Guides
These guides exist because most solar products fail for predictable reasons — undersized arrays, wrong battery chemistry, and specifications copied between markets. Each guide gives you numbers you can check.
A practical specification guide for solar street lights: autonomy, battery chemistry, luminous flux, derating and road-class sizing tables for importers and project engineers.
Learn to size an off-grid solar system step by step: load audit, battery bank, depth of discharge, array sizing and inverter selection, with a full worked example and tables.
How to select a solar irrigation pump: calculating total head, matching flow to crop area, sizing the solar array, and comparing running cost against diesel pumping.
Tell us the destination country, target quantity and what the product must do. We come back with a model, a price and the lead time.
