A server-side proxy avoids browser security blocks. Endpoint should accept ?lat=&lon= and return PVGIS JSON.

System Loss (%)
?
Total solar system losses (soiling, wiring, temperature) fed to PVGIS. Default 18% for Chad. PVGIS already models temperature, so values above ~22% over-derate the yield.

🔋 Batteries on site
Battery type
?
The battery model and capacity. 200Ah units store more per unit; 100Ah are smaller. All are 48V wired in parallel.

Existing batteries on site
Optimization Goal
?
How to balance build cost vs running cost. Balanced = lowest total cost over asset life. Min GE Runtime = more solar/battery to cut fuel. Min CAPEX = leaner build, generator runs more.

Min CAPEX
Balanced: reasonable solar + battery, GE as backup.
Site Access
?
How easy the site is to reach. Affects battery backup sizing — harder-to-reach sites get more autonomy so technicians visit less often.
Unrestricted Access
Restricted Opening Hours
Seasonal Access
Remote / Rarely Accessible
Inaccessible months
Reason (optional)
Load Parameters
Avg. Survey Load (kW)
?
The load estimated during the site survey. Used for sizing only if no RMS measurement is available.
Avg. RMS Load (kW)
?
The measured average load after the site is cut over to the new system. This is the PRIMARY sizing driver — it overrides survey and client estimates when available.

Solar Space (m²)
?
Available area for solar panels. Limits the array size. Tick "Unlimited" for sites with no space constraint (e.g. ground-mount with open land).
*
Unlimited space
Site Area (m²)
Technician Base (city/coords)
Round Trip (km)
?
Distance for a technician round-trip from base to site. Drives maintenance trip costs and influences battery backup sizing. Use "Calc" to compute from coordinates.

Emergency Backup (hrs)
?
Minimum hours the batteries must power the site with no solar or generator — a hard floor for critical backup.

Monthly Revenue (USD)
?
The fixed monthly fee the operator pays you for this site. Drives the ROI, payback, and EBITDA calculations.
Min. EBITDA (USD)
?
Optional target for monthly operating profit (revenue − running cost). The tool flags whether the configuration meets it — it does not change the build.
Target Payback (mo)
?
Optional. The number of months you want to recover the build cost. Works with "Auto-optimize" below.
Auto-optimize config
?
When ticked with a target payback, the tool searches configurations to find the cheapest one that hits your payback goal — without dropping below safe reliability limits.
Planning Horizon (years)
?
How many years to count running costs (fuel) when deciding the optimal mix of solar, battery, and generator. This is the expected service life of the system at this site — NOT a payback goal. A longer horizon justifies more solar (it has more years to save fuel); a shorter one favours a leaner build. Default 5 years.
