What Are The Best Solar Panel Kits?

With the rise and adaptation of solar technology, DIY solar panel kits are available in a wide variety. Here are the 10 best solar panels kits, They are classified into two sections:

  • Complete off-grid solar panel kits for homes and small businesses.
  • Solar panel Kits for RVs, Boats, Batteries, and Gadgets.

1. SunPower Equinox System

Sunpower

This system can be easily customized for anyone. Depending on the load demand and budget of the consumer, the system by SunPower has the ability to be very fruitful if we consider “value for money”. High power generation as compared to other available solar systems in lesser space and a 25-year warranty on almost everything is commendable. This system deserves a 5/5 rating but the unavailability of costing and assumption of it being on a bit higher side is for sure a 4.5/5. 

Design: The proprietary solar system from SunPower is more of a customized offering. It depends on the space available and the type of load you are connecting to the system. The company claims 55% more energy than conventional solar panels at the same place installed for the same time scale. 

The proprietary Maxeon solar cell technology and the solar panels like the X-series manufactured in-house have an efficiency of 21% and more. The copper foundation of the solar cells and hence the solar panel make them more durable and long-lasting. The direct current from each solar panel is converted to the alternating current near the panel by a microinverter like Enphase IQ 7X. From the micro-inverter, either it is supplied to the connected load to the grid, or to the energy storage option available from SunPower as SunVault. The battery system in this system is allowed to power essential loads of the house of business in case of a power outage. 

Convenient Feature: Most or all the components are of the same company making it more reliable and aesthetically correct. The solar panels, microinverters, mounting frames, and energy storage with the help of a monitoring system make it an ideal system for homes or businesses. The system generates more power in less space, less use of hardware, easy connection to energy storage, and a lifetime warranty with ease of monitoring are very convenient features.

2. 5000 Watt (5kW) DIY Solar Install Kit with Micro-inverters [Rooftop]

5000 Watt (5kW) DIY Solar Install Kit with Micro-inverters [Rooftop]

Efficient technology and design make this solar panel kit for the ones who really want to get full use of the sun’s free resources. This solar kit will not only give financial savings in the long run but also provide energy independence. Also, you will contribute to the fight against climate change. 

This solar panel kit is available in different sizes or wattages. Depending on your monthly usage, you can select the one that adapts for you. We have classified these depending on expected power output, the number of solar panels, the area required for panels, and the expected price range. 

Equipment Specifications for 5kW solar panel kit:

Other components required are to be bought from your nearest Home Depot for which a list will be provided. 

Design: The Phono Solar, 310W, 60 cells, mono-crystalline, all-black solar panel has around 19% efficiency in standard conditions, which is considered good. For a 5kW system, 17 solar panels are connected which requires 400 square feet of roof space. The micro-inverters are attached along each solar panel to convert direct current to alternating current for further supply. For a system facing south in the USA or Canada, this system can produce 320-850 units per month if 5 hours of sun is available each day.   

The electricity supply from the solar panel kit is then supplied to a junction box from where it is supplied to loads at home or if in excess it is supplied to the grid from the point of common coupling.  

Convenient features: The micro-inverter is one of the advanced technologies that solve some acute problems of a string inverter. This technology in a solar panel kit on your rooftop makes it safest for generating direct current electricity and instantly converting it to alternating current electricity.

Also, each individual micro-inverter on each solar panel makes it a separate entity, being only responsible for its own current and voltage characteristics. In the case of a string inverter whole system operates at the lowest voltage and current as per the shaded or lowest power output solar panel.

The solar panel kit can be expanded easily if it is necessary, required, or wanted. Again one single inverter does not decide the capable size of the solar system as per its capacity. But a micro-inverter on a solar panel can do this expansion with ease.

Pros:

  • Efficient design. 
  • Safe and sound.
  • Easily Expandable.
  • 25-year warranty for panel and inverter.
  • Ability to monitor energy production.

This solar kit is efficient and can provide electricity supply to homes or small businesses. The power optimization makes it an advanced system as compared to systems having a direct connection of solar panel array and string inverter, thus improving efficiency and performance.

The string inverter is the most mature and reliable technology that does not comply with the life of the whole system like a micro-inverter and also diminishes the possibility of expanding the system. On the other hand, a possible battery connection makes it an ideal choice for homes or businesses in need of power backup. Also if you want to use energy generated during the day at night, having a battery is a great option. 

