Rooftop Solar Solutions


In recent years, rooftop solar solutions have gained popularity as a sustainable and efficient way to harness the sun’s energy. With the world shifting toward renewable energy sources, rooftop solar systems offer a compelling alternative to traditional energy sources. We’ll walk you through rooftop solar solutions, discussing the benefits and what to consider before setting them up.

What is Rooftop Solar?

Rooftop solar refers to the installation of solar panels on the roofs of buildings, typically residential or commercial. These systems convert sunlight into electricity, providing a clean and renewable power source. Unlike traditional power sources, rooftop solar systems do not emit harmful pollutants, making them a popular choice for eco-conscious individuals and businesses.

Types of Rooftop Solar Solutions

Rooftop solar solutions come in different configurations, depending on your energy needs and preferences:

1. On-Grid Solar: On-grid solar power system is a solar power generation system where it is connected to the utility grid. The electricity produced by the system is routed to the grid from where it is used to run the various appliances. The excess power at any point in time is transmitted back to the grid.

2. Off-Grid Systems: Off-grid systems are installations not connected to the electricity grid: all the energy produced is stored and used on-site.


3. Hybrid Systems: Hybrid solar panel systems are similar to a grid solar system but use batteries to store energy for later use. This ability to store energy enables most hybrid systems to also operate as a backup power supply during a blackout, similar to a UPS (Uninterrupted Power Supply).

Benefits of Solar Energy

Solar energy offers a range of benefits, both for individuals and the environment. Let’s delve into some of the key advantages.

  • Solar energy is the most abundantly available energy on earth: Enough sunlight reaches us every 15 minutes to power the world for an entire year. And solar energy is a reliable way of power generation, at present, countries, and regions around the world have a large part of their energy from solar power generation.
  •  Solar energy is more secure and clean energy on earth: Using solar energy can achieve substantial carbon emissions, reduce disputes and promote human development.
  •  Solar power is a kind of flexible energy: Solar power is available wherever there’s sunshine. You can install solar panels on the roof or on the ground. The electricity produced by solar energy can be supplied to a family or an entire city. Solar power can also solve the problem of electricity in the world’s 1 billion 500 million non-electricity population.
  • Solar power is still a reliable investment: Project developers, owners, and owners of the land can sell solar power to the power company, so they can obtain a stable income during the entire life cycle of the solar system. Whether your solar power is for personal use or for sale, you can get a good return in the near future. As the cost of solar systems continues to lower, solar energy becomes a more and more wise investment. The reliable performance of our solar products will help you gain a profit in the coming decades. In addition, solar energy does not produce noise, no moving parts, and almost no need to maintain.
  • Solar power can satisfy the growing energy needs of mankind: The International Energy Agency report shows that the global electricity demand will be expected to increase to 31 trillion and 700 billion degrees by 2030. IEA pointed out that more than 66% of the world’s electricity is generated by coal, natural gas and oil, and other fossil fuels. When fossil fuel reserves continued to decline and power consumption continued to rise, so electricity prices will continue to rise. Then there is an urgent need to develop sustainable alternative energy sources.
  • Green Light Energy is the most perfect energy solution provider: Green Light Energy is committed to providing smarter energy solutions. Our dedication to producing top-quality, high-performance products is reflected in our world-successful stories and the most extensive customer satisfaction.

How Rooftop Solar Systems Work?

Understanding how rooftop solar systems work is crucial for making informed decisions about installation. Let’s break down the key components and how they function together to produce electricity.

Key Components of Rooftop Solar Systems

Rooftop solar systems consist of several essential components:

  • Solar Panels: These are the heart of the system, capturing sunlight and converting it into electricity through photovoltaic cells.
  • Inverters: Inverters convert the direct current (DC) generated by the solar panels into alternating current (AC), which is used to power your home or business.
  • Mounting Systems: These systems securely attach the solar panels to your roof, ensuring they remain in place despite weather conditions.

Factors to Consider Before Installing Rooftop Solar

Before diving into a rooftop solar installation, there are several factors to consider to ensure a successful and efficient system.

1. Tariff Scenario of Bangladesh

  • Overall Tariff Rate Increase-128.5 %.
  • On average 9.6 % per Year.
  • Presented price excludes VAT and Others.

2. Payback Calculation For 1MWp System

  • This system will generate 4100 kWh electricity per day(4.1H X 1MWp)
  • Annual Saving on electricity bill: Approx. BDT Tk.1,11,75,000
  • Payback will be in approx. less than 5 years @ Tk. 8.5/kWh.
  • However, if we consider the cost of production with a diesel generator, then payback will be even earlier.
  • Solar lifetime is 25 Years. After 6 years, all the energy savings will add to the owner’s benefit.
  • In the rest 18 years’ savings will be approx. 20 crore at a constant kWh rate of 8.5 Tk. However, it will be even more beneficial with rising energy prices.
  • CO2 Savings: 19,000 tonnes (approx.) during its lifetime.

3. Return on Investment

Rooftop solar systems offer a strong return on investment over time. The savings on energy bills, combined with potential income from selling excess energy back to the grid, can lead to a positive ROI within a few years.

Rooftop Solar Solutions: Harnessing the Power of the Sun

As renewable energy becomes increasingly important, rooftop solar solutions are poised to play a significant role in shaping our energy future. With the benefits of reduced environmental impact, economic savings, and energy independence, rooftop solar offers a compelling solution for individuals and businesses alike. By addressing the challenges and making informed decisions, you can harness the power of the sun and contribute to a more sustainable world.

Rooftop solar solutions provide a sustainable and cost-effective way to harness the power of the sun. With numerous benefits and a promising future, they offer an attractive option for those seeking renewable energy sources. By considering factors such as roof condition, local regulations, and financial aspects, you can make an informed decision about installing rooftop solar. As technology continues to advance, the potential for rooftop solar only grows, making it a bright solution for the energy needs of tomorrow.

FAQs about Automatic Swing Gate

The cost of installing rooftop solar varies based on factors such as system size, location, and quality of components. On average, installation costs can range from ৳10,000 to ৳30,000 for residential systems.
