- | The cost of higher efficiency panels typically outstrips the increase power, so unless you are tight for space they typically aren't a good value for money. | + | The cost of higher efficiency panels typically outstrips the increase power, so unless you are tight for space they typically aren't a good value for money. |
- | > At zenith, sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level. Of this energy, 527 watts is infrared radiation, **445 watts is visible light**, and 32 watts is ultraviolet radiation. -- [[https:// | ||
- | Mono panels can capture about 15-20% of this visible light energy. | ||
