1000 watt solar panel kit (1KW) – off-grid application.

1000 watt solar panel kitA 1000 watt solar panel kit with the right inverter and battery bank can take your cottage off-grid. Solar power systems are still quite expensive when you compare them with the grid-supplied power. In my opinion, though, they are cheaper than generators for off-grid applications.

Why 1000 watt solar panel?

You do not need a 1000 watt solar panel kit to start your journey off-grid. But you will be off to a very good start if you start from here. A 1000 watt solar panel kit will provide a lot of power to recharge your batteries during the day fast enough to use it again at night.

What can a 1000 watt solar panel kit do?

Most solar panel kit are 24 volts systems. You can have a 1000 watt solar panel system that is a 12 volt system. The downside of a 12 volt system is that, you will be drawing more current from your batteries and as such you will loose more power to heating of your battery cables.

A 1000 watt solar panel system does not mean that all you can power is your house is 1000 watts. The 1000 watt rating only refers to the amount of power that will be returned to your battery bank from the sun light.

A 1000 watt solar panel system will deliver 1000 watts to your batteries every hour that the sun is directly over the panels. We all know that the sun will not always be over head. So depending on your location and time of the year, you may get an average of 5 – 12 hours of sunlight daily.

This means that your 1000 watt solar panel kit can theoretically deliver 5,000 t0 12,000 watts of power to your battery bank. In practice however, you may estimate for 50-70% of that. This is because the sun is only directly over your panels for about 1 hour of the day. At other times it is at an angle and your panels will not deliver the full 1000 watts.

These are not the exact components used in this video. These are the components you will need to build yours.

Cables and wood work will cost extra. At least you can work with these and get a good estimate. The 1000 watt kit from Eco-Worthy comes with the solar charge controller. You may also choose to build your own kit. It may be a little more expensive, but you will have more control.

This system runs a 6000 BTU window air conditioner, washing machine and other electronics for 10hrs daily.

Here are some 1000 watt solar panel kits.

The Ecoworthy 1kw solar panel kit is 24 volt system ideal for charging 24 volt battery array – the kit includes 6 160w solar panels as well as a 45A PWM solar charge controller, solar cable, some MC4 branch connectors pair and mounting brackets.

With 6 – 160 watt solar panels, you get about 960 Watts of power into your batteries at peak. You can expect the power to increase gradually as the sun goes up during the day. This means that if you are powering devices of say 500 watts during the day, you can have an extra 200 – 400 watts of power to charge your batteries for the night. With a system like this, you can go off-grid if you manage your power consumption closely.

  • Sturdy and corrosion resistant frame
  • One of the most affordable 1kw kits on the market


  • Instructions are slightly vague
  • Charger might be smaller than you expect – but that isn’t often an indicator of quality. An MPPT solar charge controller may be preferred by some users. The included charge controller  is adequate though.

The Renogy 1000W solar panel cabin kits come with EL tested solar modules which guarantee no hot-spot heating. Monocrystalline panels provide the most efficiency at approximately 15.4% per space.  Guaranteed positive output tolerance (0-3%); withstands high winds (2400Pa) and snow loads (5400Pa).

What to add to your Kit to make your system

In addition to the solar panel kit, you will need a power inverter and a battery bank. You will also need racks to arrange your batteries, some fuses and maybe extra cables.

To choose the right inverter, you will need to decide if you want a 1500 watt inverter, 1000 watt inverter, 2000 watt inverter or 3000-watt inverter. There are other capacities too.
