A household energy project should be assessed for the property it will serve. Begin with the site, the way energy is used and the practical constraints before comparing equipment packages.
A practical example
For a solar proposal, ask the supplier to explain the roof assumptions, the household information used and the work included in the installation. If storage is proposed, clarify the separate purpose it serves. Have qualified professionals assess installation and connection requirements.
What to check
- Give suppliers the same property and energy-use information.
- Ask for assumptions, exclusions and ongoing responsibilities in writing.
- Separate technical estimates from commercial assumptions about future costs.
The trade-off
A proposal may be useful without predicting the household’s future precisely. Compare like-for-like assumptions and ask which uncertainties would materially change the recommendation.
Research context
US Department of Energy resources describe planning considerations for residential solar. They provide general context; local installation, connection and commercial arrangements require a qualified site-specific assessment.
