How much does a 3KW Solar System cost?

A solar panel system with 3 kW of capacity typically costs around $9,000 — or roughly $6,300 after applying the federal investment tax credit, which can recoup up to 30% of your total upfront costs.

What is a 3KW Solar System?

These 3kW size grid-connected solar kits include solar panels, DC-to-AC inverter, rack mounting system, hardware, cabling, permit plans and instructions. These are complete PV solar power systems that can work for a home or business, with just about everything you need to get the system up and running quickly.

How many panels a 3KW photovoltaic system needs?

To calculate how many panels a 3kW Photovoltaic System with monocrystalline silicon modules needs, we can consider a single panel power of between 300 and 400 Wp. The number of Photovoltaic Modules will therefore be 8-10 panels, with a total occupied surface area of 14-17 square meters with a pitched roof and 20-25 square meters with a flat roof.

Can a 3KW Solar System be made of 300 watts?

In theory, you could design a 3kW system with any wattage of solar panel, but there are practical factors (like space needs and wiring) for you to consider. For instance, even though 100-watt panels may be cheaper than 300-watt panels, a system made of 300-watt panels would only require a third of the installation space.

Can a 3KW Solar System power a home?

(In other words, don’t expect a 3kW solar system to power an average American home’s lights, electronics and appliances.) Most solar energy companies will tell you that 3 kW of power isn't enough to cover all your electricity use, but adding a 3kW solar system to your roof or backyard can still help you lower your utility bills.

How long does a 3KW Solar System take to pay for itself?

Based on our estimated savings of $700 per year, a 3kW solar panel system that costs you $9,000 upfront would take roughly 12.8 years to pay for itself. However, if you were to apply the federal tax credit of 30% and lower your upfront costs to $6,300, the same solar array could pay for itself in about nine years.
