Solar Generators in the Garden

Using solar generators in the garden can be a great way to power your outdoor tools and equipment without relying on traditional power sources. Solar generators work by collecting energy from the sun using solar panels and converting it into electrical energy, which can be stored in a battery for later use.

Here are some ways you can use solar generators in your garden:

  1. Powering garden tools: Solar generators can power garden tools such as lawnmowers, hedge trimmers, and leaf blowers. This can be especially useful if you have a large garden or need to use your tools for an extended period.
  2. Lighting: Solar generators can power outdoor lighting such as string lights, spotlights, and lanterns. This can be a great way to create a warm and inviting atmosphere in your garden.
  3. Water features: Solar generators can also power water features such as fountains, pumps, and irrigation systems. This can help keep your garden healthy and thriving, even during periods of drought or low rainfall.
  4. Charging electronics: Solar generators can be used to charge electronic devices such as phones, tablets, and laptops. This can be useful if you need to work or communicate while you’re in the garden.

When using solar generators in the garden, it’s important to choose a model that is appropriate for your needs. Consider factors such as the generator’s capacity, battery life, and charging time, as well as the amount of sunlight your garden receives. Additionally, make sure to follow all safety guidelines and instructions provided by the manufacturer.

factors to consider when buying a solar generators for the garden

If you are considering buying a solar generator for your garden, here are some important factors to consider:

  1. Power output: One of the most important factors to consider when buying a solar generator is its power output. This is usually measured in watts and determines how much electrical energy the generator can produce. Make sure to choose a solar generator with a power output that is suitable for your needs.
  2. Battery capacity: Solar generators typically come with a battery that stores the electrical energy produced by the solar panels. Battery capacity is usually measured in watt-hours (Wh) and determines how long the generator can power your devices. Consider how long you will need to use the generator and choose a battery capacity that can meet your needs.
  3. Solar panel capacity: Consider the size and wattage of the solar panel(s) that come with the generator, and ensure they are sufficient to recharge the battery within a reasonable time frame.
  4. Charging time: The charging time of a solar generator can vary depending on the model and the amount of sunlight it receives. Consider how quickly you need the generator to charge and choose a model with a charging time that is suitable for your needs.
  5. Portability: Depending on your needs, you may want to choose a solar generator that is portable and easy to move around your garden. Consider the weight and size of the generator, as well as any additional features such as wheels or handles.
  6. Durability: When using a solar generator in the garden, it may be exposed to the elements such as rain, wind, and sunlight. Consider choosing a model that is durable and weather-resistant.
  7. Additional features: Some solar generators come with additional features such as built-in inverters, USB ports, and AC outlets. Consider what features are important to you and choose a model that has the features you need.
  8. Price: Solar generators can vary in price depending on their features and capacity. Consider your budget and choose a model that provides the best value for your money.

By considering these factors when buying a solar generator for your garden, you can ensure that you choose a model that meets your needs and provides reliable and sustainable power for your outdoor activities.

how to find the wattage requirement on outdoor tools

The wattage requirement of an outdoor tool can usually be found in one of two places: the owner’s manual or a label on the tool itself.

  1. Owner’s manual: Most outdoor tools come with an owner’s manual that provides detailed information about the tool, including its wattage requirement. Look for a section in the manual that describes the power requirements of the tool.

  2. Label on the tool: Many outdoor tools have a label or tag attached to them that provides important information about the tool, including its wattage requirement. The label may be located on the tool’s body or on the power cord. Look for a section on the label that describes the power requirements of the tool.

If you cannot find the wattage requirement using either of these methods, you may be able to find it by contacting the manufacturer or checking the manufacturer’s website. Some manufacturers provide detailed specifications for their products, including the wattage requirement.


Here is a list of common garden tools and their wattage ranges that you can use as a guideline for choosing solar generators but you must check your specific tool to be sure you select the right one:

  • Lawnmower: 1000-2000 watts
  • Hedge trimmer: 400-800 watts
  • Leaf blower: 500-1000 watts
  • Chainsaw: 1200-2400 watts
  • Grass trimmer/edger: 300-600 watts
  • Garden shredder: 2000-3000 watts
  • Pressure washer: 1000-2000 watts
  • Water pump: 500-1500 watts

Please note that these wattage ranges are approximate and may vary depending on the specific model and manufacturer of the garden tool.


calculate battery and solar panel capacity to use a solar generator in the garden

To calculate both the battery and solar panel capacity for a solar generator, you need to follow these general steps:

  1. Determine the total wattage of the devices you want to power: Make a list of all the devices you plan to power with the solar generator and their respective wattage ratings. Add up the total wattage.
  2. Estimate the daily energy usage: Estimate the number of hours each device will be used per day, and multiply that by the wattage to get the daily energy usage in watt-hours (Wh). Add up the daily energy usage for all devices.
  3. Factor in inefficiencies: Solar generators and their components have some inefficiencies, so it’s important to factor in a loss percentage (typically 10-20%) to the daily energy usage.
  4. Determine the number of days of backup power: Decide how many days you want the solar generator to be able to operate without receiving sunlight.
  5. Calculate the battery capacity: Multiply the daily energy usage (after factoring in inefficiencies) by the number of days of backup power. This will give you the total capacity of the battery needed in watt-hours.
  6. Estimate the charging time: Estimate the number of hours of sunlight you expect to receive in a typical day in your location. This can vary depending on your location and the time of year.
  7. Determine the charging efficiency: Solar panels have an efficiency rating that determines how much energy they can convert from sunlight to electricity. This rating is usually expressed as a percentage. Assume a solar panel efficiency of around 15-20% for your calculations.
  8. Calculate the required solar panel capacity: Divide the daily energy requirement (battery capacity) by the charging efficiency and the estimated hours of sunlight. This will give you the solar panel capacity required in watts.

For example, let’s say you have a total wattage of 500W for your devices, they will be used for 5 hours per day, you want to have 2 days of backup power, and you expect to receive 5 hours of sunlight per day with an assumed charging efficiency of 15%. Here’s how you would calculate the battery and solar panel capacity:

  1. Total wattage = 500W
  2. Daily energy usage = 500W x 5 hours = 2,500Wh
  3. Factoring in a 10% inefficiency, the adjusted daily energy usage = 2,500Wh x 1.1 = 2,750Wh
  4. Number of days of backup power = 2 days
  5. Battery capacity = 2,750Wh x 2 days = 5,500Wh
  6. Estimated hours of sunlight per day = 5 hours
  7. Charging efficiency = 15%
  8. Solar panel capacity = (5,500Wh) / (0.15 x 5 hours) = 7,333 watts

Therefore, you would need a battery with a capacity of at least 5,500 watt-hours and a solar panel with a capacity of at least 7,333 watts to power your devices for 2 days without sunlight in a location that receives 5 hours of sunlight per day with a charging efficiency of 15%.

In summary, when choosing solar generators for use in the garden, you must consider:  power needs, battery capacity, solar panel capacity, portability, durability and any other special features you may want such as USB ports and/or AC outlets.
