Is Ongrid solar system or Hybrid system better?
A grid-connected solar energy system, also known as a grid-tie or grid- interactive system, is a type of solar panel system that is connected to the electrical grid. These systems use solar panels to generate electricity, which is then used to power your home or business. Any excess electricity that is generated is sent back to the grid, and you can earn credits or compensation for this excess energy. WAPDA currently as of January 2023 pays PKR19.32 per excess electricity unit exported to the grid. An ongrid Solar system has low maintenance, is cheaper to install and reduces your WAPDA bill to almost PKR 0.
A hybrid solar energy system, also known as a hybrid photovoltaic system, is a type of solar panel system that can operate either off the grid or connected to the grid. These systems are designed to provide a backup power battery in the event of a power outage or grid failure. Hybrid systems can either use a battery bank to store excess energy or they can be connected to a generator. The benefits of Hybrid system are they provide battery backup and even produce solar energy to charge the batteries during WAPDA outages. Hybrid systems also have negative points as they are more expensive then ongrid systems, require regular maintenance and do not reduce your electricity bill to dramatically as excess energy is stored in batteries rather than exporting to the grid first which does not reduce your electricity bill.
Both ongrid and hybrid solar energy systems can be effective ways to generate clean, renewable energy, but the best choice for you will depend on your specific energy needs and goals. If your goal is to reduce electricity bill to 0 then our recommendation is to go with ongrid system but if your goal is to have uninterrupted power then we recommend to go with Hybrid system. It's a good idea to consult with BMY Renewables professional site visit team to determine the best system for your home or business.
