Screen solar potential
Early photovoltaic production and financial screening with explicit editable assumptions; not a bankable design.
Solar production and simple-payback screening
The workflow estimates annual output and cash-flow indicators from user-supplied system, yield, tariff, self-use, export, operating-cost and carbon assumptions. It is an early screen, not an engineering design, financing model or bankability assessment.
Key capabilities
Use a documented annual specific-yield assumption for the site.
Show installed cost, tariff, export value, self-consumption, O&M and degradation.
Calculate annual benefit, simple payback and undiscounted lifetime return.
Enter a dated grid factor rather than relying on a universal default.
Use cases
- Early rooftop screen
Test whether a site merits a detailed survey and load-profile study.
- Assumption review
Compare tariff, self-use and yield inputs before specialist analysis.
Frequently asked questions
Does this calculate IRR?
No. It reports simple payback and undiscounted return.
Are tariffs and carbon factors supplied?
They are editable assumptions that must be dated and verified for the selected country.
Does it model shading or batteries?
No. Interval loads, shading, grid constraints, tax, financing and storage are outside this public calculation.
