Buyer’s Guide: Before You Buy A Solar Panel Kit

Buying a solar kit can be an expensive investment, so make sure you know exactly what you’re getting. In this section we run through the key features you should be looking at, and the steps you should be taking before you buy.

  • Know exactly what you’re looking for.

By this we mean to make sure you know how much energy you need to harvest, and how big a solar array you need to to provide this kind of energy. If you’re not sure how to do this then check out the next section ‘How to Size Your Small Solar Power System‘.

There’s a second point here and that is to make the decision about going off-grid or staying grid-tied.


  • Off-grid or grid-tied?

Grid-tied means that your installation is metered. You are credited for putting any excess energy back into the grid. These systems need to be approved by your local energy utility before they can be used. To be grid-tied you would need a permanent residence.

Grid-tied systems don’t use batteries as energy is just taken from the grid when needed. This means that they are more efficient. The deep-cycle lead-acid batteries that are commonly used in off-grid installations, only run at about 80% efficiency.

The inverters used in grid-tied systems are usually more efficient too. They are cheaper and some are even fan-less.

Off-grid means complete energy independence, with no ties to the national grid. Off-grid solar kits are perfect for the traveler, with no fixed address. The real bonus here is that you are able to travel where you please and harvest energy from anywhere. These systems aren’t quite as efficient as grid-tied systems, but that’s just the price you pay for freedom. A solar-powered tiny house would usually fit into this category.

  • Think about installation.

Have a firm idea about where you will install the panels. Most kits don’t come with racks to mount them on, and installing them on the roof isn’t always possible. Roofs aren’t an ideal place for installation, especially on tiny houses. There usually isn’t much space on the roof, and having them up there makes cleaning and maintenance very awkward.

Remember, you want the most sunlight possible in order to yield the most energy. If you plan to move around a lot, then having some panels that you can carry to the optimum spot might be more practical. If you have an RV, tiny house, or boat and you’re able to move your home, then installing panels on the roof doesn’t make much sense. It means in hot summer months your home can’t be in the shade.

You can easily make your own racks on which to hold your panels with some good wood.

  • Check what’s included in the kit.

Though all of the systems we have reviewed are labeled as kits, they don’t all come with the same hardware. One point of note would be the batteries. Most kits don’t come with batteries included, and this is something you would have to budget for. Another point would be the racks to mount the solar panels on. The best solar panel kits come with charge controllers, panels, and wiring all included.

  • How efficient are the solar panels?

The two main choices with the panels are: monocrystalline or polycrystalline.

Monocrystalline panels are a bit more expensive, but they are more efficient. They work better in hot weather (solar panels drop in performance when very hot), and can reach efficiencies of up to 22%. Cheap solar panel kits tend to come with polycrystalline panels, which aren’t as efficient and won’t convert as much sunlight into usable energy.


  • How efficient is the charge controller?

The two main choices here are: PWM or MPPT?

PWM charge controllers are much cheaper but aren’t as efficient as the MPPT competition. If you have a small installation then the difference might not be that noticeable, but in big installations, MPPT is a must.

Find the perfect charge controller for your installation with our guide to MPPT solar charge controllers.

  • How good is the warranty?

Generally speaking, the warranties of these solar panel kits are pretty much the same. It goes something like this:

25-year power output warranty:

5 years/ 95% efficiency rate

10 years/ 90% efficiency rate

25 years/ 80% efficiency rate

5-year material & workmanship warranty

If you’re making a big investment, then make sure you’re covered by a decent warranty. Modern solar panels are a lot more sturdy than 10 years ago. The best home solar kits should last decades.

How to Size Your Small Solar Power System

So, you’ve made the decision to use solar power. The big step before choosing a kit is estimating the amount of energy that you need to produce. Are these small solar panels for tiny houses or for camping? How much of your power do you want to supply using solar? 100%? 50%? 10%?

Well, the first thing to do is to measure the power output of your home. That means identifying all the appliances that draw current and measuring their power consumption. This sounds really difficult, but it’s really not.


Step 1 – Get a power monitor

To measure the energy consumption of household appliances we need to use an electricity usage monitor. These are relatively cheap and very easy to use. We recommend the Kill-A-Watt Meter.

This meter is awesome because it can tell us how much power is being consumed at any given moment, and also how much power is consumed over time. To get these answers, all you need to do is plug your appliance in and press a button.

