What are the different types of hybrid solar power systems?
Hybrid solar power systems vary in performance & utility based on the type of hybrid solar inverter used in the system. Most systems using a standard hybrid solar inverter or, all-in-one hybrid inverter, are designed to feed the solar energy generated by the solar panels to the loads connected to the inverter (known as connected loads). The solar capacity & battery storage in such a system are optimized to cater to most of the daily energy required by the connected loads, thereby avoiding any solar energy going waste.
More advanced solar hybrid systems use a more expensive bi-directional solar hybrid inverter that has an additional feature of being able to export excess solar power, i.e. if the power requirement of the connected loads is met & the battery storage has been charged to full, excess solar power can be either fed to the other loads (those not connected to the solar inverter), or, exported back to the grid. Approvals from the Utility company are required for installing these type of systems similar to those required for a grid-tied solar power system.
