    Currently, in India, two types of modules are used in solar projects: DCR (Domestic Content Requirement) modules and non-DCR modules. As per government mandates, most government-backed projects are required to use DCR modules. DCR modules are those manufactured using solar cells produced domesticallRead more

    Currently, in India, two types of modules are used in solar projects: DCR (Domestic Content Requirement) modules and non-DCR modules. As per government mandates, most government-backed projects are required to use DCR modules.

    DCR modules are those manufactured using solar cells produced domestically. This means that any solar module made using solar cells manufactured within India qualifies as a DCR module.

    Solar panels usually produce their peak power between 11 AM and 2 PM, when sunlight intensity is highest and the sun is closest to being directly overhead. However, the exact peak generation time depends on factors such as geographic location, season, panel tilt angle, weather conditions and shadingRead more

    Solar panels usually produce their peak power between 11 AM and 2 PM, when sunlight intensity is highest and the sun is closest to being directly overhead. However, the exact peak generation time depends on factors such as geographic location, season, panel tilt angle, weather conditions and shading. In India, especially during summer, many rooftop and utility-scale solar plants see maximum output around noon to early afternoon. That said, extremely high temperatures during peak afternoon hours can slightly reduce panel efficiency, even if sunlight remains very strong.

    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.

    No, you should not sit on solar panels. While panels are rated to be able to carry a certain amount of weight, they are not made for carrying the sitting weight of an adult human. the occasional monkey, birds and hit by hailstones are what panels are designed to weather.

    Yes, hybrid rooftop solar systems are generally more expensive than normal GTI (Grid-Tied Inverter) based systems because they are designed to do more than just feed solar power into the grid. A standard GTI system mainly converts solar DC power into AC and synchronises it with the grid, making it relatively simple and cheaper. In contrast, a hybrid system can manage solar generation, battery storage, grid supply and backup loads simultaneously. This requires a more advanced inverter, additional battery bank, battery management system (BMS), protection equipment and often smarter energy management software. Batteries themselves are a major cost component, especially lithium-ion batteries, which significantly increase the project cost. Hybrid systems also involve more complex installation and wiring. However, they provide backup during power cuts, better energy independence and the ability to store excess solar power for evening use, which a normal GTI system cannot do.

    Team of Solar Faqs | Answer on May 28, 2024 at 11:09 am

    Monocrystalline panels (Mono-PERC) are the best for home use. However, advanced technologies like TOPCon has come emerged as the new choice which offers higher efficiencies but there are selected companies offering this in India.

    While cleaning solar modules with water first thing you should do is to use soft bristle cleaner or dedicated solar panel cleaning brushes. You need to also ensure that you do not use excessive water pressure. Excess water pressure can damage your solar panels leading to the development of microcracks. The maximum pressure that can be used for solar panel cleaning is 35 bars. You should also try to use soft water for cleaning solar modules.

    Extreme heat has a mixed impact on solar power generation. While solar panels require sunlight to produce electricity, excessively high temperatures actually reduce their efficiency. Most photovoltaic (PV) modules perform optimally at around 25°C, and for every degree above this level, power output typically declines by 0.3% to 0.5% depending on the technology used. During intense summer conditions, panel surfaces can heat up beyond 60–70°C, leading to voltage losses and reduced generation efficiency. Heatwaves can also stress inverters, transformers and grid infrastructure, while increasing dust accumulation and water requirements for panel cleaning. However, despite lower efficiency per panel, overall solar generation may still remain high during summer because of longer daylight hours and stronger solar irradiance.
