IDEA #8E4Y7N Photovoltaic Electricity Source

APPENDIX OOFF INNOVATIVETECHNOLOGIES • SOLARTECHNOLOGY AND PHOTOELECTRONICS PHOTOVOLTAIC ELECTRICITY SOURCE Description There has been suggested an ecologically friendly AC electric(cid:2) ity source which works for the account of transforming electri(cid:2) cal magnet solar radiation and could be used in stand(cid:2)alone 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. Innovation 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. Application fields The unit can be used as local power source for remote con(cid:2) sumers; the last can be involved in any production type or leave in recreation zones. Considering high quality of generat(cid:2) ed power the unit can be used for any load capacity equipment 192 Picture.1. Unit scheme Development stage An experimental unit has been made: installed capacity (cid:2) 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.
