Abstract：Taking a photovoltaic project in Yajiang asanexample，theinfluence of adjustable photovoltaic brackets on the power generation effect in terms of adjustment frequencyand adjustment accuracywas studied，and the comparison results of theannual irradiance of the module surface using five adjustment strategies，including fixed，2 times per year，4 times per year，monthly automatic adjustment and hourly automatic adjustment，were obtained.The calculationmethodoftheoptimalnorth-south inclinationangleof theadjustablebracketmoduleandtheirradiance onthe surface of the module was given，and the irradiance calculation model of theadjustable photovoltaic bracket was established，which providedareferencefortheselectionof the adjustment strategyof theadjustable photovoltaic bracket.Accordingtothecalculation，if theprojectadoptsautomaticadjustable photovoltaic brackets，theanual irradiation on the surface of the module will be significantly improved.
