Abstract

The existing renewable technology in use, particularly solar PVs for homes and other buildings, is billed 

as a significant step towards providing more robust, secure and affordable electricity. However, unavailability

 of electricity buyback programs in many regions, and recent changes in buyback policies in some countries 

make solar costlier due to the need for extra storage in the system. To this end, we present our system 

called SMaRTI: Self-Managing Renewable Technology Integration. This system is mainly designed for places 

where the utility grid is available, but for various reasons any excess electrical energy cannot be put back 

onto the grid through buyback programs. In traditional hybrid or grid-tied PV systems with battery backup, 

the electrical energy from the PV and the grid are tied at the inverter output. However, in SMaRTI this 

tying up is carried out at multiple distribution points in the system, giving SMaRTI an opportunity to optimize

 the PV output more efficiently. By using SMaRTI, not only one can utilize up to 98% of electrical energy 

generated by PV system but also the cost of ownership is reduced by more than 40% over a ten years period.
