Buying Guide: Things to Consider When Buying A Solar Panel Kit

Buying a solar kit can be an expensive investment, hence it is important to know exactly what you are looking for before making the move.

Some of the major considerations you will have to make include; the amount of energy you need to harvest, how big a solar array you need to provide this kind of energy, and whether you want to go off-grid or stay on-grid.

This guide will look into various factors that will allow you to make an investment that is worthwhile as follows;

●     Your power consumption or load 

The amount of electricity you consume per day is a key consideration as you decide your solar kit needs. Look at your energy consumption habits, and look at the lowest possible, bearing in mind that energy conservation is also energy generation. 

The kind of appliances that use electricity and their capacity in terms of wattage is a key consideration in determining the power load.  You do it by establishing the wattage of your appliances as indicated on the appliance or instructions manual. Identify all 12 volts electrical appliances, how many watts they consume, and identify how many watts you consume daily by estimating the number of hours you would use each appliance daily.

●      Wattage

After identifying the amount of energy you need in your house, next will be identifying the correct equipment and size that is required to meet your consumption. A major consideration here is the solar panel, its wattage, and size.

Solar panels have different wattages depending on use. Most standard solar panels are 100W. A kit may contain a number of panels, and a combination of panels will provide the wattage that you need, depending on your load. A laptop or a refrigerator can be run on 100W.

There are different types of solar panels to choose from. These include;

  • Mono-crystalline panels; made of single silicon crystal doped silicon cells. They are a bit expensive but most efficient.
  • Poly-crystalline: made up of more than one doped silicon crystal, these are cheaper and less efficient than mono-crystalline.
  • Amorphous: require more space to generate electricity as compared to mono and poly-crystalline solar cells.
  • Thin-film: light in weight, cheaper

●     Efficiency rate

An important indicator of solar quality is its efficiency rate. That is how well a solar photovoltaic cell can convert sunlight into electricity. The best solar panels on today’s market have an efficiency rating of approximately 22%.

You should closely note the efficiency of the solar panel, installation space, and maximization of electricity production before buying a solar kit.

●     Performance

The performance of the solar panels is also a factor to consider. Measured through a temperature coefficient rating, it will give you an idea of how your solar panel performs in less-than-ideal conditions. Solar panels work better at lower temperatures. The ideal temperature is 25° C/77° F.

●     Battery Voltage

If off-grid, you will require batteries to store power. It is important to note that the number of volts the kit produces will determine the type of battery you will need to purchase. Most panels produce 12V. Larger kits can service up to 48V.

At a minimum, a 12V 100 Amps battery would be able to power your basic appliances and devices. An appropriate inverter can be used to convert the volts from DC to AC for more specialized uses.

Please note that not all solar power kits will include batteries. However, if power-cuts are a major problem in your area, go for a kit with batteries.

●     Charge Controller

Identify the appropriate charge controller. You identify this by use of the amps produced by your panel and the type. Charge Controllers are categorized into two, PWM and MPPT.

  • Pulse-width modulation (PWM) charge controllers, are the older and somewhat less expensive version and could be up to 25 percent less efficient.
  • Maximum Power Point Tracking (MPPT) charge controllers are newer and more expensive and efficient in terms of capturing the power produced by your solar panels.

Your budget is the major determinant here, though MPPT would be ideal. An additional panel would also come in to offset the efficiency loss of a charge controller.

●     Inverter

Not all appliances will run on DC that is produced by solar panels. This is why you need an inverter to convert DC to alternating current or AC.

You may go for a kit that has a string inverter, that is connected to an array of solar panels or a micro-inverter is attached to each solar panel. Kindly note that the string inverter is cheaper and has a lesser life compared to the micro-inverter.

Other factors to consider when purchasing a solar panel kit include;

●     Kit contents

A solar kit has several components that come with it. At a minimum, a kit has;

  • Solar panels,
  • Charge controller (for off-grid systems),
  • Wiring, to connect the solar panels to the charge controller.

Bigger and more advanced kits have the following;

  • Mounting hardware to connect solar panels to the roof.
  • Wiring to go from the charge controller to the battery and from the battery to the inverter.
  • Fuses
  • Inverter,
  • Battery
  • Installation manual (important for DIY)

It is important to note that the more equipment that’s provided in a kit, the better, as it generally costs less to bundle items, and it also assures parts compatibility.

●     Warranty

Most companies will offer a warranty to guarantee the quality of their products. Checking the terms of the warranty is important. A key condition in any warranty is the term. For solar panel kit components, most manufacturers will offer at least a 10-year materials warranty and some offer a term of even 25 years for the solar panel. Remember, the longer the warranty term, the better the quality of the solar panel kit components.

