Choosing the Right Solar System Size for Your Business

Selecting the right solar system size for your business is a crucial decision that can impact your energy savings and environmental footprint. To make an informed choice, it’s essential to consider a variety of factors, including available space, energy requirements, usage patterns, and future needs. In this post, we’ll delve deeper into each of these aspects to help you determine the ideal solar system size for your business.

1. Assessing Available Space:

The first step in sizing your solar system is evaluating the available space for installation. Most businesses opt for rooftop solar panels, but ground-mounted or solar carpark systems can be viable alternatives. The chosen location should have an unobstructed and consistent supply of sunlight throughout the day, as this directly impacts your system’s efficiency. The more space you have, the larger the solar array you can accommodate.

2. Analysing Your Energy Requirements:

To determine your solar system’s size, you need a clear understanding of your business’s energy consumption. Start by reviewing your electricity bills to assess your average daily and monthly energy usage. Look for patterns in your consumption to identify peak demand times. This information will be invaluable when sizing your system for maximum efficiency. A commercial solar system provider can also assist you with understanding your energy requirements.

3. Factoring in Energy Usage Patterns:

Consider when your business uses the most energy. Solar panels generate electricity during daylight hours, so aligning your energy demand with solar production can optimise your savings. If your peak energy usage coincides with sunlight hours, you may be able to cover a significant portion of your needs with solar power.

4. Planning for the Future:

A forward-thinking approach is crucial when sizing your solar system. Consider your business’s growth trajectory and any potential changes in energy requirements. It’s often wise to slightly oversize your solar system to account for future expansions or increased energy demands. While this may require a higher initial investment, it can yield substantial long-term savings and environmental benefits.

5. Consulting a Solar Expert:

One of the best ways to ensure you choose the right solar system size is to consult with a professional solar provider. They can conduct a comprehensive site assessment, taking into account factors like shading, roof orientation, and expected daylight conditions. Additionally, they will analyse your energy needs and recommend the optimal system size based on your unique circumstances.

6. Evaluating Financial Considerations:

When determining the right solar system size, it’s essential to weigh the upfront costs against long-term savings. Larger systems generally require a higher initial investment but can provide a quicker return on investment (ROI) through increased energy production. Be sure to explore financing options, including solar leasing and power purchase agreements (PPAs), which can make solar adoption more accessible and affordable.

7. Considering Environmental Impact:

Choosing a solar system size that covers a significant portion of your energy needs not only saves money but also reduces your carbon footprint. The environmental benefits of solar energy include a reduction in greenhouse gas emissions and decreased reliance on fossil fuels, contributing to a more sustainable future.

An Example of Ideal Solar System Sizes Based on Your Current Electricity Costs:

The below guide may help you with determining the most ideal system size for your business, based on your current electricity costs.

Annual Electricity Costs

Ideal Solar System Size

$9,000 - 10kW – 15kW

$18,000 - 20kW – 30kW

$30,000 - 40kW – 50kW

$45,000 - 60kW – 70kW

$60,000 - 80kW – 90kW

$75,000 - 100kW – 120kW

$150,000+ - 200kW+

Please note, this information is provided as a general guide only and is based on an average daily energy usage amount at an electricity rate of $0.25 per kWh. The most suitable size system for your individual business needs to take into account all the factors mentioned above, as well as your current energy rate.

In conclusion, selecting the right solar system size for your business involves a thoughtful analysis of available space, energy requirements, usage patterns, and future needs. Consulting with a solar expert can help you make an informed decision that aligns with your business goals and contributes to a greener, more cost-effective energy future. By investing in the appropriate solar system size, you can take a significant step towards energy independence and environmental responsibility.
