I was hoping you could help with a general question. Can you tell me how the average price of residential PV systems in Japan has changed in 2011 and early 2012? Is there a resource that tracks the changes in quarterly average installed costs? Has the JPEA considered tracking this information and providing it as a benchmarking resource for the public?
Thank you for your contacting us, but so sorry too late reply to you.
Regarding your question of average residential PV system price. This organization; JPEA hesitates to announce PV system price. Because it might conflict with the Antitrust Law, therefore JPEA is not able to show the PV system price.But we could get average residential PV system price information from Home-Page of JPEC (Japan Photovoltaic Expansion Center).
The Data of actual result are shown as below. We are not able to get the data of 2012 yet.
Case1 :Installation to New House.
Case2: Installation to Existing House
Thank you so much for this information. I believe it is important for the PV industry in Japan to keep track of installation statistics and regularly provide updates to the public. This gives the commercial and business sectors a reliable source of information to cross-check when they go to buy a system. This cross-check reduces over-charging and spurs healthy competition.
Transparent and reliable statistics also provide government administrators with a benchmark for adjusting the FiT in the future - a benchmark they can be publicly held accountable to when it comes time to adjust FiT rates next year. I have seen very few countries reliably track installation costs and volumes. It is something I humbly suggest the JPEA should think seriously about. If this is against the JPEA's charter maybe the JPEA can encourage a 3rd party to gather and broadcast the information.
Thank you for your comments.
Especially cross-checking and updating of data is very important for consumer & contractor to reduce over-charging and to spur health competition.
And also disclosure of PV system installation price contributes to the healthy development and fixation of the FIT system in Japan.
