How much does cost to install solar panel?

Just like “every snowflake is different”, so is the energy needed for every home. A solar panel can be customized based on utility, location, and shading. In India, the price of solar panel systems may range from Rs.75-85/ watt.

A big sum of money can be saved if the solar energy required is well calculated. Following are the steps to conclude the amount of solar energy required or can be harnessed.

1)      Check the electricity bill:

The higher the electricity bill, the more the savings. Typically, a solar panel is installed on a rooftop to receive the maximum amount of sunlight. The electricity bill needs to give an idea about the fluctuation in energy consumption with varying seasons and events.

2)      Evaluate the cost of a solar panel:

A lump-sum investment in solar panels and components is still worth a span of 25 years. After 25 years, the output is minimally decreased if the panel is maintained well. A solar energy calculator is often used to calculate the amount of energy generated and savings made based on factors like location, rooftop area, and current electricity bill.   

In India, a 5KW residential solar system has an average cost of Rs 63 to 71.4/watt and a total of Rs. 3,15,000 – 3,57,000 with installation, before considering any government subsidy.

3)      Save money now, ask me how?

To support people to opt for green energy, Governments launch policies. One can apply for a subsidy and save chunks of money.

You can check details about the eligibility criteria and approved list of models and manufacturers of solar photovoltaic modules on the National Portal for Rooftop Solar launched by the Indian government.

The Government subsidy is available only for the residential sector grid-connected solar rooftop projects.

Where do I install the Solar panel?

 A suitable site receives a surplus amount of sunlight. The amount of sunlight received depends on factors like weather conditions, the average number of sun peak hours, the type of roof, shading, and latitudinal location.    

Choosing a suitable site is as crucial as choosing the right type of panel. Ideally, a panel is installed on the rooftop or mounted on the ground. Otherwise, they could be installed on the sides of a wall, as a rooftop overhang, a carport, a gazebo, or a carport. A Solarium or a solar pergola can be lavishly constructed for harnessing solar energy. A rooftop overhang can save a home from solar heat by up to 77%.

Advancements 

Currently, the advancements in putting in solar panels have been stretched making solar energy a lot more effective and cheaper. Advancements in solar panels, particularly PV cells and energy storage systems are improving the efficiency of the solar systems. 

Government Policies 

The power of solar development must be supported by positive policy measures at the federal and provincial levels. Solar energy is also cheaper because of incentives being offered like tax credits and rebates and feed-in-tariffs that make solar investments possible for businesses as well as for homeowners. 

Environmental Awareness 

Due to the awareness of people on the effects of climate change along with sustainability, clean energy is being sought after. Renewable energy, especially from the sun, is environmentally friendly as it barely generates greenhouse gas emissions and hence, fully supports the above environmental objectives. 

Falling Costs 

As technology penetrated the solar industry, it reduced the cost of installation across the board. This has kept the cost low, thus enhancing the readiness for greater consumption of solar power by a lot of buyers in the market. 

 

Should I buy solar panels?

 To buy a solar panel would prove to be much more profitable in the long term. Buying a solar panel increases the property value by 3-4%. However, a cash purchase may seem to be difficult in the current economic times. The other financing options could be a home equity line of credit or a solar loan.  

Economic Benefits 

The solar industry is playing its role in economic development by generating employment, investors’ interest, and developing a value-for-money approach to energy. Solar initiatives investment creates jobs for the people and stimulates innovation in the renewable energy platform. 

Environmental Benefits 

Environmental advantages that come with using solar power include cutting greenhouse gases and determination of fossil fuel. This form of energy is renewable and has a positive impact on reducing greenhouse gases, hence reflecting a positive stride towards a cleaner environment in Canada. 

As the consultations on the future prospects of solar energy in Canada come to a close, it is time to provide an answer to this question. 

Choosing the right one

Multiple factors help decide the right one for you. The amount of energy required, the budget, installation service providing vendors, are available to name a few.

 

Permits required

As the installation of solar panels involves certain electrical works and construction, it is mandatory to seek permits from local authorities. It is important to know if the municipality, county, or city has any jurisdiction over the property. The application to authorities should include a site plan, a schematic design of the system, a diagram of electrical writing, and certification of components used in the system. 

 

How to install solar panels step by step

To begin the process of installation, have the essential tools like a Chaulk gun, measuring tools, a sturdy ladder, safety equipment, a power drill, a power saw, and a flat pry bar. Make sure you are equipped with the electrical wiring, conduits, fitting, AC/DC connects, junction boxes, and breakers. 

To begin with the installation process, follow the How to Install Solar Panel step by step guide:

  1. Installation of rack:

 

Usually, a DIY solar panel kit comes with a racking system for the panel. Follow the DIY guide in the video:

  1. Installation of Inverters

If the solar system comes with microinverters, these inverters need to be attached to the back frame of the solar panel before mounting. The closer the location of the inverter to a solar panel, the better the efficiency.

  1. Installation of Solar Panels
  • Firstly, use the two end clamps to install the first panel on the rails. 
  • Next, make use of grounding mid-clamps to install each consecutive panel. The mid-clamps bind the solar panels and rails together, to form a continuous system.
  • On completing the installation of all panels, make use of two or more end clamps to secure the last panel on the rail.
 
 

How to connect solar panels to the house

 

To connect the solar panel to the house, follow the steps:

  • Connect the Solar Inverter to the Solar Battery:

A solar battery saves solar energy generated by solar panels. Hence, one need not worry about the lack of solar energy during the cloudy days.

  • Connect the Solar Inverter to the Consumer unit:

An inverter converts the Direct current generated by the Solar Panel to Alternating Current. This inverter is connected to a Switchboard. A switchboard enables the use of AC from the solar panel and allows the usage of electricity from the grid in the absence of solar energy. The switchboard is then connected to a Consumer Unit of the house for the distribution of the current for powering the electrical appliances. A utility meter, usually a bi-directional meter is connected to a Consumer unit. A bi-directional meter not only monitors the power drawn from the grid to the house but also the amount of solar energy exported back to the grid, called net-metering. On exporting the unused solar energy to the grid, you earn credits on the electricity bill. 

 

   What next?

After a successful installation of a Solar Panel, one needs to ensure the risk-free working of the system.

1)      Solar Inspection:

Contact your local building department and book an appointment to schedule the inspection of the system.

2)      Monitoring system:

A monitoring system is set up to keep a record of the energy produced. It is usually provided with a solar panel kit. The monitoring system is connected to the internet to send you notifications and alerts in case of a drop in energy production.

3)      Routine maintenance:

 

The panels may underperform in case of dust accumulation or micro-damage to the panel. Hence, routine maintenance can help to avoid a problem or diagnose it at an early stage.
