Solar Panels

What are solar panels?

Solar panels also are known as Photovoltaic solar panels, solar modules, solar plates or सौर ऊर्जा are made of silicon cells which convert sunlight into electricity. Thus generating clean energy free of cost for a period of 25 years. Solar panels available in the market are classified into two types: polycrystalline and monocrystalline solar panel. Solar panel price ranges from ₹25 to ₹35 per watt depending on the size of the solar power system. For example, a 1kw solar system would have 1000 watt of solar panel installed beside batteries and inverters. Another important factor that determines the price of a solar panel is the size of the solar system. Solar panel prices are measured in per watt price, the price of solar panels will go down if you buy in bulk and it depends upon efficiency of solar panel and warranty offered on it.

How do solar panel work?



In 1839, Alexandre Edmond Becquerel discovered the photovoltaic effect. Photo means "light" and voltaic means "electricity" in Latin, photovoltaic means "electricity from light". When discovered, solar panels were used to merely measure light. Solar panels became effective after the invention of the transistor. The solar panel is made of semiconductors like siliconWhen sunlight falls, electrons in the solar panel start flowing towards positive and negative terminals and generate electricity.

        • Solar panels have a Long-term lifespan
        • Solar panels produce free electricity from day one
        • Environment-friendly green energy production
        • Solar panels are flexible, customizable and portable

        Disadvantages of solar panels 

        • Solar panels are dependent on sunlight
        • Solar panels require a specific area for installation
        • Solar panels have maintenance costs

          Maintenance of Solar Panels

          Solar panels are low maintenance products, however, it is important to clean solar panels on a regular basis to clear off the dust particles that gets accumulated on the solar panels. 

          Things to Remember While Cleaning Solar Panels

          • No specific cleaning liquid required, Normal garden hose can be used to spray water on solar panels.
          • Never use hot or cold water as there are chances that solar panels might get damaged. Instead of sprinkling water using hose, you can also pour water gently over the solar panels. Use soft clothes to wipe off the excess water. Automatic sprinklers can also be fitted near to solar panels which will take care of the cleaning job.


            Avoid Common Mistakes People Make When Installing Solar

             Top mistakes people make when installing solar


            Solar panels effectively produce electricity for a period of 25 years from the day of installation. However, solar panels should be installed properly to churn out the benefits in the long run.


            There are 5 major common mistakes generally Solar Installers happen.


              1. Solar panel mounting structure should be made of GIA. The normal iron stand will not have a longer life as they are not rust-proof. So, we recommend to use GIA Stand for solar panel installation.
              2. Proper Fixing of Solar Panels is important. Solar panels laid and fixed on mounting structure so that it doesn’t tilt or sway. Solar panel mounting structure should be grounded with civil work; general civil work involves 4*4 inch foundation work. Fasteners, preferably top brand like Anchor should be used for structure fastening.
              3. Wiring of solar panel with MC4 Connector. MC4 connectors should be used for connecting solar panels, instead of connecting solar panels with tapes. MC4 connectors can be joined together manually, however, they will not unjoin unless a tool is applied, hence it ensures circuit does not breakup.
              4. 30Degree Installation of solar panels. Solar panels should be installed always at 30 degree angle to extract maximum efficiency. Angle of installation results in maximum power generation. Also, solar panels should be installing facing south-west direction.
              5. 3 Earthing stands for solar systems. Earthing protects your solar system, protects against overload, directs excess electricity to ground, voltage is stabilised and prevents mishaps

              Solar Panels - FAQs

              Q. How Many Solar Panels Do I Need To Power My Home?


              Ans. Today people are going solar not only to reduce their carbon footprint, but also to save big on their electricity bills. If you decided to go solar one of the simple questions that pops up in your mind is how many solar panels do I need for my home?


              Yes, this is one of the most common queries that we receive from our readers - how many solar panels should I install on my rooftop? While this is a valid question, a lot of factors go into account to arrive at an answer.


              The number of solar panels that one requires for his house or shop or any other commercial application primarily depends upon:


              • The location of your establishment and the weather conditions
              • The amount of electricity that is consumed
              • The surface area of the roof and
              • The brand and efficiency of the panels that you use


              The first point is very important while considering a solar system. If you are located in central India where solar irradiance is higher you will require lesser number of panels when compared to a location in north India, After you have worked out your location and brand of the panels, you need to find out the number of panels that would be required to power your daily energy requirement.


              To know your establishment’s average energy requirement you need to have a look at your past electricity bills.


              Number of solar panels can be obtained by multiplying your hourly energy requirement by the peak sunlight hours and then dividing this number by the panel’s wattage.


              You can determine the number of peak sunlight hours of different Indian cities from the MNRE website. It is 5 hours in average in India. Delhi typically receives between 5.5 - 6 hours of peak sunlight.


              You can calculate the amount of energy that a panel will per hour by multiplying your hourly energy requirement by 1000 and dividing this number by peak sunlight hours.


              Alternatively, if you have decided not to go completely off the grid, you may calculate your daily energy requirement by multiplying the wattage of each appliance with the number of hours it runs daily and adding them all. It is better to multiply this number by 1.5 to account for all types of transmission and efficiency losses. This will give you the total amount of energy needed from the solar panels. Divide this number by peak sunlight hours to get the wattage of the panels.


              Q. How to Determine the Wattage of the Solar Panel to Be Used?


              Ans. Another question that comes to a buyer’s mind is what wattage solar panels should I use?

              If you receive 4 hours of peak sunlight and you are using a 250-watt panel, you will able to generate 30 kWh in a month (4x250x30) or 1 kWh a day.


              How does efficiency of a panel play a role in determining the number of panels to be used?


              Always remember, the efficiency of a panel is inversely proportional to its number. That means, the higher the efficiency of a panel the lesser number of panels you will require.



              Q. How do Solar Panels Work?

              Sun light that falls on solar panels is converted to electricity. This electricity from the solar panel is in direct current form and since we use the alternate current to run appliances in our home, an inverter is installed to convert this direct current to alternate current.

              Q. Does Solar Panel Work During Monsoon?

              Solar panels will produce comparatively less energy during monsoon. More sunlight better your solar panel works. Shades, clouds, and monsoon does affect the performance of solar panels. Amount of electricity is directly related to the amount of sunlight that falls on solar panels.
