The low-concentrated PV (LCPV) plants
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:

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%.

3. The cogeneration low-concentrated PV plants
The LCPV plants on the bifacial cooled modules is developed.
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 80 ºC;
- High specific power of the module, more than 340 W per m2 at ambient temperature of 25 ºC;
- Getting a heat in the form of hot water;
- 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.

* With a solar cell efficiency of 22.7%.
All types of solar systems have a system for tracking the position of the sun in polar coordinates. This system increases the production of electrical and thermal energy by 28%, which is equivalent to an increase in the total peak power by this value.
Under the agreement No.94GRNTIS5/26065 with the Foundation for the Promotion of the Development of Small Forms of Enterprises in the Scientific and Technical Sphere, in 2019 design documentation was developed, a prototype of a cogeneration unit was manufactured and tested.
