Hi,

I am looking for information on embodied carbon for solar renewable energy systems to evaluate in context of the offset fossil fuels through those systems. For PV I have found some info here:

Does anybody have embodied carbon info on solar hot water system?  
Are there EPDs for those types of systems?

Thanks,  
Jens

There is some data for Solar Water Heaters in OneClickLCA:  
0.0015 kg CO2e per Liter hot water produced  
0.0203 kg Co2e per kWh hot water produced

Hi Jens,

I have been doing some similar thinking on the steel, concrete, and aluminum heavy transmission infrastructure needed to accommodate more renewables and electrification. See two reports on T&D lifecycle analysis and [one](https://wiresgroup.com/wp-content/uploads/2019/03/Electrification_BrattleReport_WIRES_FINAL_03062019.pdf) on the level of T investment needed. Can we offset some of that with lower embodied carbon EE in buildings? I think so.

Just added tag to this as PV and Solar. Search for earlier posting on Solar to see a report on the topic.

Hello,

I have some papers that might be helpful if you like? They mostly look at the LCA of solar water heaters.

Hi Ruth, I am very interested in LCA of solar hot water, it would be great if you could point out to me how I can access… Thank you, Jens

Hopefully you can get the papers from these. The focus is mainly on domestic water heating but they’re not US studies.
