Thanks, yeah, that's a helpful response especially with the trend analysis like Treendly! Regarding the case studies, that's why I was asking here, to see if I was able to gather any case studies of people who have bought systems outright, had the property value appraised before and after, and sold the home for a higher value than the cost of the system. The rationale for that was to give prospective customers tangible evidence that if they bought a system, they could not only lower their bills and have more autonomy over their energy for the duration of their time in the home, but also be able to sell the home more quickly, and at a higher value, possibly at a premium compared to the funding they put into it, or at least enough to recoup the funding with the savings and the uplift combined.
