Solar 101

The Basics

The sun provides more energy in an hour to meet the whole world’s energy needs for a year. While solar energy systems have been there for the past 10+ years, we have not seen mainstream adoption and scale as it should. With the advancement in technology, and more 10X reduction in the cost of electricity generation, it is now no longer a novelty factor, but a wise economic decision. Ultimately, it lets you save electricity bill, too.

  • During the day, solar cells in your solar panels absorb the energy from sunlight

  • Circuits within the cells collect that energy and turn it into direct current (DC) energy

  • The DC electricity is passed through a device called an inverter to convert it to the usable alternating current (AC) electricity that comes out of your wall outlets

  • This AC electricity output is either connected to the mains of your home, or stored in a solar battery to be used across your home or business

Components of a solar panel system

Solar panel installations are very straightforward systems. There are four main components to any Solar panel system with no moving parts. This makes them very efficient to install and maintain. The four components of a Solar panel system are:

Solar Photovoltaic Panels

to convert solar energy into electricity 

Inverters

to convert DC electricity into AC electricity 

Racking and Mounting Systems

to affix your solar panels to your roof (or to the ground, depending upon your installation type) 

Performance Monitoring Systems

to track and monitor the output and health of your solar panels and inverters

Solar Panel

A solar panel is a device that collects sunlight and turns it into usable electricity. Solar panels are usually made of solar cells (made from the element silicon), wiring, a metal frame, and a glass cover. The solar cells, which are also referred to as photovoltaic cells, absorb sunlight during daylight hours. For maximum effect, the panels are grouped together into “arrays” (an ordered series) – a typical solar panel is about 4 feet wide, and 6 feet tall.

Inverters

The cells in your solar panels collect the sun’s energy and turn it into direct current (DC) electricity. Most homes and businesses, however, use alternating current (AC). Inverters change the DC electricity from your panels into usable AC electricity. 

Solar Racking and Mounting Systems

Solar racking and mounting systems are the pieces of hardware that affix your solar panels to your roof or to the ground. 

There are two types of mounts: fixed mounts, in which the panels remain stationary, and tracking mounts, which allow panels to “follow” the sun as it moves across the sky during the day  

Performance Monitoring Systems 

Performance monitoring systems provide you with detailed information about the performance of your solar panel system. With a monitoring system, you can measure and track the amount of electricity your system produces on an hourly basis.  

The most frequently used inverters in the residential market all come with production monitoring apps so that you can track the output of your panels 

Types of Solar Installations

Residential Solar

Homeowners nearly anywhere can benefit from a solar panel installation on their property. In most cases, residential solar panel systems are rooftop installations on stand-alone, single-family homes, though it is possible to have ground-mounted, carport, or pergola installations at your home as well. Solar rooftop installation for home send the electricity they produce directly to your home, and send any excess back to the grid to offset your electricity bill via net metering.

Commercial and Industrial Solar 

Have you ever been in a window seat on an airplane looking at all of the empty, flat roof spaces on large buildings? (No? That’s just us? Cool.) Turns out these buildings, which are typically commercial or industrial businesses, are perfect for solar. Solar rooftop installation for business cover any type of solar installed on a business, from small and medium businesses to industrial factories, with installations anywhere from rooftops to parking lot canopies at shopping centers to wide open fields on a business’s property. Solar is a great option for businesses throughout the country, and it can even turn into a source of revenue for many companies.

Utility-scale Solar

Your electrical utility relies on large power plants to provide the electricity that flows out of the outlets in your home and business. These power plants have typically been powered by fossil fuels or nuclear energy; however, utilities are increasingly relying on large scale development of renewable resources–primarily solar and wind–to provide electricity. Utility-scale solar panel installations are massive–often between 500- and 30,000-times larger than a residential solar installation–and sell their electricity directly to utilities, meaning they can effectively provide power to tens of thousands of homes and businesses.

Community Solar

Community solar plays a unique role in making solar power directly accessible to people who can’t put solar panels where they live or work: instead of being installed on site at your home or business, community solar is a large-scale solar farm installed in your area that you can then subscribe to in order to purchase and benefit from the solar power generated at the installation.  

Why should you Go Solar

Solar is the way forward

The Solar energy is a game-changer when it comes to sustainable and renewable energy sources. Solar power has become one of the most prolific forms of renewable energy around the world, providing numerous benefits to homeowners, apartments and businesses.

ENVIRONMENT FRIENDLY

Solar allows us to power homes and businesses with clean, safe energy from the sun, and helps fight climate change, combat greenhouse gases and reduces our carbon footprint. We can help save our planet and provide brighter future for many generations to come.

USE LESS NATURAL RESOURCES

Most energy sources rely on finite natural resources. But given the massive amounts of energy used, this means that future generations will likely have little to zero natural resources left. Solar energy uses significantly fewer natural resources to produce.

ENERGY INDEPENDENCE

Solar allows you to take back control of your energy supply and gives you energy independence. Rather than paying your electricity retailer for your electricity you can generate your own and become self-sufficient with our battery storage options.

PROTECT AGAINST RISING ENERGY COSTS

Most utility companies use fossil fuels as the primary method for energy supply. The cost of the electricity is constantly increasing and is expected to continue, and solar helps in reducing the dependence on utility companies

ADD DESIRABILITY TO YOUR PROPERTY

Solar Power translates to a home with lower running costs and higher energy performance rating. Therefore when looking into property, for purchase or rent, solar power can be seen as an incentive to any potential investor.

Government Incentives

At COP 26, the Climate Change Conference in 2022, India reiterated its commitment towards renewable energy power generation.

India aims to achieve 500 GW renewable energy capacity by 2030. Solar is expected to be 280 GW, contributing around 55%.

For comparison, the capacity stands at 175 GW as on February 2023. Solar power leads it with 63 GW, followed by wind (42 GW).

To achieve this, the government has ensured favorable policy, launched incentives and subsidies, and commissioned many projects

Frequently Asked Questions

What factors affect the electricity generated from the rooftop solar panel system? Will it be the same all year round?2024-04-01T17:48:01+05:30

The generation of electricity from the rooftop solar panel system depends on many parameters such as –

  • Location of the rooftop solar (part of the country) 
  • Quality of equipment used  
  • No. of sunshine hours  
  • Temperature and irradiance (the strength of sunlight received) 
  • PV module tilt angle and orientation  
  • Module cleaning, and other maintenance activities  

The daily energy generation will be dependent on the weather conditions such as temperature, solar irradiance, etc., and these may not be same every day. 

What is the daily energy generated from a 1 kW solar panel system?2023-12-16T19:52:30+05:30

On a clear sunny day, 1 kWp solar power plant can generate 4 to 5.5 units of electricity in a day

(To compare, check the number of units consumed by you as seen on your electricity bill) 

What types of roofs are suitable for rooftop solar system?2023-12-16T19:50:06+05:30

Rooftop solar PV systems can be installed on any type of roof having sufficient load bearing capacity. 

Why do I need shadow-free area for my solar PV system?2023-12-16T19:48:15+05:30

Solar modules (and cells within) need uninterrupted sunlight to produce maximum electrical energy. With the shadow even on a part of the module, the generation reduces to a great extent thereby wasting installed system capacity. Also, prolonged (regular, though intermittent) shadow on some cells or modules reduces their life substantially and these become useless much before their standard life of over 25 years
