Applications of PV-T Solar water heaters ( Both of independent or grid-tied style )


Solar heat system for slopping roofs

Many roofs are based on slopping roofs, therefore, either flatbed solar collector or PV-T optical water heater goes well with slopping roofs. In addition to enhancing the appearance and using the space well, it can prevent the roofs from direct sun irradiation.
