The Complete Solar Panel Kit Buyer’s Guide

Finding the Right Solar Panel Kit For Your Needs

Before diving deep into the world of solar panels, you should first consider a few different variables. We’ve covered several of the most important questions, although there will be more depending on what you plan to power with your solar panels.

What will you be using your solar panel kits for?

As with any big purchase, it’s important to determine why you want to invest in a piece of equipment. There are several different scenarios that call for a solar panel kit, and each one requires different hardware and accessories. By determining your specific needs before purchasing, you’ll save money and time down the road.

Several Common Uses Include:

  • Powering small residential or commercial buildings
  • Using it as a backup power system
  • Powering an off-grid cabin or shed
  • Charging vehicle batteries
  • Powering small appliances on an RV or boat
  • Charging small electronic devices, like laptops or phones

One of the biggest considerations is whether you want to power a small or large system. Generally, small loads (like small appliances) can be effectively run off of 100-600W systems. Larger loads (like entire households) will need a minimum of 1500W. Most DIY solar panel kits run in the range of 100-400W.

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

If you’re looking to power appliances on the go, you’ll need something more portable. Most standard solar panel kits are designed to be permanently installed in one location, whether that is on the roof or the ground. You can certainly permanently install a panel on the roof of an RV, but this may not be the most suitable option for everyone.

There are several portable solar kit models that are designed with travel in mind. They offer features such as foldable or flexible panels, pre-wiring, pre-drilled holes, pop-out stands, lightweight materials, and durability. Generally, these kits are 100-200W as anything more would take up extra space and double the weight.

If you’re looking to use your solar panels to charge your boat batteries or appliances on the water, rather than while parked on land, you’ll also need marine-friendly equipment. Some kits offer marine charge controllers and waterproof panels.

However, it may be best to purchase a solar panel kit that doesn’t include a charge controller, battery bank or inverter. That way you can purchase the best marine equipment separately to guarantee quality in extreme conditions like water exposure.

How many solar panels will you need?

The number of solar panels you’ll need to meet your needs depends on a few main factors: the wattage of the individual panels, your average power consumption, and the amount of light you receive daily. This all requires a bit of math:

  1. Determine your total daily electricity load

Your total daily electricity load (kWh) = total wattage of your appliances (amps X volts) X number of hours they will be turned on

  1. Calculate how many solar panels you need

Number of solar panels = total daily electricity load (Whs) / hours of sunlight X individual panel wattage (W)

For example, running four 50W light bulbs (a total of 200W) for 8 hours would mean a total daily electricity load of 1.6 kilowatt hours (kWh). If you receive an average of 5 hours of sun per day and are purchasing 100W panels, then you’d need 3.2 panels. This means 4 100W panels would comfortably power your light bulbs.

Do you already own an external battery bank or solar charge controller?

No matter what you plan on charging with your solar panels, you’ll always need a solar charge controller and a battery. Most kits don’t come equipped with both. Generally, more comprehensive kits will include a charge controller (MPPT or PWM), but not a battery.

You’ll need to purchase these essential accessories separately if you don’t already own the equipment. Depending on the type and model you decide to use, this can drastically increase the overall cost of your solar system. Keep in mind that MPPT solar charge controllers are more efficient (and expensive) than PWM controllers.

Are you an expert in solar panel systems?

Most homeowners are unfortunately not experts in solar panel systems. However, this shouldn’t be an inhibitor to installing an eco-friendly and cost-effective solar panel on your home. Modern technology has made it so it’s relatively simple to install solar panels on your own.

If you’re new to the solar market, a more comprehensive and well-equipped kit is the best choice. Rather than fussing with the technical details of which extra battery bank or charge controller you should buy, you can simply purchase all of it in one bundle. These are sometimes more cost-effective as well, although you won’t have much control over the quality of the extra equipment.

Keep in mind that most companies offer excellent customer support services and are able to answer any technical questions you may have. If you encounter difficulties installing or maintaining your system, it’s always best to give them a call and consult their experts if you aren’t one yourself.

