Beginner’s Guide to Install Solar Panel System at Home

Beginner’s Guide to Install Solar Panel System at Home

The arrival of the summer season is a great opportunity to install a solar panel system at home. However, switching to a solar panel system according to the home’s energy requirements is not an easy task. But, considering its long term-benefits related to savings and Eco-friendly aspects, UTL Solar highly recommends you to get a solar system for your home.

The right way to begin the process would be to start with figuring out the right solar panel system for your house. This decision should be made by calculating several important factors such as your energy needs, the location of your house, your budget, and more. This blog will help you in figuring out these factors. Let’s take a look:

Location of Your House

The location of your property is one of the most important factors to take into account while getting a solar panel system. That is because the performance of any solar panel is directly proportional to the amount of solar radiation they receive. For the most efficient performance, solar panels should be placed in areas with broad sunlight coverage. In case, your house is situated in an area that doesn’t receive ample sunlight then the solar panels have to be more efficient.

Solar Panel Efficiency

Solar panel efficiency is yet another crucial factor that should be considered before installing a solar panel system. It is defined as the ability of a solar panel to convert input energy to output energy. There are many benefits of having a more efficient solar panel such as it supports the solar batteries to charge faster attributing to its higher output. Also, a more efficient solar panel also generates more power in areas that don’t receive adequate sunlight. If you want a panel with average efficiency, then go for solar panels having 15 to 16 percent. 17 to 19 percent is considered to be a better efficiency and a 20 percent efficient solar panel is considered to be the best.

Panel Size

The size of the solar panel that’s right for your home depends upon your energy requirements. To calculate your power requirement, you need to add up the power consumed by each electrical appliance that you are utilizing in your home. Consider your power requirement is as mentioned in the table given below:

EquipmentPower Rating (Watt)QuantityLoadDuty Cycle (Hrs)Daily Energy Consumption (Watt Hours)
LED Light10330260
Total Load (Watts)490Total Daily Energy Consumption (Watt Hours)980

The formula for calculating your panel size requirement 

Panel Size Requirement = Daily Energy Consumption (Watt Hours)/3 

                                        = 980/3

                                        = 326.7 W

This means you can choose to go with 

3 x 100Wp or 2 x 150Wp solar panels in parallel


If you don’t want to keep replacing your panels after a few years, then go for a durable panel that can adhere to extreme weather conditions such as hail, strong winds, rains, etc. A good solar panel would last anywhere between 25 to 30 years. However, this doesn’t mean panels with less life expectancy would cease to perform after the given period. It just means that the efficiency of the panels would start to decrease after that time period. If you are looking for a durable solar panel go for a reputable and old brand such as UTL Solar that has a wide range of solar products such as solar batteries, solar inverters, solar PCU etc. for its customers.

When it comes to buying solar panels, UTL Solar is a preferred brand trusted by all. You can go check out their wide range of offerings online. You can also contact their experts and choose a solar panel system that is perfect for your needs.


How to Choose the Right Time to Install a Solar System?

How to Choose the Right Time to Install a Solar System?

As a company that deals in solar solutions and products, UTL Solar always comes across a prevalent question from readers and potential buyers. Yes, you guessed it right! “What is the right time/season to install a solar system on one’s premises? Most of the time it is observed that buyers are doubtful about installing a solar system during winters or in the rainy season. 

The one thing that everyone should remember is that sunlight on our planet is not a seasonal phenomenon. We are also lucky to be living in the part of the world which receives sunlight throughout the year. So, this answers the question! The most appropriate time to install a solar system is when the sun is shining bright in the sky!However, there are a few misconceptions that flutter around regarding the installation of the solar system. This blog will help you get over those misconceptions and try to answer all those questions which have been in a buyer’s mind before thinking of installing a solar system in their home, office, etc.

