8 things to know before buying solar panels

Save Money, irrespective of your budget

Sun is a free source of energy. Converting solar energy to electricity is not just environmentally friendly, but is also very economical.

You can cut down your electricity bill by 90% or more depending on your electricity consumption. Even with a low budget, you can now go solar as Freyr Energy has introduced financial assistance ensuring that customers can own a solar system with little to no upfront cost.

Things to Know Before Buying Solar Panels

Solar panels have been around for a long time

Solar photovoltaic technology in particular was first investigated in year 1839 and more than a century later in 1954, scientists in Bell Labs invented solar cells that can generate electricity. With the advancement in technology and production techniques, solar panels have come a long way in the past 65 years. The efficiency of solar photovoltaic cells has improved drastically with advanced solar cell technologies like perovskite with efficiency reaching 40%, these are getting better and better.

Solar panels are highly durable

Solar panels are composed of solar cells connected in series and parallel connections which determine wattage of a solar panel. These solar cells are sandwiched between tempered glass at front and tedlar or back sheet at rear. Between the solar cell, front glass and rear tedlar layer are encapsulated which binds these layers together to form one panel. The solar panels are designed and made to meet international standards and withstand hail, snow and high winds.

Solar panels can produce electricity for 25 years

Solar panels can generate electricity for 25 – 30 years. So once you recover your initial investment through reduction in electricity bills within the first 3-4 years, you will generate electricity for free for your lifetime.

Solar panels are maintenance free

If you drive a vehicle, you know the service costs associated with it. Solar panels once installed will sit there for their lifetime. There is zero maintenance cost for a solar system. The only maintenance work is to wipe dust off the solar panels to improve their efficiency.

Solar panels can be installed anywhere

If you have shadow free space facing south on your roof, garden, barren land, ponds and lakes, solar panels can be installed. For a 1kW solar system, approx 80 sq. ft of shadow free space is required.

Solar system is tied to electricity grid

Solar systems can power your home on its own with batteries but it’s a costlier option. Solar system tied to the grid is a better option and is called on-grid solar system, especially if you have a reliable grid connection. With an on-grid Solar system, extra electricity that is generated can be supplied to the local electricity grid. The units that are exported to the grid are credited to the billing amount of grid electricity, thereby reducing the electricity bill.

Solar panels can be installed in homes, offices and factories

Solar panels can generate electricity to power homes, offices and even factories. The size of the solar system is defined by the loads connected to it and it’s usage pattern. Free electricity and other financial and environmental benefits add up to the value of the premises. Solar systems can power factory machinery with heavy loads at ease.

Conclusion

With all this information you might feel encouraged to install solar system at your premises. This will save you money and give you energy independence. However, it is necessary that the right equipment is used for your solar system. We at Freyr Energy always aim to provide the best quality and service for our customers.

Frequently Asked Questions



Before even deciding to go solar, it’s important to have the knowledge on savings. It is the most important thing to know before buying solar panels and eventual usage. Depending on the consumption, you can save up to 90% of your current bill amount.

Not really. Despite having a slightly steeper initial cost, the overall price of panels is justified thanks to the quick 3-5 years ROI it assures on power savings. Even then, companies like Freyr Energy offer you solar system finance assistance that ensures customers can go solar with little to no upfront cost.

Solar PV panels were first introduced in the year 1839. About a century later in 1954, scientists in Bell Labs invented solar cells that generate usable electricity. Over the last 65-70 years, technology has improved immensely and this has led to the production of even 40% more efficient systems like what we have today.

Solar panels contain solar cells that are connected in series and parallel connections. This determines the wattage of a solar panel. These cells are sandwiched between tempered glass in front and back of the sheets. In the middle of a solar cell, the front glass and rear tedlar layers are combined and bonded in a way to form one solar panel. These panels are highly durable and resistant to several weather conditions.

Yes. The maintenance includes simply wiping the dust off the panels at least once a month. That’s it, in theory, it is a zero-maintenance system.

Solar panels can be installed on rooftops, in open spaces, or in gardens. All it requires is an average of 80 sq. ft space for a 1 kW system.

Solar panels can generate sufficient electricity for homes or offices. This is determined using the load and consumption of systems of different sizes.

An on-grid system is one where panels are connected to the main power grid. The system is further altered with the help of net metering. With this, any extra power generated by solar panels can be sent back to the grid, and in turn, the panel owners can make money via DISCOM giving out credits and discounts on the bills.

Yes. One of the main solar panel considerations one needs to be aware of is the number of heavy machines they are about to use. With a sufficient understanding of monthly power and load consumption, panels can be installed of the appropriate size.

Freyr Energy delivers with a promise of having the best-quality solar panels with reliable service and assurance to every single customer to date.