This solar panel kit is available in different sizes or wattages. Depending on your monthly usage, you can select the one that adapts for you. We have classified these depending on expected power output, the number of solar panels, the area required for panels, and the expected price range.

Equipment Specifications for 5kW solar panel kit:

Other components required are to be bought from your nearest Home Depot for which a list will be provided. 

Design: The 310-watt PhonoSolar 60-cell mono-crystalline solar panels which appear all black in color are efficient in solar energy conversion to electrical energy. In a 5kW solar panel kit, 17 of these are connected to form an array. Each solar panel is connected to a power optimizer which refines the DC current and sends it to the battery or inverter. The inverter converts DC to AC and is supplied to the load or connected grid. 

For a 5kW solar kit facing south in the USA or Canada, getting 5 hours of sun each day for a month can generate 350-850 kWh, taking 400 sq ft. of your roof space. 

Convenient feature: To each solar panel or module a power optimizer is connected which refines and regulates the direct current generated by the panel. This is done by the MPPT or maximum power point tracking technology which optimizes the current and voltage from each panel to its optimum level. Like the micro-inverter, the power optimizer treats each solar panel as a separate entity, and any shade or redundancy in any one solar panel does not affect the output of the whole system. 

The current optimized by the power optimizer is DC to DC which is then supplied to the string inverter. The string inverter or centralized inverter converts DC to AC or alternating current which is supplied to the connected load or the grid via the control panel or the junction box. 

The addition of a battery is also possible in this kit if required. For the same system, Tesla’s Powerwall can also be connected and is compatible.  Having a battery is a nice option if you want to go totally off the grid and use only solar energy as your power source.

9 Things to consider before choosing a solar panel kit

Choosing a solar panel kit for a home or small business can be a bit confusing if there is little or no knowledge about the same. Before purchasing our chosen options of solar kits, it will be good to understand what is required to consider before choosing a solar panel kit for home and small businesses:

Potential Of Solar Resources at Location

The potential of solar resources striking a particular surface on Earth is defined by insolation. It is the solar energy per unit area for a particular time. Understanding the potential of solar energy for a particular location is essential for designing and installation of solar energy systems. As a general rule of thumb, locations near the Earth’s equator have high insolation levels compared to locations further north or south of the equator.

A device known as a pyranometer is generally used by professional solar installers to get detailed solar insolation levels of sight. One other way to get an idea about the potential of solar radiation in your location Global Solar Atlas can be used which can also be explored to get an idea about solar energy output from your site. 

Identify Installation Area

After confirming the solar data for your location, the area, where solar panels are to be installed, should be finalized. For global locations in the northern hemisphere, the panels should face in the south direction, and for locations in the southern hemisphere; panels should face in the north direction. Solar panels can be installed on slanting roofs, flat roofs, or ground. 

Solar panels should be totally avoided from the shaded area as it affects the output of the solar system. Also, the accessibility to cleaning the panels is an added advantage. Solar panel installation areas should be carefully selected as these once installed should stay there for their lifetime. 

Another thing to be considered about the installation of panels is their slant. The solar panels are installed in a slanting manner as this slant makes them directly face the sun and get maximum solar radiation. Another rule of thumb to keep this slant is to know the latitude of your location and keep the solar panel at or about the angle the same as the latitude.

For example let us say California has a latitude of 36o27’, the solar panel in California if installed at an angle of 36o from the ground will directly face the sun.

Define Your Consumption Or Load 

What amount of electricity do you consume per day, per month, or per year is a question to make yourself more aware of your energy-consuming habits. It is a fact that energy conservation is also energy generation. To install a solar panel system or any energy-generating system for your home or business should start by defining energy consumption and if possible bringing it to the least. 

Or how much electricity do you want to consume from your solar system? Or what specific devices do you want to power your solar system? These questions should be answered before installing a solar system. Being aware of your electricity consumption or electricity supply, if available in excess makes you more energy conscious. This will not only profit you economically but also make you climate-conscious leading by example.  

So understanding your consumption or load to be supplied by solar panel kit is essential before choosing one too. 

Electricity Storage Or Battery Required Or Not

Having an off-solar grid system for your home or business is like getting out of the electricity transmission line which everyone is part of. This requires energy storage technology like batteries and also very efficient consumption of energy. 

