On-Grid Solar System

GOBIND Complete On-Grid Power Solutions

On Grid" or "Grid-connected" systems are the systems that are connected to the utility grid through a special inverter. These Systems are more prevalent in "Feed-in Tariff" Applications. These Systems could be either be Roof Top mounted or Free Field Installations based on the size and capacity.

On grid solar energy is by far the cheapest form when compared to off grid solar energy. By generating your own electricity you reduce your electrical bill and in some cases may generate money by running the meter backwards (net metering). Usually you can achieve net metering during the day when all your appliances are off. This net metering or extra power is sold to the utility company through a program offered that you must sign up for. Also green power is handy during power failures so long as you have sunlight for your on grid solar system. A major benefit of these systems include the ability to be expanded as finances allow, they work against global warming on your own personal level, reduced electrical bills, security with backup systems, and remote availability of electricity.

Off-Grid Solar System

Off grid systems are autonomous systems for the production of electrical energy and are an excellent solution for locations that cannot be connected to the main power grid. By adjusting these systems to your exact needs, GOBIND is bound to satisfy your electric energy demands.

When designing an autonomous (off grid) system, we require our customers to provide the following information: average monthly consumption of electricity, inventory of appliances and their average working time during the day. This information will help us to determine the optimal capacity of the system and provide you with the best possible solution. In the case of refrigerators and freezers daily consumption can be determined approximately, and it is only necessary to state the number of these appliances. Consequently, the information we require from you is necessary in order to optimize the solar system in a household.

Grid Tied Solar System

The "Grid-Tie With Battery Backup" PV system incorporates one or more special AC circuits which are not directly connected to the electric grid like the rest of the building, but are always powered through the inverter and/or charge controller. These circuits may power a refrigerator, selected lights, computers or servers... any devices the owner deems essential. The "dual function" inverter can supply the utility grid with any excess power produced by the system like the "grid-tie" inverter, plus the inverter works with the PV modules and battery bank (through the charge controller) to provide AC power to the backup circuits when the grid is down. The charge controller manages the battery voltage, keeping them fully charged when the grid is live, and preventing them from being depleted when the system is drawing power from them.


Hybrid Solar System

Hybrid solar systems combines the best from grid-tied and off-grid solar systems. These systems can either be described as off-grid solar with utility backup power, or grid-tied solar with extra battery storage.

Advantages of Hybrid Solar Systems

1. Less expensive than off-gird solar systems

Hybrid solar systems are less expensive than off-grid solar systems. You don't really need a backup generator, and the capacity of your battery bank can be downsized. Off-peak electricity from the utility company is cheaper than diesel.

2. Smart solar holds a lot of promise
The introduction of hybrid solar systems has opened up for many interesting innovations. New inverters let homeowners take advantage of changes in the utility electricity rates throughout the day.

Solar panels happen to output the most electrical power at noon – not long before the price of electricity peaks. Your home and electrical vehicle can be programmed to consume power during off-peak hours (or from your solar panels).

Consequently, you can temporarily store whatever excess electricity your solar panels in batteries, and put it on the utility grid when you are paid the most for every kWh.

Smart solar holds a lot of promise. The concept will become increasingly important as we transition towards the smart grid in the coming years.

Equipment for Hybrid Solar Systems
Typical hybrid solar systems are based on the following additional components:
- Charge Controller
- Battery Bank
- DC Disconnect (additional)
- Battery-Based Grid-Tie Inverter
- Power Meter

Battery-Based Grid-Tie Inverter

Hybrid solar systems utilize batter-based grid-tie inverters. These devices combine can draw electrical power to and from battery banks, as well as synchronize with the utility grid.
