Whether you want to enjoy living in a house or working in an office that uses grid-connected solar panels or off grid solar panel is up to you. In India, much of the solar power plants in urban/semi-urban or even rural areas; are setup set upid connected/tied configuration owing to their proximity to the grid, including rooftop solar panels, and solar arrays at solar parks. It is only the remote locations that is remote settlements or villages/observation stations/security posts located in forested areas/deserts/islands/ barren lands/mountains that are far off the power grid that solar photo voltaic panels are setup in off grid configuration.
Advantages of Grid-Tied Systems
1. Save more money with net metering
- A grid-connection will allow you to save more money with solar panels through better efficiency rates, net metering, plus lower equipment and installation costs:
- Batteries, and other stand-alone equipment, are required for a fully functional off-grid solar system and add to costs as well as maintenance. Grid-tied solar systems are therefore generally cheaper and simpler to install.
- Your solar panels will often generate more electricity than what you are capable of consuming. With net metering, homeowners can put this excess electricity onto the utility grid instead of storing it themselves with batteries.
- Net metering (or feed-in tariff schemes in some countries) play an important role in how solar power is incentivized. Without it, residential solar systems would be much less feasible from a financial point of view.
- Many utility companies are committed to buying electricity from homeowners at the same rate as they sell it themselves.
2. The utility grid is a virtual battery
- Electricity has to be spent in real time. However, it can be temporarily stored as other forms of energy (e.g. chemical energy in batteries). Energy storage typically comes with significant losses.
- The electric power grid is in many ways also a battery, without the need for maintenance or replacements, and with much better efficiency rates. In other words, more electricity (and more money) goes to waste with conventional battery systems.