Even if you don’t invest in a solar installation, this inexpensive meter can show you where you can make big savings on your electricity bills.

Step 2 – Organize the appliances into groups and measure

Next, we need to split up the household appliances into 3 groups. These groups are determined according to how the appliance draws power. We need to measure the energy usage of each kind of appliance in a different way.

Next, we’ll run through what we need to calculate in each group and exactly how to do it. There’s a table at the end which shows all of the information that you should be recording.

  • Group 1 – Continuous Use

These appliances are always plugged-in and draw continuous power. This group includes things like freezers and fridges.

To measure this, we need to let the meter run for 24 hours. We need an answer in Watt Hours. To do this we press the KWH button and then multiply by 1000.

For example, pressing the ‘KWH’ button might give an answer of 0.5 kWh. We multiply 0.5 by 1000 to give an answer of 500 Watt-Hours.

With these continuous use devices, we also need to measure how much instantaneous power they use. This information is important for measuring the size of the inverter that we need.

To do this we just need to press the ‘Watt’ button.

To recap, for these devices we need to record two things. The energy usage over 24 hours (in Watt Hours) and the instantaneous energy usage (in Watts).

  • Group 2 – User Controlled

These are the devices that we control by turning them on and off. Their energy consumption is constant over the time that we use them.

This group includes things like radios, computers, fans, lights, coffee machines, and ovens.

To measure this we use the ‘Watt’ button on the electricity meter. Just press it when the device is being used.

The second step here is to multiply this answer by the number of hours each day that you use the appliance.

For example, a fan draws 60 watts and is used for 5 hours each day. The total energy consumption for the day is 60 x 5 = 300 Watt-Hours.

  • Group 3 – Intermittent Use/ Changeable Power Usage

This group of appliances are things that aren’t constantly used, but the amount of power that they draw can change over the time of their use. An example of this would be a washing machine that goes through various cycles.

This group includes devices like computers, washing machines, fancy microwaves, and rechargeable devices.

To measure this we need to record the energy usage over one complete cycle of use.

This means we need to record the energy usage of recharging a phone from start to finish, or the washing machine from start to finish. Remember, we need the answer in Watt Hours. So press ‘KWH’ at the end and then multiply by 1000.

We also need the peak energy usage in order to size the inverter that is needed. To do this, press the ‘Watt’ button during the process and record the highest reading that you see.

DeviceInstant Power (Watts)Total Power (Watt Hours)
DeviceInstant Power (Watts)Hours of UseTotal Power (Watt Hours)
DevicePeak (Watts)Total Power (Watt Hours)

Step 3 – Add Up the Power Consumption

Add up the total power consumption in Watt Hours to give your total energy requirements. Now, the number is likely to be quite large, so unless you have a huge budget, some sacrifices might have to be made. Some appliances are more important than others. Furthermore, other methods might be more energy-efficient and practical.

Step 4 – Size the Inverter

Next is to size the inverter. The inverter is a critical component as it changes the DC current produced by the solar array into usable AC current for the home.

To estimate the size of your inverter you need to use the Instant Power and Peak column in your table. By adding these up you can estimate the load that the inverter will have to handle. You need to consider the maximum amount of power that will ever be used at one time. If you plan on running a freezer, oven, radio, and lights at the same time then you have to account for this.

For example, a 2000 watt inverter can handle the energy demands of up to 2000 watts at one time.


The Kill-A-Watt meter is awesome, but there are some things that it just can’t measure. Not to worry though, as with some basic math we can work these out too.

The first thing to do is to check the device’s rating. There will be a tag on it somewhere that should give this information. If you see a value in watts then multiply this by the number of hours each day that you use it for.

If you simply see a value for Volts and Amps, then some simple math is needed. First, multiply the voltage x current. Then, multiply this answer by 0.85. Finally, multiply this answer by the number of hours each day you use it for.


An appliance is used for 5 hours each day and is rated at 120 V and 0.6 A.

Power = Voltage x Current

Power = 120 x 0.6 = 72 watts

72 x 0.85 = 61.2 watts of instant power

61.2 x 5 hours = 306 Watt Hours

Things like sump pumps are rated in horsepower. One horsepower is equal to 745 watts. If you have a 1/4 HP sump pump then you would divide 745 by 4 to get the wattage.

