When Solar Water Heating Makes Sense and How It Fits

We first isolate the thermal load causing high bills, then show how a dedicated water-heating system reduces electrical demand and improves Solar PV economics.

THE THERMAL DRAIN

Why Your Bill is High

Heating water using electricity is thermodynamically inefficient. A single instant shower can draw as much power as 50 LED bulbs, making it the primary driver of high utility bills in Kenya.

  • Converting electricity to heat at point-of-use is inherently wasteful
  • Instant showers can draw 3-5kW continuously, draining batteries fast
  • Sun's direct radiation heats water for free, stored in insulated tanks
High-efficiency SWH System
THE ECOSYSTEM ADVANTAGE

Pairing with Solar PV

Running instant showers on batteries pushes Solar PV systems into oversized inverter and battery requirements. A dedicated solar water-heating system usually solves the thermal load more efficiently.

  • Dedicated SWH removes the largest thermal load from your battery
  • Reduces required Solar PV system size by up to 40%
  • Lower PV system cost means faster payback period overall

Engineering Standards for This Service

We match collector type to plumbing pressure, climate conditions, and reliability requirements. Definitions and comparisons are linked in Resources.

Flat Plate (Pressurized)

The standard for modern residences with pressurized plumbing. Features high-strength tempered glass and aluminum-copper absorber plates for maximum durability in all weather conditions.

Evacuated Tubes (High Efficiency)

Ideal for areas with frequent cloud cover or high altitude. The vacuum-insulated tubes provide superior heat retention, ensuring hot water even in overcast conditions.

Process & Deliverables

This is the Solar Water Heating delivery summary for this service. The full cross-service workflow is on the How We Work page.

How We Deliver Solar Water Heating

SWH-specific selection and integration checkpoints from demand review to handover.

01

Demand & Site Review

We assess household/business usage, roof position, plumbing layout, and pressure type.

02

System Selection

Flat plate vs evacuated tube is selected based on performance and durability needs.

03

Install & Integrate

Collector, tank, valves, and any required electrical/plumbing integration are completed.

04

Test & Handover

Pressure checks, temperature performance checks, and user handover guidance are provided.
