A Detailed Guide to Running your Home on Solar Panels

Why wouldn’t everyone want to turn their family farm into a solar-powered operation? Photovoltaic cells are used in solar panels to capture solar energy and turn it into electricity. After the initial cost of installing the system and your ongoing maintenance expenses, solar energy is completely free. It is entirely feasible to power a home entirely with solar energy. So it makes a lot of economic sense to power your home with solar panels. 

Plus, solar energy is effective and pollution-free. 

However, if you choose to live entirely off the sun, you may have to deal with bad weather, which could interfere with your goals. But when society’s ultimate goal is to phase out the use of fossil fuels, shut down fossil fuel-powered utility corporations, and live a solar-powered life, the only way to make that happen is by mass adoption for solar panels. 

Why install solar panels? 

Solar panels for home owners are becoming an increasingly appealing choice. This is due to the fact that solar panels are low-maintenance, offer a safe return on investment, are an economical way to reduce energy usage in the home, and are ecological.

Of course, since solar panels produce power using the sun’s natural, renewable energy, they are also highly environmentally beneficial. 

The other obvious incentives are – solar energy is clean and does not produce greenhouse gasses, carbon dioxide, or other damaging pollutants, in contrast to non-renewable fossil fuels like coal and oil. By utilizing solar energy, we can lessen our carbon footprint, enhance our health and quality of life, and keep the world from being destroyed. Using solar panels, you might reduce carbon emissions by over two tonnes annually and contribute to the meeting. You can save money by using solar panels as well. Solar energy is free to use after the initial installation fee, which is decreasing. 

As solar energy could meet all or the majority of your entire energy needs, you will save money on energy bills since you will consume less energy from your supplier. You mayeven  make money with solar panels in addition to saving money. On many electric grids across the world, you are compensated for all the electricity you produce as a result of the government’s feed-in tariff. If you decide to sell your home, installed solar panels will raise its value and even increase the likelihood that lenders would approve a loan. 

Additionally, solar panels don’t need to be maintained. They are durable and require little maintenance, but you will likely need one professional check every year to make sure they are still operating well. The inverter needs to be replaced after 20 years, although solar panels can endure for over 20 years with minor upkeep.

How to install solar panels in your home

Before you begin – weigh your options, and then only estimate how much electricity you will need once your home has a solar power system installed. With the use of solar calculators, you can rapidly calculate how much the solar panel installation cost will be at your home after calculating and figuring out what kind of solution meets your ideal rooftop solar design parameters.
Be sure to take the system’s lifetime, warranty, and maintenance costs into account. 

Once your spending range has been established, it’s time to find a reputable solar supplier. Because a solar plant is a lifetime investment and you wouldn’t want to have to run from one place to another in the event of a breakdown, investigate the solar firm you intend to get one from. 

Then conduct a site study to determine the best location for photovoltaics, any obstacles, the size of the central electrical panel inside the home, and locations for installing electrical components, condition of the rooftop, appropriate square footage for module positioning. 

You will receive a proposal from your solar business after completing your site assessment and calculating the building’s average consumption. Choose a solar power plant after carefully weighing its technical and financial needs. With a solar panel roof for the house, there is a tonne of paperwork required, just like with any large financial decision. 

Permits can be required for on-grid networks if you choose to use net metering or gross metering. Permits often vary from state to state in several nations, and depend on the type and size of solar panel assembly. The solar panel roof will first be prepared by the solar developer. It would guarantee that the panels are properly fastened. The electrical cable that connects to your electrical panel and primary power system is then installed by the solar provider. 

Solar panels for homes often come with a 25-year warranty. Generally, the corporation would provide 10 years for performance at 90 percent, and fifteen more years for performance at 80 percent.

Types of solar panels:

Solar panels for home come in three main varieties: thin-film, polycrystalline, and monocrystalline. The solar panel type that is suitable for your installation will depend on elements particular to your own property and desired system characteristics. Each kind has its own distinct benefits and drawbacks.

  • Monocrystalline solar panels are perhaps the most expensive form of solar panel available. This is primarily attributable to the manufacturing process; as solar cells are created from a single silicon crystal, producers must pay for the crystals’ production.
  • Polycrystalline solar panels are less expensive than monocrystalline ones. This is due to the fact that silicon fragments rather than a single, pure silicon crystal are used to make the cells. This makes it possible to manufacture cells considerably more cheaply for both manufacturers and ultimately end users.
  • In general, CdTe solar panels are the least expensive to make, while CIGS solar panels for home are significantly more expensive than either CdTe or amorphous silicon solar panels. Due to the generally higher manpower required, installing a thin-film solar panel system may be less expensive overall than installing a monocrystalline or polycrystalline solar panel system. Due to their reduced weight and greater maneuverability, thin-film solar panels require less work during installation because they are simpler for installers to take up onto rooftops and fasten. As a result, labor costs will be lower, which will help make the entire cost of a solar installation lower.