If power cuts are not a major problem in your area which is too seldom in developed countries, batteries or energy storage can be opted out. Instead, an on-grid solar system (without batteries) is more beneficial as electricity can be supplied back to the grid and extra money can be earned or saved. 

Batteries can be used if a backup is required in case of usual power cuts or if the energy produced during the day is to be used at night. Adding a battery to a solar panel system comes with additional costs and should be thoroughly thought out before opting for it.  

Type Of Solar Panel Required

There are many types of solar panels being invented and researched. The type of solar panel means the type of semiconducting material used to make a solar cell. A solar panel is comprised of a number of solar cells. 

Mono-crystalline, poly-crystalline, amorphous, and thin-film are the major types of solar panels being commercially used. Of these mono-crystalline and poly or multi-crystalline solar panels are widely used. Mono-crystalline solar panels are made up of single silicon crystal doped silicon cells and are most efficient but costly.

Similarly, poly-crystalline solar panels are made up of more than one doped silicon crystal, these are cheaper and less efficient than mono. Doped silicon here means the silicon cells are added with impurities like phosphorous which makes them generate electricity when photons of sunlight fall on them. 

Amorphous and thin-film solar panels are light in weight, cheaper, and require more space to generate electricity as compared to mono and poly-crystalline solar cells. Depending on your space, budget, and expected payback period, solar panels should be chosen.

Type Of Solar Inverter Required

Solar panels generate direct current or DC and it is not used in our homes or businesses. DC can charge up batteries directly or equipment requiring DC to operate. To convert DC to alternating current or AC, inverters are used. 

There are two types of inverters in the market string inverters and micro-inverter. A string inverter is connected to an array of solar panels and converts DC to AC which is supplied ahead. A micro-inverter is attached to each solar panel which converts DC to AC. 

The life of the string inverter is less compared to the micro-inverter but is also cheaper than the latter. The inverter is the second most essential component of the solar system after solar panels and should be carefully chosen. The efficiency and life of the solar system also depend on the inverter which also plays a crucial role when the solar system is tied to the grid. 

Efficiency Of Solar Panel System

The amount of solar radiation falling on solar panels is not fully transmitted to the load connected to them. The efficiency of solar panels, inverters, batteries, wiring, etc all play their roles in delivering power out of the solar system. 

Some solar panel kits claim 15% efficiency and others claim 20% or more, which all depends on the type of solar panel, inverter, and wiring used. Also, the variation in sunlight during the time of day, months, and seasons vary the output of the solar system. Clouds, dust, and dander play their role too in varying the efficiency of the solar system. 

Also, with time efficiency of these components decrease and they will not give the same output continuously for their lifetime.  

Warranty available or not

Solar panel kit supplier giving warranty assurance on panels is a must when going for such installation. Solar panel manufacturers claim 25 years is the working life of solar panels. String inverters can go for 10 years and micro-inverters can go for 20 years. It depends on the type of technology used and the efficacy of the manufacturer on the tested and proven life of components. 

Payback period

In how much time the amount invested in the solar panel kit will be returned by the generation of electricity from the same? This calculation depends on the solar radiation available, the type of solar panel, and other components used. Usually, if you are able to cover the upfront cost of a solar system in 5-6 years, it is the way to go. Also if it takes 10 years, still it is beneficial. 

We have to consider the fact that the solar panel system or kit installed today will generate electricity at the same rate for the next 25 years or so. But the electricity supplied from the grid by your power supplier constantly increases from one year to another. 

It is just that your location should be not so solar energy deficient that it takes 25 years or more to pay back for your installation. 

It Is Your Turn

Solar energy is widely available in most parts of the world. According to NOAA, 173,000 terawatts of solar energy strike Earth continuously and it is 10,000 times more than the total global energy use. This availability of solar resources makes it an ideal candidate to be the prime source of energy supply for human consumption. 

Solar photovoltaic technology also termed solar PV has matured in the past decades. From the initial use of solar panels powering satellites orbiting the Earth, to the present use in charging mobile devices with integrated battery technology, this technology has penetrated society. Continuous research and development have increased the efficiency of solar photovoltaic technology and have also brought the prices low enough to compete with conventional electricity.  

Any best solar panel kit is to be chosen by anyone first depending on the amount of money that can be invested to produce your own electricity. Another factor is the amount of space and load available at home or small business which is on the basis of what a selection can be made. 

We at Earthava strive to answer all queries regarding sustainability and the environment and hope to help you live a sustainable life today and in the future.
