What To Consider When Investing In A 4000W Solar Panel System 

So, you’ve decided to buy a 4kw solar panel system for your home or business.

The next question is: which one should I invest in? There are many questions that need answering before making that decision – from what type of panels will work best with the space available and what size they can be, to how much they might weigh, or how much electricity you will be able to produce with them.

Size and Weight

A 4000 Watt Solar panel kit is made up of a number of solar panels which will work together to provide electricity for your home or business.

The size and quantity that you should invest in depend on how much energy you want it to produce, what type of space the panels are positioned in, as well as their weight restrictions.

For an average size solar panel to produce 4000 watts, an estimated total number of panels needed would be 13-16. This translates into a total of 24-28 square meters on your roof, depending on how much space you have available.

You should also consider the total weight of the system, and if it will be suitable for your roof type! (link to my roof article) A 4kW system is likely to weigh around 288kg, which should be evenly distributed across the roof space to ensure no damage is caused.

What You Can Run On 4000 Watt System

If you install a 4000 watt PV system on your roof or property, you will be able to produce enough electricity to power most essential household items.


  • Small AC unit
  • Fridge freezer
  • Dishwasher
  • Washing machine
  • Vacuum
  • Small heating system etc.

If you’re also planning to start an off-grid adventure, you might find the right solar generator for off-grid here that can power an AC RV fridge or DC RV fridge, LED light bulbs, an air conditioner, a fan, maybe a roof vent fan, a water pump, and kitchen appliances like a small oven microwave, coffee, or tea maker.

How Much Power Can A 4000W System Produce?

A 4000-watt solar panel system will produce an estimated 300 to 750-kilowatt hours of alternating current power per month. This is estimated on the PV cells getting 5 hours of strong sun a day, and ideally facing in the south direction.

In conclusion, a 4 kW solar panel kit is the most recommended choice for people who need a reliable and durable system. But installing a 3000 Watt solar panel system is also a cost-effective option. The price of such kits can be different depending on the quality you want to get as well as what type of installation equipment you require so it’s always best to do your research before buying anything.
