With the cost of electricity rising 10-15% every two years, you may be considering alternative sources of energy, such as solar. But before you go and install a solar system on your house, some major disadvantages need to be weighed in.
You may think that Solar panels have evolved and gives you best performance with latest technology. But in reality, solar panel have low efficiency.
Even if you’re in a prime location you will be lucky to get around 22% conversion rate, with the best and most expensive solar technology available. Which means you get very little energy out of the roof top invested into Solar.
Then there is the reality of the solar panels being damaged by strong winds or becoming almost non-functional after 10-15 years of usage. Solar panels can not be repaired easily, on top of the cost of replacing the solar panels, the panels have to be handled and disposed of properly due to the toxic compounds used inside. Almost all the panels in India end up in land-fills, causing the huge environmental hazards. Recycle could be a possible option but PV waste recycling is still at a nascent stage globally, both in terms of technical standards and physical infrastructure. and at present, PV module recycling is not commercially viable.
- Installation Area:
Big houses and companies that want to produce a lot of power are going to need a very large installation area to provide electricity on a consistent basis.
- Environmental Impact:
Compounds found in solar panels is cadmium and lead, extremely toxic metals. There are a number of other toxic materials used including gallium arsenide, copper-indium-gallium-diselenide etc.
The most efficient solar panels convert only 22% of energy into power, so the land needs can be huge, and unlike with wind power, sharing the land for gardening/agriculture is not an option.
Solar energy relies on the sun, and generation is not reliable and consistent over months, you need to depend on grid electricity or add a wind turbine for dependable electricity.
