Solar Power Generator Buying Guide

Solar Power Generator 5

A solar power generator serves as an alternative to conventional electricity today. It helps people save electricity bills to a great extent since it uses the sun’s energy which is stored in a battery bank via solar panels and released through an inverter so that it will be utilized for standard AC power. Having your own solar power system lets you enjoy independence from the local electricity supplier, however, before you one, you have to consider  and understand its key elements, overall performance and the factors to watch out for in the plethora of systems available in the market these days.

Purchase Consideration

Battery Storage Capacity

The capacity of the battery storage is the most significant key element in the actual usability of a solar power generator. This will let you use the generator at night, when there is limited sun and in periods your energy has to exceed the amount of solar input coming in.

Batteries come in terms of amp hours (amp/hr) however, in order to get a convenient battery rating, it would be better to convert amp hours to watt hours. As a rule, not all of the rated watt hours should be utilized. Manufacturers recommend that consumers should only use 2/3 of the full capacity in lead-acid batteries so that its life span will be preserve and failures will be reduced.  You have to know the usable watt hours of your solar power generator in order to determine its capacity to run specific applications.

Solar Panels

Solar panels or solar PV input is what powers the solar power system. If you have enough solar PV input, you can use the solar generator during the day and recharge it less often after using it at night. The rate of solar panels depends on their watt-generation capabilities. For instance, a 140 watt PV input generates 140 watts of inbound generation capabilities in full sun. Generally, full sun can last until 6 hours during the day, at other times of the day, the input continues to come in but it can be less than rated.

If you want to have a system with solar tracking feature, choose a portable solar generator or a solar power with separate PV panels. Through solar tracking you can move your panels along with the sun’s arc in order to capture the best solar input continuously.

In a solar power generator, PV input is closely related to storage capacity since there is a need to store energy for a later time usage. Appropriate recharging time after depletion is within six hours or less for solar power systems that have less 2500 usable watt hours. Recharging it over this time will affect its usability.

It is important to note that allowing the batteries to sit without being fully charged or using not fully charged batteries before night usage will reduce its lifespan. Therefore, you have to keep in mind that solar generators should have solid PV input so that there is an available energy during the day, which strongly suggest the need to keep the batteries fully charged at night.

Inverter Rating

The energy stored in the battery bank of the solar power generator is released through an inverter that converts low volt DC to 120 volts, the standard AC power. This way you will enjoy the power captured from the PV panels using a variety of power applications.

Also, there areupgraded types of inverters like an inverter charger that has the ability to charge your battery bank externally through a grid or gas generator then route the incoming AC power to the batteries of the solar generator in DC form.

You will know the maximum watts you can pull from a solar generator by checking out the rates given by your inverter. If you pick a 1500 watt inverter, it allows you to pull up to that watt rate in the AC power. However, pulling the maximum watts you can get from an inverter will minimize the capacity of the lead-acid batteries in a much faster manner. To avoid this effect, opt for generators that use lithium batteries.

Component Quality

The huge factor that can affect the durability and usability of solar generators is its component quality thus, it is imperative to get components with warranties and longer life spans. American made solar controllers and inverters are proven to be durable and offer 2-5 year warranties which really ensure long term usage. Unfortunately, this cannot be the case for some of the least pricey imported components utilized by many solar generators.

Generators with plastic casing may break down over time due to natural wear and tear, heavy sun exposure and other rugged conditions. Thus, it would be better to choose solar panels that have metal casing because it can withstand exacting usage as well shield their valuable components over time against any environment condition.


Choosing a solar generator that is portable allows you to achieve on-demand usage, point of use power and solar tracking. At most, weight significantly increases due to batteries with solid storage capacity. To ease this problem, manufacturers came up with the great idea of mounting heavy solar power systems on a small, cheap plastic casing with wheels.

Indeed, proper weight distribution and bicycle wheels help to secure the capability of portable solar generators to be used in steep hills, dirt trails or potholes. Portable solar generators can be conveniently used in different locations or wheeled on ramps into a van or truck. However, it would be great if these systems are not only portable when you first tried them in the shop or in best conditions, but should work in real environments.

Balanced System Design

Considering all the key elements of a usable solar power generator will give you a good picture of an imperative need to have a balanced system design. Solar power systems would really work great if they have quality components that fit well to each other and feature ratings that support end usability.

At best, a well balanced solar power system combines the pairing of usable storage capacity, proper inverter rating and solid PV input, or in other words, havingat least 1500 watt hours storage capacity, a 1000 watt inverter and 250 watts PV input.

Ultimately, with a balanced system design and high quality components, you are assured that you are getting a solar generator usable in any environment, needs and applications.
