Number of panels to be installed and required roof space for 15kW

If you had to install a 15kW solar system 10 years ago, it would be really tough and would need a lot of space. A 15kW solar power system with the latest technology in the market, where the panels between 330-400W are available, will need 37-45 panels installed with a roof space of 75-90m2. 

How much power does a 15kW solar system generate?

Solar panels are an excellent option to boost your property’s energy efficiency. In general, a 15 kW system produces 60 kWh a day, and you can utilize this information in different seasons including summer and winter if needed. However, your solar power generation totally depends on the location you reside in and the way the panels are installed on the roof. The panels need to be installed at a place where they receive maximum sunlight so that they can produce maximum output throughout the day. 

The cost of installing a 15kW solar system

Australia has one of the most affordable solar panel installation costs in the world, and 15kW solar systems, due to their size, often provide the best deal of any solar photovoltaic system size. A fully installed premium quality 15kW solar system costs around $12000 to $15000 (includes inverter like SMA and Fronius, panels like Trina and Canadian solar).  Arise Solar offers various packages considering the property requirements, we have budget friendly and premium packages available to choose from.

How much can I save on a 15kW solar system and what about payback?

You’ll save approximately $900 to $1000 per billing period if you are able to use most of the solar electricity your 15kW solar system produces. Use the majority of your energy throughout the daytime hours, when usage and power rates are highest, and your savings will grow all the more.

A premium-quality, efficient, and durable 15kW solar panel system has a typical payback time of 3 to 5 years. However, the payback period might differ based on the location of property and panels and the quality of the products installed and lastly, the price paid for it. Arise Solar is proud to offer the best 15KW solar panel system that money can buy. This package includes high quality tier 1 solar panels and an efficient 15KW solar inverter. While it’s our smallest package on offer, it provides enough power for many small businesses.

Battery storage with 15kW solar system

It is now pretty easy to install a solar battery with all the existing systems previously installed or soon to be installed, all thanks to the concept of AC coupling. It connects directly to the main supply and thus makes it simpler to connect the battery to any property. If you are looking at adding the battery along with your 15kW solar power system to consume the energy in the day and night, Arise Solar can offer amazing battery options to suit your system needs. However, what needs to be considered is that installing batteries is an expensive option as they can increase your solar system’s payback period and they come with a lot of maintenance and lower life span. 

Is it worth it to install a 15kW solar system?

Installing a solar panel system on a residential property or commercial property is always going to be worth it in Australia. When you run a business, we know how important it becomes to manage the overheads, and on top of that rising electricity costs make it difficult to control the expenses. The rebates offered by the government on installation of solar, the tax benefits and the feed in tariffs one receives for feeding back the excess power to the grid, makes it worth it to install a 15kW solar system. Generating power through renewable sources like solar energy, is one of the best moves you’ll ever make. You can lower your quarterly electricity expenses while also helping to save the environment by using solar energy. Your initial step now would be to explore your solar options.
