COMPLEX EVALUATION MODEL OF A SMALL-SCALE PHOTOVOLTAIC INSTALLATION PROFITABILITY

Аннотация

Abstract: Number of small-scale photovoltaic installations grows rapidly every year. A decade ago,
this was motivated solely by the attempt to reduce greenhouse gas emissions, because the investment itself
was not economically viable. Nowadays, the table is turning. Small-scale installations are becoming
profitable, if selected wisely. Therefore, the article discusses, what are the factors that need to be taken into
consideration when selecting the photovoltaic installation, what data must be collected beforehand and how
to proceed in their analysis. To sum up, the article provides an in-depth methodology for the small-scale
photovoltaic installation assessment that is aimed to be used in household's or small commercial consumer's
profitability appraisal of such an investment.
