PV nameplate rating is a peak condition, not an energy total.
SOLVARN · ENERGY PLANNING
How much energy can a solar pergola produce?
The honest answer is an energy range based on entered solar-resource assumptions—not a guaranteed daily number.
SHORT ANSWER
Use peak-sun-hours and a derating factor to create an illustrative daily energy balance.
Multiply installed PV kW by the project's entered peak-sun-hours and a transparent derating factor, then compare that illustrative yield with daily loads and battery reserve. Re-run for seasonal or worst-case conditions.
KEY PROJECT POINTS
What should drive the decision.
These are project inputs, not substitute engineering or automatic product approvals.
Peak-sun-hours vary by location and season.
Heat, dust and shading reduce output.
Battery charging/discharging and inverter losses matter.
Energy surplus on an average day does not prove off-grid autonomy.
Seasonal scenarios are more useful than one headline estimate.
Start from installed PV kW
SOLVARN's nominal array power is the first input, but it needs solar resource and losses to become an energy estimate.
Enter solar resource explicitly
Peak-sun-hours should come from a suitable project/location source. Apollo should not hide one global default inside the tool.
Use a transparent derating factor
A planning derate can represent module temperature, inverter/conversion losses, wiring, soiling and other real-world effects.
Compare yield with loads and reserve
The useful output is daily balance and battery-only planning duration—not a claim of guaranteed autonomy.
PROJECT INPUTS
What to have ready before asking for the exact system.
A stronger brief shortens the gap between product interest and a useful technical/commercial response.

EVIDENCE BOUNDARY
Energy estimates are planning outputs, not performance guarantees.
Use exact PV/inverter/battery documentation and project-entered solar-resource assumptions. Final energy performance depends on installation, orientation, climate, shading, maintenance and actual load behaviour.
FAQ
Questions project teams usually need answered.
What is peak-sun-hours?
It is a way to express daily solar irradiation as the equivalent number of hours at 1 kW/m².
Why use a derating factor?
It represents real-world losses so the estimate is not simply nameplate power multiplied by sun hours.
Can the tool guarantee daily solar output?
No. It is a concept planner based on entered assumptions.