Non-Seasonal Product

As explained above, one of the most popular questions is whether solar is a seasonal product? Now, the question arises, what is a seasonal product? Seasonal products are those products that you only need for a particular season such as cooler, heater, or geyser. However, this is not the case with a solar system. Solar panels are functional for 365 days of 25 years, which you have the warranty for. Sometimes it is functional beyond the warranty period too. 

The sun shines each day and you need to switch on your light or fan every day at least. This will be taken care of by the solar system. So, a solar panel is a non-seasonal product. It is perfectly capable of working throughout the year.

Weather Conditions

The second misbelief that people have is regarding the effects of weather conditions on the functioning of the solar system. It is a fact that the climate of a certain place will have a direct impact on the working of your solar system. However, as we have discussed earlier, it is not like India does not receive sunlight at all. As long as there are sun’s rays falling on the solar panels, your solar system will function. Nowadays, solar panels can work efficiently even in low-light conditions. According to UTL Solar’s experts, solar panels generate 10% to 25% power generation in rainy seasons.

Consumption vs Production

Some of the critics argue that the output of a solar system is less in winters as the sun is not very strong at that time. Yes, this is true, there will be some difference. However, other factors should be taken into account such as your consumption pattern. During winters the consumption rate is also low. When your consumption of power is high such as in summers, the production of power from solar panels is also high. It is also seen that air conditioners utilize a large amount of power. It is recommended that customers should install DC appliances as they consume low power to run. 

So, before making up your mind you should calculate your consumption and then decide on choosing the right solar system.

Real Use Case Scenario

Installing a solar system in small towns is completely lucrative. Since villages and small towns face more power cuts, they need to become independent of the grid. Though it is claimed that electricity has reached the remotest parts of the country, the actual scenario is a bit different and regular power cuts are observed during natural adversities such as heavy rains or floods, unlike in big cities. 

It was seen during the recent floods in parts of the country like West Bengal, Bihar, Jharkhand, Assam, Rajasthan, and more were still struggling for power. If consumers had a solar system in place they would have power irrespective of the main power supply.

Use of Latest Technology Product

Sometimes consumers are unable to install a solar system at the right time as they do not get the required and appropriate technical advice. Lack of technically sound sales consultants and lack of proper technical product details sometimes dissuade buyers from investing. 

Consumers do not get much-required knowledge and are unable to buy the latest technology product. They prefer to buy goods based on low prices, and the majority of the sellers are ready to sell them low-quality products because they do not want to lose the customer. If a customer has the proper knowledge about technically advanced products, they will surely buy them even for a little higher price tag. Below mentioned are some of the latest technology solar products:

  • Panels – Monocrystalline
  • Wire – DC cable
  • Inverter – rMPPT (UTL Solar’s Technology),
  • Panel Stand – Wall Mounted, etc.

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 solar 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 solar 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.


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.

5 Reasons, Why You Need a New Inverter

In today’s world inverters have become more of a necessity than a luxury. Almost every household work requires an electrical appliance and the usage of electricity. Therefore, inverters are a must-have commodity in every household. There are more factors that back up this statement such as increased load shedding and power outages can disrupt your work schedule and personal comfort, especially during summers.

Getting an efficient and effective power backup system is one of the easy ways to get rid of these problems. People who are used to air conditioners can face a lot of trouble during summers. And sitting in a room with no fan? Can become torture. UTL Solar advises getting an efficient inverter for power backup if your residential area experiences regular power cuts. This will help in making sure you have proper backup energy for emergency needs. Remember, if you plan to upgrade your inverter, purchase one that supports the load requirements of your house for efficient use of the power backup that an inverter provides. Before buying a new inverter, It is important to make sure that your current inverter works efficiently. Inverters and batteries are prone to lack in performance due to extended use over the years and show a hampered functioning.

