// LESSONS FROM EfficiencyOne
Position solar as the final sustainability step after a tight building envelope, not a substitute for insulation and good windows.
Early in a new technology market, you must sell the category itself, not just your company; client education is the first job.
Adoption tips when efficiency, trust, and cost mature together; watch the heat-pump curve as a template for where solar is headed.
Standing-seam metal roofs are ideal because clamps fasten to the seams with zero penetrations; have a solution ready for every roof type.
Sell on lifecycle economics: solar's 25-year warranties and no moving parts beat alternatives like wind turbines warrantied for only three years.
In a politically charged market, a single regulatory change can wipe out your business; treat policy risk as core operating risk.
