In this paper we present a model, which have been developed for the estimation of the PV products’ cells’ performance in an indoor environment. The model computes the efficiency and power production of PV technologies, as a function of distance from natural and artificial light sources. It intents to support designers during the energy stability calculations, while creating PV-integrated products for indoor use. For the model’s validation, we tested indoors the PV cells of 10 commercially available PV-powered products in the power range of 0.8mWp to 4mWp, under three types of artificial illumination (halogen, fluorescent, LED lights) and natural light. Due to the model’s purpose to support the design process, its accuracy is not required to be high. Besides, given the difficulty to precisely measure low irradiance (< 20 W/m²) up to this point, it is unmanageable to succeed precise results. The measurements’ analysis revealed that the model could sufficiently predict PV products’ cells’ performance under CFL, LED illumination and mixed indoor light with a typical error around 25%. Measurements showed that under typical mixed indoor irradiance of up to 20 W/m², a-Si cells’ efficiency ranges between 5-6%, c-Si cells’ between 5- 7% and mc-Si cells’ between 4-6%.
