Commercial Solar: The Sweet Spot

commercial solar sweet spot


We all know that solar is the way to go in terms of renewable energy in these times of green awareness, but did you know an increasing number of business owners are heading in that direction already?

Commercial solar is a brilliant option, particularly for small businesses with monthly energy bills under $3,000. Yes, there are up-front costs, but you’ll be able to recoup your investment in less time than you think.

So… what are the benefits??

The phrases self-sustainable, clean, easy to install, flexible, efficient, and affordable immediately come to mind.

But you may not be aware that commercial solar can be a lot more cost-effective than domestic solar.

  • For a start, as businesses are generally open during daylight hours, the energy wastage is minimal. Domestic users are often out and about during the day at work and do not take full advantage of the electricity being generated.
  • Commercial premises can often benefit from a lower price per kW than in the domestic sector.
  • Domestic inverters are limited to 600V, whereas in the commercial sector, it rises to 1000V.
  • It’s cheaper to add panels to a commercial installation, as you’ll benefit from additional STCs, which can reduce your upfront costs.
  • After the initial outlay, your maintenance costs will be minimal compared to other forms of energy.


So… what size installation do I need?

Pulse will take you through all the options in deciding which system is right and most cost-effective for your particular business, but here are a few facts to bear in mind if you’re thinking of going down the solar route.

Look for the “sweet-spots” when you’re deciding on the size of the installation you need. These are milestones to be aware of in terms of cost v capacity.

  • A system of about 33kW will give you the best ratio of price/kW.
  • Once you reach around 39kW capacity, you’re just about to head into the area of significantly increased installation costs, which will, of course, take longer to recoup. However, the actual price/kW is not that different.
  • If you need greater capacity, then consider making the leap to 60kW, when the cost versus output ratio is again very attractive.
  • If 60kW is still too small, make the leap to 80kW, for similar reasons, when inverter configurations and labor costs are paid off by the returns.
  • Your next “sweet-spot” is 100kW – after which you can’t take advantage of the small-scale technology certificate zone benefits. After that, you’re in a large-scale zone, which brings with it a whole new system of costs and fees!

So… how to decide what’s right for your business?
