The low-concentrated PV (LCPV) plantss

The company has developed and manufactured several types of LCPV plants based on solar modules with two-way sensitivity.

1. SEU 4000K

SEU 4000K is a plant with optical concentrators on 16 modules with bifacial sensitivity. An optical concentrator and modules are installed on a tracker that tracks the position of the sun in the polar coordinate system.

Technical characteristics in light conditions P = 1000 W m2; t = 25 ° C, AM 1.5:

1. Peak power of LCPV plant, not less than, Wt – 4000

2. Weight of LCPV plant, not more than, kg. – 1200

3. Aperture of LCPV plant, mm – 5500 x 8000

4. Angle of azimuth (variants), deg. – from 0 to 45

5. Maximum tracking angle, deg. – ± 60

6. Accuracy of the sun tracking, not more, deg. – ± 3

7. Recovery time, not more, min. – 30

8. Operating ambient temperature, deg. – -30 +55

9. Max. wind speed with installed solar modules, not less, km/h – 140

10. Lifetime, not less, years – 10

The power increase of LCPV plant with the use of solar modules with bifacial sensitivity is 3-7%.

2. SEU 1000KD, 2000KD, 3000KD

Plants are available in accordance with the patent № 2406043 RU. The plant also includes a tracker for the position of the sun tracking. In the plant used the set of customization possibilities of solar modules with bifacial sensitivity is used that allows you to get on a solar module, with standard size 1600x1000 mm, peak power of 500 Wt.

3. The low-concentrated PV plants with efficiency more 50%
The LCPV plants on the bifacial cooled modules with recovery of heat generated by solar modules is in development.
The LCPV plants has the following competitive advantages in relation to the existing solar PV systems:
- Operation at high ambient temperatures (up to 55 ºC), at it the temperature of PV module will not exceed 85 ºC;
- High specific power of the module, more than 340 W per m2 at ambient temperature of 25 ºC;
- Heat recovery is possible. The flow of cooling liquid with temperature of 70 ºC is 690 l/hour;
- The efficiency of the solar cell by the total (electrical and thermal) peak power - 70%;
- Less total cost per watt of generated electric and thermal power of  LCPV plant.
