Alfa+ Solar PCU

Alfa+ Solar PCU: Ultimate for Industrial Usage

Nowadays, every other business and household is becoming eco-conscious, the need to use renewable energy sources for generating electricity is obvious. And installing solar PCUs and inverters is one the easiest ways to meet your power requirements while being an ecologically conscious citizen. Most hospitals, schools, industries, petrol pumps, banks and homes are able to realize the enormous potential of solar energy. Come let’s understand the difference between solar inverter and solar PCU.

What is a Solar Inverter?

A solar inverter is among the most critical components of any solar energy system. It facilitates the conversion of direct current (DC) into alternating current (AC) to produce electricity for usage in a wide range of domestic, business, and industrial applications. From televisions to refrigerators and even major technical equipment, solar inverters can power them all.

In addition to being environmentally sustainable, they also help track the entire solar system’s efficiency and provide the analytical data needed to detect and repair any technological faults. Users can also use the excess stored energy in batteries with inverters.

In the case of a solar inverter, solar energy charges the battery during the day, and in the absence of sunlight, the main grids charge the battery. During a power cut, the energy stored in the battery will come to your rescue and help you continue your lives smoothly. Now that we’ve got that covered, let’s look at what a solar PCU (Power Conditioning Unit) is.

What is a Solar PCU?

Sounds like the same thing, doesn’t it? Well, not really. While a solar PCU is similar to a solar inverter, there are a few differences. In a solar PCU, solar charging takes priority during the day. The Solar PCU controls the priority and optimally selects the source of charging. It comes with user selectable energy saver mode which allows the user to select the priority and save the bill. It also selects the source of AC output to be either from the Solar or inverter or the grid. In the Energy Saver Mode priority is given to Solar, the battery is charged first and also supports the inverter to power the appliances. Once the solar energy stops, the PCU starts consuming the stored energy from the battery. Once the stored energy is used to a particular level, the inverter switches to grid. The main focus here is to save the electricity bill cost.

In a solar PCU, solar energy takes precedence, and only in the absence of solar energy is power from the mains used. Solar PCUs are designed with the intent to gain maximum benefits from the sun and therefore reduce energy costs.

Benefits of a Alfa Solar PCU:

On-Grid Solar System - A Great Choice for Home Owners

Why On-Grid Solar System is a Great Choice for Home?

For some time, solar energy has become one of the most affordable, dependable, and financially viable sources of energy. Most people are aware of the ‘Eco-friendly’ benefits of solar energy. However, there are other interesting financial rewards associated with solar energy, which are motivating people to replace traditional electricity with solar electricity as well. Solar power/energy requires an initial investment where you’ve to purchase a solar system and install it on your home or business property. However, after the initial investment, The whole scenario becomes a lifetime of savings option with lowered energy bills and increased property value. Here are some points that make the on-grid solar system a great choice for home:

It offers Instant Savings

These days with new and advanced technology growing faster than ever, the question is not if solar electricity saves money, but how much money does it save. Because of solar panels generating utility-free electricity along with government incentives, you’ll observe your bills plummeting down and savings rise up. Whether you have purchased the solar system using cash or a loan, the solar electricity bill will definitely be less as compared to a traditional utility bill. In fact, you may save money instead of spending money on buying energy.

In-Built Savings

Every month you’ll experience small energy bill savings, which will add up quickly over a certain period of time. Depending on whether it is cash or loan purchase, those savings will be observed immediately or add up to something big over time.

Everyone experiences different savings, because of the difference in location, sun exposure, and many other factors that affect the solar energy generated. While some may get 30% savings, there may be lucky ones who make 100% savings.

Long term Savings

When a customer invests in a on-grid system by UTL Solar, their investment will promise them a return every month. Now, the generated energy from the solar panels leads to a possibility that you don’t have to pay the utility company at all. Not only do you accumulate energy, but it will be credited to your account, proper accounting and adjustment will be done in the form of import/export and banking.

This clearly leads to the fact that whatever is generated extra, that will be adjusted in your peak demand, if there are some extra credit units in your account, it will be paid according to the FIT rates of that year.

This ultimately means that apart from savings you may earn something for the extra units your solar system has generated. So, basically, you will be paid for the extra units sold to DISCOM.

Depreciation Benefits

This advantage is given to promote the usage and application of the on-grid system in the industrial/commercial segment. 40% AD (accelerated depreciation) can be claimed for the installation of these systems. This facility ultimately affects the tax payment.

Conclusion

Apart from these benefits, there are some other benefits as well such as low gestation period, decreased transmission and distribution losses, improvement in the tail-end grid voltages and reduction of system congestion. Integration of the solar system leads to long term energy and ecological security because of reduction in carbon emission. It has minimal technical losses as power consumption and generation are collocated.
