SOLAR EPC PROJECT PATH
From energy brief to a bankable solar package.
For homes, factories, commercial roofs and remote sites, we organize the first-pass assumptions before detailed design, local permitting and final supplier confirmation.
Match the equipment package
PV modules, inverter topology, battery chemistry, protection, mounting, monitoring and grid interface.
Issue a comparable RFQ
Compare technical deviations, delivery scope, inspection documents, warranty boundaries and export terms.
PROJECT TOOLS / PRELIMINARY ONLY
Basic solar project calculators
Use these for early conversations only. They do not replace a site survey, shading study, structural review, local code check or final electrical design.

Questions to answer before requesting a solar quote.
Should the project be on-grid, off-grid or hybrid?
Start with grid availability, critical-load requirements, generator interface and whether the priority is energy savings, backup or energy autonomy. The final topology depends on the site study and local approval requirements.
What information is needed for a preliminary RFQ?
Share the country, site type, daily energy use, peak demand, operating hours, available roof or land area, grid voltage and frequency, backup hours, drawings or photos, and the requested delivery scope.
Can BuJuan provide a complete EPC contract?
BuJuan coordinates the project brief, engineering resources, supplier comparison and export supply. Final design, local permits, construction supervision and statutory sign-off are assigned to the responsible project parties in the written scope and contract.
What does a battery storage package need to define?
Define usable energy, power rating, duration, round-trip expectations, battery chemistry, ambient conditions, fire and safety requirements, inverter interface, monitoring and warranty boundaries.
Set the technical basis
before comparing supply.
Clear inputs help suppliers quote the same requirement. Final product selection and compliance depend on your project documents and the selected model.
