1000 watt solar panel kit off-grid

One of the most common sizes for solar panel arrays is a 1000 watt installation.

In fact, the most powerful solar panels available today have a power output of about 400 watts, so to make a 1000 watt system you will need several panels joined in parallel.

While 1000 watts, otherwise known as 1 kilowatt, of solar power may not be enough to power a large home for an entire year, it is sufficient for cabins, workshops, RVs, or vans.

So for those contemplating installing a 1000-watt off-grid system, we’ve put together this guide to address some of the most frequently asked questions.

What is off-grid solar, and how does it work?

Off-grid solar systems, also known as stand-alone power systems, are typically not connected to the electrical grid but generate enough electricity using solar panels that are linked to battery storage.

Off-grid systems have historically been out of reach for many people due to the higher costs of the whole solar kit, including a charge controller, an inverter (also known as a pure sine wave inverter), and batteries.

But those costs are steadily decreasing year on year!

How does solar panel kit work?

Off-grid solar has a unique feature that other solar systems lack: the battery bank! 

With grid-connected solar kits, you don’t need to worry about a battery to store power. If your solar system isn’t providing enough power, your house will draw from the power lines still attached to it.

Like all solar panels, the off-grid installation collects energy from the sunlight and converts it into electricity. Then, it’s taken to a battery bank which stores the energy until you need it.  The difference with off-grid is that the sun is your only source of power!

To explain further, the solar panels generate power which is then used to charge a solar battery via a charge controller in off-grid solar systems. Direct current (DC) is converted to alternating current (AC) through the use of an inverter, allowing it to power items in your home or office.

Solar power that isn’t used charges your solar battery, allowing you to use the electricity at night or when your system isn’t producing enough power.

When investing in a solar energy system for your home, one of the essential things you have to understand are the benefits and drawbacks of going off-grid.

When compared to other systems, off-grid systems offer many advantages and, of course, some limitations. Remember, being off the grid means you are entirely self-sufficient with providing energy to your home!

No power outages

When you are connected to the grid for your energy one significant issue can be blackouts. On the other hand, being off the grid enables you to have electricity even if the rest of your area does not!

Power outages can be a real nuisance, and we all prefer to have power all of the time. When you rely only on solar energy, you never have to worry about the lights going out as long as there is sunlight to keep your batteries charged!

Even on cloudy days there should be enough sunlight availability to fill up those batteries, giving convenience and peace of mind.

Significant monthly financial savings

Even though getting an off-grid system has higher initial costs, having a larger renewable energy source will save you money on utility month after month for the life of the system.

Depending on where you live and what type of solar energy system you have, the amount of money you save will vary. The easiest way to calculate this is to look at your average monthly electricity bills, which will show you what savings will be.

You can also sell energy back to the electric company using net metering, however, that would require you to still be connected to the grid.

Ideal for rural homes or mobile installation

If you live in a rural location it might not be possible to connect your property to the main power grid. In this situation, an off-grid solar system is a perfect solution!

The same goes for installing in a mobile home, RV or boat – rather than try to find electricity connections to charge your vehicle’s batteries, you can keep them topped-up with standalone solar kits.

Environmentally friendly

Most importantly, an off-grid system provides 100% renewable energy completely powered by sunshine!


Off-grid solar is more expensive

Because an off-grid package will require a battery bank, the initial costs can feel overwhelming. This is one of the main reasons some homeowners stay connected to the grid.

It can less expensive to get a smaller solar system and remain somewhat reliant on the electric utility.

No backup power source

If you live off the grid, there is always a possibility that your solar system will have some issues in the future which could leave you without power once the batteries are empty.

Because it is your solar system that has the issues, it is your problem to solve – you can’t call the utility company to fix it! This means you’ll need to research your solar system and read up on potential flaws as well as how to correct them so you can tackle problems quickly.

We recommend purchasing a high-quality system such as those sold by Eco Worthy, and also checking the warranty when you buy, and keeping up with the solar panel maintenance.

Can I make my own DIY 1000 watt solar kit?

How to make your own DIY 1000 Watt solar kit?

If you are thinking of a way to minimize your utility bills at home and planning to install solar panels, you may be considering making your own 1000-watt kit.

An off-grid or mobile solar kit with 1000 watts of solar power can provide a significant amount of electricity!

The most crucial step in making your own DIY 1000-watt solar panel kit is researching and acquiring the right components.

With an inverter and batteries, an off-grid 1000-watt solar panel kit should provide enough power for your essential appliances and devices!

Key components of the system

Evidently, the production of solar energy needs more than just panels!

A charge controller, a battery, an inverter, mounting brackets, and other essential supplies to mount and connect your off-grid DIY 1000-watt solar panel system are also required.

A solar power generator, which includes a charge controller, battery (expandable), and an inverter all in one, would be a great option if you don’t want to buy and install each component separately.

On the other hand, if you prefer the more traditional approach and intend to permanently install the various components of your solar system, we have resources to help you learn more!

Chargers, inverters, and batteries

Before purchasing your off-grid solar kit, it is essential to ensure that your charge controller can withstand the amperage generated by your 1000-watt solar panel system.

The size of your battery and inverter will be determined by your budget, as well as the amount of energy you plan to store and use. So you will need to think carefully about how many batteries for 1kw solar system will be enough for your needs.

How can I make my solar system off the grid?

If you plan to choose an off-grid solar kit, there are a few things to think through before installing solar panels on your home’s roof.

How Many Solar Panels Do You Need to Power Your Home?

1. Work out your energy needs:

You must first determine the size of your system depending on your energy requirements.

To determine your home’s average energy requirements, you can examine previous utility bills to establish your home’s usual energy usage.

To figure out the number of panels you’ll be needing, calculate your household’s monthly energy demand and your area’s peak sunlight hours, which will give you a good idea of how much solar power you can generate in relation to how much you use. It’s essential to keep in mind that the size of your roof and the amount of sunshine it receives are both important considerations!

At this step, you should also consider how you’ll attach your panels and where your panels should be mounted for optimal sunlight and efficiency.

2. Determine which appliances you need and which you don’t:

As an additional consideration after you have worked out how much energy your household uses, consider how much electricity your appliances use and whether or not you can live without them.

Lighting, air conditioners and electric furnaces, refrigerators, water heaters, electric ovens, dishwashers, and clothes dryers are the items that use the most electricity in your home. 

The more of your daily appliance use that your solar kit can power, the more sustainable your home will be!


There are so many choices for 1000-watt solar panel kits! As of now, the largest solar panel available for purchase on the market is roughly 400 watts. 

While the solar market is continually expanding with worldwide innovation assisting in advancing renewable energy, it is unlikely that a 1000-watt solar panel will be available any time soon. Despite this, it is still easily possible to have a 1kw system using solar panels already available on the market.

So, it’s never too early to start thinking about providing your home’s energy needs from a renewable and sustainable source!
