Solar PV Calculator.
Sizes a solar PV array — panels, array size (kWp), indicative generation — from roof area, orientation and location. The registered calculation provides an indicative array and generation estimate from explicit regional yield and system-loss inputs; it does not recommend panels or inverters.

From project input to reviewed output.
The page explains the workflow, identifies the information required and routes the user into Adelphos for the complete task.
Adelphos workflow
Provide the brief and source information, confirm the required output, run the applicable named tools, then review the result and resolve assumptions before use.
The user is responsible for verifying all inputs, assumptions, standards, selections, outputs and suitability, and for obtaining competent-person review. Adelphos accepts no responsibility for decisions made using this calculation.
Frequently asked questions.
How many solar panels do i need?
Panel count depends on usable roof area, panel rating, orientation, pitch, shading, regional yield, system losses and the design objective. The calculator produces an indicative array from explicit inputs and does not recommend a panel or inverter.
What size pv system for my roof?
Measure the genuinely usable roof area and enter the proposed panel dimensions and rating, then apply sourced orientation, regional-yield and loss assumptions. Structural capacity, access, fire safety, network and electrical design remain separate checks.

How do I use Solar PV Calculator?
Open Adelphos Chat with the project brief and relevant source files. Adelphos will identify the required inputs, run the applicable workflow and present the output for review.
Can an AI agent use this through MCP?
Where the workflow exposes a named MCP tool, an authorised agent can submit the structured inputs and receive the same traceable result. Consequential outputs remain subject to user review.
