The experimental results show that the above-mentioned method can be used not only as estimative analysis but also as quantitative analysis of mechanism balance.

At the same time, as a result of limitations of investigation and basic financial data of the project is estimative and forecast able, financial evaluation has unavoidable limitation.

This dissertation mainly research solar power generation, using the measure of current pre-estimative arithmetic and voltage double-loop control to improve the wave of output current and voltage ;
