Solar power: a promising renewable energy source
Posted by Solar energy guru | Filed under Solar energy facts
The two main types of solar renewable energy are electricity and heat. Solar cells use the photoelectric effect to convert sunlight directly into electricity. Solar collectors absorb sunlight and use its thermal energy to heat a fluid. There are many advantages to using solar renewable energy, including its free and limitless supply, but also a [...]
Solar panel efficiency
Posted by Solar energy guru | Filed under Solar energy facts
One thing that people who scoff at solar power like to point out is that solar panel efficiency averages only 20%. What that means is that most photovoltaic (PV) panels convert only about 20% of the captured solar energy to electricity. Even the most advanced designs using silicon are only able to operate at around [...]