What to keep in mind when installing solar panels

  • Pick the best solar panel brands and inverters for your needs. There are numerous varieties of solar technology available. The solar system also includes an inverter in addition to solar panels.
  • You can measure your energy use with the aid of a reliable solar contractor. To determine how much energy you need to create with your nearby solar system, this is essential.
  • The government offers advantages to those who want to install solar panels in states all over the world. Investment incentives that partially cover the cost of solar panel installation. You can sell the solar electricity you generate to the utility company running the grid through feed-in tariffs or net metering.
  • When there is direct sunlight, solar panels operate most effectively. Evidently, solar powered boards facing east and west throughout the day produce less energy than those facing toward the equator.
  • Solar batteries function and serve as a backbone, allowing you to survive without electricity for extended periods of time or for just a little period.
  • The level of solar specialists you select will have a direct impact on the overall efficiency and quality of the outcome.

What is the best solar system for a home? 

The particulars of your property and situation will play a significant role in your choice of solar panel type. Installing less efficient, less expensive polycrystalline panels can help property owners with lots of room for solar panels save money up front. Installing high-efficiency, monocrystalline solar panels for home will help you reduce your electricity costs to the fullest extent possible if you have a small amount of available space. 

When placing solar equipment on a large, commercial roof that cannot support the added weight of conventional solar equipment, thin-film panels are typically the choice. Thin-film panels’ lower efficiency can also be tolerated on these kinds of roofs because there is more space for them.

What are the main components of a solar panel system?

There are 8 basic parts that make up a solar panel:

  • The foundation of solar panels are solar cells. A solar panel is composed of thousands of cells. 
  • Soldering, encasing, mounting on a metal frame, testing, and other processes are used to connect these solar cells to create solar panels. The efficiency of solar cells and solar panels are inversely correlated. The overall effectiveness of the solar panel is influenced by the price and performance of solar cells. 
  • The solar panel’s outermost layer which is the solar glass, needs to be strong and glossy to work at its best. Solar glass’ primary purpose is to shield the solar cells from inclement weather, sand, and dust.
  • The cells are enclosed in a highly transparent coating called “ethylene vinyl acetate.” To keep the cells together, it provides laminated layering on top of them. 
  • The panel’s rearmost layer, the back sheet, offers both mechanical and electrical insulation. The panel’s aluminum frame gives it structural stability. It should be rigid and strong enough to withstand adverse weather, such as strong winds and outside pressures. 
  • The panel’s backside is fixed with a junction box. It is the main location where cables attach to the panels. Solar panels can connect to one another with the aid of interconnectors. 
  • A solar panel’s adhesive is made of silicon. Strong bonding can be made with silicon, which also resists chemicals, moisture, and the elements.


Pros and cons of running your home on a solar panel

Pros: 

  • The sun and all of its heat and light will continue to exist for billions of years. We can use the sun as a renewable, environmentally benign source of fuel for the rest of our lives because we will never “use up” its power.
  • By starting with a lease or power purchase agreement, homeowners can partially or completely offset the costs of installing solar power.
  • It requires little upkeep after your solar panel installation is installed. Homeowners may be sure their solar panels will produce electricity every day by cleaning the panels perhaps just a few times a year.
  • Innovation in the solar industry is ongoing. Solar panels should become more effective with time.
  • It can be utilized in a variety of settings, including your house where it can run all of your equipment more affordably and in rural places where there is no grid to rely on.

Cons:

  • Solar panels don’t receive sunshine constantly, which is irregular. Solar electricity cannot be produced at night, and it produces less power in the winter or when it is very cloudy and raining.
  • Batteries and other forms of storage can be very pricey, despite the fact that solar components are becoming more affordable.
  • Solar energy is clean energy, however some solar panel makers may release damaging greenhouse gasses during the production process.
  • The special characteristics of solar panels frequently necessitate the usage of uncommon materials. So, everyone needs to be aware of the expense associated with capturing the ‘free’ energy from the sun.
  • Power density provides a rough indication of our ability to afford an energy source’s cost and determine whether it can satisfactorily meet our needs.

The cost of solar panel installations

The price of the panels alone could range from Rs 30 to Rs 50 per W. A typical PV system contains wires, batteries, and an inverter. In general, greater capacity PV modules cost less per Wp than lesser capacity modules. Grid-connected PV systems cost between Rs 50,000 and 75,000 per kWp, and the price varies depending on the inverter and panel type selected. Solar PV systems for off-grid homes typically cost around Rs 1,000,000.

Conclusion

The greatest quality solar panel system will require a significant investment. But it will also have a 25-year warranty. Therefore it is crucial to inspect the quality and understand every component that was used in its creation. In order to avoid being duped into purchasing subpar parts, buyers should be knowledgeable of the many components used in the construction of a solar panel, their roles, and how it operates.