●     Payback period

A solar panel kit will provide power (almost constant power) for a duration of up to 25 years at the same initial installation cost. On the other side, electricity supplied from the grid by your power supplier constantly increases from one year to another. In this case, consider the duration of time in which the investment in the solar panel kit will be returned by the generation of electricity from the same. This is the payback period.

FAQs for solar panel kits

●     What do solar panel kits include?

Different solar panel kits come with different components, but all offer mostly the same capabilities. The basic components are solar panels, connecting cables, fuses/breakers, a charge controller, and mounting hardware. Others may have a battery and an inverter.

●     Do I need to hire a professional to install the solar panels?

Some solar panels kits are DIY, whereas others require professionals to install. You can install simple low voltages off-grid solar systems by yourself.

As wattage increases, for example, up to 1,000W or more, solar installations become more complicated hence need a professional to do it. This is more so if it involves an on-grid connection that in most jurisdictions, it is only licensed electricians who are allowed to actually work in your electrical panel, and you can only hire one from the panel to do the installation.

●     Are Solar Energy Kits Worth It?

If you buy a kit, rather than separate solar power components, the complete energy kit will be cheaper. It will save you time taken to identify and search the different parts if you decide to buy them independently. However, buying the kit doesn’t offer the freedom to customize your kit.

●     Are solar panels expensive?

The cost of a solar kit is dependent on your needs, the seller, and the components of the kit. For an average homeowner, there are kits that go for as low as $100. On the other hand, there are bigger kits that can support an entire residential building that would cost up to $5,000 or more for all the equipment.

Remember that solar panels are an investment, rather than expenditure. And considering an average power bill of $100 per month, your investment will pay itself back in as little as a few years. However, the upfront cost may seem like a lot at first.

●     What’s the difference between poly-crystalline and mono-crystalline panels?

Solar panels are made of solar cells. The solar cells are either mono-crystalline or poly-crystalline made from silicone.

Mono-crystalline panels are made of single-crystal doped silicon cells and are most efficient but costly. On the other side, poly-crystalline panels are made up of more than one doped silicon crystal, these are cheaper and less efficient.

●     Will your solar panel kits be used on an RV or boat?

Solar panel kits can be used on your RV or boat. Since you need to power appliances on the go, you will require a customized solar panel kit, since most are designed for permanent installation.

There are portable solar kit models that have foldable or flexible panels, pre-wiring, pre-drilled holes, pop-out stands, lightweight materials, and durability that could function well on an RV or boat. They have a capacity that ranges from 100-200W.

If you want to use the kit on a boat, then you will have to look for marine-friendly equipment that would have marine charge controllers and waterproof panels.

●     What’s the difference between Off-Grid and On-grid Kits?

On-grid kits are installed to work on the grid provided by your local energy utility. They are metered and any excess energy is put back into the grid. They don’t use batteries as energy is just taken from the grid when needed. This means that they are more efficient. 

Off-grid installations are not connected to the grid. They use energy stored on batteries, and can be portable. They provide complete energy independence. 

·      What factors will affect the efficiency of solar panels?

Some of the main things that can affect the efficiency of your solar panel include the materials used in making the panel, how well the panel can handle heat and the reflective efficiency.

·      What does a solar panel kit contain?

At the bare minimum, a complete solar kit should include one or multiple solar panels, a charger controller, and a dollar cable for connecting the controller to the panel. 

Other solar panel kits also come with additional components like an inverter, batteries, cables, connectors, fuses, and mounting hardware such as brackets.

·      What can you run on a 100-watt solar panel? 

With a 100-Watt Solar Panel, you can run several low-draw appliances and devices including small devices and gadgets like phones, fans, routers,laptops, and lamps.

But, you may need to combine several 100-watt panels to get sufficient power to run larger appliances like refrigerators, HVAC systems, and TVs. 

·      Can a 300-watt solar panel run a refrigerator?

Yes. But you can’t run a refrigerator on a solar panel alone. The only way you can do this is by connecting the 300-watt panel to a battery and inverter to power up your refrigerator. Your 300-watt solar panel will charge the battery, which will then provide power to your refrigerator.

·      How is solar efficiency calculated?

Solar efficiency is calculated by determining the amount of solar energy a solar panel can convert into electricity. 

And you can calculate the efficiency of your solar panel by multiplying the amount of sunlight that reaches the ground in your area (incident radiation flux) by the total area of your panel(in square meters).  Then, divide your panel’s wattage with this number and multiply the result with 100 percent to get the efficiency of your solar panel.

Conclusion

Buying a solar kit is not an easy task, especially if you don’t have the required technical know-how. Besides the solar panel kit’s features and included components, other things you should consider to make sure you purchase the right one for your unique needs are your budget, space, and your power needs.  But, with the above list of the best solar panel kits , you can now easily find a solar panel kit that best meets your power needs whether it’s for your home, RV, or campsite.