So, if your inverter is not functioning like it used to, or has a persistent problem, you should upgrade your inverter that has better and smarter technology. Check out these Here are five reasons you should upgrade your inverter:

1. Inverter is not Charging the Battery Completely

One of the most common problems that people face with their inverter is the inverter battery stops charging. Generally, in these cases, the problem is of a dead battery or there is a fault with the grade separators. You can either buy a new battery or get it replaced if it is in the warranty period. However, this problem can arise due to other inverter related issues. These problems include burnt rectifiers, rusted terminals, fused active material, or even an electrical fault in the main board. Depending on the issue and after talking to a technician, you can decide to get a new battery or upgrade your inverter.

2. Batteries Need Maintenance

If your inverter is facing an electrical board failure or repetitive beeping of the alarm, or the monitor displaying incorrect codes, you should contact a professional technician. These issues can occur due to problems with battery wires and cables, or it might be that your inverter keeps switching from the mainline grid to the battery. Based on the maintenance observations, you can choose to upgrade your inverter to avoid spending unnecessary money on constant maintenance. In case you want to buy a new battery, you should go with tubular batteries or gel batteries to enjoy consistent backup power and longer battery life.

3. Increment in Load Needs

With the passage of time, it is inevitable to buy new appliances, devices, and other electronics. This will increase electrical load requirements, which your present inverter and battery might not be able to support. Inverters and batteries are engineered with a certain capacity, which should not be exceeded as it can burn out the inverter system or result in a power failure. This can also lead to the degradation of the life of the appliances and electronics used. Understanding your load requirements is critically essential to find the most effective power backup solutions. Here, you must remember these two things – Power Requirement and Volt Ampere (VA) Rating.

4. Customer Support Is Not Satisfactory

We live in a world of quick deliveries and 24/7 customer service. Amidst all this, if you don’t get a technician on time to repair or maintain your inverter system, it can be an unpleasant experience. If your present power solutions brand does not provide you with the required customer care support, you should upgrade your inverter from other reputed brands that provide at-home maintenance checks, and quick solutions to your problem.

5 Useful Tips for Efficient Working of Your Inverter Battery

5 Useful Tips for Efficient Working of Your Inverter Battery

We all know a battery is the powerhouse and backbone of an inverter. The battery is responsible for the efficiency and extended life of your inverter system. Routine maintenance and servicing of the battery not only fosters optimal performance of your power backup system but also ensures safety of the place where the system is set up. Similar to any other device, your inverter and its battery requires periodic maintenance. Regular checkups of the battery is a necessary job in order to ensure uninterrupted performance. Battery should be checked every two months to make sure condition of the battery is okay. UTL Solar has a wide range of inverter batteries that need less maintenance as compared to other brands in the market. Here are some tips that would help you keeping your battery in excellent condition:

1. Keep the Battery in a Well Ventilated Place:

Always use a well-ventilated area for inverter installation. Generally, the inverter battery gets warm and heated up during charging and operation. A ventilated space allows the battery to cool down easily and reduces the heating. Moreover, it also reduces the frequent water topping requirement.

2. Check the Acid Level Regularly

Check the water level of the battery every two months with the help of float indicators. Water level should be maintained between the maximum and minimum limit. Always top up the battery with distilled water. Do not use tap water or rain water as it contains excess minerals and impurities which hamper the life and performance of the battery. Ensure batteries are not overfilled. Filling up the battery beyond the set limit might be dangerous for operation.

3. Keep the Surface, Sides, and Terminal Area of the Battery Clean

You should always keep the surface and sides of the battery clean and dust free. Use cotton cloth to clean these surfaces. During normal operation, the inverter battery generates lead sulphate, which gets deposited at the terminal region of the battery & inverter. This increases the electrical resistance of the current-conducting path and hampers current flow from the inverter to the converter. Therefore, these terminals should be cleaned with warm water and a nylon brush if there is any sort of accumulation.

4. Check for Damaged Wires

Test the battery wires for any crimp, break, and insulation melt. Tampered or Damaged battery wires not only decrease battery output but can boost the risk of short circuits and other mishaps.

