No doubt, features like panel power output, charge controller type, inverter type, and durability are vital in solar panel kits. But when it comes to exceptional performance, battery capacity, inverter capacity, type of solar cells, and charge controller, peak conversion efficiency matter most.

Factors That Define the Best Solar Kits

Solar panels with high power output typically charge batteries faster. Hence, their importance to the function of solar panel kits. But charging is not dependent on solar output wattage only; charge controllers are also vital.

Solar charge controllers regulate the amount of power getting to the battery bank from the solar kit. In doing this, they do not use all the power from solar panels to charge the batteries. They convert only a part of it for charging, depending on their peak conversion efficiency.

A solar charge controller with high peak conversion efficiency directs more solar power toward charging. Hence, it will charge more efficiently. Generally, an MPPT solar charge controller is more efficient than a PWM as MPPTs pull more power from solar panels.

To power your appliances with solar energy, you need a battery and an inverter. Why? Batteries discharge direct current (DC), and home appliances generally give off alternating current (AC). Trying to power AC appliances with DC power is destructive. But since inverters convert DC to AC, you can power your AC appliances with solar panel kits if there’s an inverter.

Solar panel kits with large battery capacities are useful for heavier loads and longer periods. It checks out that the more solar power a battery can store, the more it can give out. Solar cell type determines how efficiently solar panels generate solar power. There are three main types of solar panels: monocrystalline, polycrystalline, and thin film. But of all 3, those with monocrystalline cells offer the highest efficiency.

Buyer’s Guide

Power Output

The wattage/power output of the solar panel of the kit you should get depends on how much power you need for appliances. Generally, with more appliances, you need solar panels of higher wattage.

Besides your load, the duration of sunlight in your region factors into selecting a solar kit with sufficient power output.

If you live in a low sunlight area, opt for a solar panel kit with a very high output. Solar panels with higher wattages can make up for low sunlight by generating a lot of power within a shorter period. You get to store some of the power they generate in batteries. So, when the sun sets, you can power your devices with batteries.

Inverter Type

If you want to maximize the power generated by your solar system, opt for kits with pure sine wave inverters over those with modified sine wave inverters. Generally, pure sine wave inverters waste less energy than modified sine wave inverters, so they are more efficient.

Besides checking the inverter type, pay attention to the continuous power rating. You should ensure that the inverter’s continuous power rating is higher than the total power consumption of all your devices by a safe margin. This way, the inverter will not readily go bad.

Battery Capacity

When buying solar panel kits, always go for the product with a large battery capacity. Kits with large battery capacities offer extended usage when there is no sun. They can also handle larger loads.

Charge Controller

When choosing solar kits, opt for MPPTs over PWMs. MPPTs are about 30% more efficient than PWMs. So, with an MPPT controller, you get to use more of the solar power in charging the batteries.

Besides checking the controller type, pay attention to the charging current rate. Generally, charge controllers with a higher charging current rate (amperage) charge faster than those with lower rates.

Frequently Asked Questions

Is it cheaper to install your own solar panels?

Installing solar panels by yourself might be cheaper at the start. But if you do not get the installation correctly or if you use substandard materials/products, you may end up spending more money and more time.

Which solar panels are the best quality?

Generally, the best solar panels are those with high output and high efficiency. In other words, a monocrystalline solar panel with high power production would be considered the best quality in many cases.

How many solar panels do I need?

The number of solar panels you need depends on your total power needs, the wattage of a single solar panel, and the space you have on your roof, RV, or wherever you want to install them.

So, if you need a total of 900W to power your devices for 8 hours daily and one solar panel produces 50W, you can calculate the number of solar panels you need as follows:

  • If one panel produces 50W, you get 6 hours of sunlight daily. In a day, one solar panel will produce 300W.
  • The number of solar panels you need = the total amount of power you need for devices daily ÷ the total power generated by one panel daily.
  • So, in this case, the number of solar panels you need = 900 ÷ 300 = 3 solar panels.

Theoretically, you need 3 solar panels. But to account for power losses due to various factors, you can get at least 4 or more solar panels instead of 3.


For the best outcomes, when buying solar panel kits that come with a battery and an inverter, ensure the solar panels have a high wattage and use monocrystalline solar cells. Besides that, make sure the batteries have high capacity and the kits come with a pure sine wave inverter and an MPPT charge controller.
