A dated solar decision dossier with named owner and acceptance criteria, source-linked site and tariff inputs, comparable production and cash scenarios, unresolved risks, written proposal evidence, authorization records, and a measured follow-up plan.
Go Solar
Build a source-led home-solar decision dossier from bills, site evidence, production scenarios, written proposals, current incentives, contracts, commissioning, and measured results.
- • Name the decision owner, technical/tax reviewers, and final acceptance authority
- • Attach or reference at least 12 consecutive months of meter and bill evidence
- • Link the current tariff, fixed/minimum charges, time periods, and export-compensation rule
- • Record planned load additions, removals, efficiency work, and ownership horizon
- • A blended $/kWh average can hide fixed charges, demand charges, time-of-use periods, minimum bills, and different export compensation.
- • A past load profile can become obsolete after an EV, heat pump, household, work-from-home, efficiency, or occupancy change.
- • Latitude or tilt alone cannot determine production, suitability, structural capacity, fire access, waterproofing, permitting, or interconnection.
- • Tree growth, seasonal shadows, roof replacement, service upgrades, access requirements, and local restrictions can change the feasible design.
Choose your path
Built around the job you need to finish
Carry one residential solar question from bills and site evidence through reproducible production/cash scenarios, comparable written proposals, qualified authorization, commissioning, accessible handoff and measured acceptance.
Owner deciding whether to buy rooftop solar
Keep bills, roof facts, proposals, current incentives and decision criteria in one reviewable record.
Complete the six evidence gates and authorize only after unresolved site, tariff, contract and authority issues have owners.
Ends with a dated decision dossier rather than an automated yes/no verdict.
Technical, tax or contract reviewer
Trace every consequential number and claimed requirement to a current source or entered assumption.
Audit site-model versions, tariffs, official incentive eligibility, written scope, licenses, permits, interconnection and contracts.
Can reproduce comparisons and block approval when evidence or authority is missing.
Owner who needs accessible operation and handoff
Receive readable instructions, emergency routes, monitoring/data access and clear ownership after installation.
Record accommodations before authorization and verify them during commissioning and acceptance.
Can operate, monitor, export data, escalate issues and transfer the record without relying on one inaccessible portal.
Authoritative checks for this workflow
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