Step 5 – Find Out How Many Sun Hours Your Location Gets

We know how much energy we need to produce, but now we need to know how we can reach this total.

To do this we need to find out the average number of sun hours that your area receives each day.

You can find this information out using the maps on the National Energy Renewable Laboratory website. You’ll find an image like the one below but in higher resolution.


The final step is to multiply the number of sun hours you receive by the size of the solar array that you are considering.

If you receive an average of 6 sun hours each day where you live, and you are considering a 1000 watt solar array, then you can produce 6000 Watt Hours of energy on average each day.

If it’s a map like the one above, you have the information you need over an area. You would need to measure the area (in square meters) of your solar array to estimate the energy yield.

Why Use Solar Power?

Solar has only recently become a viable energy source. Recent technological advancements have significantly reduced the cost of such a system, and they are now more energy-efficient than ever.

However, they are still massively underused. Here are 3 huge reasons why we should all make use of solar energy.

1. It’s so much better for the environment.


Our most used power sources produce emissions that damage the environment. Solar power, however, is completely clean and renewable.

Now, there’s obviously energy used in making the actual solar panels, but according to this report it only takes between 6 to 18 months for this energy to be recouped, and the system to repay the energy used in its construction.

In 2015, 68% of the electrical energy produced by the United States was made using fossil fuels, biomass, and municipal and industrial wastes. These types of fuel produce many hazardous emissions, such as:

  • Carbon monoxide – contributes to the greenhouse effect.
  • Carbon dioxide – contributes to the greenhouse effect.
  • Nitrogen oxide – contributes to ground-level ozone (damages the lungs).
  • Sulfur dioxide – causes acid rain, and worsens respiratory illness and heart disease.
  • Particulate matter – causes smog in cities. Also contributes to asthma, lung cancer, chronic bronchitis, and emphysema.
  • Heavy metals (lead, mercury, etc.) – these can be very bad for human health.

The more we use renewable, clean energy sources like solar power, the less of this harmful pollution get pumped into the atmosphere.


2. It has fixed energy costs.

Ever been angered by a hike in electricity price? You’re not alone.

Utility providers seem to have complete impunity when it comes to raising prices without reason, and the price seems to rise year after year.

The great thing about solar power is that the price is set at your initial investment. If the price of oil fluctuates, that has absolutely no bearing on your electricity costs.

In fact, with a solar installation, you can wave goodbye to dreaded electricity bills. If you have a capable enough installation you can provide your household energy independently. Now, that would be a good feeling.

3. A solar energy system can earn you money.

This can happen in 2 different ways.

a) If your solar energy system is grid-tied, then you have the option of selling any surplus energy that you produce, back to the utility company.

In some states, this gets even better. The Renewable Portfolio Standard (RPS) demands that electricity companies create increasing portions of their electricity from renewable sources. Some invest in projects of their own, but many prefer to buy surplus energy from independent sources like me and you.

This has created a Solar Renewable Energy Certificate (SREC) market. If your system is creating more energy than you need then you can sell this at a premium price.

b) Solar panels can also increase the value of your property. A study from the Lawrence Berkeley National Lab concluded that homes in California add an average of $4 for every watt of power, and homes elsewhere adding $3.

That means a 5 kW solar kit could add as much as $20,000 of value in California and $15,000 in other states.

How Do Solar Panels Work?

Solar power systems look pretty simple and basic on first look. Just a shiny, black panel pointing to the sky.

However, there’s a lot of clever engineering going on behind the scenes, and that shiny, black panel isn’t the only component needed to harness the power of the sun.

The science is pretty complicated, so we’ve tried to give a rough idea of what goes on behind the scenes, without getting too technical. If you’re keen on some heavy science then check out the video below.

The common solar panels that are seen on people’s roofs are photovoltaic. This word is derived from the Greek word phōs, which means “light” and the unit of electricity, the volt. Photovoltaic (PV) panels transform the sun’s light into electrical energy for us to use.

PV panels use something called the photoelectric effect to produce electricity. This is when certain materials produce a small amount of electric current when exposed to strong light.

Solar panels use small devices called solar cells to convert the sunlight into electricity. Individually, solar cells don’t produce much electricity, but when many cells are combined to make a solar panel, we can make significant amounts of energy. These panels can then be combined to make arrays, and the effect is increased again.

