How Much Will a 100kw Solar System Produce

00kw Solar System

You undoubtedly have a huge roof and an even higher power bill if you consider purchasing a 100kw solar system in 2023. You may already own an electric vehicle or are planning to buy one.

A 10kW solar system is the most extensive home system that you can install. A picture of an earlier 10kW installation is shown below. Nothing could be wasted on this installation in terms of space! However, keep in mind that you shot this picture a while ago; in 2022, solar panels installed for 10kW systems will be substantially more efficient and pack more electricity into a smaller space, necessitating less roof space than they would have in the past.

For 10kW, how many solar panels are required?

If you use 370W solar panels, you will need 27 to build a 10kW solar system; this will provide you with 9.99kW.

You will want at least 48.6m2 of roof space because each panel will be around 1.8m × 1m in size.

This image could assist in giving you a sense of how much space that is.

What amount of power can a 10kW solar system produce?

Approximately 40kWh per day, or 14,600 kilowatt-hours per year, will be produced by a 10kW solar system. It’s a lot of electricity, enough to power two to three typical Australian homes or one inefficient home!

For comparison, 40 kWh per day will roughly run two ducted air conditioning units on a warm (or cold) day.

OR 4 little pool pumps running for 10 hours each day.

OR 40 x refrigerators with a 5-star energy rating, either with the freezer on top or below (not side-by-side; those suckers use much more energy).

How much will you save on power expenses with a 10kW solar system?

With a 10kW system, your ability to self-consume and get payment for exported power will determine how much you save on electricity costs.

In Australia, feed-in tariffs can pay anywhere between 3c and 20c, depending on the state and merchant. Let’s use 8 cents per kWh for power exports. The average person purchases power from the grid for roughly 30 cents per kWh. So let’s take a look at these three situations to understand how the payback operates:

1) Utilize all solar energy in your (massive) home or place of business: About $4500 would be saved in the first year. However, it is doubtful that a family would be completely self-sufficient; there will be periods when your 10kW system will be exporting to the grid.

2) Export 50 percent of the power to make a first-year savings of roughly $2700.

3) Export all the power; this would result in an initial cost savings of roughly $1000.

The moral of the tale is that you will accelerate your payback the more solar you self-consume.

In 2023, how much will a 10kW solar power system cost?

STCs should total around $4,460 (AKA the solar rebate). A 10kW solar system of excellent quality will thus cost between $8,500 and $13,000 to install correctly by a qualified installer in 2022.

That wide price range is because the cost of a 10kW solar system depends on the components it uses. The most expensive option will include premium panels, an inverter, and racks built by an incredibly meticulous installer. You should get high-quality parts at the lower end (but do research). You should avoid systems at the lowest end of this price range since future problems with inexpensive solar can be pretty expensive.

How long will it take a 10kW solar power system to break even?

A 9.9 kW solar system (if it’s acceptable for your situation) should pay for itself in around five years. After that, using energy is free except for a minimal maintenance fee — budget a few hundred dollars for an examination every five years — and an inverter replacement every 12 to 15 years. Payback will depend on feed-in tariff and self-consumption.

The typical time needed to pay back a 5 kWh system

No matter what state you are in, looking at the regular payback period of a 5kWh system can give you a sense of what to anticipate. It is a simple approach to determine when the system will save enough money on power bills to cover the cost of its investment.

The most effective method to accomplish this is to look at the $4,633 average cost of a 5kW system (16 rooftop panels) in Australia. Then you may split that by the system’s average annual savings, which now stands at $2,364.

A 1.95-year average payback period is the outcome.

Australian solar panel prices

Solar panel prices in Australia are not typical. The cost of solar panels will vary depending on their size. The price differs concurrently according to the state.

Different rebate pay per KW produced from one state to the next is to blame for the cost variation between them.

As a result, installation prices will differ from one state to the next. The final cost will also depend on the system’s quality and size that you wish to install.

The 5kWh solar system is the most common size. This has an average cost of $4,633 and a typical payback time of 4.2 years.
