Solar Power Systems Cost
When will solar Power systems be cost effective enough to ‘pay for itself’ within a few years?
Solar Power systems are inherently expensive, and even living in a hot sunny climate, It will take over 20 years for the cost of the system to have paid itself off in terms of reduced power bills…
Technology is always evolving, getting more efficient, cheaper, smaller, more powerful … what are the next steps for home use solar power generation? and when will a system be cheap enough to buy that it will have been ‘paid off within a few years’ (not 20)
I heard that using photosynthesis processes from plants can be combined into an electricity generating paint, more efficient than silicon cells now, whens this coming out? what other technologies are there?
solar heating systems, like all water based energy systems are not very efficient. but the cost is reasonable.
solar to electrical the price is due to the energy conversion, just recently the 35 – 40% mark was broken. that means that 35 -40% of the solar energy is converted in electricity. but also means that 60 -65% is not converted and is unusable. labs around the world are working on solutions to increase the usable percentage. the big problem is that to get higher percentages more and more man made chemicals are needed. there by increasing the cost. that is not including the money that is needed to regain from the research and development stages. but once a system can be massed produced and if a majority will buy it then the price will drop. supply and demand.
