Things To Consider When Adding More Solar Panels To Your Existing System

5 mins read

Are you contemplating to add more solar panels to your Tampa home? It’s true that the city enjoys profuse sunshine throughout the year, but how easily you can upgrade your existing solar system depends on a number of factors. When it comes to solar panels, Tampa homeowners need to factor in aspects such as the size of the panels, condition of their existing systems, roof space and inverter capacity. Here is a deeper insight as to the things you need to consider before going for a solar upgrade:

Your Existing System

The first thing to do is to figure out the condition of your existing solar panels that are already installed on your roof top. Are they working efficiently? If the panels are underperforming, get in touch with your installer immediately to get them inspected. Ask your installer to check for a leaking or faulty junction box. You must be having a detailed user manual when you installed photovoltaic (PV) systems for the first time. Have a look at the user guide to understand what components were installed and for what purpose they were set up. If you have misplaced the manual, contact your installer and get one.

Things To Consider When Adding More Solar Panels To Your Existing System

The Inverter Size

Not all inverters are designed to handle increased number of panels, but some are. Therefore, it’s important to take a look at an inverter’s size that you have already set up. Figure out whether it can handle more power or not.

The Steps You Need to Take

Considering that your existing inverter is small and cannot handle more panels, you need to invest in another inverter. The power generated by the dual systems will be merged in your home’s AC panel. It can also be combined in your battery bank in case your system is linked to storage batteries and not to the main grid.

Here are a few other aspects that you need to factor in before upgrading your existing PV system:

  • Stick to the solar power firm that you hired for your solar installation previously. Do not get carried away by solar deals offered by new unreliable companies. The initial deal may seem lucrative but you may end up paying more in the future owing to faulty panels and components.
  • Have a word with your solar installer about the possible issues. Inform the company that you need to set up an inverter that can handle more power.


As far as solar panel shape, models, size and availability is concerned, they change with time. It’s possible that you may have to install additional panels which are somewhat different from what you’ve installed previously. This means you need to mix and match different components and equipment. If you are particular about aesthetics, consider frame color, frame depth and back sheet.

Power Ratings of Panels

If you are going for a system upgrade, i.e. adding more panels in parallel or series on an existing inverter, the panels need to have the same voltage and power ratings.

Options to Consider When Adding New Panels or Inverter Capacity

Consider reconfiguring the whole system and upgrading the inverter to a new, bigger unit that can handle more power. This is one option that you can consider if you have an old inverter or an underperforming one.

You can also set up additional panels fitted to micro inverters together with your existing PV system. You’ll enjoy a lot of flexibility as the panels are fitted with their individual inverters. Besides, you would also benefit in terms of enhanced performance.

Weigh these options carefully before you upgrade your existing system and add more solar panels Tampa has the right climate and abundant sunshine to go solar. Only ensure that you hire the best installers to get the work done professionally.
