What is the advantages of Solar Energy?
- Sustainability: Solar energy is an abundant and renewable resource, making it sustainable in the long run.
- Reduced Electricity Bills: By generating your electricity, you can significantly reduce your monthly electricity bills.
- Low Maintenance: Solar panels require minimal maintenance, making them a hassle-free investment.
- Environmentally Friendly: Solar energy production has a minimal environmental footprint, reducing greenhouse gas emissions.
- Energy Independence: Solar energy systems provide homeowners and businesses with a degree of energy independence.
How Solar Energy Works?
- Absorption of Sunlight
Solar panels, also known as photovoltaic (PV) cells, are designed to absorb sunlight. These panels consist of semiconductor materials that have the remarkable ability to convert sunlight into electricity.
- Generation of Electric Current
When sunlight strikes the PV cells, it excites the electrons within the semiconductor material. This excitation leads to the creation of an electric current, which is then captured for various applications.
- Inversion of DC to AC
Most of our appliances and electrical systems operate on alternating current (AC). Therefore, the generated direct current (DC) must be converted into AC through an inverter to be compatible with our power grid and devices.
- Feeding the Grid or Storage
The converted AC electricity can either be sent directly to the electrical grid, reducing your energy bills through net metering, or stored in batteries for later use during the night or cloudy days.
What is the process of Installation of a Solar Power Project?
- Site Assessment
A professional assesses your property’s suitability for solar panels, considering factors like shading, orientation, and roof condition.
- Design and Permits
Based on the assessment, a customized solar system is designed, and necessary permits are obtained.
- Installation
Solar panels, inverters, and other components are installed on your property.
- Inspection
Local authorities inspect the system to ensure it meets safety and quality standards.
- Activation
Once approved, your solar system is activated and begins generating clean energy.
What is the lifespan of solar panels?
Solar panels can last for 25-30 years or more, with gradual declines in efficiency.
How efficient are solar panels?
Solar panel efficiency varies, but modern panels can convert about 20%-28% of sunlight into electricity.
Is it possible to store excess solar energy?
Yes, excess energy can be stored in batteries for later use.
Do solar panels work on cloudy days?
While their efficiency is reduced, solar panels still generate power on cloudy days.
Are there government incentives for installing solar panels?
Many State governments offer incentives and tax credits to encourage solar panel
installation .Central Govt has already declared incentives to encourage solar panel installation.
How long does it take to recoup the investment in solar panels?
The payback period for solar panels typically ranges approx.5 years, depending on various factors.
What is the Certification Provides from Govt.of India. which proves Quality Standard of Solar Panel?
In India, the Bureau of Indian Standards (BIS) provides certification for solar panels to ensure their quality and reliability. The relevant standards for certification of solar photovoltaic (PV) modules are:
- IS 14286: Criteria for crystalline silicon terrestrial PV modules (crystalline silicon PV modules).
- IS 16169: Criteria for thin-film terrestrial PV modules (thin-film PV modules).
These standards specify the requirements and tests that solar PV modules must meet to be certified under BIS. The certification process involves rigorous testing of modules to ensure they can withstand various environmental conditions, operate safely, and maintain performance over their expected lifespan.
Manufacturers of solar PV modules in India can apply for BIS certification to demonstrate compliance with these standards. Once certified, modules are marked with the ISI (Indian Standards Institute) mark, indicating they meet the quality standards specified by BIS.
It’s important for consumers and project developers in India to look for BIS certification when purchasing solar panels, as it ensures that the panels adhere to national quality standards and are suitable for use in various applications, including rooftop installations, solar parks, and other solar energy projects.
