45 Watt Solar Panel Kit – What Can it Run?

When you think of solar power, you probably picture a small panel on the roof of a cabin or home somewhere in the country. You can run your appliances using solar power with the right kit.

A solar panel kit is an affordable way to bring solar power into your life without spending thousands on individual components. Thanks to a solar panel kit, it has everything needed to get started with solar energy on a smaller scale than is typical. 

There is a couple of different length of solar panel kits available for purchase. Keep in mind that some have just one or two panels, and others have different sizes and wattages.

How can you know which one will suit your needs when there are a lot of brands that you can choose from? Read this article to learn more information about these fantastic kits and whether this type suits you!

The 45-Watt Solar Panel

The 45-Watt Solar Panel is one of the most popular solar panels on the market. It is an excellent panel for those looking to reduce their carbon footprint or save money on their electricity bill. Solar modules convert solar energy into usable electricity using common principles.

They can gather sunlight and convert it into electricity. For example, suppose you have solar panels that generate electricity using only sunlight. This would reduce your reliance on the grid and, as a result, lower your electricity cost.

In that case, you’ll be able to power your appliances, like the AC unit and perhaps even your entire house, without paying for electricity from the municipal grid. The output of these solar panels is 45 watts. 

Because they come in many shapes and sizes, choosing the right solar panel is challenging. The wattage of a solar panel is typically indicated on the panel. It means the panel’s electricity production under optimal weather conditions.

We suggest asking the following questions when contemplating whether to purchase a solar panel. What you want the panels to power and how much room you have for placing them are essential issues to consider. 

With a 45W solar panel, you can generate instant power or store energy in a power storage device or generator. A 45-watt panel is highly versatile, but there are other choices available that serve their quality.

If you want something more powerful, you should consider how much a 100-watt solar panel would run. Now that we’ve covered the basics, let’s examine the 45-watt solar panel in more detail. 

Who Are They For?

There are two kinds of solar panels, which are 45- and 50-watt. They are suitable for low-power products and activities.

If you are frustrated every time your mobile phone runs out of power on a weekend camping trip, you want some air from a fan, or you want to keep a few beers chilled on a fishing expedition, these choices might be ideal.

While you may connect a series of 45-watt panels to power your whole house, we wouldn’t advise that. Smaller panels have more limitations than larger ones in terms of power production per square foot, resulting in a higher price tag.

That does not mean that smaller panels are not suitable for household use. If you live in a location that experiences frequent power outages due to severe weather or storms, a 45-watt solar panel is ideal for keeping the lights on.

You can link a battery pack to a power inverter to power multiple devices, even if it takes a while to charge it fully.

How Does the 45 Watt Solar Panel Kit Work?

Three 15-watt 12-volt amorphous silicon solar modules make up the kit. After assembling the frame, you attach the three panels to it. A 45-watt output is provided by the three panels working together.

The frame must be made. After connecting the frame, you mount the three panels on it. However, if you attach the middle panel first, it will be easier. 

  • Align the panel mounts with the frame’s top and bottom mounting holes. Secure the panels to the frame by screwing and bolting them on. 
  • You now connect the three wires from the 15-watt solar modules to the splitter cable. You then link the splitter cable to the extension cable. 
  • After that, connect the extension wire to the charge controller. You then link the battery terminals to the charge controller. A big LED readout on the charge control box will display the voltage. Everything will function properly, and you’ll be able to tell immediately.

What Can a 45 Watt Solar Panel Power?

People commonly want to know what devices their new solar panels are capable of powering. A typical solar panel produces 15 watts of power, so if you’re buying a smaller panel, you’ll probably want to know if it can power your living room setup.

It would be a waste of money to purchase a solar panel to power your entire living room setup if it couldn’t even power a living room lamp.  3, 6 and 12 volts are part of the kit. 

Therefore, when considering buying a 45-watt solar panel, you should research its capacity and typical applications to ensure you’re getting what you desire and answer the question in your mind.

A 45-watt solar panel can provide enough power to charge a 12 voltage battery. It can provide enough power to run a small appliance, such as a laptop, for a short time. Below is a list of common household devices that a 45-watt solar panel can power:

  • Lawnmower
  • A solar panel with less than 100 watts of power is a suitable alternative for charging 12-volt batteries.
  • RV
  • Boat
  • Car
  • Camping lights and outlets
  • GPS

A 45-watt solar panel is not suitable for powering your whole home or campsite. Although a 45-watt solar panel does not provide sufficient power for your entire household, it is a worthy purchase because of its portability.

The benefit of a 45-watt solar panel is its compact size, making it portable. These solar panels are small enough to be carried anywhere you go, whether traveling by RV, boat, or any other means of transportation.