Inside the solar cell, there are 2 extremely thin layers of silicon. The top layer has been treated so that its atoms aren’t stable. They actually have too many electrons and are desperate to get rid of them. On the bottom layer, the opposite is true. This layer of silicon has empty spaces and needs to fill them with electrons.


This difference in the state is the perfect situation for electricity to be produced. The two sheets of silicon are itching to transfer electrons, but they need a catalyst or conduit for the transfer to take place.

They need sunlight.

As the sunlight hits the top silicon layer, it gives the electrons the push that they need. This starts a flow of electrons between the silicon layers. A flow of electrons is, in fact, an electrical current.

However, the electricity produced by sunlight in a solar set-up isn’t perfect. It is direct current (DC), while the electricity we need in our homes is alternating current (AC). This means it needs to be altered before we can use it. This process is done by an inverter. Having an efficient inverter is a big part of any successful solar set-up.

Renogy Solar Panel Kit

renogy-solar-starter-kit-50WType: Off Grid

Power: 50 Watts

Price: $

Rating: 4.6

This Renogy solar kit has everything you need to start harnessing the power of the sun (minus the deep charge battery). It’s perfect for RVs, boats or any grid independent set-up.

The kit includes a 50 Watt monocrystalline solar panel, a 10 Amp PWM charge controller, a 20 feet 12AWG MC4 adaptor kit, an 8 feet 12AWG tray cable, and a set of Z-brackets.

The solar panel has an efficiency rating of 18.4% which makes it one of the better quality panels of this size. It also contains bypass diodes that minimize the drop in power caused by shade and low-light weather. This means it is still able to collect a decent amount of power on days when the sun is not shining so much.


The solar modules have been EL tested to ensure that there is no hot spot heating. Hot spot heating occurs when one “bad” solar cell limits the overall output of the whole unit. It can be very damaging to the physical structure of the system.

The panel also has a corrosion-resistant aluminum frame that is perfect for extended outdoor use. It has pre-drilled holes on the back that allow it to be mounted quickly and securely. The system is actually guaranteed for 25 years (power output) and 5 years for the labor and parts.

Bottom Line: This Renogy solar kit the perfect entry-level system, and one of the best solar kits for beginners. The power output is not huge, but it’s one of the best solar panels for sailboats, RVs, and smaller operations. It’s also very highly regarded by customers on sites like Amazon.

Goal Zero Yeti 1250 Solar Generator Kit

goal-zero-yeti-1250-solar-generator-kitType: Off-Grid

Power: 1250 Watts

Price: $$$$$

Rating: 4.5

Now, there are a couple of things to clarify here before we continue. The kit is rated as 1250 watts, as that is the amount of charge that the generator is capable of holding. However, it only comes with four 30 watt solar panels, which totals 120 watts (the generator can handle double this). The big difference here is that the kit uses a special generator and not an ordinary deep cycle battery. The generator can be charged in 3 ways:

  • Using solar power
  • Using a car battery
  • From the wall

These options make it a great back-up power source, should there ever be a power outage. The Goal Zero Yeti generator can then power your devices in 3 different ways:

  • Using 3 USB outlets
  • A 12 Volt output
  • Using an AC inverter to power 3 AC outputs (just like using the wall socket)

This off-grid solar kit is built with portability and usability keenly in mind. It includes carry cases, and even portable tripods to mount the solar panels.

This kit is complete and ready to go. Unlike some “kits” this one has everything needed to start using the sun’s power. It may be a bit pricier than most, but I guess that is what you pay for convenience. It wouldn’t be enough to power a home, but it is a perfect back-up system for those times of crisis.

Bottom Line: Top design and usability. It is on the pricier side, but it brings complete convenience and portability. The generator is high quality and runs silently and without any emissions.

This is the first of the larger non-grid-tied solar kits we have included. It is rated at 1300 watts and comes with an MPPT solar charge controller.

This off-grid solar kit is ideal for an off-grid power supply. In ideal conditions, it is capable of producing 6KWh each day. Of course, you will need a 24 Volt battery to store the charge (not included).

The kit comes with eight monocrystalline solar panels, rated at 160 watts each. Monocrystalline cells offer the highest efficiency performance for their size. They have aluminum frames that are corrosion resistant and built to withstand the effects of bad weather. They are built to withstand a wind pressure of 2400 Pascals, which works out at speeds of over 200 km/h. The panels also use by-pass diodes that ensure top performance in low light levels. The diodes minimize any drop in power.

