Solar Powered Irrigation

Our solar powered irrigation system makes off-grid watering simple and reliable. Designed for allotments, gardens, greenhouses and remote plots, WaterMate uses smart sensors and solar energy to keep plants perfectly watered with minimal effort.

Why Solar Powered Irrigation is Beneficial for All Setups

Reliable watering is one of the biggest challenges for growers without mains power. Whether you’re watering an allotment, a vegetable garden, a greenhouse, or a remote plot, keeping your plants hydrated can become back-breaking and time-consuming.

A solar powered irrigation system helps you maintain a consistent watering schedule by turning sunlight into energy for this task, making it ideal for off-grid or eco-friendly growing. With no need for mains power or constant supervision, your plants will stay healthy even when you’re away.

WaterMate takes this a step further. Its smart, sensor-based system responds to real-time weather conditions, delivering just the right amount of water, exactly when needed.

It’s a reliable solar irrigation system that keeps your crops thriving all year, powered purely by the sun.

  • Up to 80% Less Water Used

  • Targeted Watering = Zero Waste

  • Reduces Runoff and Overwatering

How Solar Powered Irrigation Systems Work

The compact solar panel in our WaterMate bundle converts sunlight into power and stores it to keep the watering system active even at night or on cloudy days. Temperature and humidity sensors track real-time conditions, adjusting watering automatically as the weather changes.

Once set up, WaterMate runs quietly in the background. You can pause or adjust your watering schedules through the Harvst web app for complete control whenever you need it.

Designed for off-grid use, the system connects easily to water butts or tanks and adapts to various types of gardening setups. It’s a reliable solar irrigation system that keeps your plants healthy through every season.

Challenges That a Solar Powered Irrigation System Solves

Eliminates reliance on mains electricity: With solar power, your watering system runs independently, even in gardens or allotments with no access to the grid.

Keeps watering consistent: Our watering system stores solar energy to run automatically, so your plants will never dry out when you’re away or when the weather suddenly changes.

Reduces water waste through precision control: Smart sensors deliver exactly the right amount of water to the roots, cutting down on runoff and preventing overwatering.

Protects plants from environmental stress: Automated scheduling maintains steady soil moisture, helping prevent wilting and uneven growth across your beds or greenhouse.

The Benefits of a Solar Powered Irrigation System

Switching to solar powered irrigation simplifies your gardening duties and helps you maintain sustainable watering for your plants.

Manual watering can be unpredictable, especially in remote or off-grid areas. However, with a solar powered irrigation system like WaterMate, your plants will receive the precise amount of water they need, when they need it, without relying on mains electricity.

Beyond ease of use, our solar irrigation solution also improves overall plant health. By keeping watering consistent through changing weather, it prevents dryness and overwatering that can weaken your plants.

As a result, your plants grow bigger, stronger and more evenly. Plus, you get more freedom and time to spend away from the mundane gardening jobs, like watering. This offers peace of mind for gardeners who want a consistent solution through every season - even during holidays or dry weather.
