Photovoltaic electricity source


There has been suggested an ecologically friendly AC electricity source which works for the account of transforming electrical magnet solar radiation and could be used in standalone mode.

PV unit consists of PV panels’ set, an accumulator (electrical and chemical), a controller, an inverter, a set of connecting cables and switching equipment. Panel construction allows setting variable angle tilt to the horizon. The accumulator has got a frame with controller and inverter on it as well as there are handles for carrying purposes.

The unit construction is suitable for commercial use.

Innovative Aspect and Main Advantages

The suggested PV unit has got some advantages comparing to other stand alone power sources, like petrol station, etc.:

  • Noiseless, ecologically clean production energy;
  • Comparatively simple assembling system, and simple preparation to work in remote areas (far from traditional power systems);
  • Absence of negative effect on environment;
  • “compactness” when transporting and assembling;
  • Options to enlarge capacities by adding new panels;
  • Regulating unit productive output due to panel variable angle tilt to the sun.

Areas of Application

The unit can be used as local power source for remote consumers; the last can be involved in any production type or leave in recreation zones. Considering high quality of generated power the unit can be used for any load capacity equipment

Stage of Development

An experimental unit has been made: installed capacity - 200 W, inverter – 600 W, output voltage – 220 V, frequency – 50 Hz. It has been tested in laboratory. Technical project and technical documentation have been developed already. The unit can be scaled easily.
