Step-by-Step DIY Guide: Building Your Solar Water Feature

Ready to create your own solar-powered water feature? Follow these comprehensive steps:

1. Choose the Right Pump

Start by selecting a pump that matches your project’s requirements:

• Sunspray 700: Ideal for small features with a head height of up to 1.2 meters.
• Sunspray SE 1000: Great for medium-sized water features and cascades with adjustable flow control.
• Sunspray SE 2000: Best for larger water features with a maximum head height of 2 meters.

2. Design Your Feature

Decide on the layout and style. Use pots, stones, or other creative elements to create a cascading effect. Remember, the design is up to you—let your imagination run wild!

3. Set Up the Pump

Setting up your solar pump is one of the most crucial steps in creating a functional and efficient water feature. A proper setup ensures optimal performance and longevity for your system. To provide a clear, practical example, we’ll use the Solar Pump Sunspray 700—a versatile and popular choice for small to medium-sized water features—as our reference. While the basics apply to all pumps, including the Sunspray SE 1000 and Sunspray SE 2000, the following guide will focus on the 700 to showcase the simplicity and effectiveness of the process.

Step 1: Position the Pump in the Water Feature or Reservoir

The placement of the pump directly affects its performance and efficiency. Start by positioning the pump in your pond, reservoir, or chosen water feature at the desired depth. If you’re using a cascading setup, the pump will be placed in the base reservoir (e.g., the bottom tray or container that collects water).

• Optimal Depth: Place the pump at a depth where it is fully submerged in water. This ensures the pump doesn’t run dry, which can damage its motor.
• Higher Placement for Efficiency: The higher you place the pump within the reservoir (closer to the water’s surface), the shorter the extension tube or tubing length needed. Shorter tubing results in stronger water flow and higher efficiency.
• Weighting the Pump: If your pump is lightweight and tends to float, use small stones or a purpose-built pump weight to anchor it securely in place.

Step 2: Connect the Pump to the Solar Panel

Locate the 5-meter cable attached to the pump and connect it securely to the solar panel. The Sunspray 700 comes with a long cable, giving you flexibility in positioning the solar panel for maximum sunlight exposure.

• Position the Solar Panel: Place the solar panel in a sunny location, ideally angled toward the midday sun to capture the most energy. For optimal performance, ensure there are no obstructions like trees, buildings, or overhanging structures that might block sunlight.
• Secure the Cable Connection: Make sure the connection between the pump and the solar panel is tight to prevent disconnection or water damage.
• Tip: If you’re working with a larger feature or need additional flexibility, consider using an extension cable (compatible with your pump model) to increase the distance between the pump and the solar panel.

Step 3: Adjust the Fountain Spray or Cascade

Once the pump and solar panel are connected, it’s time to adjust the water feature to your desired effect. Depending on whether you’re creating a fountain or a cascading water feature, follow the steps below:

• For a Fountain Spray: Attach the provided fountain accessories to the pump outlet. Adjust the height of the pump in the water to achieve the desired spray effect. The closer the pump is to the surface, the higher and stronger the fountain spray.
• For a Cascading Water Feature: Attach a 12mm internal diameter tubing directly to the pump outlet. This tubing will carry water to the top of your cascade. Aim to keep the cascading height at or below 1.2 meters for optimal flow. While the Sunspray 700 can pump water up to a maximum height of 1.6 meters, the flow rate decreases as height increases.

Flow Rate at Various Pumping Heights

The Sunspray 700 delivers different flow rates depending on the height of the water being pumped. Here's a quick reference:

Height	Flow Rate (Liters Per Hour)
0m (at the pump outlet)	700 LPH
0.2m	620 LPH
0.4m	540 LPH
0.8m	360 LPH
1.2m	180 LPH
1.4m	100 LPH
Max Height: 1.6m	~

Additional Tips for Best Performance

Follow these extra tips to ensure your pump and water feature run smoothly:

• Keep the Pump Clean: Regularly clean the pump to prevent debris or algae buildup that can clog the motor or reduce efficiency.
• Maintain the Solar Panel: Wipe the solar panel clean with a damp cloth occasionally to remove dirt, dust, or bird droppings that might obstruct sunlight absorption.
• Experiment with Placement: Try different pump depths and panel positions to find the perfect balance between spray height, flow rate, and energy efficiency.

Conclusion

Once the pump is installed and connected to the solar panel, it will automatically start working as soon as sunlight hits the panel. Whether you’re using the pump for a dynamic fountain spray or a tranquil cascading water effect, the Solar Pump Sunspray 700 will bring life and beauty to your garden in no time!

4. Install the Solar Panel

Find a sunny spot for the solar panel. If your panel doesn’t come with a mounting bracket, you can easily make one using the aluminum frame. Secure it to a wall or position it on the ground using a DIY stand.

5. Connect and Test

Fill the reservoir with water, connect the pump to the solar panel, and test the system. Adjust the flow rate as needed.

Advanced Tips for Your Solar Water Feature

How to Hide Wires

Concealing the cable between your pump and solar panel is easy. Use a spade to create a narrow groove in your lawn, lay the cable inside, and press the grass back down. Your garden will look seamless, and the wires will be protected.

How to Mount Solar Panels

If your panel doesn’t come with a mounting option, make one using the frame. Secure the frame to a wooden or metal bracket and attach it to a wall or fence. Ensure the panel is angled towards the sun for optimal performance.
