What we're building

This is the product direction, written the way a customer would say it. The backlog builds up to this page by page: the lists and pages come first, and the calculations come online as the team learns them. If a story serves none of what is written here, question it.

piDSS: know before you go solar

piDSS is the independent solar decision tool for Barbados businesses. It answers one question honestly: should my business go solar, what exactly would it cost, and will it pay for itself? piDSS does not sell panels. It brings together real local equipment prices, installer and technician fees, utility tariffs, tax rules and financing, then shows each business owner what solar would mean for their buildings, including when the answer is “not yet” or “not like that”.

A business owner records each building they operate: every appliance and machine they run, any solar equipment they already own, and the panel mounting area they have available (a roof, carport, ground plot or wall). From that, piDSS rebuilds their current electricity bill from the published tariff, sizes the solar system their building actually needs, and shows the honest whole-life cost: hardware compared across suppliers, plus surveys, installation labour, physical security, maintenance, insurance and replacement reserves. Then the verdict: yearly savings, years to payback, and a clear warning when a system will never pay for itself.

When the numbers look good, the owner saves a dated Decision Dossier, a printable report that never changes afterwards, and sends it to the installers they choose. Rates and prices all live in the data with their as-of dates, so when the power company changes its numbers somebody edits the data, not the code.

How it works, step by step

  1. Learn: read the Barbados solar industry prelude, or try the Solar Offset Calculator without an account.
  2. Model your business: add your sites, electronic equipment records, existing solar and panel mounting area.
  3. Get honest answers: savings estimate, battery verdict, true total cost of ownership, tax savings, financing, payback and the three-way scenario comparison.
  4. Check anything: open Show the Math on any figure to see the formula, the rate used and its source.
  5. Act on it: save the Decision Dossier, book a certified survey, and request installer quotes.
