The figure, cited in a report
from Lawrence Berkeley National Laboratory, coincides with Clean NRG Perth‘s
calculations. For example, in 2010 a 5kW system would cost in the vicinity of $20,000. Now, the market price for a 5kW system with better, more efficient technology is under $7,000! However with the Australian dollar falling, we don’t know how long this will last.
“It is incredibly exciting to see this amount of growth in the solar Industry!” says Craig Donohue, Managing Director of Clean NRG. “We are passionate and determined to help W.A.’s households and businesses significantly reduce rising electricity bills.”
To date almost over 15% of Perth homes have installed solar. Not bad for an industry with no large-scale presence within Australia just a decade ago. Solar panels
currently contribute only less than 5% of W.A.’s electrical generation capacity, but lower solar costs are helping with the expansion of large scale projects, with only around 1% of businesses installing solar. Considering businesses pay more for their power and use power during the day the return on investment is even better. The money businesses save by installing solar can pay for the system in less than 4 years, so you either pay the electricity company for the rest of life or install Solar.
