FAQs
Are there any limits to the eligibility of solar thermal systems?
Yes sadly - solar hot water systems are only eligible up to 200kWth.
The tariff levels are also proportionately lower than other heat technologies.
Only water heating panels (flat plate and evacuated tube) are eligible; transpired collectors are not.
Chapter 4 of the government's RHI announcement says
Solar thermal
Solar thermal panels (liquid filled flat plate or evacuated tube solar collectors) will be eligible for support. Solar thermal installations will be eligible below 200kWth capacity only.
Additional solar thermal capacity added to an existing installation, bringing the total capacity above the tariff threshold of 200kWth, will not be eligible for the RHI. We will consider introducing support for solar installations above this scale from 2012.
