Every household spends thousands of rupees each year on electricity. Solar energy provides a sustainable and readily available source of power, but not everyone can afford the heavy upfront installation costs. So, many people do not go for solar Rooftop Solutions. However, the installation costs should be considered as investments as the solar panels have a lifespan of about 25 years during which they usually do not bring any maintenance costs. Here are seven advanced solar-powered pieces of equipment which every household can benefit from.

Here is one thing. Fossil fuels and nuclear fuels are used in power plants. These are heat engines. That’s right. Even though using nuclear fuel, be it uranium or hydrogen, these heat engines add lots of heat to their local environments. Those big towers are cooling towers that take heat out of the superheated water and release it into the atmosphere, usually into a nearby stream or lake. This added local heat can be very detrimental to the local ecology.

Only solar power has the nice feature that it adds no more heat to the environment than the sun would have shined onto the earth anyway.

A great source of information on this subject is the delightful little Dover book by H. C. Van Ness titled Understanding Thermodynamics.

The report also gives the impression that solar power is going to be cheaper than power generated by thermal power plants. While it is true that the cost of solar power has been coming down, it is necessary to understand certain aspects of solar power, particularly regarding its impact on the overall cost of power supply, so as to be able to take informed decisions without being carried away by some simplistic facts. ...
