We provide design work including performance characteristics, layout designs and electrical connection schematics for solar PV arrays for systems from 50kW to 10MW. We also fully project manage the procurement and installation phases through to commissioning.


The term Biomass indicates the fuel being burnt comes from animal or vegetable matter. In comparison to fossil fuels greenhouse gases can be reduced considerably. Biomass fuel can used for heat and power production or a combination of the two. Contact us today for a biomass survey.

Energy Management Systems

Improving how you use the power from an onsite generator is often overlooked and can save you money on your energy bills. Exporting power to the grid, in favour of supplying onsite needs, can mean you are not getting the maximum potential benefits from your system. SJ1 Renewables can provide site specific energy management systems which ensure your needs are put first. We design the perfect intelligent energy management system that maximises revenue and optimises system performance. Get in touch today for a free appraisal of your sites potential.

With our partner organisation Kernow Controls Ltd, we have designed a fully automated energy management system that communicates with your electrical power generator and the onsite electrical loads. These work with a wide range of applications and technologies such as wind turbines, solar PV, Heat pumps for both grid-connected and off grid systems.
