How many commercial solar panels do I need?

As with any new energy source, there’s not one answer to this question. It depends on your location and how many panels you want to install. But we can give you some guidelines for setting a budget for your commercial solar panels project.

How much data do you need?

The amount of data you need to store depends on the size and number of people served by your solar farm.

  • To ensure that it will always be possible for your network to operate, you’ll want enough memory (storage space) so that all devices on the network can retain their settings and data during any power outage or other disruption.
  • The more devices connected to your network, the more storage space you need. For example: If there are ten laptops connected together in parallel rather than one laptop connected directly with another laptop, then each computer requires twice as much storage space as if they were directly connected back-to-back like they would be if they were just another pair of laptops alone—which means overall someone with 10 computers needs 130 TBs of storage!

What is the expected monthly power output?

To calculate the expected monthly power output, you’ll need to know how many hours of full sunlight your roof receives each day. If you don’t know this number, use a solar calculator to estimate it based on your location and the season. Many professional commercial solar panels Charlottesville companies can help you in calculating monthly power output.

Once you have the expected monthly power output, multiply that number by your solar system’s efficiency rating:

  • If there are no other factors affecting your installation (such as roof slope), then this is all that needs to be done!
  • If there are other factors affecting installation such as roof slope or shading trees/buildings etc., then add those into account when determining how many panels will be needed for optimal performance.Solar Calculator

What electricity rates are available for your location?

Electricity rates vary by location and can be affected by a number of factors, including the cost of electricity, your power needs and the type of solar panel system you choose. The following table shows average monthly electric bills for residential customers in various regions across the country.

  • California – $228/month
  • Florida – $155/month
  • New York City – $175/month (they actually have two separate utilities: Con Edison & Verizon FiOS)

What is the expected annual electricity output?

Now that you know what size solar panel to buy, it’s time to figure out how much electricity your new solar system will produce over the course of a year. You can use an online calculator or measure the output of your current system and use that as a baseline for comparison.

To determine this number, multiply the monthly average power production by 12 and divide that by 1,000 (the number of days in a year). For example: if you have an 8kW system with an average monthly output of 5kW per month, then its yearly energy production would be 50 kW x 12/1000 = 6kWh/day × 365 days = 2800 kWh per year.

How many days of cloudy weather do you expect each month?

The number of days you expect to have cloudy weather each month is also important. It’s not just about how much energy your panels can produce, but also how many hours they’ll be able to produce that energy.

For example, if it rains every day in your area and you want to maximize the amount of sunlight that gets collected by your solar panels, it’s best to choose a system with fewer than six months per year with less than 20% cloud cover. However, if you live where there isn’t much rain and don’t mind having cloudy days here and there (such as most parts of Florida), then this may not be an issue at all!

The number of commercial solar panel systems required depends upon several factors

It depends on how much energy you need to produce, how often it needs to be produced, and what kind of cloud cover you expect over the course of a year. The amount of energy required by your business varies depending on many factors such as:

  • The size of your building (for example, warehouses will require more power than retail shops)
  • How many people work in that building (it’s easier for a larger office building with high ceilings and plenty of windows to get lots of natural light)
  • If there are any large electrical devices (computers, TVs etc.) connected at any time during day/night hours.


While these calculations may be a bit complicated, the good news is that solar energy is one of the most cost-effective ways to generate electricity for your business. With an estimated cost of between $2 and $5 per watt installed in 2015, solar systems can save you money on your monthly utility bill while also reducing greenhouse gas emissions from fossil fuels.
