Why Should You Invest in the Best Solar Generator?

The most apparent 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, but it also equates to no ongoing costs associated with purchasing gasoline, propane, or any other fuel source.
You would not only save a lot of money on electricity bills in the long-term but also have access to a reliable source of power 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 five years, 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, y 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. You can store the power 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
To facilitate this process, a solar generator setup typically consists of some of the following components:

* Solar modules/panels
* Power inverter
* One or more lithium batteries, typically deep cycle
* Solar controller
* Smart battery charger
* Pre-wired transfer switch
* DC power 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, several additional features 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 plug 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 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 other conveniences, 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
  • inverter power rating
  • included components – Note that you will rarely find the solar generators which come with the panels included. You have to purchase them separately in most cases.

The output wattage of the solar panels is what determines how much electricity you’ll be able to capture at one time. Be sure to check the maximum power rating of the inverter as well; a higher power rating means the system can deliver more electricity at once.
In most cases, you can expect to charge only one small device at a time, such as a laptop, smartphone, or GoPro camera. Don’t expect to use most of the portable solar generators mentioned in this guide to power up larger appliances unless you go for a larger generator such as  Goal Zero Yeti 1250.

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 power output per hour. This is the amount of electricity it uses when all features are enabled.

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

Follow these three 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. 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 to it to reach your desired output level.

Types of Portable Solar 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-powered generators below:

* Compact portable solar generator (perfect for camping, travel, boats, RVs, etc.)
* Car-compatible solar generator systems (able to charge via sun or car)
* Miniature device charging sets (for smartphones and tablets)

Do solar panels need the sun or just light?

This is a very commonly asked question.

The reality or the answer to this is that solar panels can operate in many kinds of lights.

The reasoning behind it is like that of a radio. The fact that your radio has access to multiple FM signals, you can tune to one of them with ease.

In the same way, you can modify your solar panel according to the incident light, and this will work well with it.

The materials used in solar panels create current under exposure to natural daylight. This current is then utilized as standard electricity within properties. This type of energy is renewable and green.

The most critical thing that you should know is that the best solar generators utilize energy from natural daylight and not necessarily sunlight. The panels do need generally require sunlight to generate an electric current. Sunlight heat does not affect the production of electricity.

Direct sunlight provides typically the best conditions for solar panels to harness energy. However, even in cloudy areas, daylight rays will diffuse through the clouds and reach the solar panels.

There are modern designs of solar panels (like the ones here) that have included things like concentrators that generally use a set of mirrors and some special kind of lenses to maximize any all the rays of light that will get to the cells. In a clouded area, these devices will be 40% as useful as it would in an area that receives direct sunlight. The clearer the sky is, the more electricity the solar panels will produce.

Despite some mythical beliefs that solar panels will only work under direct sunlight, the truth is that they do not require sunlight to be operational. Simply being exposed to daylight alone is the most critical thing for solar panels to generate electricity. If you’re considering installing them on your home, RV or boat, we recommend you have a look at these Renogy 100 Watts Monocrystalline Solar Panels. They are some of the most popular in the market and continuously get stellar reviews from users who have also used them on cloudy days.

How many solar panels do you need to power a home?

Right solar panels are very efficient at harnessing the sun’s energy and a perfect alternative to supplying your home with power. However, depending on how you intend to use the solar energy like full or supplementary power source, there are various factors to consider before installing solar panels in your home.

1. The Amount of Power You Use in your Home

Knowing the amount of power you use in your home is a significant factor determining the number of panels you will need. Most people get it wrong by considering the size of their houses. You can never have the same energy usage as another person with the same house size as yours.

Because you may live alone while the other with a family, energy usage habits may differ, like keeping the air conditioning for a long time or energy-saving lights installed, among others.

The perfect approach is checking your utility bill to get accurate figures on your energy consumption.

2. Your Solar Goals

Motivations behind the installation of solar panels differ from one person to another. Knowing your specific energy goals will help you in deciding how many panels to install. They may include:

  • Full power – You may need the system to supply 100% of your home solar energy.
  • Partial power – You may need to use solar energy partially to compensate for the entire energy consumption in your house. You may be interested in a system that will generate power to be used during the day or at night to avoid paying more for utility-generated electricity.
  • Clean power – You may be interested in minimizing environmental impact by decreasing your dependence on non- renewable energy.

3. Amount of Sunlight to Expect

Solar insolation is a term used widely in matters relating to solar energy and simply refers to the amount of sunlight in a particular area at a specific time. You will find charts indicating solar insolation in your area to determine how many solar panels you will need to install to be able to harness enough solar energy to meet your requirements. For instance, people living in areas like California will receive more direct sunlight compared to people living in Seattle.

The more sunlight you are likely to receive, the fewer panels you will need and vice versa.

4. The Number of Panels that you can fit

After determining the amount of power you need to generate to sustain your home, you also need to calculate the number of solar panels that can fit on your roof. You should place them strategically to be able to access maximum sunlight. Some factors to consider include:

  • The direction of the roof – Depending on your geographical location, there are specific regions on your roof that are hit more by sunlight than others.
  • Shade – It’s not all about the amount of roof space you have, but again you need to locate spots on your roof that are not affected by shade from like other buildings and trees. The shade-less areas receive maximum sunlight.

5. Solar Panel Size

Solar panels generate different amounts of energy, mostly based on their sizes. With the knowledge of how much solar energy you need, you will be able to calculate the number of solar panels to install based on the maximum power they can generate.

Installing solar panels in your home will be beneficial as they will save you money, are durable, free of pollution, among others. Keep in mind that the more panels you install, the more energy you generate.
