Solar Exporters is a leading solar panel manufacturer with over 12 years of experience producing high-quality modules since 2010. This article provides key details on how to properly size a 1kW solar panel system for your home or business.
What is a 1kW Solar System?
A 1 kilowatt (1kW) solar panel system has the capacity to produce around 4kWh of electricity per day, depending on factors like sunlight availability. This is enough to power most essential appliances and lights for an energy-efficient home.
On average, a 1kW solar system consists of 3-4 solar panels, each with a power rating between 250-400 watts. The total physical size of the system is typically 6-10 square meters or 65-108 square feet. However, available installation area and panel efficiency impact overall production capacity.
Ideal Solar Panel Positioning
To maximize sunlight exposure, solar panels should ideally face close to true south and be tilted at an angle equal to your latitude. Facing even 20 degrees east or west of south will reduce energy production by 10-15%.
Panels can be roof-mounted or ground-mounted depending on space constraints. A 1kW system generally requires at least 65 square feet of unshaded area, making it suitable for smaller residential installations. Lack of shading from buildings, trees or other objects is critical for optimal solar panel output.
What Does a 1kW Solar System Cost?
The cost of a 1kW solar system ranges from around $1,200 on the lower end to $1,800 on the higher end in Australia after rebates and incentives. The main factors impacting overall price are:
- Panel Efficiency: More efficient solar panels produce more kilowatt-hours (kWh) for the same physical size. Premium brands (280W solar panels cost more but require fewer panels.
- Inverter Quality: Microinverters last longer and lead to higher lifetime energy production. High-end inverters add $500+ to the system cost.
- Additional Hardware: Custom mounting, wiring, switches and meters can drive costs up further.

How Much Can a 1kW System Save?
Assuming 4kWh of daily production from a 1kW solar system and a residential electricity rate of $0.20 per kWh, you can expect savings of around $800 per year on utility bills. With current solar panel prices, payback periods are under 5 years in most cases.
Actual savings depend on your electricity usage patterns, rate tariffs, and sunlight availability in your area. Using solar calculators helps tailor savings estimates specific to your situation.
Why a 1kW System is a Smart Starting Point
While solar panels have become extremely affordable over the last decade, the systems themselves still represent a significant investment for most households. We recommend most customers start with a 1-2kW system to offset a portion of their electricity usage without overspending upfront.
If your energy needs increase in the future, solar systems are highly modular and can be expanded by adding more panels. Many inverters even support capacity up to 15kW allowing ample room for future growth.
