12 Volt 10 and 20 watt solar panels

Solar panels were invented in the 1950s. Ever since then, they have become increasingly popular as a source of renewable energy. One type of solar panel that has gained popularity among outdoor enthusiasts and RV owners are our small 12 Volt 10 and 20 Watt solar panels.

In this blog, we will discuss why our solar panels are a great option for water pumps and how they work.

The 12V 10 and 20 Watt Solar Panels are small photovoltaic panels that generate just the amount of current needed to run solar hot water pumps. Photovoltaic (PV) cells convert sunlight directly into electricity through the photovoltaic effect. These cells are typically made of silicon, which is a highly abundant and durable material.

Why are our 12V 10 and 20 Watt solar panels great for our water pumps?

1. Low power consumption: Water pumps that are powered by a solar panel typically have low power consumption, making them energy-efficient and cost-effective.

The efficiency of solar panels has improved over the years. Early solar panels had an efficiency of around 6%. Now modern panels can reach efficiencies of 20% or even higher. This means that more sunlight is being converted into usable electricity.

2. Compact size: They are small and lightweight, making them easy to install and transport. They’re easy to install and can be installed on various surfaces, including rooftops, building facades, or even on the ground. They can be integrated into the architecture of buildings or mounted on solar tracking systems to maximize sunlight exposure throughout the day. This allows the user to get as much use out of their solar panel as possible.

3. Ease of connection: Like all solar panels our 12 Volt 10 and 20 Watt solar panels generate electricity as the sun rises. In a solar hot water system there is no need for the pump to be running when the sun has gone down.  Our solar hot water pumps can be connected directly to our solar panels. Therefore as the sun rises, the pump starts to spin up. As the sun goes down the pump spins down.

4. Easy to maintain: Solar panels are generally low maintenance, and our 12 Volt 10 and 20 Watt solar panels are no exception. They require little to no maintenance, making them a convenient option for remote or hard-to-reach locations.

How is it that our 12V solar panels are well matched with our solar hot water pumps?

Our 12V solar hot water pumps are designed to handle a wide range of voltage. Our solar hot water pumps will only draw the amperage and wattage they need. 

Solar panels that are rated above 12V can have peak voltages outputs beyond what is ideal for pumps.  The higher the voltage, the faster the pump spins, which can reduce the life expedience of the pump.

Our 12V 10 and 20 Watt solar panels also will have an output above 12V, in full sun, but its voltage range will not peak beyond what is ideal for the pump.  Thus you will get the best life expedience out of the pump when it is attached to one of our 12V solar panels.


Our 12 Volt 10 and 20 Watt solar panels are a great option for powering solar hot water pumps due to their low power consumption, compact size, ease of connection, ease of maintenance and voltage range. They provide a reliable source energy regardless of you location.
