The renewable heating and solar specialists.

Renewable Heating and Solar Specialists since 1991.

Llani Solar and Biomass Ltd are based in Llanidloes, Powys, and are independent installers of renewable energy technologies in Mid Wales. We design, supply and fit unique high quality solar hot water, solar electric, and wood fuel heating systems, including Biomass and log burners, in Wales and its borders, constructed to fit your individual requirements.

These modern, efficient and green energy technologies are beneficial to your domestic or commercial property, your wallet and your carbon footprint. They can help to reduce your energy costs and energy usage, whilst our Microgeneration Certification Scheme (MCS) accreditations allow our customers with eligible systems to claim the Renewable Heat Incentive (RHI), or the Feed In Tariff (FIT), earning you an income as you save energy. (See for more information on the RHI and FIT payments.)

What we can do for you

As independent installers of renewable technologies in Mid Wales, Llani Solar and Biomass Ltd will design, install and maintain a green energy system that is specifically constructed to fit your home or business, your budget and your energy requirements. We have no tie to any one supplier, and therefore are dedicated to providing each of our customers with the best product for their needs. From start until finish, we provide a friendly, professional service.

Our personalised installations are suitable for anything from a small cottage to a large holiday home complex, and anything in between.
