100kW solar systems are a powerful choice for businesses of all sizes in India. This system size is also being adopted by Resident Welfare Associations (RWA)/ Group Housing Societies (GHS) at subsidized  100kW solar plant costs. Switching to solar provides a perfect solution to reducing your overhead cost and becoming energy independent.

The Working of a 100kW Solar System and Its Benefits

A solar photovoltaic panel is the composition of several silicon solar cells. When exposed to sunlight, the photons interact with silicon and change their electrical characteristics. In simple words, sunlight incident upon the panels sets free the electrons in the cells, generating a flow of direct current. This power passes through the solar inverter and gets transformed into usable AC electricity. 

It takes a strategic arrangement of multiple solar panels for your 100kW solar system to produce enough power to run your property.

The upfront cost of a 100kW solar plant ranges between Rs.30 lakhs and Rs 55 lakhs. The final cost depends on the quality of components and the type of system you pick for your commercial or residential application. However, the benefits of switching to solar are immense and outweigh the initial solar investment by great margins.

Eliminate Electricity Costs

Businesses today have to contend with high overhead costs. Plus, electricity prices have doubled over the last decade making you pay a high utility cost every month. A 100kW solar system on the site can generate zero-cost electricity to meet your day-to-day power needs. As you cut down on your grid withdrawals, you immediately see a reduction in your monthly utility expenditures. Over time, these savings eclipse your 100kW solar system cost in just 6-8 years.

Improved Public Image with Green Credentials

Embracing solar PV technology is a great PR move. Solar photovoltaic technology is capable of making a significant global reduction of greenhouse gases in the atmosphere. Businesses have the opportunity to boost their public image by investing in solar and positioning themselves as an environmentally aware, socially-responsible, and progressive company.

Control of Future Electric Bills

The 100kW solar system prices can be seen as an investment toward hedging your business against future electricity price inflation. Thanks to its ability to generate free-of-cost power, you can lock in a much lower monthly electricity price and eliminate the element of unpredictability associated with grid-supplied power. As a result, it becomes easier for your business to budget and plan for business growth and the future.

100 Kilowatt Solar Panel Price List & Specifications

The commercial and residential 100kW solar power plant costs in India vary vastly. If you want to get the best returns, savings, and conveniences out of your solar investment, it makes sense to choose the best. Here’s an illustration of what you can expect when switching to solar.

Key specifications of a 100kW solar system:

Different Types of 100kW Solar Panel Systems

The key to maximizing your solar potential and savings is to choose a suitable system size based on your location, space, and energy needs. All these factors determine the type of 100kW solar system you should pick and the number of components making up your system. Here is what you need to know about the different types of solar systems to make a confident choice.

• On-grid 100kW solar system (regulated under the net metering mechanism)
• Off-grid 100kW solar system (suitable for remote locations)
• Hybrid 100kW solar system (connects to the grid and also includes solar batteries)

100kW On-grid Solar System Specifications

An on-grid framework is one where your 100kW solar system is connected to the utility company’s power grid in your region. Aside from the main solar components (solar panels and a solar inverter), the system is equipped with a net metering system to record the flow of power between the grid and your solar system. Due to fewer components, an on-grid 100kW solar system cost in India is the lowest among all the three types of solar systems.

During peak sun hours on sunny days, your solar panels are likely to generate a surplus. All the unused solar energy is fed to the grid in return for solar credits. In addition to this, you can fall back on the grid when your solar energy output is insufficient to meet your power requirements on any day. 

100kW Off-grid Solar System Specifications

An off-grid framework functions independently of the grid. Meaning instead of using grid power to meet your additional energy requirements, you sustain on an on-site energy reserve. Solar batteries are an integral component in the composition of a 100kW off-grid solar system that eliminates grid dependence as well as the monthly utility bills.

All the solar energy that is not used to run your home or business is stored in the batteries. Your property draws power from this reserve during night hours and on days when solar energy output is inadequate.

An off-grid framework is highly recommended if you own a property in a remote location. Also, it’s a suitable option if you have to pay high electricity prices because the utility grid is located far away from your region or if you’re troubled with prolonged outages.

100kW Hybrid Solar System Specifications

A hybrid framework can help you unlock your location’s maximum solar potential and the numerous advantages that come with a 100kW solar system. In this type of solar system, you have the functionalities of both net metering and solar batteries. As a result, expect to pay a higher 100kW solar system price upfront.

However, the cost is easily recovered through the financial gains of solar. Not only do you save on your monthly electricity costs but also have solar batteries to keep you powered during outages and night hours.

To meet additional energy requirements, beyond what your solar batteries and solar panels provide, you can rely on the grid. Also, your 100kW solar system stays connected to the grid and gets billed as per the net metering guidelines.
