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.

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.
