MAPPS® Remote Industrial Solar System Design Tool

This tool helps you find the right MAPPS® solar system in 3 easy steps!

Start by estimating your daily energy use with our MAPPS Load Calculator, entering every continuous or intermittent load and averaging any day-to-day swings. Next, pinpoint your location by clicking the "Solar Irradiance Map" link in step 2 to view the winter irradiance map and identify your specific zone. Once you have the watt-hours per day and your solar zone, enter them below alongside your desired system voltage to find the best MAPPS® system for your needs. Need help? Reach out to us at Contact@SolarElectricSupply.com for assistance related to MAPPS®.

1. Enter your Daily Power Requirement (Watt-hr/day)

Begin by listing every device you’ll power in the MAPPS® Load Calculator below – it adds up the Watt-hours for you in real time. For an ofline copy, download the excel worksheet.

2. Select your Solar Zone

Locate your site on the Solar Irradiance Map (click to view) . The values represent average winter insolation; energy availability increases from Zone 1 to Zone 5.

3. Select System Load Voltage

Pick a system voltage, then compare the table values for your zone to your required Watt-hours. Select the MAPPS model that meets or exceeds your need.

MAPPS® Watt-hr/day Load Calculator

Qty Load Description Amps Volts Watts Hours/day Watt‑hr/day
Total Watt‑hr/day: 0.00

* Example: Calculating Watt‑hours for a 25% duty‑cycle radio

Qty Load Description Amps Volts Watts Hours/day Watt‑hr/day
1 Radio Transmit 3 12 36 6 72
1 Radio Standby 0.5 12 6 18 108
Total Watt‑hr/day 324

* Use the actual operating current and duty‑cycle for each device to calculate daily Watt‑hours. Spec‑sheet ratings often show peak currents that are higher than average consumption. We recommend bench‑testing your equipment under expected field conditions for at least 24 hours before selecting a MAPPS® system.

MAPPS® Solar Power System Performance Tables

The tables below represent the Watt-hours per day performance of each MAPPS system in the different solar zones. Choose your system voltage, then look down your solar zone column for the value that meets or exceeds your design load Watt-hours. Follow the row to the left for the corresponding prepackaged MAPPS system that will fully power your load requirements. Complimentary solar sizing analysis for your location can be provided with quotation.
