The solar panel price in India has been falling for several years. On this page, you can find out how the development is to be assessed for the coming years and how you can benefit from it.
The price of solar panels varies depending on several factors. Some of these important factors are:
- Type of solar panels (thermal or photovoltaic)
- Type of technology used (monocrystalline or polycrystalline)
- The size of the panels
- Quality of the collectors
- Quality of the glass
- The resin
- The thickness frame

The annual operating costs of a solar power plant are comparatively low at approx. 1% of the investment costs and the financing costs are also low due to the current low-interest rates. The dominant share of costs for solar power plants, the investment costs, has fallen by an average of approx. 13% per year since 2006 thanks to technological progress, scale and learning effects, a total of 75%.
How to Choose the Solar Panels for Your Home?
A solar panel transforms the sun’s energy (solar radiation to be precise) into electricity for an efficiency of around 20%. That is to say that if the sun sends an energy of 1000W per square meter – which is the case in summer in India, the solar panel is then capable of producing 200W of electrical power per square meter. In India, a single square meter of solar generates around 250 kWh per year of electricity production. Not bad is not it?
So it is therefore not necessary to cover our fields with solar panels, our roofs are more than enough … and in self-consumption, it is even more effective.
1. Solar Panel Brand
We encourage you to check that the brand of the solar panel is known, in the top 20 global brands, or referenced by a major distributor specializing in solar.
It is the job of the large distributors to select quality modules. You can check the products listed on their website. There are many brands of solar panels.
When it comes to solar panels, we encourage you to do as you do when you choose the brand of a smartphone: the big global brands are a little more expensive but are generally more reliable than the small brands unknown to the general public.
2. Solar Panel Type
It is best to choose a classic crystalline solar panel. It is more reliable, more easily recyclable, does not consume rare earth, or products that may one day miss us and better respects the environment.
There are several types of crystalline photovoltaic modules:
- Polycrystalline Solar Panel
- Monocrystalline Solar Panel
Mono solar panels are the most common type of solar panel. Indeed, 95% of the market is made up of crystalline solar panels, a classic technique invented by a Frenchman in 1839 by Antoine Becquerel. This technology is very reliable (40 years of service life), more than 95% recyclable. Its manufacture impacts the environment in the same way as a conventionally manufactured object. This technology is mastered and progresses every year. It is a choice that will make you take the least risk.
3. Solar Panel Installation
Even the best module in the world will perform poorly if installed incorrectly. A few simple rules to follow during solar panel installation allow you to put the odds on your side.
- Do not step on the solar panels. It resists hail (see details above), but like all of us, they hate being walked on. This causes microcracks which shorten the life of the cells.
- Do not make loops with the cables which supply the modules because, in the event of lightning near you, these loops can generate high currents that cannot create fire but which may damage your solar panels.
- Well ventilated, the module produces more. This is good because in self-consumption the solar panels are placed on the roof above the tiles (what is called over-taxation) and more inside to replace the tiles; which reduces the risk of yield losses.
- And of course, avoid putting the solar panels in an area that may throw shade. If you can not avoid it, use micro-inverters.

All About Solar Panels
Solar panels are very solid and have a very long lifespan. There are no moving parts, so no mechanical wear. It’s the only product I know of that has a 25-year manufacturer’s warranty. Solar panels over 40 years old still work on islands in Japan and the United States.
They are resistant to wind, rain and hail. The special glass used on the solar panels is toughened and laminated. The solar panel is factory tested to be MNRE approved. These tests, which meet the MNRE standard, are carried out with ice balls with a diameter between 1.25 and 0.75 cm, the impact speed is 140 km/m maximum. Suffice to say that the possibility of destruction of solar panels by hail is relatively low.
So in conclusion, the only thing that can overcome a solar module is a meteorite, but if that happens, you will have other concerns than checking the mechanical strength of your modules.
A solar panel is made of 75% glass . An infinitely recyclable material, just like the aluminum that makes up its frame. Inside there is an EVA plastic film which can be transformed into granules to be remelted or burned to generate electricity. Finally, there are the silicon cells and the electrical conductors which can be aluminum, silver or copper. These elements are separated mechanically and chemically before being melted, then reused.