5. Check the Inverter’s Input Power Line

Check the condition of the input power line to the inverter as it can hamper the functioning of the inverter system if the mainline power cord is loosely plugged in or if there is no power in the wall socket. Too high or too low input voltage can affect the performance of the battery.


In addition to these things, you should make sure the battery is out of reach from children and is kept in a well-ventilated place with no direct sunlight or heat to ensure safe and proper battery functioning. UTL Solar advises, to comply with these tips for a safe and optimum operation of your inverter battery. You should be careful that the vents around the battery are dust free and open. Blocked vents lead to hydrogen gas accumulation ,which may be hazardous. UTL Solar is dedicated to designing and manufacturing products that require minimum maintenance.

5 Points to Select The Right Inverter Battery

We all know that choosing an inverter is relatively easy as compared to the battery. Since inverters are advertised sufficiently, the buyer gets a rough idea about their working performance in various workloads and environments. However, selecting the right inverter battery , which is the heart of the inverter system, is of utmost importance.

People generally pick the battery hoping every single one is the same. But this is not the case, though the ultimate function of the battery is to hold the charge, yet there are quite a lot of differences between the ones that are reliable versus the ones that are a bit more affordable.

Generally, a battery that costs more also offers better performance and comes with a longer service life as compared to other batteries that are cheap and are rated for the same capacity. So, how do you know which ones to pick? Well, we are providing you with the required guide to select a decent battery that won’t become a burden on your pocket and will serve you well in the long run. So, without further ado, let’s check out the points.

Tips to select an efficient battery:

1. Tubular vs. Flat Plate:

Flat plate batteries are ideal for limited space because of their small form factor. They will easily fit in almost any space; however, these batteries tend to have a shorter service life as compared to Tubular batteries because of their inherent construction. On the other hand, Tubular batteries have a considerably longer service life. However, at the same time, it requires more recharge time after a long power cut compared to a flat plate battery. This is why tubular batteries are considered to be ideal for long power-cut situations in India and flat plate batteries are best suitable for short & frequent power cut situations. Whatever, flat plate or tubular plate construction, the performance & life of any lead-acid battery depends on two major characteristics – the robustness of the manufacturing process and purity of basic raw materials. UTL Solar takes utmost care of both of these characteristics while manufacturing its batteries.

2. Weight:

It is a fairly elemental way to analyze quality but if possible, it is always suggested to measure the weight of the batteries (excluding the packaging) before purchasing them. Generally, a heavier battery has higher quality electrolyte plates which are considered to provide give them a longer lifespan.

3. Maintenance:

Any battery that you purchase is going to need some amount of maintenance periodically. However, as explained above tubular batteries need less maintenance as compared to flat plate batteries because of their design. The design of tubular batteries allows them to hold a lot of distilled water, which in turn, makes them less prone to drying out quickly.

4. Raw Materials:

Many batteries experience a significant reduction in performance during the last months of their life. However, UTL batteries provide good back-up, as it has a fully balanced chemical material utilization factor in its positive and negative plates. The combination of carbon, barium sulphate, and lignin has been well utilized in the paste of the negative plates of UTL batteries, which helps in maintaining the ability to store charge in the plate during the end months.

5. Wet Cell vs. SLA:

Wet cell batteries are less expensive as compared to Sealed Lead Acid (SLA) batteries but they need a higher amount of maintenance. On the other hand, SLA batteries have a shorter lifespan and need considerably less maintenance. However, SLA batteries cost a lot more. So, even though SLA is more expensive. Therefore, it is evident that SLA batteries offer a better ROI.


Selecting the right battery is a tough job and should be done after analyzing all the necessary factors. Batteries are the powerhouse of an inverter system. Whereas, the Inverter regulates the electric charge from the battery. You can buy online inverter batteries by UTL Solar as they are one of the most trusted brands in India when it comes to power backup and generation. But, always select your battery wisely according to your load requirements.
