Solar Generator Reviews – Which One is The Best?

A solar generator is a system that captures energy from sunlight using photovoltaic (PV) cells mounted on panels. The harvested energy is then converted into electricity in the form of direct current (DC), and then inverted into alternating current (AC) before being deposited into a battery bank.

Depending on the number of panels and batteries used, a solar powered generator can power anything from small appliances and laptops to entire households. However, unlike the conventional portable power generators most small-to-moderate models only produce enough power to charge devices like laptops, smartphones, tablets, and televisions. In this guide, you’ll learn how to choose a solar generator after being introduced to some of the most popular systems in all shapes and sizes.

Why Should You Get the Best Solar Generator?

The most obvious advantage solar generators have over fuel-powered generators is that they’re the “green” eco-friendly alternative. The ability to harvest power without fuel is not only better for the environment, it also equates to no ongoing costs associated with purchasing gasoline, propane or any other fuel source.
This not only saves the owner money on electricity bills in the long-term, it also provides a reliable and independent method of power generation that relies merely on sunlight and the proper functioning of its parts.

In addition to cost-effectiveness, reliability, and eco-friendliness, here’s a more comprehensive list of 10 reasons why most people find it advantageous to invest in the best solar generator:

1. Generates cheaper energy – If you calculate the cost of electricity per watt over a 5-year period, even with maintenance accounted for, solar generators are always exponentially cheaper than fuel-powered generators.

2. Decreases utility bill and grid reliance – Even if your panels only produce enough output to cover 25% of your home’s electricity needs, that would still be a sizable chunk of the energy bill each month.

3. Smaller portable solar generators are perfect for camping – There is a wide range of portable power generators being especially useful for camping.

4. Neutral carbon footprint – Solar generators won’t produce any greenhouse gases or byproducts that are harmful to the environment.

5. Suitable for summer use – Solar generators thrive in the summer sun, and since they do not emanate heat they can be used in hot climates without causing discomfort or heat-related fire hazards.

6. More compact and portable – Even the smallest fuel-powered generators are bulky in comparison to the slender panels and flexible setup of the best solar generator.

7. No potentially deadly fumes – Fuel generators need to be used in well-ventilated areas to prevent a buildup of potentially fatal carbon monoxide fumes. Solar generators carry no such risks.

8. More reliable when fuel is not available – In times of emergency, when fuel is not easily accessible, solar generators will still be in use.

9. Power can be stored for later usage – The system’s battery pack can store power, whereas a fuel-powered generator can only provide power while running.

10. Utility companies will pay for your excess electricity – If you expand the setup by adding enough panels, you can route the excess power to your city’s grid and receive a check from the utility company every month instead of having to pay them.

What Do You Need to Know Before Buying One?

Most solar generators generate just enough electricity to power household appliances for several hours at a time. However, some of the more powerful systems can be used continually and are expandable, allowing you to add more panels to increase your solar energy production capabilities.
The main job of a solar generator is to harvest radiation from the sun’s rays, process it through an inverter to produce an AC output, and store the captured energy in a deep-cycle battery setup.

Main Components of Solar Generators
In order to facilitate this process, a solar generator setup typically consists of some of the following components:

* Solar modules/panels
* Power inverter
* One or more batteries, typically deep cycle
* Solar controller
* Smart battery charger
* Pre-wired transfer switch
* DC inverter fuse & cable install kit
* Inverter remote
* Output cables
* Mounting hardware

While not all models include all of the above components, this list describes an optimal feature set for a well-equipped solar generator. Aside from the main components, there are a number of additional features that vary greatly depending on the model.
Any model that comes with all of the features listed below would be an ideal choice, as long as it meets your wattage requirements. These perks are what distinguish the different solar systems from each other.

Extra Features
Here are some extra features you might want to look for in the best solar generator:

* USB charging outlets
* Ability to charge from a wall outlet or car charger
* Carrying case
* Tripods/solar panel stands
* Continuous duty rating (approved for ongoing use)
* Silent operation
* Easy adjustment of panels
* Remote control for the inverter
* Expandability

By taking the above features into account before conducting your final comparison, you’ll know exactly what you’re looking for beforehand. Be sure to note the overall quality of the materials used in each component and see if there are any complaints regarding functionality or durability by reading our solar generator reviews.
Researching each component individually to determine which type you’d prefer can also help you prepare for the shopping around process. After learning about the above components you’ll be knowledgeable enough about the system to make an informed decision.

How To Buy The Best Solar Generator For Your Needs?

Aside from perks like extra USB ports and conveniences of that nature, the main features that might make one solar generator preferable over another include:

* number and wattage of panels
* total solar photovoltaic output level
* battery capacity
* included components
* inverter power rating
* inclusiveness of the set – Some sets contain all the pieces you need to get started, whereas others are more compact and contain the minimal components to operate a camping-oriented setup.

The output wattage of the solar panels is primarily what determines how much electricity you’ll be able to capture at one time. Be sure to check the power rating of the inverter as well; a higher power rating means the system can deliver more electricity at once.
In most cases, a solar generator is only expected to produce enough electricity to run your appliances during an emergency outage. However, expandable systems can incorporate enough panels added to power an entire house.

Determining How Many Watts You Need
To determine how many watts of output you’ll need to power all of your devices/appliances simultaneously, check the labels to determine the peak watts per hour, which is the amount of electricity it uses when all features are enabled.

Always use peak usage numbers to calculate your solar energy needs when adding up the power usage of multiple appliances.

Follow these 3 steps to determine how many watts your solar panels should be able to output:

1. Determine average daily or monthly usage – By dividing the monthly average usage amount (shown on your utility bill) by 30 you get your average daily usage amount in kilowatt-hours (kWH). You can also use an electricity monitor to determine a more accurate rate.

2. Add a cushion to your daily average – Next, add a 25% cushion to your average usage to account for the fact that solar panels are not always 100% efficient in all weather.

3. Choose a system with sufficient solar output – After determining how many watts you need, choose a system that accommodates your needs. You might need to go with an expandable system and add too it to reach your desired output level.

Types of Solar Power Generators

Now that you know exactly how much solar energy you’ll need to achieve your goals, a basic comparison will help you choose from one of the types of solar power generators below:

* Compact portable solar generator (perfect for camping, travel, boats, RVs, etc.)
* All-inclusive sets for emergency power backup (fastest and easiest route to a complete home setup)
* Expandable solar generator systems (start small and expand according to your needs)
* Car-compatible solar generator systems (can charge via sun or car)
* Miniature device charging sets (for smartphones and tablets)

With the above information in hand, anyone should be able to make an expert decision to select a perfect model for their unique energy needs and preferences.
