5 things to consider before getting a rooftop solar system for your home

As someone rightly said that if there was some kind of an infinite source of power that was free to use all day, it’ sun. The sun shines all throughout the day in many parts of the world. Who knew that its rays were so valuable that they could generate electricity? Yet today, solar energy has become a renewable source of energy for many countries including India. It has shown its strength to satisfy the power needs for both commercial and domestic purposes.

It’s not just the big industries, many households have either gone solar or are looking forward to. The perks which the Solar Panel offers in the form of one-time investment are so fascinating, that people are getting tempted to get a rooftop solar system for their homes. Just like purchasing any costly electronic appliance requires to do a proper homework, where one analyses his needs and budget, the same goes for a solar panel too. In spite of numerous long-term benefits, the fact remains that installing a solar panel is a costly affair. In fact, it is one of the major reason that halts people from going solar. Thus, it becomes essential to consider certain things before getting a rooftop solar system for your house. In this blog, we will discuss all the aspects in detail.

1. Roof Condition: It might appear unimportant, but the condition of your roof is one of the most important factors to consider when installing a solar panel. As mentioned earlier that it’s a costly job to get a solar panel installed. Thus, any repair work to be done on your roof would require its uninstallation and re-installation, or else it would get damaged. This process would ultimately cost heavy on your pocket. To avoid such situation, it is essential to ensure that your roof is in a good condition to survive as long as fifteen-twenty years as most solar panels also last for the same time period.

2. Power output and efficiency rating : Power output and efficiency rating play a critical role in the performance of a solar panel. In simple terms, they determine how much electricity a solar panel is capable to generate. While most people tend to consider both as one of the same things, in reality, they are quite different. Deciding between the power output and the efficiency rating is directly proportional to your roof size. Suppose, if someone says that he has a 255 Watt solar panel or a 300 Watt solar panel. He is talking about the watt capacity and its power output. It also means that the former is smaller in size and latter bigger. On contrary, a small solar panel with higher efficiency rating can give more output over a bigger one. For example, you have a solar panel of size 65 inches by 39 inches with 20 per cent efficiency rating and another of size 77 inches by 39 inches with 15 per cent efficiency rating. Though small in size, the former will give more output and generate more electricity over the latter.

But, with efficiency comes the cost. More the efficiency rating, more costly is the solar panel. Ideally, people with small roofs should focus on efficiency rating, while those with a large roof can focus on watt irrespective of the size.

3. Shadow casting object : It isn’t necessary to mention that how important sunlight is for a solar panel. Although, solar panels also work on the atmospheric heat, yet the sunlight is on what its entire functioning premised on. Thus, to get the maximum output, it is essential to ensure that there are no shadow casting objects such as trees, pillars and poles near the panel. The same goes for your terrace, where keeping a bunch of things could again caste shadow on the panel. These things can be more properly analysed by an expert and accordingly he can guide with the appropriate point for installation.

4. Background of the company and installer : Most solar panels available in the market are usually designed in a manner that they come with the warranty of not less than 15 years and can typically last for more than 25 years. This is one of the reason that they are so expensive. Basically, it’s a one-time investment for the years to come. Thus, it is essential to thoroughly check the background of the company and ensure that what they claim is what they actually deliver. Check their reviews online or even from your acquaintances who have the same company’s solar panel.

The installer is as equally important as the company. An expert installer would know all the technicalities associated with the installation of a solar panel. Thus, it is advisable to get your panel installed with the company’s professional installer, instead of hiring a local person.

5. Inverter warranty : Your Solar Panel’s inverter is the only component that is likely to fail earlier. While most inverters come with a warranty of a minimum of 5 years, some inverters also come with a warranty as long as 10 years. Thus, along with the Solar Panel, it is also important to pay attention to the quality of inverter which the company is providing along with the panel.
