10kWp PV array, Cornwall

Modelling system with PVSol to advise on system selection.  The modelling enabled the client to select the solar modules which provided the greatest energy output for the lowest price in a setting where space was not an issue. The modelled specific energy output 915kWh/year/kWp, which is the best we have seen. 




Energy Assessor

I am delighted to say I have just passed my exam for on Construction Domestic Energy Assessor.  I will get the full accreditation next week having attended a course in January, submitted a portfolio including energy assessment for 5 dwellings and completing an interview.  It's taken 4 months to get the qualification and is reasonably demanding - around 100 hrs.  

I am now qualified to produce Energy Performance Certificates for new houses.  What next?  Passivhaus or Green Deal?
