What size solar panels does your business need?

Figuring out the best solar panel size for your business doesn’t have to be complicated. Picking the right commercial solar panels is about understanding how much energy your company uses, how much roof space you have, and how much you’re willing to spend.
In this blog post, we’re diving into choosing the perfect solar panel size for your company. We’ll break down everything from figuring out how much power you need to how many panels will fit on your roof – all to help you make a good choice for the planet and your pocket.

Evaluating roof space

Getting solar panels up on your business’s roof is exciting, but before you start dreaming about all that clean energy, you need to look at your roof. Here’s how to do it without getting a headache:

Measure your roof

Grab a tape measure and figure out how big your roof is. Remember, not every square inch will be usable – you’ve got to work around vents, satellite dishes, and whatever else is up there.

Mind the Gaps

Remember that there are rules on how close you can put your panels to the roof’s edge or each other, mainly so firefighters have room to work if needed.

Check out your roof online

Many solar companies have these excellent tools that can look at your roof from space via satellite images, giving you a rough idea of how many panels you can fit. It’s not perfect, but it’s a great place to start.

Dealing with roof quirks

Vent pipes, air conditioning units, and those random bits of roof hardware can get in the way. You might have to get creative with where you put panels or move some things around.

Picking the perfect solar panel size for your business

Getting into the solar game means figuring out just the right panels for your business.

400W vs. 500W+ Panels: What’s the Deal?

Think of solar panels like batteries – some have more juice than others.

A 400W panel is like a standard battery; it works well, especially if your energy needs are moderate or if you’re a bit tight on space. These panels are great for smaller businesses or those just dipping their toes into solar power.

Then there are the 500W+ panels. These are the heavy-duty batteries of the solar world. If your business gobbles up a lot of power or you want to slash a hefty chunk off your energy bills, these might be your go-to.

They’re more prominent and pack more power, meaning you might need fewer panels overall to meet your energy needs.

But remember, bigger isn’t always better. It all comes down to what fits best on your roof and what meets your energy goals.

Figuring out how many panels you need

Now, here comes the number game – don’t worry, we’ll keep it simple.

  • Start with your energy bill – Grab your latest bills and see how much energy you use. This number is your golden ticket because it tells you how much power your solar panels need to produce.
  • Sun time – How much sun your roof gets can make a big difference. More sun means fewer panels are needed. Plenty of online tools can help you figure this out based on your location.
  • Roof real estate – How many panels can you fit up there? If space is tight, use higher-wattage panels to get more power from less area.

If your business uses, say, 10,000 kWh per year, and you’re looking at 400W panels that can generate around 1 kWh per day (remember, this depends on your local sunshine), you’ll need about 28 panels to cover your needs (that’s 10,000 divided by 365, then divided by how much one panel can generate per day).

But if each panel needs about 1.6 square meters of space, check your roof can handle all 28. If not, consider those beefier 500W+ panels, which could lower your needed number.

There you have it— just a little planning and some basic calculations, and you’ll be well on your way to a sun-powered business, saving money and the planet all in one go.
