Grid-tied, on-grid, utility-interactive, and grid back feeding are all terms used to describe the same concept, a solar system that is connected to the utility power grid. These systems are connected to the utility grid and do not require battery storage. Excess solar power that you generate from an on-grid is exported onto the utility grid and you get paid a feed-in-tariff for the energy that you export. Grid-tied solar systems unable to function or generate electricity during a blackout or power outage due to safety reasons.
Integrated solutions for centralized PV power plants with customized roof-top planning and implementation flexibility from MNM. You can expect highest safety factors and availability, and greatest long-term yields throughout the entire service life which ensures the project's success and a maximum return on your investment.
1) Grid-tied PV systems are more efficient and cost lesser their off-grid and hybrid counterparts because these systems don’t require batteries and other stand-alone equipment. A PV system on your roof will massively reduce your power bills (sometimes even nullify!) because you will generate your own electricity. The excess electricity produced in your grid-tied PV system is injected into the grid. The utility companies will pay you for this excess energy with a feed-in tariff. The electric tariff is expected to rise even more in the coming years. With a 25-year performance warranty, this insightful investment will give you long-term benefits and another source of income.
2) Electricity needs to be spent in real-time. None the less, it can also be temporarily stored by conversion into forms of energy. For example, Lead-acid batteries, which are commonly used with solar panels, are only 85% to 90% efficient at storing electric energy, and this performance also degrades with time. Additional benefits of being grid-tied include access to backup power from the utility grid (in the event that your solar system stop generating electricity for reasons like weather or time of day). Concurrently, you lend a hand in mitigating the utility company`s peak load, resulting in an increased efficiency of our electrical system. The utility grid can be considered as a virtual battery. The net meter installed with your PV system will record the amount of excess electricity it has fed into the grid during the day. You can use this excess electricity at night for absolutely no charge!
1) Grid-tied inverter: The job of a solar inverter is to regulate the voltage and current received from your solar arrays and then convert it from Direct Current (DC) into Alternating Current (AC). These inverters synchronize the phase and frequency of the current to fit that of the utility grid (3-phase, 50 Hz). Additionally, the output voltage is adjusted slightly higher than grid voltage so that excess electricity flows into the grid.
2) Net meter: You will need to replace your current power meter with a net meter. This device is capable of measuring power going in both directions, from the house to the grid and vice versa.