Solar panel systems are relatively delicate, rather expensive, and sometimes dangerous if not handled properly, so it’s important to know what you’re doing before making any modifications or purchasing decisions.

Selection Criteria: How We Ranked the Best Solar Panel Kits

Based on our specified criteria, we’ve narrowed down a competitive list of options to feature the 6 best solar panel kits.

Our rankings place a special emphasis on reliability and value for the money. They also take into consideration the quality of the equipment, the wattage, the volts and the designated use.

Watts

Most standard solar panels are 100W. Each kit can contain anywhere from 1 to 12+ panels, with a combined wattage of 100W to over 4,000W.

The combined wattage is a determining factor for whether the kit can be used for small or large loads. The average homeowner is looking to power a few small devices or appliances and will only need a small load kit.

A minimum of 100W is enough to power a laptop or refrigerator. Our rankings base the standard wattage at 100W and will not include anything less as it is relatively useless for practical applications beyond powering a single light bulb or charging a phone. We’ve also included a max wattage of 3,600W as most homeowners will not need more power than this kit can provide.

Volts

The number of volts the kit produces will determine the type of battery you will need to purchase. Generally, most panels produce 12V. However, larger capacity kits can service up to 48V.

You’ll need a minimum of 12V to power basic appliances and devices. If needed, you can also purchase an inverter to convert the volts from DC to AC for more specialized uses.

Equipment

Each kit will come with solar panels, some variation of wiring or connectors and hardware. More comprehensive kits will also include solar charge controllers, batteries, inverters and specialized hardware. The more equipment that’s provided, the better, as it generally costs less to bundle items. Also, you’ll know with certainty that all parts are compatible.

Some may opt to purchase their own equipment as it offers more room for customization. For example, those looking to install a panel on a boat or in an RV will need different features. In this case, it may be better to purchase a simpler kit that just provides the panels and hardware.

Frequently Asked Questions (FAQ)

Are solar panels expensive?

Depending on your needs, most solar panel kits are incredibly affordable for the average homeowner. Those seeking to power small loads can find kits for as low as $100. However, if you’re looking to power a large load, like an entire residential building, then you’ll need to cough up $5,000 or more for all the equipment.

Solar panels are an investment, rather than an expenditure. Considering the average residential utility bill in America is more than $100 per month, your investment will pay itself back in as little as a few years. It also has the added benefit of decreasing your reliance on non-renewable energy sources and location dependence.

As technology continues to advance, solar energy systems will continue to decrease in price. Most companies also offer warranties of up to 25 years, with additional warranty options for efficiency ratings and accessories. While the upfront cost may seem like a lot at first, it’s a worthy and safe investment for homeowners looking to go off-grid.

What’s the difference between polycrystalline and monocrystalline panels?

The material the solar panels are made of affect the efficiency of the overall unit. Solar panels are generally manufactured with either monocrystalline or polycrystalline solar cells. They are both made from crystalline silicone. Monocrystalline panels use a single continuous crystal structure, whereas polycrystalline panels use many.

Monocrystalline panels are more efficient because they are made with the highest-grade silicon. Some industrial panels can convert as much as 22.5% of sunlight into energy. These panels are also lighter and smaller because they require less space to produce equivalent results.

Will I need to purchase extra equipment or accessories?

Some kits come equipped with everything you need to start your solar panel system. However, most do not. In order to create a fully-functional solar system, you’ll need at a minimum:

  • Solar panels
  • A solar charge controller
  • A battery
  • Wiring and connectors
  • Mounting hardware

Most kits don’t come with a battery, so you will need to purchase that separately. Otherwise, you may need to purchase a solar charge controller if it’s not included. MPPT controllers are the most energy-efficient, whereas PWM controllers are a cost-effective option for small loads.

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

All of the kits that we’ve featured in our rankings are able to be installed independently. They don’t require any special tools or know-how and relative novices can assemble them if they have thoroughly read the instruction manual. For those with little to no experience in electrical engineering, it may be best to consult a professional before messing around with wiring and electrical components.
