Pay your attention toward the energy it generates per year: 2,500 kWh
This is the energy needed for a 285 W device to run 24X7X365.
This energy is generated while conserving the beauty! Isn’t it great!
In terms of money: If 1 kWh costs $ 0.12, then the annual savings from the electricity bills would be $ 300.
This leads me to think more about Solar Energy.
If you use a 2500 W solar panel system (which would cost you about $ 6000 – for a Gird-Tied system with no battery and about $ 10000 with battery storage), annual savings would be around $ 1,200. It will take up to 5 to 8 years to cover up the cost. But, for a system with batteries, you will have to replace the batteries after 8 years. Which means, it won’t be a profitable investment (in terms of finance) even after 8 years for a system equipped with battery storage.
There are few challenges for us:
1. Increasing the efficiency of solar panels while keeping them easily mountable (if possible flexible and transparent), light weight, and cost-effective. We should decrease the price per Watt investment*.
2. Increase the efficiency of the batteries and their life span while the production cost of the batteries be lower. Or else, we should be able to produce the batteries with the current efficiencies and life span for a very low-cost.
3. If we accomplish above two challenges we will be able to meet future energy needs. Can we call our selves “successful” by simply addressing the energy needs? What about the environment? What would be the side effects? Will the manufacturing process harm the environment? What would happen to the used batteries? What would happen to the damaged solar cells? Will they harm our environment? We should address the challenge of protecting the environment as well. Otherwise, we cannot be called “successful” even if we address the energy issue.
Fulfilling all the 3 challenges should be our challenge. Not just one of them.
Are we ready to take up the challenge?
Solar energy… it is our future energy source. It was our ancient energy source. Even though you do not realize… it is our current/present energy source as well!
Let’s create a better tomorrow!
* – investment or cost? – I always see it as an investment. An investment for a better future.
