1500 V DC. The final dimensioning should always be validated with the MPPT window of inverter and the minimum historical temperature of the site.

Frequently Asked Questions (FAQ)

1. How much extra energy does the back face of a bifacial panel contribute?

It depends on the reflectivity of the surface and the mounting height. JA Solar indicates that, with a 10% rear irradiance of the front, the jam66d42-575 / Mb goes from 575 W A 621 W. On white surfaces or clear and with the high module, the gain may be higher; On a roof coping stuck to the cover, it will be very reduced.

2. Is it a good panel for the roof of a home?

For its size (2.28 m long) and its weight (31.8 kg), is mainly thought for flat covers, , industrial buildings, , solar orchards and pergolas. For inclined residential roofs are usually more practical modules of smaller format, or a solar kit complete already dimensioned for domestic self-consumption.

3. What connectors carry and are compatible with MC4?

The module incorporates connectors QC 4.10-35 / MC4-EVO2A, compatible with the MC4 standard and certificates for even systems 1500 V DC. To guarantee the sealing and the validity of the guarantee, it is recommended to always connect with connectors from the same manufacturer and model.

4. What inverter do i need for these panels?

The inverter you must admit at each MPPT input at least the short circuit current with bifacial gain (16.37 to 10%) and a string voltage compatible with the VOC corrected by temperature. The inverters networking trade range three-phase are usually prepared for high current modules like this.

5. What guarantee does it offer JA Solar in this module?

12 years of product guarantee facing manufacturing defects and 30 years of linear power guarantee, with a maximum loss of the 1% the first year and from 0.4% annually subsequently, which assures at least one 87.4% of the initial power in the year 30.
