With the help of solar power, businesses can reduce their costs, meet their carbon reduction goals, and become more sustainable across the board. However, as businesses grow, they are likely to use more energy, too. When that happens, their existing solar panel system might not be sufficient.
If you’re wondering whether you can expand your commercial solar panel system, the answer is yes. However, it requires careful planning, so here’s what you need to consider before you start, the challenges you might face, and how Noble Green Energy can support you as you scale your energy solutions.
Why Businesses Expand Their Solar Panel System
Most businesses expand their solar PV system in response to increased energy demands which are often the result of growing operations or major shifts such as moving to a fleet of electric vehicles. Self-generating power can also be a financial decision as the savings can often allow businesses to pay back their own solar panel installation.
Companies that have already found some success in using solar to cut costs and improve energy efficiency might want to rely on it even more, whether it’s to push towards new sustainability goals or just to get ahead of the changing energy market.
Considerations & Challenges Before Solar Panel System Expansion
A solar panel expansion involves more than just adding a few panels. Here are a few things to think about as you plan:
Energy Demands
It’s recommended to perform an analysis to review your current as well as projected energy usage. This way, you can make sure what system size you need to meet your energy needs. Doing a carbon accounting review can give more insight into how scaling your solar power system can help you meet sustainability goals too.
Available Space
Solar panels require space, whether it be on your roof or on your land. If you’re already using all the space you have on your roof, ground-mounted systems and other options might make more sense. Take the time to work out exactly how much space you need for your solar panels and consider if your roof can support the additional weight of an expanded system or will it require reinforcement?
Grid Connection Capacity
One of the benefits of solar power is your ability to feed excess energy back to the grid as this often has financial incentives to go with it. However, the grid may not have enough connections right now for your planned expansion, as many grids are experiencing queues forming for solar projects.
System Compatibility
Make sure that new panels and inverters can work with your existing equipment. Your existing wiring or inverter setup may not be able to support increased capacity and might need an upgrade too so you may need to consider replacing your older system entirely.
Regulatory & Contractual Factors
You should look at any import and export contracts you have with your energy supplier to ensure they make room for additional supply. Depending on where you are and how much you plan to expand your solar setup, you might need to apply for some planning permissions too.
How To Expand Your Commercial Solar System
- Conduct a Site Survey & Feasibility Study: Engineers will have to assess your available space, structural capacity, as well as grid limitations.
- Compatible System Design: Your expansion will have to be tailored with a specific expansion plan, ensuring compatibility with existing systems.
- Compliance & Permissions: Applications are submitted to secure grid connection capacity for the increased system size.
- Installation: The process of installing new panels, inverters, and batteries involves testing to ensure they’re working and fully integrated into your system.
- Performance Monitoring: New solar systems can be connected to monitoring platforms which is included in our O&M package. This way, you (or your provider) can keep an eye on their effectiveness and efficiency.
