    Several solar companies provide Operations & Maintenance (O&M) service for the initial 5 years as the major components like solar panels and solar inverters provide warranty for this period. Some solar companies give regular monthly cleaning in a package during the time of installation either for a period of 5 years and even after that. There are also some companies dedicated to the O&M services at a cost. However, there are also several non-professional companies that have flourished. Some of them are seen using high pressure water and detergents to clean the solar panels. So please choose your O&M partner based on their team strength and background.

    In India, March to May generally delivers the highest solar power generation, with April often emerging as the peak month for many regions. This is because these months combine very high solar irradiance, clear skies and longer sunshine hours before the arrival of the monsoon season. Northern, western and central Indian states such as Rajasthan, Gujarat, Maharashtra and Madhya Pradesh especially witness strong solar output during this period. However, in some extremely hot regions, excessive panel temperatures during peak summer can slightly reduce efficiency despite abundant sunlight. Solar generation usually drops during June to September due to cloud cover and rainfall during the monsoon season.

    Generally, rooftop solar offers an ROI of over at least 20% in most markets today. Hence, it gives a payback period of about 4-5 years. Even without any subsidy or incentives, chances are, it will pay back your investment in 7 years or less with good maintenance and a net metering regime.

What is the relation between TOPCOn modules and watt-peak (Wp)?

    Deputy Editor at Saur Energy International | Answer on April 9, 2025 at 6:12 pm

    TOCOn based solar modules come in high Wp. Like above 620 Wp. That means that the similar single panel can produce more energy that the conventional soalr panels. This will allow lesser requirement of land for solar projects.

    Yes. You can clean solar panels without water too. For this, you can use soft micro-fibre-based cleaners. These are easily available offline and online. Many of them also come with extendable rod lengths to increase the extent of these dry cleaning equipment.

    A cosumer cannot sell his/her electricity generated from his residential rooftop solar to any party other than the local electricity distribution company. Under the net-metering arrangement under the PM Surya Ghar the surplus energy is taken your power company and they also compensate it accordingly. However, in commercial projects, solar project developers earn money from solar projects. But usually to make money and profits from solar plants, you need to invest more and go through other formalities
