Solar Panels For Homes

I want to install a PV solar unit on our house. But with technology changing in this field.Does it make sense?

If I install a PV system today, that has an effeciency rating of 17%
and lets assume that every two years technology will net a 2% increase in efficiency. Does it make sense to get in the game now? Are there any PV systems manufacturers/installers that will replace the old panels with new more efficient ones 5-7 years down the line?

I doubt you will find any manufacturer that will do a swap after 5 years of use.

You have to calculate the numbers. Cost and savings now, versus costs in 5 years. Will todays design pay for itself in the next 30 years? How about the design of 5 years from now. Will it pay for itself, plus the loses for those 5 years?
