A large number of developers are currently specifying the RM Solar system as a means to achieve the necessary Target Emission Rates (TER). Whilst the use of Solar Thermal improves the Dwelling Emission Rate (DER), many developers have expressed that quality, performance and cost are key factors in their selection process. In addition, kerbside appeal of the finished dwelling is paramount. At RM Solar we have successfully combined all of these elements without compromise.
 
At RM Solar we believe that the achievement of targets only addresses a small part of the long term solutions, and that is why our panels carry a full 20 Year warranty. This guarantee covers both durability and performance. All of our panels carry full EN 12975 Part 1 & Part 2 certification, and have a life expectancy of 35 Years+. We believe that this is a very important factor when choosing a product of this nature, the longer it lasts the more the homeowner saves.
 
Long term life makes it particularly suited for Housing Associations and Registered Social Landlords. Owing to the long term guarantee and expected life, amortised ownership costs remain very low, particularly when combined with low capital costs.
