5 Things to Consider Before Installing Solar Panels | Freyr Energy

5 Precautions You Must Take Before Installing Solar Panels

Deciding to install solar panels on your roof is significant. Solar power is an excellent method to reduce your electricity costs and positively impact the environment, but there are several things you should know before switching to solar. The five key steps you should take before installing solar panels will be covered in this blog. By the end, you’ll be fully informed about what to anticipate and how to get ready for your new solar panels. Let’s start now!

Installation of Solar Panels on Roof

Here are our top 5 precautions before installing solar panels.

1) Make sure the roof is in working shape

It is advised to ensure that the rooftop is physically sound. These days, warranties for solar installations can last 20 or 25 years. It will be simpler to take care of any necessary renovations to your roof now rather than later when the panels are installed. In addition, your panels won’t need to be disconnected during the roof refurbishment and reinstalled, saving you time and money.

2) Make sure you have enough roof space for the panels to sit on

Is there enough room on your roof for installing solar panels? Typically,  80 square feet are needed to install 1kW of solar. Instead of a level roof, the optimal one for solar panels should have a sloping angle of 30 to 40 degrees. Thus the ideal option for solar panels is a sloping roof, but flat rooftops are just as fair. It is not suggested to install solar panels on clay or slate roofs since they tend to collapse. It would be best if you took extra precautions when you have a clay or slate roof.

3) Ensure that the property isn’t in a flood zone 

Building resilience and reducing the danger of damage from floods are the top priorities for solar providers. Floods will destroy an electrical grid, but solar energy offers novel solutions to these problems. Compared to conventional power grid solutions, solar systems feature advantageous positioning and stacking options. By mounting solar panels on rooftops, you can prevent flood damage and keep the panels out of harm’s way. Your solar panels will continue to power your house and business operations if catastrophic floods don’t reach rooftops or corrode wire systems. A solar system’s electrical wiring may suffer if the inverter is flooded. To avoid flood damage, high-quality solar panels include protective glass casings, vacuum-sealed rear panels, and sturdy metal frames. Additionally, depending on your location and environment, mounting and racking offer flexibility created for quality and sustainability. To prevent loss on your investment, it is advised to examine whether or not your property is located in a flood zone. 

4) Check if your property has enough sun exposure

Your roof may not have a good enough “solar window” to make the expense of panels worthwhile if it is shaded for most of each day all year. Ideally, the area earmarked for solar installation should be shadow-free from 9 am to 3 pm on any given day. Major obstacles that cast shadows can be trees & vegetation, water tanks, a nearby building, parapet walls, etc. Ensuring a shadow-free area is critical for the optimum generation of power from your solar panel installation.

5) Find out your state’s net metering rules

A single bidirectional meter called net metering needs to be connected to regulate the supply and import of electricity from the grid Net meter ensures you can get credited for the energy you export. The rules for net meters can vary from DISCOM.

Frequently Asked Questions

Solar power is a good investment for your home. It reduces your electricity bills. It also helps you depend less on conventional grid energy. On the top, you contribute to a sustainable environment. And, at least, your real estate gets a good value in case you wish to resell.

The average solar panel lasts 25 years. All you need to do is keep it maintained with frequent cleanings. To avoid unforeseen damages, check for any flaws in advance or hire a service provider for planned maintenance.

The environmental benefits of solar power installation are many. Solar power systems do not use fossil fuels. They do not pollute the air. Solar systems support environmental sustainability by keeping the air clean.

The roof must be in good shape and of durable quality. It must have enough space for technicians to easily operate while they set the solar panels for your home. In addition, the roof must receive plenty of sunlight.

The rooftop space depends on the solar system size. A regular rooftop space requires 335 sq. ft. A solar system having 10 kW capacities requires 1000 sq. ft. rooftop space.

The average cost of a solar panel installation in India falls between ₹1,00,000 to ₹6,00,000. The final price depends on the size of the system, component quality, and the vendor company. Solar panels for home cost may be reduced with government subsidy.

Yes, consider the following safety precautions for solar power panels installation.

  1. Ensure proper grounding is done.
  2. Ensure the roof is durable enough to sustain the panel’s weight.
  3. Avoid using damaged modules and incompatible connectors.
  4. Ensure the technician is trained and doesn’t leave any termination half-hazard.
  5. Ensure the solar rooftop company implements appropriate fall protection and other safety systems.

Understand the following before installing solar panels for your home.

  1. Quality of solar system components such as the Solar Panel, Charge Controller, Battery, and Inverter/UPS.
  2. Check your roof meets suitable requirements, such as required space, orientation, and tilt, receives ample sunlight, and is strong enough to sustain the solar panels.
  3. Assess your energy requirements, how much energy you consume, how much you will require in the future etc.
  4. Understand local regulations and permits are procured before the solar system installation starts.
  5. Ensure appropriate safety protocols are followed during the solar panels and installation.
  6. Check the warranty offered on solar panels for your home

Risks associated with solar panels are:

  1. Harsh weather such as strong winds, lightning, etc. can damage solar panels.
  2. Micro-cracks may develop in the solar panels due to strong wind. It reduces their efficiency and life. Dust and water may enter these cracks, damaging them further.
  3. Solar panels are vulnerable to theft if not secured appropriately.
  4. Solar panels if they do not follow local guidelines and regulations may result in modifications that may be expensive.
  5. You may have to put in additional costs if you need to replace or repair the roof.

The basic three precautions for electrical safety are:

  1. Avoid contact with water when working with electricity.
  2. Check the electrical periodically to identify any signs of damage.
  3. Do not overload electrical circuits and outlets.

A net metering program allows solar panel owners to provide their extra electricity to the grid. This extra energy is then credited to the solar owner’s account and helps them offset the electricity grid they use from the grid. It thus helps in reducing the electricity bill further.
