What Is a Solar Rooftop?

Solar rooftop is a solar panel installed on the roofs of buildings that are either commercial, institutional, or residential. The sun’s light energy is captured and transformed into electrical energy. The term solar rooftop photovoltaic system is another name for this configuration. It generates a clean, environmentally friendly source of energy, which means that it doesn’t generate any kind of pollution or dangerous gasses. The global solar industry is poised to transform our planet into a safe and secure place to live. A rooftop solar system simply needs room and plenty of sunlight to function well, and on days when the sun is downcast, batteries stored in the panels can save the day.

Solar Rooftop in India

The rapid spread of rooftop solar panel installation for homes, buildings, schools, government buildings, and even businesses, i.e. Solar panels for commercial use, solar panels for office buildings, and solar panels for homes, is indicative of India’s transition to affordable, dependable, and clean electricity.

One of the nations that has achieved the highest renewable energy generation is India. In India, renewable energy sources account for 35% of installed power generation capacity as of 2019, or 17% of the nation’s total electricity production.

Rooftop solar energy adoption is currently increasing in India. With a compound annual growth rate (CAGR) of 116% between 2012 and 2018, rooftop solar in India has been the fastest growing renewable energy sub-sector from a historically low base.

The World Bank is supporting grid-connected rooftop solar projects with US$625 million in order to help the Government of India reach its ambitious goal of 227 GW (it was previously 175 GW).

Factors Needs to Consider for Rooftop Solar Installation

Understanding your electricity bill is the first step before solar panel installation on the rooftop. Look at how much energy you use each month in kilowatt-hours (kWh) to know how big of a solar system you’ll need.
Calculate the size of the solar panel system by considering the wattage of your appliances and how long you use them daily.
Make a list of the equipment you’ll need for the solar system, like solar panels, a charge controller, wires, an inverter, and more.
Make sure the area where you’ll install solar panels on the roof gets plenty of sunlight and is clear of any shadows.
Select the best rooftop solar installation company that offers different models, fits your budget, and meets your needs.
Check your building’s structure, energy use, and sunlight exposure before installing solar panels.
Plan your budget by considering rooftop solar installation costs, equipment, warranties, and maintenance.
Decide if you want your solar system connected to the electrical grid or independent. This affects what type of equipment you’ll need.
Get permits and look for any grants or subsidies available for solar panel installation on rooftops in your area.

How to install solar panels on roofs?

Let’s break down the process to install solar panels on roofs into simple steps for homes.

Mounting the Solar Frames:
- Start by installing the frames that will support your solar panels. These frames should be tilted at an angle of 15 to 20 degrees for maximum sunlight exposure, especially facing south in the Northern Hemisphere.
- For slanted roofs, use a railed system that attaches rails to the roof with screws and bolts, sealed to prevent leaks. For flat roofs, use ballasts or concrete blocks to support the panels.
- Make sure the mounting structure aligns with your design plans before proceeding.
Attaching the Solar Panels:
- Once the frames are in place, attach the solar panels securely. Line up the panels’ mounting holes with the rails and use stainless steel nuts, bolts, and washers to fix them.
- Maintain a small gap between panels to account for thermal expansion. Tighten the clamps between panels to ensure they are firmly connected.
Wiring and Connection:
- Follow electrical codes when wiring the panels. Use MC4 connectors and junction boxes to connect the panels either in series or parallel, depending on your system design.
- Series connections increase voltage, while parallel connections increase current. Ensure the maximum output voltage matches the inverter input voltage.
Connecting to the Inverter:
- Connect the positive and negative wires from the solar panels to the corresponding terminals on the solar inverter. Double-check polarity to avoid short circuits.
Off-Grid System Battery Connection:
- If using an off-grid system with a battery, connect the inverter to the battery terminals, matching positive to positive and negative to negative.
On-Grid System Grid Connection:
- For on-grid systems, connect the inverter to the main power switchboard, allowing excess energy to feed back into the grid.
Activating the Inverter:
- Switch on the solar inverter and monitor its display for proper functionality and real-time energy generation data.
Earthing for Safety:
- Ensure proper earthing for all components, including modules, inverters, and grid connections, using copper strips for better conductivity and safety.

FAQs:

What is a solar rooftop?

Rooftop solar refers to a photovoltaic system in which the solar panels that generate power are positioned on the roof of a home or business building or structure. These systems are photovoltaic modules, mounting systems, wires, solar inverters, and numerous electrical accessories. Megawatt-range capacity ground-mounted photovoltaic power plants are far larger than rooftop-mounted systems. Rooftop PV systems on residential buildings normally have a capacity between 5 and 20 kilowatts (kW), but those on commercial buildings typically have a capacity of 100 kW or more.

Is it safe to install solar panels on roofs?

Yes, it’s generally safe to install solar panels on a roof. However, it’s important to ensure that the roof is structurally sound and can support the weight of the panels. Professional installers will assess the roof’s condition and make sure it’s suitable for solar panel installation.

What is the cost of installing solar panels on roofs in India?

The rooftop solar installation cost in India varies depending on factors like the size of the system and the quality of the panels. On average, it can range from ₹50,000 to ₹70,000 per kilowatt, including installation costs.
