Last I checked, rooftop solar in the US costs about $2.5-$3.5 per W – $2.5/W if it is a commercial rooftop and $3.5 if it is residential. For Australia, a Cleantechnical report states that the corresponding figures are $1.6-$1.76/W, which also states that…
California Farmers Shifting to Solar Energy Crop?
California is a well-known solar energy hub. But we all would have thought that was because it gets lots of sunshine. Looks like there is another reason – large parts of California does not get enough water. Here’s an interesting…
Solar Cell and Panel Efficiency
Summary: Conventional solar PV cell efficiency are in the range 10-22%, and module efficiency in the range 9-20%. If only we had super high efficient solar cells, the whole world would only be using solar to power everything. So what…
Solar Tracker – Tracking the Sun for Maximum Power
Summary: Solar trackers enable to keep the solar panels normal to the incident sunlight, and hence enhance electricity generation significantly Did you know that by changing the angle of solar panels frequently, you could generate much more electricity from the…
