1. What is the load?
Identify the pump, motor, heater, controller, valve, charger, or equipment panel that actually uses electricity.

A solar water system is not just one thing. It can mean solar-powered pumps, pool equipment, pressure tanks, well pumps, livestock water, stored-water pumping, battery backup, or a smarter way to manage the electric loads that make water move.
The Solar Plumber view
Most people think of water systems as pipes, valves, fixtures, tanks, drains, heaters, and pressure. The solar conversation begins when the system needs electricity: a pump starts, a controller wakes up, a pool schedule runs, a pressure tank calls for refill, or a battery is asked to keep something alive during a blackout.
TheSolarPlumber.com focuses on that meeting point. ABC Solar is not trying to become the plumber. The goal is to understand the electrical side of water movement so solar and batteries can be designed around real loads instead of guesses.
Start with the load
Solar design gets better when the water system is broken into loads, schedules, priorities, and failure modes. A pump that runs at noon is different from a pump that must start at midnight during a blackout.

Runtime matters. A pool pump running during peak utility hours is a different problem than a transfer pump running occasionally.
Some water loads are convenience loads. Others protect health, animals, property, food, cooling, or basic household function.
Solar and batteries are not magic
Solar can provide energy. Batteries can provide stored electricity. Neither one fixes a failing pump, bad pipe design, poor water quality, unsafe wiring, gas-appliance risk, missing permits, or an undersized pressure system.
A good project respects the trades. The plumber handles plumbing. The electrician handles electrical work. Pool, well, gas, fire, and structural specialists handle their scopes. Solar planning should help coordinate the load, not blur the licensing lines.
Common solar-water categories
Pool pumps can run for long hours. In expensive utility territory, the schedule and energy source matter.
Pool equipment and solar
A well pump may need startup surge, storage strategy, and careful backup planning if the property depends on it.
Well pumps and solar
Pressure tanks can reduce pump cycling and help define what backup power must actually accomplish.
Pressure tanks and solarBlackout readiness
Backup design is about priorities. A refrigerator, medical device, internet equipment, lighting, garage access, and selected water loads may compete for the same stored energy. The water system must be ranked honestly.
The Solar Plumber approach separates essential water function from normal comfort. A ranch may prioritize livestock water. A home on a well may prioritize basic water pressure. A pool owner may only need limited circulation. A fire-readiness concept may require a separate, professionally designed approach.
Solar hot water vs solar electric
Pumping water is usually a motor-load question. Heating water is an energy-conversion question. Both can be part of a solar discussion, but they should not be treated as the same design problem.
| Topic | Moving Water | Heating Water |
|---|---|---|
| Main device | Pump, motor, controller, pressure switch | Water heater, heat pump water heater, resistance element, thermal system |
| Key concern | Startup surge, runtime, gallons moved, pressure | Daily energy use, recovery time, tank size, fuel type |
| Solar approach | PV, inverter capacity, battery backup, load scheduling | PV offset, load shifting, possible thermal concepts, storage strategy |
| Risk | Undersized backup, failed pump start, poor controls | Slow recovery, high electric load, gas/electrical code issues |
Manga field lesson
The pump says, “I need power now.” The tank says, “I bought you time.” The battery says, “Do not waste me.” Solar Sensei says, “First we make a load schedule.”
The pump is the muscle. It may need more startup power than the homeowner expects.
Storage can change the problem. Water stored at the right time may reduce the need for emergency pumping.
Battery power should be reserved for loads that matter, not wasted because no one made a plan.
TheSolarPlumber.com is educational only. It is not plumbing advice, not electrical engineering advice, not gas-appliance advice, not pool-code advice, not well-system advice, and not fire-safety design. Pumps, batteries, water heaters, wells, pools, pressure tanks, gas appliances, fire-safety systems, and backup-power systems require proper design, permits, inspections, and licensed professionals.
ABC Solar Incorporated
ABC Solar can review solar, battery, and electrical-load planning for water-related equipment and help define what belongs in the solar scope before the project gets messy.
