What Size Solar Generator Do I Need?

The size of the solar generator you need depends on several factors, including the total power consumption of the devices and appliances you plan to use, the duration of use, and whether you want a generator for occasional use or more extended periods.

Calculate the total wattage of the devices you plan to power to determine the appropriate size for your solar generator. Add up the wattage of each device and consider how long you’ll be using them daily. Multiply the total wattage by how many hours you plan to use them to get the needed watt-hours.

Next, consider the generator’s capacity, measured in watt-hours (Wh), which indicates the amount of energy it can store. Choose a generator with a capacity that meets or exceeds the required watt-hours. It’s also a good idea to have some extra capacity as a buffer, particularly for cloudy days when solar charging may be less efficient.

Additionally, pay attention to the generator’s inverter rating, measured in watts (W). This determines the maximum power it can deliver at a given time. Ensure that the generator’s inverter rating is sufficient to handle the peak power demands of your devices and appliances. Remember that your needs may change over time, and it’s often better to invest in a slightly larger solar generator than you initially require to accommodate future growth or additional devices.

How to Figure Out How Much Generator Capacity You Need

Since this might be difficult to understand, let’s illustrate this with an example. Say you have a fridge that requires 600W of power, a 5W phone charger, and four 5W LED lights. You’d like enough power to keep the fridge and lights running for six hours, but you’d only need the phone charger for about two hours.

DeviceQuantityWattageHoursTotal
Refrigerator1600W6h3,600Wh
LED Lights45W6h120Wh
Phone Charger15W2h10Wh
Total3,730Wh

In this example, you’d want a generator with a capacity of at least 3,730Wh. Remember that some electronics, like refrigerators, initially require more power to start up. Called surge power, this number will need to be lower than the peak power requirements of the devices you’d like to power with your solar generator.

Why Are Solar Generators So Expensive?

It’s a matter of perspective. Yes, you can pick up a gas-powered generator for as little as $500, although you’re more likely to pay $1,000 or more for sufficient power for your appliances and some lights during an outage. But that’s not the only cost. There is also the cost of fuel to run the generator, which will use about 1-2 gallons per hour for home backup power use for a 5-10Kw unit. Using a price of $3.50 per gallon, you’ll spend anywhere from $85 to $170 per day on gas. That can add up very quickly.

With solar generators, all the cost is up-front, and the energy to power it is free from the sun. While weather conditions will play a role in recharging your generator, the only costs you will have are for the hardware if you decide to upgrade or it breaks (which it shouldn’t). If you’re in an area prone to extended outages, you’ll want to purchase a larger capacity generator so you’re less prone to variability in available sunlight.

  • Environmental impact: Solar generators produce no emissions and have a lower environmental impact than gas generators, which produce emissions and contribute to air pollution.
  • Power output and runtime: Gas generators often have a higher power output and can run longer, making them suitable for powering larger appliances or providing backup power during extended outages. Solar generators are generally more limited in power output and runtime, depending on the battery capacity and available sunlight.
  • Initial cost and long-term expenses: Solar generators may have a higher upfront cost than gas generators. However, their long-term operating costs tend to be lower, as they do not require fuel purchases and have lower maintenance expenses.

Which solar panels do I need for the solar generator?

The solar panels you need for your solar generator depend on the generator’s input specifications, your energy requirements, and the amount of sunlight available in your location. Investing in high-quality solar panels will improve charging efficiency and overall performance, making selecting panels from reputable manufacturers with a proven track record crucial.

Look for panels with an efficiency rating of at least 18-22%. Higher efficiency panels will generate more power in a smaller area, making them ideal for situations with limited space or less sunlight. You’ll also want to ensure your panels have the necessary connectors and cables to connect to your solar generator.

What size solar generator do you need to run a house?

Running an entire house on a solar generator can be challenging, as the energy requirements vary significantly depending on the size of the house, the number of occupants, and the types and quantities of appliances and devices used. We recommend using them as backup power sources, not your primary ones. However, powering a small living area like a tiny home might be possible. Follow the steps from the answer to the first question to determine what you need.

How long do solar generators last?

The lifespan of a solar generator depends on the quality of its components, usage patterns, and maintenance. On average, a solar generator lasts 10 to 15 years or even longer. Most solar generators use lithium-ion or lithium iron phosphate (LiFePO4) batteries, typically lasting between 2,000 and 5,000 charge cycles or more, depending on the quality and usage patterns. A high-quality battery can last up to 10 years or longer with proper care and maintenance.

A solar generator’s inverter and other electronic components have varying lifespans. Inverters typically last 10 to 15 years, while other components like charge controllers and wiring can last even longer with proper maintenance. Panels can last even longer, in some cases up to two to three decades.

Is it difficult to maintain a solar generator?

Maintaining a solar generator is generally not difficult, but it does require some regular care and attention to ensure optimal performance and longevity. Here are some basic maintenance tips:

  • Keep the solar panels clean: Dust, dirt, and debris on the solar panels can reduce their efficiency and power output. Regularly clean the panels using a soft cloth, mild soap, and water to remove dirt and grime. Be gentle and avoid using abrasive cleaning tools or chemicals that may damage the panels.
  • Inspect for damage: Inspect the solar panels, cables, and connectors for any signs of damage or wear. Address any issues promptly to ensure continued efficient operation.
