Speaking Eco Green

Solar Cells & Solar Panels is only the first part of a Solar Power System.  The ” photovoltaic effect” is a process of which solar cells convert sunlight into electrical energy that can be used.

In the early days of solar cells they could only convert 1-2% of sunlight into energy, but today with new technologies they have increased solar cells to convert sunlight into energy by 15-20% .   By increasing the efficiency of the cells that allows for smaller, cheaper systems and that allows for better access to purchase solar cells or solar panels depending on different incomes as well as the physical installations.

A solar power module is referred to as a “solar panel” and it is a collective number of solar cells, different types and different sizes can produce 50 to 220 watts of electricity.

Major manufactures like Sunpower, Powerlight, Sharp and others build modules with a life expectancy of 25 to 30 years.   If your thinking about installing a Solar Power System, then that would be a good reliable investment.
