As data from more sensitive detectors became available at hard X-rays, cm-to-mm-waves, they show convincing indications that the bulk of energy content of solar bursts might be conceived as a response to multiple energetic injections. Measurements at cm-mm-wavelengths well correlated to hard X-rays, which suggest a proportionality of the total burst energy content to the number of energetic injections at both ranges. The explosions might in fact be the result of a composition of smaller, simpler, fast and highly energetic processes at their origin, produced at various rates. Large and small events would arise from larger or smaller number of injections. They would not be distinguished by the energy release rate of the primary conversion mechanism, which appear to be the same for different flare importances. Electrons accelerated to tens of MeV shall produce spectra with emission in excess in the mm- submm- waves range. For higher energies these particles might produce a genuine far infrared spectral component, which characteristics will become better described with the results expected from the new Solar Submillimetre-wave Telescope(SST), recently installed in El Leoncito, Argentinean Andes.
