Hi Robert,
Capital Allowances whether these are claimed within the Annual Investment Allowance (AIA) or not can't be claimed as a tax deduction form income derived from residential rental businesses; with the exception of income from holiday lets that meet certain conditons. But you are correct that the costs of alternative energy systems such as solar pannels will usually qualify for a tax deduction under the AIA rules. The current AIA limit is £100,000 but this is due to fall to £25,000 from April next year. However there are transitional rules which mean that the reduction can affect businesses in an accounting period straddinlg that date. Essentially the current £100,000 limit will be pro rated on a time basis to the period prior falling before April 2012.
I don't understand the second part of your query but if you are asking whether AIA/capital allowances can be claimed as a deduction against rental profits from resdiential accomadation or only against trading businesses, then I think I've answered your question in my comments above.
