Types of Solar Photovoltaic Systems

Solar Electric Systems

At Nu Solar power, we design and supply three kinds of solar energy systems for your property and workplace, depending on your requirements. Each kind has distinct applications and component needs. Here’s all you need to understand.

Grid inter-tied solar electric systems

Additionally, referred to as on-grid, grid-tied, or utility Interactive (UI) systems, grid-tied solar power systems produce solar energy and route it to the electric utility grid. This clean electricity source offsets your electrical consumption. In some times, it may even turn your electric meter backwards!

Grid inter-tied solar system with battery backup

In a grid inter-tied system without a battery or generator backup, it can leave your property and workplace in darkness for the duration of a blackout. With the aid of including batteries for your solar electric system, you could power a few or all of your appliances, like lights, a fridge, a well pump, or computer, even for the duration of utility power outages.

Off-grid solar systems

If you are searching out a dependable way to benefit energy independence from the utility grid, A way to leave the issues of electrical payments and blackouts behind? An off-grid solar electric system allows you to do simply that. Although most common in remote locations without utility grid service, off-grid solar electric systems can work everywhere and cater to all your electricity requirements.

How Does Solar Photovoltaic (PV) System work?

A standard solar photovoltaic (PV) system captures the sun’s energy and converts it into electricity. The solar panels have an arrangement of PV cells that, whilst exposed to daylight, produce power in the shape of Direct current (DC). It surpasses this DC electricity via an inverter, a device that converts the DC power into Alternating current (AC)–the power all of us use for our family lighting and other electrical equipment.

In case you use much less energy than you produce in a grid inter-tied system (shown in Figure 1), it returns extra power to the utility grid. Many states have laws that permit renewable electricity systems to sell extra electricity to the utility, using net-metering.

Here is the image of the role of every component in a grid inter-tied solar power system:

Solar Modules: solar modules installed at the roof or grounds of your house convert sunlight into DC energy.

Inverter: An inverter (Electric Current converter) transforms the DC current from solar modules to AC. This power keeps your home equipment up and running.

Electrical Panel: The current from the inverter travels to your electrical service panel and distributes it to the electrical devices in your property.

Utility meter: When your solar Photovoltaic system generates excessive power, it flows into the grid through a utility meter. This will cause your meter to run backwards, hence gaining you a credit with the utility company.

Utility grid: The utility grid automatically gives power when needed at night time and throughout the day, when your demand exceeds your solar production.

Net Metering: Net metering rules states that the utility company need to credit retail rate to your account, for all the clean electricity you generate and share with the grid. Grid inter-tied Solar Photovoltaic (PV) system with battery backup.

Figure 2 depicts a grid inter-tied solar Photovoltaic system with battery backup. A battery allows you to store the energy produced by using your panels for utilization at a later point in time. At Nu Solar power, we design your battery for a pre-determined ‘number of days’ of storage.
