Power generation from rooftop photovoltaic panels in India

Your location determines the amount of solar insolation (sunlight falling on the panel per day). 1. We generally receive 4-7 KWh of solar insolation per square metre in India 2. The approximate solar insolation at your location can be ascertained by entering the latitude and longitude of your. . In the northern hemisphere a south-facing roof is ideal as the sun is always to the south if you are in the temperate zone and predominantly in the. . Efficiency of the panel is calculated as ratio of capacity of the panel (KWp) with respect to the size (area) of the panel (m2), expressed as a. . Solar panel temperature is an often ignored but critical parameter in a hot country like India. Though it might seem counter-intuitive, solar PV panels generate less power in very hot summers as the heat reduces their efficiency (the voltage reduces). In Chennai, the month of January delivers better output than May . The rated capacity, or power, of a solar panel (e.g. 250 Wp) is measured at 25°C. The effect of temperature on the solar panel’s power is measured by its thermal coefficient, expressed as %/K or %/°C. It denotes the % change in power for 1 degree change in Kelvin or Celsius (both are the same on a unit level) above 25°C. A negative (-) sign. Luckily we can use a simple heuristic for calculating the power output in India: 1 KWp of panel will generate about 1,400-1,600 KWh (units) per year i.e., about 4 KWh per day. This is broadly representative of output from rooftop PV plants in India. It is an average calculated over a year. A contrasting perspective of decentralised power generation analysis is presented for roof top power generation enhancement and solar industry growth in India. As a case …

Featured Solar Products

High - Efficiency Photovoltaic Panels

High - efficiency photovoltaic panel with a sleek design, showing the high - tech surface and sturdy frame.

Our photovoltaic panels are at the forefront of solar technology. With advanced cell designs and high - quality materials, they offer exceptional energy conversion rates, allowing you to maximize your solar energy harvest. Whether installed on a residential rooftop or a large - scale solar farm, these panels are built to last, withstanding harsh weather conditions and providing reliable performance for decades.

Advanced Monocrystalline Solar Panels

Monocrystalline solar panels with a smooth and shiny surface, indicating their high purity and efficiency.

These advanced monocrystalline solar panels are crafted from single-crystal silicon, which endows them with outstanding electrical properties. They have a higher efficiency in converting sunlight into electricity compared to other types of panels. Their sleek appearance also makes them a popular choice for both residential and commercial installations. Moreover, they are durable and can maintain stable performance under various environmental conditions, ensuring a long lifespan and excellent return on investment.

High - Capacity Lithium - Ion Energy Storage Systems

A high-capacity lithium-ion energy storage system with multiple battery modules neatly arranged, showing its modular design.

Our high - capacity lithium - ion energy storage systems play a crucial role in optimizing solar energy usage. Utilizing state-of-the-art lithium-ion battery technology, they can store a significant amount of energy generated by solar panels during the day. This stored energy can then be used during peak demand periods or when sunlight is insufficient, such as at night or on cloudy days. With features like high energy density, fast charging, and long cycle life, these systems provide a reliable and efficient solution for energy storage, enabling you to achieve greater energy independence.

Smart Hybrid Inverters

A smart hybrid inverter with a clear display screen and various connection ports, highlighting its intelligent control and integration capabilities.

Smart hybrid inverters are the key to a seamless and intelligent solar power system. They can intelligently manage the flow of electricity between solar panels, energy storage systems, and the electrical grid. These inverters not only convert the direct current (DC) from solar panels into alternating current (AC) for household or business use but also optimize the charging and discharging of energy storage systems. With built-in monitoring and communication features, you can remotely control and monitor your energy system, making it easy to adjust settings and track performance.

Portable Solar Power Stations

A compact and portable solar power station with a handle and built-in solar panels, suitable for outdoor activities and emergency power supply.

Portable solar power stations are designed for on-the-go power needs. They integrate solar panels, energy storage, and inverter functions into a single, lightweight unit. Ideal for outdoor enthusiasts, campers, and those in need of emergency backup power, these stations can charge various electronic devices like smartphones, laptops, and even small appliances. Their portability and ease of use make them a convenient choice for anyone who wants to access clean energy wherever there's sunlight, providing a reliable power source in remote locations or during power outages.

Distributed Photovoltaic Power Station Solutions

A distributed photovoltaic power station with multiple solar panel arrays spread across different rooftops or open spaces, demonstrating its scalability and wide coverage.

Our distributed photovoltaic power station solutions are tailored for various applications, from small communities to large industrial complexes. By distributing solar panel installations across multiple locations, we can make better use of available space and increase the overall energy generation capacity. These solutions are designed with high-performance components and integrated monitoring systems to ensure efficient operation, easy maintenance, and maximum energy yield. They also contribute to reducing the reliance on the main power grid and have a positive impact on the environment.

Micro Inverters

A small micro inverter with a simple yet functional design, showing its connection points for individual solar panels.

Micro inverters offer a unique advantage in solar power systems. Unlike traditional string inverters, each micro inverter is connected to a single solar panel, allowing for individual panel optimization. This means that even if one panel is shaded or has a lower performance due to some reason, it won't affect the overall output of the entire system. They are easy to install, highly efficient in converting DC to AC power, and provide better flexibility in system design, making them suitable for both residential and small commercial solar installations.

Roof - Integrated Photovoltaic Power Stations

A roof-integrated photovoltaic power station that seamlessly blends with the roof tiles, creating an aesthetically pleasing and efficient energy solution.

Roof - integrated photovoltaic power stations combine the functionality of solar power generation with the aesthetics of building design. These stations are custom-designed to fit directly onto rooftops, replacing traditional roofing materials in part or in whole. They not only generate clean energy but also enhance the overall look of the building. With advanced installation techniques and durable materials, they can withstand the elements while providing a long-term and reliable source of electricity, making them an ideal choice for both new construction and retrofit projects.
