Net billing is a modern self-consumption energy framework designed for homeowners who install photovoltaic systems to directly combat rising electricity costs. Under this scheme, the energy your solar panels produce and that you consume in real-time during the day directly offsets your retail electricity rate, maximizing your immediate savings. Any excess solar energy you do not use isn't lost; instead, it is exported back to the national grid and credited to your account at a lower but competitive wholesale market price. This dynamic system ensures a highly transparent approach to tracking the true value of your self-produced electricity while supporting grid stability.
