C. Solar-Biomass Hybrid Systems

Solar-biomass hybrid systems combine solar energy with biomass as a backup fuel source. Biomass can be used to generate electricity or heat when the solar panels are not producing enough power. This combination can reduce the consumption of fossil fuels and provide a more sustainable energy solution. Biomass can be sourced from agricultural waste, forest residues, or dedicated energy crops.

D. Solar-Storage Hybrid Systems

Solar-storage hybrid systems combine solar panels with energy storage systems such as batteries or pumped hydro storage. The energy storage system stores excess electricity generated by the solar panels during the day and releases it when needed, such as during peak demand periods or at night. This combination can provide a more reliable and flexible energy supply, reducing the reliance on the grid and increasing energy independence.
