Did you ever know that you could get the best solar panel system for your house that too for a price as low as ₹1 lakh? The cost of solar panels is seen to be falling every year. We all want to save on paying electricity bills. Installing the right solar roof panels can do good justice for your house in India. Here is a guide to aid you with everything that you should know.

Solar Panel Price in India

The following is the list of different types of solar panels and an approximated price of the same.

50 W 12 V Monocrystalline solar panel : ₹2000 to ₹2500.

100 W solar panel : ₹3000 to ₹3500.

100 W 12 V Polycrystalline solar panel : ₹3500 to ₹4000.

200 W 12 V Polycrystalline solar panel : ₹7000 to ₹7500.

250 W 24 V Polycrystalline solar panel : ₹8000 to ₹8500.

300 W solar panel : 10,000 – ₹11,000.

Moserbaer 305 W 30 V solar panel : ₹13,000 to 13,500.

Since the demand has increased at great levels in India, the price of home solar panels has become most affordable. Electricity is getting more expensive nowadays. Frequent power cuts are making the audience find out more alternatives to the same. India being a favourable nation since it has a lot of solar energy in its atmosphere, the solar panels are one of the best sources of electricity at home.

Types of Solar Panels

  • Crystalline Silicon

90% of the photovoltaics in the world uses silicon in some or the other variation. More the pure form of silicon is present; better will the solar cell be able to convert sunlight into electricity. Thus, the efficiency of the solar panel is adjacent to the purity. However, the process of enhancing this purity in the silicon is pretty expensive. Therefore, do not make the efficiency a primary concern. This is because the cost and space efficiency are what matters the most. The crystalline silicon forms the basis of monocrystalline and polycrystalline solar cells.

The monocrystalline is also known as the single crystalline solar cells. One can recognise them with its external colour and a uniform look which shows the high purity of silicon. They are made of silicon ingots, thus, in a cylindrical shape. In order to lower down costs and optimise the performance, its four sides are cut out from the ingots to create silicon wafers. This is what differentiates them from others. On the other hand, the polycrystalline solar cells are perfectly rectangular, thus, no round edges.

  • Polycrystalline silicon

They are the oldest forms of solar cells available in the market. Here, the raw silicon is melted and poured into a square-shaped mould. It is cooled and then cut into perfect square biscuits.

Understanding the Basics of Solar Panels

Before actually investing in buying and installing the solar panels at home, it is favourable to have an estimate of how much will you be able to save. The installations initially need funds, but in the long term, it will be a huge save of energy. Major factors that you need to consider while opting for a solar panel installation are as follows.

  • Area of your house

It is not only the location of the house that matters but the area too. The solar panel system can generate energy from both the direct sunlight and scattered light that hits the panel surface. However, if the roof of the house is not exposed to the sun for a reasonable time period in a day, then you might not end up saving much.

How does the size of the house matter?

A big house will obviously need more electricity for its regular use. But will also offer an excellent space for these solar panel installations. Thus, big solar panel systems generate more power providing more kilowatt per hour of electricity. More you spend upfront for a big system installation; more you save in the future compared to a small solar system. One needs to understand that it is not a short but a long-term investment that will bring the right amount of savings after a certain point of time.

  • Low investment risk

Investing in solar panels can get you returns for more than 25 years for sure. Most of the systems have a minimum 25-year warranty. The system also adds up to the value of the property. Thus, if a person does not plan to stay for more than 20 – 25 years, they may consider making a big sum of money when the house is sold off.

How Solar Panels Work?

Since it is a big way to protect the environment, residential as well as commercial places can surely opt for the solar panel installations. The solar panels convert the heat of the sun into electricity that can be used without harming the environment. You end up making your house or commercial property an eco-friendly one.

Every panel consists of several solar cells. The energy produced by the sun is collected and converted into electricity using electric fields. The metal contacts with every solar cell. It plays the best role in May and July during the entire year since these are the hottest months. It has a low effect in the year-end or during the start.

More the number of solar cells present in the panel, higher the output you may expect. Every panel has a different number of solar cells. They are fit as per your consumption requirements. Change in the weather is not in our hand. Any type of obstruction can darken the panels or change its position leading to adverse effects. Thus, one needs to assure they place the solar panel under direct sunlight but far from anything that can become an obstruction.

Once you’ve invested in the panels, electricity becomes free of charge. You make 0% carbon emissions saving the environment.

Solar Panel Installation; Steps You Need To Follow

  • Install in the southern direction

When installing the solar panel, keep the device towards the south position. Generally, when you have pitched or angled roofs not facing to the southern direction, it becomes a problem. However, flat roofs are comparatively flexible in this regard. But it is always suggested to find a space where you can fix the panel facing the south.

  • Assure no shade

Make sure the solar panel when installed is away from any sort of darkness. Tress, for example, may be a major obstruction. Thus, make sure that any sort of shade does not cover the panel at any point of the day.

  • Use metal flashing

The metal flashing will ease the installation since they absorb the required head for a secure installation. You may use 3.8-inch metal bolts made up of stainless steel to fix the panel correctly.

  • Use the solar panel mounts

While installing the domestic solar panel, you may use the solar panel mounts. They are available in three different varieties, i.e., pole mounts flush mounts, and roof-ground mounts. The panel mount assured fixing the device at tough places such as the pole side, slanted roof, etc.

Finally, you are ready to connect the device to the installed panels. If you plan to use solar power only during the power cuts, you may join the solar panel with your home inverter.

Flexible Solar Panels

There is a wide variety of solar panels for home as well as for outdoor use. While some are made using plastic, others are made out of pure silicon. One not only uses solar power system for electricity purpose in the house but may also use them outside. This is possible only with flexible solar panels. You can take them along wherever you go. All you need is the sunlight, to operate them efficiently.

One can instal the portable photovoltaic systems in vehicles and used for primary purposes such as operating the sound system, television, radio, lighting or fan. Depending on the voltage output, we can use these panels for a variety of purposes. People popularly use it to charge their laptops, AA batteries, cameras, smartphones, etc. It is thus a replacement of fuel generators however not emitting any fumes.

Solar Panel Installation IndiaHow To Measure Solar Panel Efficiency

One can measure the effectiveness of the solar panel as a ration of energy from sunlight to the panel that transforms into electricity. Thus efficiency = electricity produced in watts/ solar energy absorbed. Therefore, more the watts the cells produce in the same quantum of sunlight, more will the solar panel be efficient.

Final words

With the emerging need and understanding the importance of solar panels, a huge variety of solar panels are available in the market. You may want to choose as per your budget and further consider your actual requirement. It’s time to save the environment and move to solar energy. It shall be a tremendous individual contribution to the environment.