Included in the kit:

  • 8x solar panels (160 Watts/18 Volts) with MC4 connectors
  • 8x Z-bracket mounting kits
  • MPPT 40 Amp solar charge controller
  • 16 feet solar cable
  • 6x pairs Y MC4 connectors

The solar charge controller uses maximum power point tracking. This technology is much more efficient than regular PWM technology. It has multiple built-in safety features, such as: overcharge protection, open circuit protection, overload protection, and short circuit protection. It also has an LCD display to give the current system status and charge levels.

Please note that this kit does not include an inverter or battery. If you wish to power household appliances then an inverter is needed to change from DC current to AC current. It requires a 24 Volt battery to store the charge.

Bottom Line: This off-grid solar kit has efficient and durable panels and a decent charge controller. It’s a good place to start for the larger of the kits. This size of kit would work great for a cabin or tiny house that doesn’t need huge amounts of power.

PluggedSolar 1.5kW

pluggedsolar-1.5kwType: Grid-tied

Power: 1500 Watts

Price: $$$$$

Rating: 5.0

This is the only grid-tied system on our list. It includes six 240 Watt solar panels that can be easily attached to a roof or mounts using PluggedSolar’s patent-pending technology. The kit is designed to be easily set-up, without the need to hire a professional. You can see how easy it is in this video.

Being a grid-tied system you must acquire your electricity companies approval before you try to feed electricity back into the grid. The kit comes with all of the necessary documentation for this, and the kit is UL certified (as required by law).

When you consume less energy than is made by the solar panels, the electricity goes back to the grid. This rotates the electricity meter backward, giving you credit. When you consume more power than is generated by the panels, the meter rotates forward, as it would normally.

The kit uses a UL approved grid-tied inverter. This converts the DC electricity that is made by the solar panels, into usable AC electricity. The inverter synchronizes the electricity voltage, phase, and frequency with that used by the utility company. It is then ready to be transferred to the grid. The kit is capable of producing 3000kWh of energy every year. The panels have a 25-year warranty and the system for 5 years. This kit may entitle you to a 30% tax credit.

Bottom Line: This is a great kit for getting started. It’s really easy to set-up and just requires approval from your local utility before you start getting electricity credit.

Renogy 3600W Cabin Solar Kit

RENOGY-3600W-cabin-solar-kitType: Off-Grid

Power: 3600 Watts

Price: $$$$$

Rating: 3.5

This off-grid solar kit from Renogy is rated at a huge 3600 watts. It’s perfect for powering an off-grid project like a tiny house or cabin.

This kit consists of twelve 310 watt polycrystalline panels, but it can be upgraded should you wish.

The kit includes:

  • 12x 310 Watt solar panels
  • Midnite Solar Classic 200 MPPT Charge Controller
  • MidNite Solar Combiner Box
  • MidNite Solar Quad Enclosure Box
  • MidNite Solar Mount Breaker
  • MidNite Solar Circuit Breaker (12 Amp)
  • 40 feet 10AWG MC4 Adaptor kit (pair)
  • 16 feet 4AWG Tray Cable
  • 8 feet 4A Copper Wire
  • 8 feet 8A Stranded Copper Wire (pair)
  • 4AWG Tray Cable Double Ring

The kit doesn’t include the battery packs, which you would have to purchase separately.

The MidNite Classic MPPT charge controller is one of the safest models around. It uses Arc Fault Detection to ensure the system is immediately shut down in the event of any weak points forming in your installation. This type of system monitoring is one of the safest and fastest at identifying problems. It also ensures your solar installation is safeguarded against electrical fires. A battery temperature sensor is included too.

It is also able to handle a great variety of DC input sources. It is designed to handle 12, 24, 36, 48, 60, and 72 Volt battery banks (it is rated for 79 Amps). The MidNite Classic controller includes solar, wind, and hydro MPPT modes. This means it is designed to regulate the DC input from all of these kinds of inputs. It also includes a voice-guided help system that walks you through the installation process. Using MPPT technology, it is much more efficient than regular PWM based systems. This is really important with these larger installations.

The MidNite Solar MNPV6 combiner box is perfect for outdoor use and has room to further upgrade the system.

Bottom Line: The system is the perfect size for small off-grid installations that need to power a few household appliances. It uses a quality charge controller to safeguard the system, and it has great solar panels for tiny houses too.
