On-Grid vs Off-Grid Solar

Solar energy has also become a need. It is the one that helps us and the environment generate clean energy and reduce power usage. In order to use solar energy, we should use solar power systems. The three most common types of solar power systems are as follows:

    1. On-grid Solar Power System
    2. Off-grid Solar Power System
    3. Hybrid Solar Power System

Each of them has distinct applications and component needs. However, it is essential to know the difference between them. After knowing the difference, you will be able to select it based on your energy requirements. The common thing among them is that they take the direct current voltage produced by photovoltaics (solar panels) during daylight hours and convert it to conventional household alternating voltage by using solid-state DC-AC converters (inverters). However, in each configuration, the inverter has a different logic of operation  There are some similarities between them, like energy generation and energy management, but when it comes to cost and savings on electricity bills, they vary. This blog will look into the difference between on-grid vs. off-grid solar.

What Is an On-Grid Solar Power System?

A solar power system that is connected to the electric utility grid is called an on-grid solar power system. It generates solar electricity and sends it to the grid; sometimes the excess power is sent to the power board. Living with an on-grid solar power system is identical to living with grid power, except that some or all of the electricity used comes from the sun. In certain states, homeowners are credited by the utility for any extra solar electricity generated. This credited amount from the government can be used in other months when the system produces less or when electrical consumption is higher. This process is known as net metering or net billing, and the specifics of the laws and regulations for it vary from state to state and utility to utility. To get proper guidance, one can consult their local electricity provider or state regulatory agency.

What Is an Off-Grid Solar Power System?

An Off-Grid Solar Power System is connected to the electrical grid and is equipped with battery support. This type of solar power system finds its primary application in remote and rural areas where continuous power cuts are a common occurrence. The beauty of this Off-Grid Power System lies in its versatility; it can be installed virtually anywhere, providing households with the capability to operate independently from the grid, supplying all their electricity needs. This translates to freedom from electric bills and protection against blackouts, particularly those caused by grid failures.

What Are the Difference Between On-Grid and Off-Grid Solar Systems?

Let’s look into the difference between On-Grid and Off-Grid Solar Power Systems:

FactorsOn-Grid Solar Power SystemOff-Grid Solar Power System
Grid ConnectionConnected to the gridConnected to the grid
Battery StorageDoes not include Battery Storage.Includes battery storage to store excess energy.
Energy IndependenceRelies on the grid for power supply.Operates independently from the grid.
Electricity ExportCan export excess electricity to the grid.Does not export electricity; surplus is stored or wasted.
Blackout ResilienceLoses power during grid outages for safety reasons.Continues to supply power during grid outages.
Usage ScenariosFamiliar in urban areas with reliable grid access.Familiar in remote or rural areas with unreliable grid access.
CostsLower upfront costs due to grid reliance.Higher upfront costs due to battery storage.
Maintenance Typically lower maintenance requirements.Requires regular battery maintenance.
Energy WasteMay waste excess energy when not used.Stores excess energy for later use, minimizing waste.
Grid RegulationsSubject to grid-related regulations and fees.Not subject to grid regulations and fees.
Net MeteringCan benefit from net metering, earning credits for excess electricity.Not eligible for net metering.
Installation LocationMore flexible regarding installation location.Must be carefully planned based on energy needs and sunlight.
Environmental ImpactMay indirectly support fossil fuel-based grid energy.
Tends to have a more direct positive environmental impact.
Energy PlanningLess focus on energy management and storageRequires careful energy planning and management.
